Project FeederWatch is a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatchers periodically count the birds they see at their feeders from November through early April and send their counts to Project FeederWatch. FeederWatch data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance.

Anyone interested in birds can participate. FeederWatch is conducted by people of all skill levels and backgrounds, including children, families, individuals, classrooms, retired persons, youth groups, nature centers, and bird clubs. Participants watch their feeders as much or as little as they want over two consecutive days as often as every week (less often is fine). They count birds that appear in their count site because of something that they provided (plantings, food, or water).
New participants are sent a Research Kit with complete instructions for participating, as well as a bird identification poster and more. You provide the feeder(s) and seed. Then each fall participants receive our 16-page, year-end report, Winter Bird Highlights. Participants also receive the Cornell Lab newsletter.
There is a $18 annual participation fee for U.S. residents ($15 for Cornell Lab members). Canadians can participate by joining Bird Studies Canada for CAN$35. The participation fee covers materials, staff support, web design, data analysis, and the year-end report (Winter Bird Highlights). Project FeederWatch is supported almost entirely by participation fees. Without the support of our participants, this project wouldn’t be possible.
Project FeederWatch is operated by the Cornell Lab of Ornithology and Bird Studies Canada.
