Grassland Birds of the Trans-Pecos

By | Monitoring Programs, Science | No Comments

Grassland bird populations are declining and the majority of species are understudied on their wintering grounds. In the winter of 2020, we implemented a regional monitoring program in the Chihuahuan Desert of Texas to establish baseline population estimates of grassland birds. We surveyed on a number of expansive cattle ranches, each exhibiting fascinating ecological and management histories. Through the implementation of this program, we can share that collaboration between ranching operations and grassland bird conservation is mutually beneficial.

Decoding Bald Eagle Migration

By | Science | No Comments

Around 200 pairs of Bald Eagles call Colorado home, with most breeding pairs remaining in the state year-round, rearing their young here in the spring and summer. Why, then, does Colorado’s Bald Eagle population surge to well over 1000 birds in the late fall and winter? Migration is the obvious answer, but as you might suspect, it’s a bit more complicated than that. Why do some eagles migrate while others do not? Here we’ll explore the answer to that question and more.

Birds in Crisis

By | Monitoring Programs, Science | No Comments

Since 1970, less than a single lifetime, North America has lost more than one in four of its birds, according to a report in the world’s leading scientific journal. New findings just published in the journal Science confirm staggering losses among birds. Based on nearly 50 years of data, this research for the first time quantifies a long-developing but overlooked ecological crisis.

Private Lands, Public Birds

By | IMBCR, Science, Stewardship | No Comments

For over ten years, private landowners have been granting permission for Bird Conservancy to conduct bird surveys on their land. These partners in conservation enable us to learn about bird populations across the whole landscape, beyond public lands. Equally important are the lasting friendships that often form between our staff and the landowners as they bond over birds, landscapes and the stewardship values we share.

Big Year for Banding at Barr Lake

By | Education, Science | No Comments

Barr Lake’s fall banding station had an incredible season with 1,902 individual birds caught last year—more than any year in over a decade! The station celebrates another chapter of educating visitors of all ages about the importance of birds in our lives, while also contributing to our understanding of bird distribution, population levels, and conservation needs at key migration stopover habitat.
