Wildflowers threatened by "safe" levels of nitrogen pollution Article
By Jaymi Heimbuch
from Treehugger Website
from Treehugger Website
Wildflower season will be here before we know it and with it a new understanding of how we are affecting spring foliage. New science shows that even "safe" levels of nitrogen pollution -- pollution caused by the agricultural industry through nitrogen fertilizers -- have ill effects on wildflowers. While the fertilizer is a boon for farmers looking to boost crop yields, it has incredibly disastrous effects in other ecosystems, most noticeable in the gulf where agricultural run-off has triggered massive marine dead zones. And on land, wildflowers are also suffering a blow.
The Ecologist reports that a new paper written by Dr Richard Payne and Professor Nancy Dise, of Manchester Metropolitan University, and published in Proceedings of the National Academy of Sciences looks at 100 plant species in 153 grassland sites across Europe and examines their reactions to nitrogen deposition.
The scientists found that many species, particularly wildflowers such as creeping buttercup, harebell, yarrow, and autumn hawkbit, were much less abundant in areas with high nitrogen levels, such as central Britain, the Netherlands, northern Germany and Brittany. But particularly surprising was the discovery that many species declined at very low levels of pollution, often below the legally-recognised ‘safe’ level.
The findings show that even relatively "clean sites" far away from the source of pollution are still negatively affected, with a reduced abundance of some plant species. And this is no small issue. According to The Ecologist, "The scale of the problem is huge. It has been estimated nitrogen pollution costs the countries of the European Union alone up to €320 billion a year- but progress in tackling it has been limited... Nitrogen fertilizers are essential to feeding the world’s population but we can try to reduce the amount we use and the amount we lose into the environment."
While more attention is paid to the marine ecosystems impacted by nitrogen pollution, the study shows that an equal amount needs to be paid to the damages caused by the pollution to ecosystems on land -- from tropical rainforests to wildflower fields.

Do's and Don'ts for Erosion Control Article with a Preface from Howard Bright aka: Earthyman
In controlling erosion, one must start looking to the headwaters of the watershed. Sheet and rill erosion are the major contributor to siltation of our rivers. Even gently sloping land can have severe erosion if the surface is not protected by a vegetative umbrella. Native grasses are the ultimate solution to these two types of erosion. It's too late if we are already in the river up to our knees in mud and looking for a solution after the fact. Always look upstream first and then work your way down the watershed taking care of erosion problems on your way to the main river or watercourse.

Here's the Complete Article "Do's and Don't for Erosion Control"
By Susan Boyd
Shoreline Management Ranger, J. Strom Thurmond Lake
Did you know that silting can reduce the long-term depth of your cove? Silting is a natural process caused by soil erosion. Our shoreline management team is here to help permit holders and adjacent property owners resolve these issues within the laws and regulations that apply. Here’s a list of Do’s and Don’ts for how you can control erosion and prevent silting in your cove.
Do:
1. Reduce the potential for erosion by maintaining vegetated buffers around properties and bodies of water. While grassed lawns may help hold soil in place, trees, shrubs and native herbaceous plants can significantly slow the rate of erosion, as well as benefit native wildlife. (Herbaceous plants are fleshy, herb-like plants, many of which die back during the winter. They can be annuals, biennials or perennials).
2. If erosion gullies begin to develop, placing natural, woody debris in the gullies can slow the flow of water, subsequently slowing the rate of erosion. On public land, however, only dead, fallen vegetation originating on public land can be placed in gullies and ditches. Woody debris and materials from private land cannot be placed on public land. All material placed in gullies should be placed in such a manner to slow erosion, but not creating a large mound or pile.
3. Installing waterbars, drains and other diversionary measures on private land can re-direct water away from gullies and dissipate the flow of water, reducing the potential for further erosion and soil loss. Diversionary measures should be placed on private land.
4. If clearing private land adjacent to waterbodies or public land, utilize silt fences and other erosion control measures, and always obtain the necessary state and local soil erosion control permits for land-disturbing and construction activities.
5. If soil erosion has already occurred along the shoreline, it is possible to limit the extent of the erosion by stabilizing the existing shoreline. Permits can be obtained from the Corps of Engineers to place rip-rap, natural stone, and/or bioengineered materials along eroded shoreline to stabilize the shoreline and reduce the potential for future erosion.
6. If silt has accumulated in coves and along the shoreline, adjacent property owners can obtain permits from the Corps of Engineers to excavate the accumulated silt and restore natural depths within the cove.
Don’t:
1. Don’t place non-natural materials and debris in gullies and ditches. Placing non-natural materials (including treated wood) in gullies can constitute illegal disposal of waste materials and can result in water and soil pollution and contamination as materials decompose.
2. Don’t plant non-native plants and trees to control erosion. When possible on private land, always try to plant native vegetation. Many non-native plants, including the ornamentals commonly found in gardens and landscaping, can be invasive and can negatively impact natural plant and animal communities. Invasive species often out-compete and choke out native plants and trees. Only native vegetation may be planted on public land and must be approved by the Corps of Engineers.
3. Don’t clearcut buffers along streams, waterways and waterbodies. Vegetated buffers naturally slow the flow of water and reduce erosion and siltation within waterbodies.
4. Don’t conduct any shoreline stabilization, excavation or install soil erosion control measures on public land without the appropriate permits and approvals. Always contact your shoreline ranger or nearest Corps office prior to activities on public land. While many options are available for controlling erosion and removing silt from coves, all actions on public land require approval and permits.

Beguilding Beetls in the Wildflife Garden Article by Heather Holm from Native Plants & Wildlife Gardens
Beetles are a very diverse insect order and many beetles are frequent flower visitors; they are pollinators, beneficial insects predating on problem insect populations such as aphids, as well as parasitoids of other flower visitors. See similar posts about Fantastic Flies and Wonderful Wasps
The two most common flower visitors are soldier beetles (Cantharidae family) and long-horned beetles (Cerambycidae family). Beetles visit flowers to feed on pollen and nectar. Some have hairs on their tongue tip that act like pollen brushes, but typically they use their mandibles for chewing pollen grains.
Beetle Life Cycles and the Greater Food Web – It’s All Connected
Many beetle larvae are wood-boring, feeding on wood fibers or the fungus that inhabits decaying wood. By leaving dead standing trees (snags), or downed tree logs on the ground (nurse logs) in your landscape, you are providing valuable habitat for beetle larvae and the birds who feed on the larvae such as woodpeckers. Many native bee species use the abandoned wood burrows made by beetle larvae as nesting sites. Some examples include leafcutter bees, Megachile spp., mason bees, Osmia spp. and carpenter bees, Xylocopa spp.Banded Longhorn Beetles, Typocerus velutinus
Banded Longhorn Beetles, Typocerus velutinus
Common on coneflowers, this beetle feeds on pollen and nectar, their larvae are wood-boring.
Beetles can sometimes be destructive; some are not delicate flower visitors by any means, their mandibles chew on flower parts and foliage causing damage in some cases. For example, these blister beetles, Lytta sayi, are destructive feeders on legume flowers such as wild white indigo, Baptisia alba.
Many flower visiting beetles have hairy bodies where pollen grains attach aiding in the pollination of flowers. They often show a preference for white, cream or green colored flowers, with a strong, fruity or fermenting odor. The hard wings (elytra) provide some protection to beetles while they visit flowers. They are not easily scared off by other flower-visiting insects and will spend several minutes on a flower feeding on floral resources.
Locust Borer Beetle, Megacyllene robiniae
Locust borer beetles feed on pollen and are found on many goldenrod species in late summer. A possible survival strategy is to mimic wasps with black and yellow coloring, a good bird deterrent. The larvae of this beetle excavate tunnels in the wood of black locust trees (Robinia pseudoacacia).
Blister Beetles, Nemognatha spp.
These blister beetles are common on black-eyed susans, often feeding on nectar. They have strange looking mouthparts consisting of long maxillae that they use to suck nectar, they can also feed on pollen with their mandibles. Females lay their eggs on flowers, when the larvae hatch, they attach themselves to visiting bees and are carried back to the bee nests. The beetle larvae kill the bee larvae and consume the bee provisions of pollen and nectar.
Fire-Colored Beetles, Pedilus spp.
Fire-colored beetles are common flower-visitors in the spring. Larvae feed on fungi in decaying wood. Look for these beetles on flowers near woods often where blister beetles occur. Male fire-colored beetles will climb onto blister beetles, prompting them to release cantharidin, a defensive chemical. The male fire-colored beetles then lick the cantharidin off the blister beetle and use the chemical to attract females. When the male beetles mate with females, the cantharidin is transferred to the female. Her eggs are coated with cantharidin which helps protect them from predation.
PREDATION (BENEFICIAL INSECTS)
Soldier Beetles, Family Cantharidae
Soldier beetles visit flowers for pollen and nectar, they are very common in mid- to late-summer.Their narrow head, thorax, and maxillary tongue allow them to access flower nectar in fairly deep flower corollas.Considered a beneficial insect, soldier beetle larvae feed on aphids, fly larvae, small caterpillars, beetle larvae and grasshopper eggs. Some adults in this family also feed on aphids. One defense mechanism of soldier beetles is to secrete a chemical compound so they are unpalatable to predators.
Ladybird Beetles, Cycloneda spp.
Both adults and larvae feed on soft-bodied insects (mainly aphids) and are utilized in the biological control of aphids. Females can consume hundreds of aphids before laying eggs. These beetles overwinter in groupings as adults and emerge in spring. Look for ladybird beetle eggs laid near aphid clusters, often under the flowerheads.
Wedge Shaped Beetle, Macrosiagon limbatum
A distinctive, triangular-shaped small beetle. Both male and female wedge-shaped beetles are found on native plants visited by wasps (and bees), where the female lays her eggs on the foliage. When an egg hatches the tiny first stage larva attaches itself to a visiting wasp or bee. The host carries it back to its nest where the beetle larva burrow into the host larva and live as an internal parasite.The developing wedge-shaped beetle larva continues to consume its host from the inside and eventually emerges from the host body. It then proceeds to feed on the host from the outside until the host dies.
Tiphiid Wasp, Myzinum spp.
These wasps visit late summer natives for nectar. Males have a menacing looking ‘pseudostinger’ on the end of their abdomen. Females burrow into the ground and lay their eggs on scarab beetle grubs which their larvae consume as they develop.
Milkweed Leaf Beetle, Labidomera clivicollis
Milkweed leaf beetles are one of several beetles who specialize feeding on the foliage of milkweed (Asclepias) plants. Overwintering adults emerge in early spring. Females typically lay their eggs on the underside of milkweed leaves; look for bright red to orange egg clusters. Larvae hatch and develop in several instar stages during the summer months and feed on milkweed flowers and foliage. Adults are again active in the fall preparing to overwinter.

House "Sodsaver" Measure Would Protect Native Prairie Habitat
Protect Our Prairies Act would limit taxpayer-funded incentives to destroy native grasslands
02-14-2013 // Aviva Glaser
Representatives Noem (R-SD) and Walz (D-MN) today introduced legislation to save America’s grasslands through a national sodsaver provision. The Protect Our Prairies Act, which has the support of eight bipartisan co-sponsors, is common-sense legislation that would reduce taxpayer-funded incentives to destroy vital grassland resources.
Aviva Glaser, Legislative Representative for Agriculture Policy at National Wildlife Federation, said today:
“America is at risk of losing one our most iconic ecosystems. Native prairies, along with the wildlife that are dependent upon them, are disappearing at an alarming rate. The Protect Our Prairies Act will help protect this vital resource by promoting management practices that conserve native grasslands.
“Without a national sodsaver provision, we will continue to see native prairie habitats converted to cropland, despite the fact that this vulnerable land is often marginal, highly erodible, or prone to flooding. It’s time we get rid of the perverse incentives that encourage farmers to destroy native prairie for marginal financial gain.
“With this legislation we can protect vital habitat for declining wildlife and save taxpayer dollars while ensuring that some the riskiest land for crop production is kept in grazing use. It is critical that the House Agriculture Committee include this national sodsaver provision in the 2013 Farm Bill.”

Great News Global Great Backyard Bird Count Shatters Records
February 21, 2013--From Antarctica to Afghanistan, bird watchers from 103 countries made history in the first global Great Backyard Bird Count (GBBC), February 15–18, 2013. In the largest worldwide bird count ever, bird watchers set new records, counting more than 25.5 million birds on 120,000+ checklists in four days—and recording 3,144 species, nearly one-third of the world’s total bird species. The data will continue to flow in until March 1.
Building on the success of the GBBC in the United States and Canada for the past 15 years, the Cornell Lab of Ornithology, Audubon, and Bird Studies Canada opened the count to the rest of the world for the first time this year, powered by eBird, a system that enables people to report birds globally in real-time and explore the results online. Bird watchers are invited to keep counting every day of the year at www.eBird.org.
Common Redpoll by Missy Mandel, Ontario, 2013 GBBC |
Cornell Lab director Dr. John Fitzpatrick says:
“This is a milestone for citizen science in so many respects—number of species, diversity of countries involved, total participants, and number of individual birds recorded. We hope this is just the start of something far larger, engaging the whole world in creating a detailed annual snapshot of how all our planet’s birds are faring as the years go by.”
Audubon Chief Scientist Gary Langham:
“People who care about birds can change the world,” said Audubon chief scientist Gary Langham. “That’s why this year’s record-setting global participation is so exciting. Technology has made it possible for people everywhere to unite around a shared love of birds and a commitment to protecting them.”
Other Key Preliminary Findings:
Top 5 Most Reported Species (reported on highest number of checklists): Northern Cardinal; Dark-eyed Junco; Mourning Dove; Downy Woodpecker; House Finch
Top 5 Most Common Birds (most individuals reported): Snow Goose; Canada Goose; Red-winged Blackbird; European Starling; American Coot
Finch Invasion: A massive number of northern finch species moved into the U.S. including the Common Redpoll, reported in a record 36 states. Scientists believe these periodic movements are related to natural fluctuations in crops of conifer cones and other seeds in Canada.
Hurricane Sandy: The weather system that caused Sandy's landfall also blew some European birds to North America and evidence of this is still showing up in GBBC results. The colorful, crested Northern Lapwing was reported in Georgia, New Jersey, and Massachusetts during the GBBC.
GBBC First: A Red-flanked Bluetail has wintered at Queens Park, Vancouver, and was also reported for the GBBC’s first record ever. This British Columbia bird has been drawing bird watchers from all over the U.S. and Canada hoping to see this rarity. This little thrush is one of the only birds in the world with a striking blue tail and is native to Asia; the other GBBC report of this species this year was from Japan.

Restoring the Landscape with Native Plants Article Grass-carrying Wasps ~ Isodontia spp.
Grass-carrying wasps are a flower-visiting solitary wasp, common in late summer and early fall. Because they are solitary-nesting, and not colonial like yellowjackets or hornets, they do not sting humans to defend their nests. It's an important distinction to make with wasps in our landscapes, so many are solitary and not aggressive.
They perform important ecosystem services, pollinating the plants in our landscape, and preying on foliage eating insects, crickets and katydids in particular.
Females look for prey, stinging them several times to paralyze and immobilize them. They carry their prey back to their nests, which are preexisting cavities such as hollow stems or holes bored in wood.
The paralyzed prey are stocked for their developing larvae to feed upon. Using nearby grasses, nests are divided into sections with pieces of grass, they also close the end of nest with grass.
If you erect a mason bee nest board (board with nesting holes drilled in it), grass-carrying wasps will sometimes build nests in the cavities. Look for pieces of grass sticking out the ends of the board holes or plant stems.
I have several different variations of stem nests hung in the yard for solitary bees (and wasps), this one in particular has been utilized almost exclusively by grass-carrying wasps. Cup plant and pale Indian plantain stems work extremely well, both are hollow.
Here's a cross-section of one of those stems with the wasp larvae and stocked prey. In my yard, the grass-carrying wasps like to use little blue stem to seal off the cavities.
Look for grass-carrying wasps in late summer. In my yard, they like to visit stiff goldenrod, common boneset and pale Indian plantain flowers for nectar.

[Wren Song] 90 Article The Travelling Wildflife Gardener
What a week! I think I had a very successful talk at the Longwood Gardens Today’s Horticulture Symposium on Friday. I got a lot of positive feedback from both the conference organizers as well as many audience members.
I also got to meet for the first time in person my team member Suzanne Dingwell. I’ve known her for years “online” but it was so exciting to get to spend some time with her during this conference.
And I shared a wonderful lunch with one of my biggest fans, Damon Morris and other members of the Mount Cuba Center staff. All in all a wonderful day!
I’m getting ready for my grand birding adventure in Trinidad and Tobago, such an exciting way to spend my 20th anniversary, but this week I also got invited to participate in a FAM tour to Guatemala, another wonderful birding adventure in such a beautiful place! (A FAM tour is when the tourist bureau or other organizations bring you to their country to familiarize you with the many wonderful things to see so that you’ll help to promote them).
This particular tour will be led by some of the best birders in Guatemala where I’ll get to see many of “our” birds in their winter habitats, as well as get to know many of the gorgeous birds who reside in Guatemala year round. I am so excited! Two tropical birding vacations in less than a month. Yippee!!!
And many, many thanks to the nature angels who have donated so many wonderful books and other supplies to the classroom I’ve adopted to teach them about birds, nature, and other wildlife. You have truly blessed my life as well as enriched the lives of the students in my class (an inner city 4th through 6th grade special assistance classroom who have very few resources for learning. Thank You!!!

The Prairie Ecologist Article: Thank Goodness for Boxelder Bugs
By Chris Helzer The Prairie Ecologist
I finally broke down and bought a close-up flash system for my camera. Until now, I’ve just relied on natural light to illuminate the flowers, insects, and prairies I photograph. However, during the last couple years, I’ve been weakening, and looking at recent images from people like Clay Bolt and Piotr Naskrecki finally pushed me over the edge. After considerable wandering about in the world of internet photography websites and equipment reviews, I am now the owner of a Nikon R1 Wireless Close-up Speedlight Kit. (Say THAT five times fast!)
Here’s my next problem: Now that I’ve got a flash system to help me get better close-up insect photos, where am I supposed to find an insect to photograph during the middle of February in Nebraska??
Enter the friendly neighborhood boxelder bug…
A boxelder bug captured on my front porch and photographed in my kitchen.
I’m sure I’m not the only one who has been seeing boxelder bugs around their house this winter. It seems there are always a couple of them nearby - soaking up some sun by the window or reading over my shoulder at by the desk. Sure enough, as soon as I got the new flash assembly hooked up and ready to test, I was able to find one boxelder bug in the kitchen and another out on the front porch. (You can tell which is which in the photos because the bug from outside is covered in dust.)
The other boxelder bug – less dusty – that I found in my kitchen.
Boxelder bugs are considered by many people to be pests, but that’s not a completely fair characterization. Sure, they suck the juices out of leaves and the developing seeds of boxelder and maple trees, but they don’t siphon enough out to actually hurt the trees. Yes, they can congregate in large numbers on the sunny sides of houses, but they’re not doing any actual damage there. Also, while they are happy to spend the winter in cozy crevices around your house, they don’t eat anything during that time, and can make themselves available on short notice should you have the urge to try some wintertime insect photography in your kitchen.
As the photo shoot went on, the boxelder bugs and I got more creative in our portrait compositions. (Also, this one didn’t want to hold still.)
The species of boxelder bug in my neighborhood is the Eastern Boxelder Bug (Boisea trivittata), which is found throughout most of the United States east of the Rocky Mountains, as well as in some western states, parts of southern Canada, and even Central America. Boxelder bugs are “true bugs”, meaning they are members of the taxonomic order Hemiptera, along with other bugs such as stink bugs, plant bugs, cicadas, and many other insects that have piercing/sucking mouth parts. Like many other true bugs, boxelder bugs also have a characteristic triangle between the tops of their wings (as opposed to beetles, in the order Coloeptera, which have hardened forewings that form a hard shell on their back when they’re not flying.)
They’re even cuter from the front, aren’t they?
One of the endearing qualities of boxelder bugs is that they can release bad-smelling/tasting chemicals to discourage predators. Like many other insects with similar capabilities (monarch butterflies and long-horned milkweed beetles, for example), they have bright orange or red markings to warn predators off. That defense mechanism may be why boxelder bugs feel comfortable hanging around – often in large crowds - in plain sight, while most other insects work hard to stay hidden.
Last shot. Note the small eyes behind each of the main eyes. Those smaller eyes are ocelli, or simple eyes, that (we think) can discriminate only between light and dark. Their function is still a topic of debate among entomologists.
Plus, they make very accomodating photo subjects in the dead of winter.
Photography notes for those of you who care… These photos were all taken with the “standard” set-up of the R1 system, with two speedlight flashes, mounted at “9 and 3″ at the front of my Nikon 105mm macro lens. I had an 8mm extension tube on for all but the second photo shown here. The bugs were photographed walking around on the white plastic (acrylic?) diffuser that came with the flash system. All these shots were hand-held at 1/250 sec exposures. I’m looking forward to using this flash system outside, so I can capture images of insects, flowers, and other small things when the available natural light isn’t quite as good as I might want. We’ll see how that goes.

Wildlife Diversity News A Publication of the Iowa DNR Wildlife Diversity Program Perfect Day in the Field
Edited by Erica Eaves
Wildlife Diversity News
A Publication of the Iowa DNR Wildlife Diversity Program
Perfect Day in the Field
It was a gorgeous day to be outside, especially for August. Yesterday it was 100 degrees in the shade, and the day had been spent near the southern border of Iowa searching for evidence of nesting birds for the Breeding Bird Atlas. Today was being spent in the field, too, only the location had changed to northern Iowa in Floyd County. It rained last night, and the temperature was 30 degrees cooler this morning. It seemed a good day to visit the woods, so the search was on for birds in oak woodlands along a scenic stretch of the Cedar River – at Idlewild Wildlife Area. The birds seemed to be celebrating the rain and coolness. Family groups were busily feeding, and many birds were singing. While walking a trail along the Cedar River, the characteristic tea-kettle, tea-kettle, tea-kettle song of a Carolina Wren was heard emanating from a nearby shrubby area on the bank of the river. As the singing bird was approached, food–begging calls of a young wren were heard, and a family group of Carolina Wrens was quickly spotted. One adult wren held a squished green caterpillar in its bill, and a persistent youngster badgered the adult until it finally gave in and delivered the food package to the youngster’s gaping mouth.
While enjoying the antics of the wren family, another family group was observed foraging for insects about 25 feet beyond the wrens. A pair of Black-and-white Warblers and their 3 stub-tailed youngsters were busily picking bugs from the stems and leaves of some dogwood shrubs. Above the feeding birds stood a massive White Oak tree with large horizontal branches. The family group of warblers soon were seen gleaning insects on the trunk and lower branches of this wonderful old oak tree. A family of rather loquacious Black-capped Chickadees also inhabited the oak tree, and they made it a point to scold the human intruder who was observing them. Upon closer scrutiny of the contents of the oak tree branches, it was discovered that the tree was alive with bird activity. Families of Downy Woodpeckers, White-breasted Nuthatches and Eastern Wood Pewees were all busily bugging. A ticked-off Red-eyed Vireo, a male Baltimore Oriole and a small gang of Blue Jays joined the chickadees voicing their displeasure with the human’s presence. Other birds in the oak tree voicing irritation included a pair of Red-bellied Woodpeckers, a male Hairy Woodpecker, and a male Northern Cardinal. A male American Redstart also joined the group, but he seemed more intent on capturing a meal than wasting energy scolding.
The early morning light, filtering through the branches of the oak tree, was nearly perfect for observing details of the various bird behaviors. The whole scene seemed a bit surreal, and the glistening leaves, still damp from the earlier rain-shower, formed an interesting back-drop for the flitting birds - with flecks of red, blue, orange and yellow dotting the various shades of green offered by the tree’s canopy. The colorful animated show, along with a cacophony of bird songs and sounds, was rather like attending a bird circus. This was indeed a memorable outing and the kind of day that an admirer of birds lives for.
After five glorious years in the field gathering data for Iowa’s Breeding Bird Atlas, this was the last day spent in the field by this particular observer. Not being one to believe in coincidence, this observer feels very fortunate to be blessed by such an extraordinary and perfect day - spent happily amongst the feathered-beings with whom we share our earth-home.

News Release: Great Backyard Bird Count Goes Global Feb. 15-18
Bird watchers worldwide invited to participate online
February 5, 2013—For the first time, anyone anywhere in the world with Internet access can participate in the 16th annual Great Backyard Bird Count (GBBC) February 15-18. Participants simply watch birds at any location for at least 15 minutes, tally the numbers of each species they see, and report their tallies online at www.BirdCount.org. The GBBC is a joint project of the Cornell Lab of Ornithology and Audubon, with Canadian partner Bird Studies Canada.
This year, anyone visiting the GBBC website will be able to see bird observations pouring in from around the world and contribute their own tallies. Global participation will be made possible thanks to eBird, a real-time online checklist program that the Cornell Lab and Audubon are integrating into the GBBC for the first time this year. The GBBC is open to anyone of any skill level and welcomes bird observations from any location, including backyards, national parks, gardens, wetlands, and urban landscapes. The four-day count typically receives sightings from tens of thousands of people reporting more than 600 bird species in the United States and Canada alone.
"We're eager to see how many of the world's 10,240 bird species will be reported during the count this year," said Cornell Lab director John Fitzpatrick. "We're looking forward to this historic snapshot of birds that that will be reported from around the world. We need as many people as possible to help build the wealth of data that scientists need to track the health of bird populations through time."
Participants will be able to view what others are seeing on interactive maps and contribute their tallies for ongoing bird research and conservation efforts. For the first time, participants will also be able to upload their counts from the field using the eBird BirdLog app for Apple or Android smartphones. To celebrate the new global reach of the count, developers of the eBird BirdLog app are offering regional versions of the app for just 99 cents through February 18. Learn more
Just how big is this year's irruption of northern finches and other species such as the Red-breasted Nuthatch? GBBC reports will help define the answer. Photo by Christine Haines, 2012 GBBC. "This count is so much fun because anyone can take part, whether you are an expert, novice, or feeder watcher," said Gary Langham, Audubon’s Chief Scientist. "Invite new birders to join and share the experience. Once you get involved, you can continue with eBird year round."
"The popularity of the Great Backyard Bird Count grows each year," said Dick Cannings, Senior Projects Officer at Bird Studies Canada, "and with the new features, participation will be even more exciting."
Participating is easy. To learn more about how to join the count, get bird ID tips, plus downloadable instructions, web buttons, and flyers, visit www.BirdCount.org. The count also includes a photo contest and a prize drawing for participants who enter at least one bird checklist online. Portions of the GBBC site are also now available in Spanish at www.ContandoAves.org.

Cedar Valley Home & Garden Article Going native: Start your own wildflower garden from scratch
Going native: Start your own wildflower garden from scratch
The coneflower is a given when compiling lists of popular wildflowers.
This prairie plant is beloved for its easy-going nature and long-lasting daisy-like blossoms blooms. It attracts bees, butterflies and other insects into the garden, and it's fun to watch goldfinches dangling upside down dining on seeds plucked from spent heads.
Narrow-leafed purple coneflower (Echinacea angustifolia) is an Iowa native, along with pale purple coneflower (Echinacea pallida) and purple conflower (Echinacea purpurea). A few areas of Iowa, mostly on our western edge, you'll find the yellow prairie coneflower (Ratibida columnifera) and the grey-headed prairie coneflower (Ratibida pinnata).
Black-eyed and brown-eyed Susans are prized, along with columbine (Aquilegia canadensis) with its cheerful red and yellow nodding blooms, wild bergamot (Monarda fistulosa) and butterfly weed (Asclepias tuberosa). New England aster (Symphyotricum novae-angliae, previously Aster novae-angliae) is among my personal favorites, and the first type of aster I ever planted. Monarchs passing through my fall garden find it a valuable source of nectar (and a landing pad to rest).
Search out a source for high-quality seeds and plants that are suited to your growing conditions --- location, soil type, sun exposure, etc. The National Garden Bureau, which has declared 2013 the "Year of the Wildflower," also suggests tracking down fact sheets and publications geared toward your geographic region, such as the Xerces Society (www.xerces.org) and the Lady Bird Johnson Wildflower Center's extensive database that can be searched by state (www.wildflower.org). Iowa State University Extension also has good resources for wildflower information.
To create your own wildflower garden, follow these NGB suggestions:
1. Prepare the soil by removing weeds and other unwanted vegetation. If the soil is compacted, till lightly so the soil is loose and germinating seeds can put down roots. A bow rake is great for loosening the top layer of soil. Digging or roto-tilling too deep will bring up weed seeds and other plants that will need to be removed later to avoid competing with the wildflower seeds. While it may not be practical or necessary to amend the soil before planting wildflowers, you can add organic matter such as compost or well-rotted manure before planting depending on the site.
2. Wildflower seed and seed mixes can be planted in either spring or fall. Spring rains help seeds germinate and plants get established before many weeds have a chance to grow. In cold climates, a dormant seeding of wildflowers can be done in the fall when temperatures are low enough that seed will not germinate until weather warms up the following spring, similar to what happens in nature. Some seeds, especially many of our native perennial wildflower species, need a chilling period to break their dormancy. This is provided naturally by the change in temperatures from winter into spring.
3. Scatter seeds by hand or with a small spreader. Seeds can be raked into the soil or lightly covered with soil. Water thoroughly right after planting and keep seeds and seedlings moist for about 4-6 weeks. Gradually reduce watering as seedlings develop. Identify and remove weed seedlings as soon as possible since they will compete with wildflowers for water, nutrients and space. For dormant seeding, watering after planting seeds is not necessary.
Care & feeding
Annual flowers are more abundant at first because they grow and flower quickly. Perennial plants will follow and eventually become established; many annual and perennial plants may reseed themselves.
Year one: Not all seeds will germinate right away, especially perennial wildflowers. Don't be disappointed if there is no "instant" meadow. For more immediate results combine seeding wildflowers with planting a few container-grown plants. Plants will quickly get established and compete with weeds that may appear.
Identify and remove weeds when small to prevent spreading. Wildflowers may need additional water if rainfall is sparse, especially during extended heat spells. Avoid cutting flowers so they can seed and fill in the garden next year.
Year two: You'll see new plants from seed that didn't germinate the first year. Water if rainfall is inadequate, especially in spring or hot we ather. Remove weeds as they appear. As flowers become established, weeding will lessen. Fill in bare spots with seed or container-grown plants.
Year three and beyond: Minimal maintenance; remove weeds that may move in. Move plants that are too close or overcrowded and use them to fill in bare spots or sow more seeds. You may need to water if there is an extended period of heat. Fertilizing is generally not required.
In the garden setting, you can mulch around plants with compost or well-rotted manure. Mowing or cutting wildflowers to about 6 inches high will spread seeds and keep the garden looking neat. You can dig or rake the soil to regenerate a wildflower garden by improving contact between soil and seeds that have dropped to the ground.

The Prairie Ecologist Article Photo of the Week A red-bellied woodpecker - January 3, 2013
By Chris Helzer/The Nature Conservancy
This photo was taken several years ago outside the house of my in-laws in eastern Nebraska. I don't usually photograph birds, but I was there and the birds were there, and one thing led to another...

It was snowing, but the mid-day light was still bright enough for photography. As the snow fell, I stood in my coveralls near several bird feeders, hoping the birds would ignore me. I had covered my camera in a plastic bag and wrapped my lens in cardboard (held on with rubber bands) - only the best technology for me! While the snow piled up on my camera, eyebrows, and beard, I pivoted the camera around on my tripod, attempting to focus on bird after bird as they came near the feeders. Most of the time, of course, the bird either landed in a non-photogenic spot or moved away before I could get a bead on it. In spite of that, I eventually managed to get a few useable shots.
This one is my favorite from the day - mainly because of the completely white background. It would look like a studio shot except for the blurry snowflakes coming past the tree trunk. In reality, the snow on the ground and in the air behind the bird just blurred together into a pure white background.

Earthyman Responds to a Customers Question on Advice on Planting Butterfly Milkweed : Asclepias Tuberosa Seeds
Question: Hi. I recently received 6 packets from you of Butterfly milkweed. Could you provide some advice on planting? I have a small flower garden ( full sun,) as well as 15 acres of various prairie plants and grasses. Began as all switchgrass but I am slowly planting more and more grasses and forbs. Thanks. Stan
Response: Stan, you may start the seeds indoors after you have moist stratified them. Place the seeds in a zip lock back mixed with moist vermiculite. Leave them in a refrigerator for 30 days. Remove and plant in open flats or small pots with sterile soil medium at a depth of 1/8th to 1/4th inch. They must receive considerable light and warmth to adequately develop. Once they have started to form the white root, they can be transplanted to your garden or field. Keep the competition down from weeds and other plants. They prefer well drained to excessively drained soils in full sun. They do well in rocky poor soils with maximum exposure to the sun and wind. If you want to do a dormant seeding, you may spread the seed now or anytime the ground is exposed. Make sure your seeds are not on frozen ground as they may wash away. Wait until the ground thaws and spread your seed but only lightly cover with a sprinkling of soil or compost no deeper than 1/8 to 1/4 inch. Nature can then freeze and thaw offering the best stratification. Once plants are mature, you must be very careful when you attempt to transplant as the roots are very massive and at least 90% of the roots should be dug with plant and immediately transplanted. You should start seeing blooms the second year and thereafter the plants will grow much stronger and have many blooms in the following years. If your plants, for some reason die or disappear the following year after planting, they are probably in a poorly adaptable site for this species.
Thanks,
Howard aka "Earthyman"

Why Are Some Wild flowers Highly Scented with Brightly Colored Petals?
Thought You Might Enjoy this Q&A From Ask.com regarding Wildflowers
Question: Why Are Some Wild flowers Highly Scented with Brightly Colored Petals?
Top Answer: Some wild flowers are highly scented with brightly colored petals so as to attract pollinators like insects and birds. The pollinators feed on the nectar and help in distribution from pollen grains from anthers to stigma of the same plant or another plant. This enables continuation of reproduction.

Restoring The Landscape With Native Plants Tall Beard Tongue Insect Visitors
Article Written by noreply@blogger.com (Heather Holm) on Dec 07, 2012 03:16 pm
Tall Beard Tongue ~ Penstemon digitalis
Beard tongue flowers have a large, hairy staminode on the lower half of the tubular flower which restricts access to bees to the flower and helps in pollen deposition. Small to medium sized bees are the most frequent visitors.
Tall Beard Tongue flowers can be white to light pink, sometimes with darker pink to purple stripes which act as nectar guides for bees.
Small Carpenter Bees (Ceratina spp) visit Tall Beard Tongue flowers primarily to feed on pollen. Their small size allows them to easily climb over the staminode into the tubular flowers to access the pollen on the anthers.
As they feed on pollen, they often inadvertently contact the stigma. The hairs on the staminode keep their bodies held closer to the stigma, resulting in more contact and pollen transfer.
Digger Bees (Anthophora spp.) are frequent visitors to Tall Beard Tongue flowers as well. They are fast moving and visit flowers for a very short time frame compared to Small Carpenter Bees.
Their medium sized bodies and long tongues allow them access into the tubular flower which results in abundant pollen removal as their bodies scrape on the anthers above.
Bumble Bees (Bombus spp.) are not primary pollinators of Tall Beard Tongue. Visiting the flowers for nectar, they are able to reach the nectar reward with their long tongues without having to insert their body into the corolla and come away with pollen on their bodies.
Look for small holes chewed at the base of the flower. Mason Wasps will chew holes to reach the nectar reward without having to enter the flower. Smaller bees will take advantage of these nectar thievery holes.
