Re: [cobirds] Citizen science effort to document Brewer's Sparrows in alpine willow/krummholz

Fellow Colorado Birders,

We encourage you to respond favorably to Dr. Walker's request for volunteer assistance monitoring breeding of Brewer's Sparrows at high altitude in Colorado. This is a perfect opportunity to use your observation skills for the understanding and conservation of Colorado birds. Thanks to birders like you, eBird has shown that citizen science can have great impact in ornithology. For that reason, Colorado Field Ornithologists is looking for ways like this project to harness the skills of members and supporters to promote conservation of Colorado birds and their habitats.

Colorado birders,

If you're looking for another reason to visit the high country this summer, CPW needs help from birders to document the statewide breeding distribution of Brewer's Sparrows in alpine willow/krummholz habitats near treeline from now through July 31! 

Brewer's Sparrows (Spizella breweri) are normally considered a sagebrush obligate during the breeding season, but thanks to the efforts of Colorado birders (esp. eBirders!), Bird Conservancy of the Rockies, and USFS biologists over the years, we now know that Brewer's Sparrows also breed in alpine willow/spruce-fir krummholz at alpine and subalpine sites (~10,000-13,000 ft) scattered across the state in June-July. But CPW and the USFS need additional information on their statewide breeding distribution and abundance in alpine areas before updating conservation assessments for the species.

CPW has identified 31 priority sites on USFS public land for birders to search for them across the state. Nearly half the sites are accessible by road. To learn more, including where to find them, how to identify them, and how to submit your observations, see:

Thanks,
