Laramie Conservation Expo

Laramie Audubon will be at the Conservation Expo tomorrow!

When: 9 am - 3 pm, Feb 9, 2013

What: The Laramie Conservation Expo promotes a responsible conservation ethic in the community by helping citizens learn about tools and methods to conserve water, energy and other resources. Participants can learn about such practices as composting, growing your own food, installing a wind turbine, purchasing a hybrid vehicle, water-efficient landscaping or building an energy-efficient home. More than 60 exhibitors, representing business, government, nonprofits and home practitioners, will give demonstrations and answer questions.

Vendors will display products to help with landscaping, green building, alternative energy, alternative transportation, recycling, local foods and environmental education. Government agencies and local nonprofits will explain their services. Experts will give presentations on smart energy choices, local foods and other topics.

Where: Albany County Fairgrounds Activity Center, 3520 US Highway 287, Laramie

Cost: Free and open to the public.

For more information, call (307) 721-0072 or visit www.lrcd.net or www.uwyo.edu/enr/upcoming-events.

Extinction before Identification?

From this week in Conservation Science by Conservation Magazine:

"Dour predictions that extinctions will outpace efforts to name Earth’s species are unfounded, scientists argue. With the help of amateurs and online tools, they say, researchers could catalogue most of the planet’s flora and fauna within a century." Read more here.

For more on how to get involved with online scientific opportunities for amateurs, here is a list from the most recent Audubon magazine:

Seafloor Explorer: mark bottom-dwelling creatures on the seafloor
Cyclone Center: help classify 30 years of cyclone images
Whale Fm: help identify whale songs
Old Weather: transcribe weather records from mid-19th century ship logs

Grassland Birds & Black-tailed Prairie Dogs

Here is the abstract from a recently published scientific paper with interesting results showing differences in the grassland bird community on and off prairie dog colonies.

McCown's Longspur by Shawn Billerman

Augustine, D. J. and Baker, B. W. (2013), Associations of Grassland Bird Communities with Black-Tailed Prairie Dogs in the North American Great Plains. Conservation Biology. doi: 10.1111/cobi.12013

Colonial burrowing herbivores can modify vegetation structure, create belowground refugia, and generate landscape heterogeneity, thereby affecting the distribution and abundance of associated species. Black-tailed prairie dogs (Cynomys ludovicianus) are such a species, and they may strongly affect the abundance and composition of grassland bird communities. We examined how prairie dog colonies in the North American Great Plains affect bird species and community composition. Areas occupied by prairie dogs, characterized by low percent cover of grass, high percent cover of bare soil, and low vegetation height and density, supported a breeding bird community that differed substantially from surrounding areas that lacked prairie dogs. Bird communities on colony sites had significantly greater densities of large-bodied carnivores (Burrowing Owls [Athene cunicularia], Mountain Plovers, [Charadrius montanus], and Killdeer [Charadrius vociferus]) and omnivores consisting of Horned Larks (Eremophila alpestris) and McCown's Longspurs (Rhynchophanes mccownii) than bird communities off colony sites. Bird communities off colony sites were dominated by small-bodied insectivorous sparrows (Ammodramus spp.) and omnivorous Lark Buntings (Calamospiza melanocorys), Vesper Sparrows (Pooecetes gramineus), and Lark Sparrows (Chondestes grammacus). Densities of 3 species of conservation concern and 1 game species were significantly higher on colony sites than off colony sites, and the strength of prairie dog effects was consistent across the northern Great Plains. Vegetation modification by prairie dogs sustains a diverse suite of bird species in these grasslands. Collectively, our findings and those from previous studies show that areas in the North American Great Plains with prairie dog colonies support higher densities of at least 9 vertebrate species than sites without colonies. Prairie dogs affect habitat for these species through multiple pathways, including creation of belowground refugia, supply of prey for specialized predators, modification of vegetation structure within colonies, and increased landscape heterogeneity.

More Mimickry!

I came across a couple of amazing examples of birds mimicking human speech on Buzzfeed and wanted to share the videos with you all! It seemed particularly apropos following Julie's post on mimickry.
First, an amazing Common Myna named Kaleo who was raised by a human from the age of about 3 days old:

Here is another myna making an appearance on The Johnny Carson Show (some of you may remember Jack Hanna of the Columbus Zoo appearing on late-night talk shows with a host of animals- seeing him on TV as a child was one of the reasons I became a biologist!) :

And finally, Pepper, a European Starling that was rehabilitated after being found at a very early age with a broken leg, making an incredible array of vocalizations:

More on the CBC

Fellow board member Anika pointed out this recent podcast from Science Friday about the Christmas Bird Count. For more information on the CBC check out the National Audubon site. More locally, Eve Newman, Outdoors reporter for the Laramie Boomerang, accompanied my team the day of the count and wrote an article about this year's event in Laramie.

A Not So Silent Spring

I came across this article from Conservation Magazine yesterday, albeit a couple years old, but it's very interesting. The article is about birds incorporating human noises into their vocal repertoire.

A male European blackbird was terrorizing the neighborhood. For several months, he started singing at around 5 a.m. each day, but this was no ordinary song. The bird imitated the sounds of ambulance sirens and car alarms at a jarringly life-like volume. It even produced cell-phone ring tones that went unanswered for hours.

The tale of the annoying blackbird in Somerset, U.K., was not unique. Hans Slabbekoorn, an assistant professor of behavioral biology at Leiden University in The Netherlands, had heard similar stories—but he was skeptical that such bizarre reports could be true. So he started asking people to send him recordings of the off-kilter blackbirds. Sure enough, what he got back was pitch-perfect imitations of urban noises, including not just sirens and car alarms but even the distinctive sound of a golf cart backing up—mimicked by blackbirds living near a golf course.

While the sounds seemed artificial, the reason birds were making them was surprisingly natural....continued here.

The Laramie CBC results are in!

Gray-crowned Rosy-finch by Shawn Billerman

Laramie's Christmas Bird Count was held December 15, 2012 with 38 participants working in 15 teams. There were 50 species and 4851 individuals observed. The weather was the best we've had in years: overcast with scant wind.  Highlights included crossbills, rosy-finches, redpolls, and a few lingering blackbirds.

Specimens, Bald Ibis, and Razorbills

Northern Bald Ibis or Waldrapp
(Wikimedia Commons)

In my morning perusal of The New York Times, I came across this 2011 series on collecting. I thought it might interest others and it relates to our December public talk.

At the same time, my fiance was reading his Swiss newspaper and came across a story on a Northern Bald Ibis that took a wrong turn in migration this year and ended up in Spain. The Northern Bald Ibis, or Waldrapp, is a critically endangered species that, unlike other ibis species, prefers to nest on cliffs in arid regions. For more on this interesting species, check out the website here (click on the British flag for the English version).

And that story reminded me of a recent article I read on the eBird site on an invasion of Razorbills in Florida this winter. There must be something wrong when a pelagic seabird from the north shows up in numbers in tropical waters. You can read about the Razorbill invasion here.

Please welcome our new board members!

Is this 'Bird Armageddon'?

Since 1966 UK bird population has decline by 44 million which amounts to just under a million birds a year (over 45 years), which is dismal November news indeed.

Yesterday (November 19th) the RSPB published their most extensive survey of the UK’s bird populations over the last 4 decades (including data from 2011); ‘The state of the UK’s birds 2012’. SUKB2012, as it is also known, is a collaborative affair between NGO’s and the UK’s governmental nature conservation agencies: RSPB, BTO, WWT, NE, NIEA, SNH and JNCC. The report uses a mix of indicators to assess the populations of wild birds, seabirds and wintering birds throughout the UK and overseas territories. All species are given a conservation status (red, amber or green) in accordance with the criteria set out in the BTO’s document Birds of Conservation 3, 2009.

UW Collections Manager, Talk & Tour, Nov 28

Dr. James Maley to talk about rails and give a tour of the University’s vertebrate collections: We have all heard of splitters vs. lumpers when it comes to dealing with bird species, but how do scientists determine whether two species really should be lumped together as a single species or whether a single species should be divided into two or more? Dr. James Maley, Collections Manager for the University of Wyoming’s Museum of Vertebrates, will touch on this issue as he discusses his Ph.D. research on the very similar Clapper and King rails during the November public meeting. James used morphology (the study of the form and structure of organisms), genetics, and ecological adaptations to salt vs freshwater marshes to better understand what differentiates Clapper and King Rails--in essence what defines them as species. He also used specimens housed in museums throughout the United States to understand the genetic diversity of the Clapper/King Rail complex, often using scrapings of toe pads from specimens when tissue samples were not available. After his talk, James will provide a tour of the collections at the University of Wyoming Museum of Vertebrates to highlight the importance and utility of bird specimens for avian research and conservation.

We will also be holding a public vote: At this meeting, our members will vote for three new Board Members (Anika Mahoney, James Maley, Vicki Henry), President (Sophie Osborn), Vice President (Brian Waitkus), and Secretary (Julie Hart) at the meeting before the program.  If you are unable to attend, please email your vote to laramie.audubon@gmail.com.  Thanks for your support!

When & Where: Wednesday, Nov. 28, 6:30pm Bird Chat & Refreshments, 7:00pm Short Business Meeting & Program, UW Berry Center, corner of 10th & Lewis Streets.

LAS Raptor Trip – November 10, 2012

Despite threats of snow and wind and cold, eight stalwart Laramie Auduboners ventured out to look for raptors in the Laramie area on November 10. We were lucky with the weather as well as with the birds. The snow stopped, the wind died down, and we were treated to looks at a variety of raptors, as well as many other birds and mammals.

Raptors

Bald Eagle – 4 (All juveniles or subadults)

Golden Eagle – 9

Northern Harrier – 2

Red-tailed Hawk – 1

Ferruginous Hawk – 6 (including one that caught a rodent after we inadvertently flushed it)

Rough-legged Hawk – 11 (mainly adult females; no adult males).

American Kestrel – 1 (a male with a vole)

Great Horned Owl – 1

Non-raptors

Eared Grebe

American Wigeon

Mallard

Northern Shoveler

Canvasback

Redhead

Lesser Scaup

Bufflehead

American Coot

Black-billed Magpie

Common Raven

Black-capped Chickadee

Western Meadowlark

We had a great look at a pronghorn herd that bunched together and ran when an adult Golden Eagle flew toward it. We also saw another large herd of running pronghorns. Other mammals included a small group of mule deer, a white-tailed deer, and a little red fox poking its head over a nearby hill. Thanks to all who participated!
