Bird Watchers Prepare for Annual Backyard Tally

ITHACA, N.Y. -

Organizers of the 17th annual Great Backyard Bird Count say they expect bird watchers from more than 100 countries to participate in this year’s event, Feb. 14-17. Anyone in the world can participate by counting birds for at least 15 minutes on one or more days of the count and recording sightings. Data from North American participants will help define the magnitude of the southern influx of snowy owls this winter. Observations may also help show whether American crows are continuing to rebound after being hit hard by West Nile virus. The count went global for the first time last year.
