Powder Valley Nature Center invites the public to participate in the large-scale citizen science event, The Great Backyard Bird Count, by counting bird numbers and species.

On Friday, Feb. 15, from 9 a.m. to noon, at the nature center, learn what the bird count is and how citizens can participate at home. The class will also go out and count birds at the center’s feeders and/or trails.

This is a good opportunity for the public to enjoy birds in their own backyard while providing scientific data.

Register for the program by Feb. 13 by calling 314-301-1500.

Powder Valley is located at 11715 Cragwold Road in Kirkwood.
