Take part in Great Backyard Bird Count

Residents can take part in the global Great Backyard Bird Count at a special Forest Preserve District of DuPage County bird walk.

From 10 to 11:30 a.m. Sunday, Feb. 18, visitors can join a forest preserve ranger at Waterfall Glen Forest Preserve in Darien.

Together, the ranger and participants will look for different bird species and then record their sightings with the Cornell Lab of Ornithology and the National Audubon Society at birdcount.org. Last year, more than 214,000 participants submitted observations during the four-day event, creating the largest snapshot of global bird populations ever recorded.

Scientists use the data recorded during the bird count to inform research into changes in weather, climate and habitat; species population size and health; migration patterns and more.

The program is for all ages, but those younger than 18 should be accompanied by an adult. Register online at dupageforest.org or by calling (630) 933-7248.

Participants should meet at the waterfall parking lot on Bluff Road. Bring water, dress for the weather, and wear sturdy shoes for this moderately paced walk, which may go along uneven turf trails.
