The Great Backyard Bird Count, an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent, is coming up.

This year’s version of the Great Backyard Bird Count will take place Friday, Feb. 17, through Monday, Feb. 20.

Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes on one day, or you can count for as long as you like each day of the event. www.birdsource.org/gbbc.
