Citizen Science Projects

COLONIAL WATERBIRDS: If you enjoy watching the annual nesting, breeding and fledging of Colorado's large wading and diving waterbirds, consider joining DFO's Colonial Waterbirds Project. Volunteers regularly visit nesting sites for Double-crested Cormorants, Snowy Egrets and Great Blue and Black-crowned Night-herons in several Denver-area parks. Between early spring and late summer, they count bird and nest numbers, observe and record courtship, mating and nest-building behavior, and document the hatching, rearing and fledging of young at these communal nesting sites. Click the "Colonial Waterbirds" link to learn more. Read the "How To" file first, then read the "Locations" file.

VIREO AND NUTHATCH STUDY: Another project in which DFO members have cooperated is work by Garth Spellman, ornithologist for the Denver Museum of Nature & Science, to investigate the boundaries in Colorado between subspecies of both Warbling Vireo and White-breasted Nuthatch. Click the "Vireo-Nuthatch" link to learn more. You can also quiz yourself with snips of audio recordings of the different subspecies of these two birds.

ROSY-FINCH MOVEMENT DATA: Another research project by Spellman seeks to track the summer and winter distribution of Brown-capped Rosy-finches. Spellman's group seeks DFO birders' help in looking for birds of this species that have been banded by bird scientists. Those who spot Brown-capped Rosy-finches wearing leg bands are asked to record date/time, location, bird numbers and other vital data. Click the "Rosy-Finches" link for more details.
