“Birds of the Rocky Mountain Region” art exhibit at The Brinton Museum in partnership with the Bighorn Audubon Society, a juried exhibit with awards for the top four, will open on May 4, 2023, and continues through July 2, 2023.  Three outstanding jurors in their fields will select 40 pieces for exhibit. Invited jurors are Kenneth L. Schuster, Brinton Museum Director & Chief Curator; Award-winning artist Joel Ostlind from Big Horn (WY); and Peter G. Arnold, Board of Directors Audubon Rockies. A color-illustrated catalog including biographical information on participating artists as well as educational commentary about birds represented in the exhibit will accompany this show.

An educational lecture on conservation activist George Bird Grinnell (1849-1938), presented by nationally-known journalist John Taliaferro is scheduled for June 8. Taliaferro is the author of the highly regarded publication, “Grinnell, America’s Environmental Pioneer and His Restless Drive to Save the West”. Grinnell’s deep connection to birds, Sheridan County, and his relationship to the Northern Cheyenne People helped to preserve much of what are now public western lands.


A series of outdoor programs on birds and birding organized by Bighorn Audubon will be offered at The Brinton Museum during the time period of this exhibition. A reception for the artists, free and open to the public, takes place in conjunction with the opening of the show. A color-illustrated catalog will be published to accompany this event and will include biographical information on participating artists as well as educational commentary about birds represented in the exhibit.

MARCH 23rd at 5:30pm 

Presentation on Greater Sage-Grouse habitat needs and

survival threats in the Powder River Basin

By Chris Kirol, M.S., Ph.D. Post-Doctoral Wildlife Ecologist

(Introduction by Dr. Ariel Downing)

March 23rd at 5:30 pm Inner Circle, Sheridan Fulmer Library

Free event

Sponsored by the Bighorn Audubon Society



Greater Sage-grouse thrive in landscapes dominated by unfragmented sagebrush habitat. However, largely due to human actions, large tracks of unfragmented sagebrush habitat are becoming much less common in the western U.S. and Sage-grouse population declines have mirrored this loss and fragmentation of sagebrush habitat over the last several decades. Population declines have been particularly stark in the Powder River Basin in northeastern Wyoming. In this presentation, Dr. Chris Kirol will be discussing the ecology of this unique bird along with sharing some interesting facts and details. He will also be sharing what he and his colleagues have learned through their research on Sage-grouse living in an industrial landscape in northeastern Wyoming. During the last five years, they have used female Sage-grouse fitted with GPS-transmitters to gather detailed information on habitat needs and Sage-grouse responses to disturbances, infrastructure and reclamation. Finally, and most importantly, he will describe actions we can take to improve habitat quality for Sage-grouse and ways to maintain and enhance areas of high reproductive potential to boost populations of this amazing bird.



Dr. Chris Kirol has been doing wildlife work in Wyoming for almost 20 years. Prior to obtaining graduate degrees in wildlife ecology at the University of Wyoming (Masters of Science) and the University of Waterloo (Doctor of Philosophy), he worked for an environmental consultant as a wildlife biologist where his primary duties involved conducting wildlife clearance surveys for industrial development. It was during this time that he became passionate about conservation of wildlife species that are dependent on the sagebrush ecosystem such as the Greater Sage-grouse. During his graduate work, he completed a master’s project studying Sage-grouse population fitness in an area that was undergoing oil and gas development. His master thesis was named Outstanding Masters of Science Thesis of 2013 by the University of Wyoming. Through his PhD and post-doctoral research, he has been working to apply field-based science to wildlife conservation issues in the sagebrush ecosystem. His research has primarily focused on bird species dependent of sagebrush ecosystems from sage-grouse to songbirds like the Brewer’s Sparrow. Broadly, his research explores how habitat quality—the ability of the environment to provide conditions suitable for individual and population persistence—can be compromised by human features and activities, and steps that can be taken to reduce the impacts of these activities on endemic species. Over the course of his career, his research has focused on applied science including critical habitat mapping, measuring the effectiveness of mitigation and assessing bird responses to reclamation. His research can be found in peer-reviewed journals such as Ecological Applications, Avian Conservation Ecology, and the Journal of Wildlife Management.
