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.

Sweet song of the Prairie Skylark

By | Monitoring Programs | No Comments

The Sprague’s Pipit is a charismatic songbird of North American grasslands. If you’ve ever wandered the Northern Great Plains in summer, you’ve probably heard their sweet song, and maybe even seen their high-altitude aerial displays which can last for hours. One of many fast-declining grassland bird species, we’re urgently working to learn more about the life cycle of the Sprague’s Pipit so that its song can continue to be enjoyed for generations to come.

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.
