ITHACA (AP) -- The Great Backyard Bird Count, a citizen's science project conducted across North America for four days each February, is expanding globally this year.
Anyone in the world with Internet access can participate in the 16th annual count Feb. 15-18. Participants watch birds at any location for at least 15 minutes, tally the numbers of each species, and report online at www.BirdCount.org .
The count is a joint project of the Cornell Lab of Ornithology and Audubon, with partner Bird Studies Canada.
Global participation is made possible by eBird, a real-time online checklist that the Ithaca-based Cornell Lab and Audubon are integrating into count for the first time.
Participants will be able to upload their counts from the field using the eBird BirdLog app for Apple or Android smartphones.
