Webinar Series on Shorebird Identification

Willet by Shawn Billerman

The Cornell Lab of Ornithology is offering a series of webinars this fall to help people learn shorebird and waterfowl identification. This is a great opportunity for those wanting to advance in this difficult area. Kevin McGowan is a great teacher and helped me become the birder I am today. The series starts this Friday and each webinar is only $10. Space is limited.

Threatened IBA in the Dominican Republic

For those that were present for my LAS presentation on Bicknell's Thrush a few years ago (2009 I think?), you may remember that I conducted research on this thrush in the Dominican Republic. The place where I conducted this research is an Important Bird Area is now under severe threat. Please read below for more information.

IBA NEWS: PRESSURES IN THE DR

In December we ran a quick review of a new bird finding guide for the Dominican Republic, RUTA BARRANCOLI, by Steven C. Latta and Kate J. Wallace (2012, National Aviary).

Now there is news from the Dominican Republic that the Sierra de Bahoruco, an Important Bird Area (IBA) in that country is currently under increasing threat.

The area has long been suffering due to burning for charcoal production and illegal agricultural practices, and in mid-July a dry forest area on its northern foothills an area formally protected as Loma Charco Azul Biological Reserve, is starting to be cleared to make way for an agricultural settlement. This is occurring despite the fact that the area is supposed to be protected as a Biological Reserve.

The Dominican Agrarian Institute has approved this activity, and about 260 acres are slated for immediate destruction. Multiple species are at risk. The Loma Charco Azul Biological Reserve, which falls under the larger Jaragua-Bahoruco-Enriquillo Biosphere Reserve which has been ratified by UNESCO, is habitat for the endangered Bay-breasted Cuckoo (Coccyzus rufigularis), an endemic species with a very limited distribution in Hispaniola.

You can get more details on this threat and actions being taken here.

State of the Birds 2013

The 2013 report on the state of the birds focuses on birds on private lands. Approximately 60% of land in the U.S. is privately owned. Highlights of the report include:

• Through the Farm Bill’s Working Lands for Wildlife Program, more than 700 ranchers are enhancing 2.5 million acres of aridland habitat for the benefit of sage‐grouse.
• Regional spring counts of Henslow’s Sparrows are now about 25 times higher than 30 years ago, prior to the Farm Bill’s Conservation Reserve Program.
• Through Mountain Plover Nest Conservation Programs in Nebraska and Colorado nearly 250 private landowners have protected more than 1,000 nests of the imperiled Mountain Plover.

Restless Nights for Relocated Birds

When managers try to move a species to a new environment, many of the animals often die soon after being released. Now scientists have found one possible reason for the high failure rate. According to a study in Biology Letters, birds don’t get enough sleep when they’re in an unfamiliar place.

Breeding Birds of the Laramie Plains

By mid-July here in Laramie, breeding season is well under way, and for some species, already over.  While early summer can be a slow birding time in many parts of the country, things are still quite interesting and exciting here in Albany County.

Out on the plains around Laramie, many songbirds are busy feeding nestlings and fledglings.  I recently took a trip up to the Old Laramie River Road, which runs through a variety of grassland types, from the typical dry shortgrass prairie to wetter, longer grass habitats closer to the Laramie River.  This variety of grassland habitats means that this area has some of the best diversity of grassland species in Albany County, including both longspurs, Lark Buntings, and Vesper Sparrows, among many others.

Many species, including Horned Larks (Eremophila alpestris), and McCown's Longspurs (Rhyncophanes mccownii) have fledged young, and already seem to be flocking in preparation for their southward migration toward the end of August.

McCown's Longspur (Rhynchophanes mccownii) fledgling - Albany Co.

In addition to McCown's Longspurs, Old Laramie River Road is probably the best spot in Albany County to see Chestnut-collared Longspur (Calcarius ornatus).  In wetter, longer grass, this species is quite easy to find as they sing from any elevated perch.  Like McCowns, Chestnut-collared Longspurs also skylark, singing in flight, although their skylarking display is not as impressive as that of McCown's Longspur.

Lark Bunting (Calamospiza melanocorys) - Albany Co.

In addition to the great songbird activity, Old Laramie River Road has also had an exciting diversity of raptors, with many fledgling Swainson's Hawks foraging across the plains.  There have also been Red-tailed and Ferruginous Hawks, American Kestrels, and Prairie Falcons.

Ferruginous Hawk (Buteo regalis) juvenile - Albany Co.

Despite the heat of the summer, there is still quite a bit of bird activity out there, so get out there and see what you can find.  This is a really interesting time of year, and you never know what might show up.

Brown-capped Rosy-finch Survey

Brown-capped Rosy-Finch Survey in the Snowy Range Important Bird Area

July 20, 2013

Please join us for a day of hiking and bird surveying in the beautiful Snowy Mountains! We will be conducting the Laramie Audubon Society’s annual Brown-capped Rosy-Finch survey in the Snowy Range on July 20, 2013this year.

Brown-capped Rosy-Finch in Snowy Mountain IBA

In 2003, Audubon Wyoming designated a site within the Snowy Range as one of Wyoming’s Important Birds Areas because its alpine habitat supports Wyoming’s only breeding population of the Brown-capped Rosy-Finch. This bird is a species of concern because it breeds only in the Snowies and on mountain peaks in Colorado and northern New Mexico. If the current global warming trend continues, its mountain habitat islands are likely to shrink and to be invaded by other avian species that are currently excluded by the harsh conditions. Documenting how many Brown-capped Rosy-Finches are in the area and where they are feeding and nesting can help us to monitor this population and determine how the birds are faring.

This year, the Wyoming Natural Diversity Database has teamed up with Laramie Audubon to develop additional survey routes so we can get a more accurate picture of where rosy-finches occur and are nesting in the Snowies. We also will be attempting to make our data collection slightly more rigorous by using GPS units to mark our observation points and our nest locations. If you have a GPS and are willing to use it, please bring it along on the survey.

Please let Sophie know if you will be joining us on the survey and if you plan to bring your own GPS unit at 307-742-6138 or at sophie_osborn@hotmail.com.

We will meet on July 20, 2013 at 8:30am at the Forest Service Visitor Center, on WY 130, approximately 1-2 miles west of Centennial WY. After a brief orientation session, we will divide the group into teams and will divide up the survey routes.

Medicine Bow Peak area in the Snowy Mountain IBA

What to expect: Be prepared to spend the day hiking and looking for rosy-finches. The birds are not in predictable locations so considerable walking may be required. Some of the trails have fairly steep portions and the elevation can be challenging for some people. You may also spend time sitting in certain areas to search for or observe birds. Most survey routes are along established trails; a few of the new routes will be off-trail.

What to look for: In spring and summer, Brown-capped Rosy-Finches often feed at the edge of snowdrifts, where seeds that were blown onto the snowpack during winter emerge from the melting snow cover. Spring winds also blow insects from lower elevations that settle onto the snow where they can be found by birds that are gathering food for their nestlings. Nests are well hidden in talus and in shallow crevices in rock faces. When seen feeding on bright snow, rosy-finches may appear to be a solid dark color. In better light, their light-pink flanks and rumps are visible and they show a flash of pink in their wings when in flight.

What to bring: Binoculars and/or spotting scope, a field guide, warm clothes (including wind protection), lunch and snacks, water, and sunblock. Please bring a GPS unit if you have one. We will provide route maps.

Brush Creek Trail, Medicine Bow National Forest

I recently had a very lovely walk along the Brush Creek ski trail loop system which starts at the visitor center along W. C130 just west of the T intersection with Hwy C130 North. From Laramie take the C130 Centennial Snowy Range Scenic Byway all the way to the end where it bottoms out just east of  Brush Creek. (approx 1 hour)  It is a low damp area lined with spruce providing lots of cover for birds and wildlife. Clark's Nutcrackers were very common as they tamely flit just ahead of you, along with RC Kinglets. Also present were hermit thrush, chickadees, and a probable (plumbeous?) vireo. There were also quite a few butterflies including many checkered skippers, tiny blues, sulphurs, a cabbage and a mourning cloak. Also a sprinkling of some mostly white and yellow wildflowers along the wet path. All in all making for a very nice  nature hike and a good spot  for LAS  birders and butterfliers to explore. It took about 4 hours to casually hike the entire loop of about 10 miles of easy level terrain, damp and a bit muddy requiring boots. The intersections of the trail are well marked with signs and maps but bring a pocket compass to be sure of correct path to take.  Be aware of elk ( saw several) and possibly black bear. Have a real nice walk on this pretty and quiet trail.

White-tailed Ptarmigan

One of only a few species that breeds exclusively in the alpine tundra, the White-tailed Ptarmigan (Lagopus leucura) is a highly sought after bird for many visitors to the Rocky Mountains.  Unlike the other species of Lagopus, the Willow and Rock Ptarmigans which have a circumpolar distribution, the White-tailed Ptarmigan is restricted to North America.  Thought to have diverged from the Rock Ptarmigan after being isolated during the Ice Age, the White-tailed Ptarmigan is similar in many respects to other ptarmigan, with cryptic plumage appropriate for each season, being pure snowy white in the winter, and mottled brown, gray, and white during the summer (Braun et al. 1993).

 The White-tailed Ptarmigan has the most southerly distribution of any of the ptarmigan in North America (Rock Ptarmigan gets at least as far south in Japan), with their native range reaching as far south as the mountains of northern New Mexico.  Found in alpine habitats at or above treeline, White-tailed Ptarmigan can be found in areas with stunted willows, sedge meadows, and other alpine habtiats (Braun et al. 1993)  They are widely distributed across alpine tundra habitat in Colorado, and are also found in southwestern Montana and the Cascades of Washington.  Ptarmigan have also been introduced into mountains in northern Utah, the Sierra Nevada in California, and the Wallowa Mountains in Oregon.  However, despite this extensive range throughout the Rocky Mountains, White-tailed Ptarmigan are strangely absent from Wyoming.  A range map shows a large gap in their distribution in Wyoming.  Why is this the case?  Have they always been absent?

A bit of research into the history of this species reveals that White-tailed Ptarmigan used to be found in the Snowy Range, just outside of Laramie.  Regular reports of the species go back as far as the mid-1970's, with a single documented record from 2005 which may represent a dispersal event from Colorado (Hoffman 2006, Faulkner 2010, Cornell Lab of Ornithology 2012).  Anecdotal sight evidence from the Wind River Range and the Bighorns have been presented from the 1930's, but this is unverified, and subsequent searches of these areas have found no evidence of ptarmigan anywhere else in the state, despite extensive suitable habitat (Hoffman 2006). 

View of the alpine zone in the Snowy Range

 So, if White-tailed Ptarmigan were in the Snowy Range as recently as the mid-1970's, why are they no longer there?  A report prepared by Hoffman (2006) for the USDA Forest Service suggests several reasons for their absence.  First, the available habitat is very limited, and may be unable to support a sustainable population.  While there may be immigration from Colorado occasionally (as the 2005 record suggests), they are unlikely to persist.  Second, the area has high recreational usage, both from extensive snowmobiling in the winter, and hiking in the summer, which may degrade habitat.  Finally, the alpine tundra habitat was extesnsively grazed by sheep until 1997, which may have also degraded the habitat to a point that it is unable to sustain a population of ptarmigan (Hoffman 2006).

Despite there being sustainable populations of ptarmigan only 50 kilometers from the Snowy Range, and less than 10 kilometers from the Wyoming border, it is unlikely that White-tailed Ptarmigan will again have a sustained population in southeast Wyoming due to continued habitat degradation.  Why ptarmigan have never been conclusively found in the other Wyoming ranges, however, remains a mystery.  Until we learn more, we will have to be content with hopping across to Colorado and enjoying this spectacular grouse there.

Nightjar Surveys June 16-30--Volunteers Needed!

Dear Auduboners,

It’s time to start planning for this year’s nightjar surveys! Our nightjar surveys must be conducted between June 16th and June 30th. For those of you who are unfamiliar with this effort, the Laramie Audubon Society is a yearly participant in a National Nightjar Survey that was initiated in 2007 by the Center for Conservation Biology.

Nightjars are enigmatic, nocturnally-active birds whose populations are thought to be declining throughout North America. Wyoming has two species of nightjars: Common Nighthawk and Common Poorwill. In 2009, Laramie Audubon adopted five survey routes in the vicinity of Laramie (Sybille Canyon, Buford, Harmony, Fox Park, and Rock River). We will be surveying these same routes in 2013 during the established survey period.

The night surveys are fairly easy and really enjoyable. It’s great to be able to spend a few hours collecting data for an important national bird conservation effort. Surveys take no more than two hours and consist of making 10 stops along an established route. At each stop, we count the number of nightjars heard during a 6-minute period and fill out our observations on a data sheet. It is important to have good hearing to conduct these surveys. Surveys have to take place on a relatively clear night when the moon is more than 50 percent full and when there is not too much wind (these requirements can be challenging for the Laramie area!). Surveys begin at least 30 minutes after sunset and must be completed after moonrise and before moonset.  You can do the surveys alone, but it’s easier to work in teams.

If you are interested in participating in these surveys please e-mail me to let me know at sophie_osborn@hotmail.com. For those who would like to participate, I will explain the protocols and data collection, and hand out data sheets, sunset/moonrise/moonset times, and survey route maps on Tuesday June 11 at 6 pm and Wednesday June 12 at 6 pm in the Student Union – at the seating area across from the coffee shop on the main level. Hopefully anybody who is interested will be able to make one of those dates. If not, you can call me at 307-742-6138 to set up an alternate time to meet with me.

Thanks to those who decide to participate and let’s hope the weather cooperates this year!

Sophie

P.S. For those who prefer hiking and doing daytime bird surveys, we will be conducting our annual Brown-capped Rosy-Finch survey on July 20, 2012 this year. More information about that survey to come soon...

Hutton NWR & Chimney Rock Field Trip Report

On Saturday, June 1st, 14 people showed up to bird around Hutton Lake and on down to the Colorado border at Chimney Rock. It was a decent day of birding, despite not finding any active raptor nests along the ridge on the way to Chimney Rock. An unexpected bird for some was a Veery, heard at two stops adjacent to wetlands. The four checklists from the day are below.

Disappearing Toucans and Smaller Palm Seeds

One of the many uses of birds to humans is that they are pollinators and seed distributors. A recent article in Science magazine documented a decline in the size of palm tree seeds due to the decline of large-billed birds.

"As toucans and other large-beaked birds have vanished from Brazilian forests, the seeds of palm trees have shrunk, scientists report." Read more here.

Baikal Teal in Montana!

At the end of April, a birder in Montana found a Baikal Teal hanging out with some Wood Ducks near Missoula. This bird is named after where it is usually found this time of year--Lake Baikal in Russia. For some great photos by the person that found the bird, check out his webpage here.

You never know what you might find out there!
