Denizens of the Alpine: Breeding Site Selection and Winter Movements of Brown-capped Rosy-Finches

"Denizens of the Alpine: Breeding Site Selection and Winter Movements of Brown-capped Rosy-Finches"
Amy Seglund, Colorado Parks & Wildlife and Aaron Yappert, Wildlife Biologist

The highest elevations in Colorado make for a harsh environment in which to survive. Yet a small, but hardy passerine, the Brown-capped Rosy-Finch — considered a "species of greatest conservation need" by Colorado Parks and Wildlife — lives year-round in Colorado's high country. Come learn about this little-studied bird and the efforts currently underway to evaluate its population status and breeding ecology. 

Amy Seglund is a seasoned wildlife biologist that has worked in a variety of ecosystems. Since 2011, she has studied alpine species including the white-tailed ptarmigan, American pika and most recently the Brown-capped Rosy-Finch.

Aaron Yappert is a wildlife biologist with an passion for birds and conserving wild spaces. He has spent the last few years studying avian behavior in the field and been a part of the Rosy-Finch Project since 2017.
