The 21st Great Backyard Bird Count begins Friday, Feb. 16, and the Three Rivers Audubon Society invites the community to participate.

The county is an annual citizen-science project that gathers data worldwide to create a real-time snapshot of the bird population, according to a news release. This information is used by scientists at the Cornell Lab of Ornithology. Their free app, Merlin, will help with identification.

To participate in the Great Backyard Bird Count, participants should record the birds seen in an at least 15 minute intervals from Feb. 16–19 and report what is seen at or to Delos McCauley at 850-7861.
