Come hear about RMBO's Colony Watch - Wed April 24th at 7 pm

The Laramie Audubon monthly meeting will be held this Wednesday, April 24th. This month we will be hearing about colonial waterbirds from Chuck Hundertmark with the Rocky Mountain Bird Observatory.

Meeting Schedule:
6:30 pm - Bird Chat and refreshments
7:00 pm - Update on Mortenson Lake and Hutton Lake National Wildlife Refuges Expansion Project
7:15 pm - Colonial Waterbirds of North Park: Preliminary Results of a Rocky Mountain Bird Observatory Citizen Science Project by Charles A. Hundertmark, Rocky Mountain Bird Observatory.




Program Description:
From 1998 through 2012, biologists and volunteers from Rocky Mountain Bird Observatory (RMBO) monitored breeding populations of 12 species of colonial waterbirds as well as Osprey, Bald Eagle, and Willet in North Park. The colonial waterbird species predominantly nest on or near the numerous reservoirs and ponds of this north-central Colorado mountain park.

This monitoring, conducted through Project Colony Watch, was initiated as an integral part of the comprehensive Monitoring Colorado’s Birds program. After 15 years, a picture is emerging of dynamic population fluctuations that respond to sometimes abrupt or dramatic changes in water levels. While populations of some species (e.g., Eared Grebe, American White Pelican, California Gull) appear to be stable, others (e.g., Franklin’s Gull, Black and Forster’s Tern) endure at marginally viable levels. This presentation will discuss colony locations, changes in colony size and location, and movement of species among colonies.

Location:
Our meetings are held on the University of Wyoming campus in the Berry Biodiversity Center located at the corner of 10th & Lewis Streets. There is free parking after 5pm. Laramie Audubon Society programs are free and open to all public.

White-faced Ibises

Liz Young is a long-time member of National Audubon Society and recently moved to the Laramie area.  She lives in the mountains near Vedauwoo at about 8700 feet above sea level.  This morning during the snow storm, she spotted three White-faced Ibis in her yard.  Here are some pictures of the wayward visitors to her yard. 

Plains Lakes Trip Report

Nesting Great Horned Owl

After a week of cold and snow, the sun finally emerged for Laramie Audubon’s Plains Lakes field trip, and the birds were equally cooperative. Waterfowl and raptors predominated. Large numbers of ducks fed, loafed, and engaged in early courtship displays on Osterman Lake, Meeboer Lake, Gelatt Lake, and Twin Buttes Lakes. (We did not have time to visit Lake Hattie or Woods Landing). American White Pelicans showed off their breeding season bill horns while American Avocets swept their elegant bills through the shallow water. A beautiful cream-colored Great Horned Owl peered at the assembled birders from her nest as did a more nervous incubating Red-tailed Hawk. We were delighted to see a late-season male Rough-legged Hawk and some of us were fortunate enough to see a female Merlin. A male McCown’s Longspur perched in the gravel in front of our car by Meeboer Lake and regaled us with his beautiful song. A possible Greater Scaup and a Clark’s Grebe garnered lots of attention and some debate. But the bird that stole the show and made everybody’s day was an achingly beautiful Peregrine Falcon that treated us to lengthy close-up views. She seemed unconcerned by our presence as she stretched her wings and legs, and gazed out over the snowy landscape. She lingered on her fencepost perch long after we’d moved on in search of other birds. And she lingers still in the minds of those fortunate few who had a chance to fill their binoculars and scopes with her elegant image during our field trip. We saw 44 species in total and enjoyed ourselves immensely. Come and join us for the next one: Arapaho National Wildlife Refuge (in Colorado) on May 4, 2013.

Poaching Around Laramie

We have received reports of poaching around Laramie, both at the Plains Lakes and Hutton National Wildlife Refuge. It is illegal to hunt within the refuge and it is illegal to hunt migratory birds (Migratory Bird Treaty Act). If you encounter poaching, please protect yourself and then contact officials. You may be given a reward if an arrest and citation are made. 

The "STOP POACHING" Hotline phone number is 1-877-WGFDTIP (1-877-943-3847) or 1-307-777-4330 for out-of-state "STOP POACHING" calls only. Here's a link to their website: http://wgfd.wyo.gov/web2011/wildlife-1000335.aspx 

Alternatively, you can call the local police at 911.

Field Trip to Plains Lakes/Woods Landing, April 20

Tomorrow Sophie Osborn and Catherine Symchych will lead a Laramie Audubon field trip to the Plains Lakes and Woods Landing. The lakes and plains could be filled with migrants and passers-through, while eagles and other raptors cruise the skies. Depending on conditions, we will head to Osterman pond, Meebor, Gelatt, and Twin Buttes, and then Woods Landing to see what's hanging around the river and mountains. Call 307-721-9841 (Catherine) or 307-760-8546 (Sophie) for more information.

Meet at Coal Creek Coffee at 8 am, 110 E. Grand Ave., downtown Laramie to caffeinate and carpool.

Field Trips are free and open to all levels of birders. You may drive your own car or ride with someone else. Bring binoculars, scope (if you have one), field guide(s), snacks and water. Dress for the worst weather and then add a layer. Families are welcome. Be sure to gas up ahead of time. Field trips may last for several hours. You may return to Laramie at any time if you have your own transportation.

***Please note that the trip to the local Sage-Grouse lek has been CANCELED for this weekend and is now scheduled for Saturday, April 27th.***

Sage Grouse Trip CANCELED

**UPDATE** The field trip on Saturday, April 12 to the Greater Sage Grouse Lek has been CANCELED due to impassable road conditions to the lek.

The field trip has been rescheduled for Saturday, April 20.  Further updates will be posted to the website as the new trip date approaches.

Weekend Trip to Local Sage-Grouse Lek

Saturday morning, April 13th at 5:00 am. Come watch the grouse strut their stuff!

Meet at 5am at the Eppson Senior Center parking lot, Curtis & 3rd St., Laramie.  We will carpool to the lek at 5:10am sharp.  Please call 516-376-4587 (Shawn) or 307-760-9518 (Vicki) if you plan on attending so we will have an idea about how many people to expect.  4WD recommended.  Carpooling encouraged.  It is very windy at the lek so dress extra warm.  We are usually back in Laramie by 8 or 8:30 am. 

Alternate date in case of inclement weather or impassable roads is April 20, same time and place. If that day is bad, then we will try April 27, 4:30 am, leaving at 4:45 am sharp.

Dress for the worst weather.  Bring snacks and water, hot beverage optional, binoculars, scope if you have one, and field guides.  You may return to Laramie at any time if you have your own transportation.  Families are welcome.  We stay close to our automobiles so as not to disturb the grouse.  Be sure to gas up ahead of time! 

Spring has Sprung in Laramie

Over the past week, birds have started showing up to the Laramie area. On the Plains Lakes, hundreds of Redheads (Aythya americana), Lesser Scaup, and many other waterfowl are filling in the recently thawed ponds and lakes.

Along with waterfowl, gulls are also returning to the Laramie Plains, with California Gulls (Larus californicus) making up the bulk of the diversity. The star of the past weekend, however, was a young Iceland Gull (Larus glaucoides) that James Maley found at Sevenmile Lake. This sighting represents the first time that this species has ever been found in Wyoming!

Not to be outdone, on Monday, Don Jones discovered an adult Great Black-backed Gull (Larus marinus) on Meeboer Lakes, part of the Plains Lakes, which represents only the third time this species has been found in Wyoming.  Associating with the Great Black-backed Gull was also a Lesser Black-backed Gull (Larus fuscus), a rare visitor from Europe.

NY Times: Winter of the Monarch

The New York Times ran an interesting, albeit disturbing, piece on the threats to the wintering range of the monarch butterfly. The piece came out last week, but with spring in the air (gulls and blackbirds have returned!) I thought others may be interested.

Bright nights speed birds' lives

Exposure to low levels of artificial light at night can cause birds to become ready for reproduction earlier than those that experience dark nights.

Davide Dominoni and his colleagues at the Max Planck Institute for Ornithology in Radolfzell, Germany, attached miniature devices to wild European blackbirds (Turdus merula) to record the light levels that the birds experience in city and forest environments. On the basis of these data, the authors exposed adult male blackbirds captured from both settings to either dark or low-light conditions at night. Birds kept in the brighter-night environment developed reproductive physiology nearly a month earlier and moulted sooner than their dark-dwelling counterparts.
The light level the authors used was 20 times lower than that produced by a streetlight, showing that even small changes can have an impact on animal development.

Winter Finch Extravaganza!

Across southern Canada and much of the United States, a variety of winter finch species have irrupted south of their typical winter range to the delight of many birders. While this pattern is most pronounced in the east, with huge numbers of both Red (Loxia curvirostra) and White-winged Crossbills (Loxia leucoptera), as well as Common (Acanthis flammea) and Hoary Redpolls (Acanthis hornemanni), we here in Laramie are also seeing good numbers of Red Crossbills and Common Redpolls, which are usually very rare in southern Wyoming. In addition to the winter finches, irruptions such as these also see large flights of Red-breasted Nuthatches (Sitta canadensis) and Bohemian Waxwings (Bombycilla garrulus), both of which are showing up in parts of Wyoming.

While finch irruptions are fairly typical on a cyclical basis, the one that birders are seeing this winter is unusually large, due to widespread seed crop failure, including those of various coniferous trees, birches (Betula), alders (Alnus), and Mountain Ash (Sorbus sp) (Erskine and McManus 2003, Howe et al. 2012). As finches in the north wander in search of good seed crops, they move southwards in huge numbers (Pittaway 1998).

In addition to the irruptive species that only visit Wyoming on occasion, winters in Wyoming also host a number of other great finch species, including Pine Grosbeaks (Pinicola enucleator), Evening Grosbeaks (Coccothraustes vespertinus), and all three rosy-finch species (Leucosticte sp). Recently around Laramie, we have seen good numbers of Gray-crowned Rosy-finches (Leucosticte tephrocotis) and Red Crossbills, as well as smaller numbers of Pine Grosbeaks and Common Redpolls. 

Gray-crowned Rosy-Finch (Leucosticte tephrocotis) - Buford, WY

Pine Grosbeak (Pinicola enucleator) - Albany, WY

Common Redpoll (Acanthis flammea) - Albany, WY

As winter turns slowly into spring here in Wyoming, we can expect to continue to see many of these irruptive species well into April before heading back northward.

For more information on patterns of winter finch irruptions, see this very informative and interesting write up on eBird by Ron Pittaway.

7:00 pm: Sage-grouse as an umbrella species: is what’s good for the goose really good for the gander? – Jason Carlisle
Is Greater Sage-Grouse conservation beneficial for other inhabitants of the sagebrush steppe? The ecological concept known as the “umbrella species concept” holds promise as a means of streamlining the efforts of resource-strapped wildlife managers and extending conservation to oft-overlooked parts of the wildlife community such as non-game birds, small mammals, reptiles, and beyond. Simply stated, by focusing conservation efforts on a suitable umbrella species, managers hope to also benefit co-occurring wildlife with similar ecological requirements. Although the Greater Sage-Grouse has been informally adopted as the umbrella species of the iconic sagebrush steppe, this idea remains largely untested. Come learn how researchers from the WY Cooperative Fish & Wildlife Research Unit are setting out to test this idea using time-tested field methods and cutting-edge spatial analyses and how you can help.

Jason Carlisle, UW PhD student in Program in Ecology and Wyoming Cooperative Fish and Wildlife Research Unit.

As usual, the talk will be held in the auditorium of the Berry Center, room 138.
