Forty-two volunteers counted more than 1,400 chimney swifts at dozens of locations throughout Green Bay for the third annual Swift Night Out on Aug. 10.
The nationwide event is intended to count and document chimney swifts, a federally protected bird on great decline because of fewer open chimneys. The birds, which don't perch, spend all day flying and then drop into chimneys at sunset to roost.
Local volunteers counted 483 swifts going into the chimney at Aldo Leopold Community School - the highest number of the night.
"We had a great increase in numbers overall this year - more volunteers, more swifts documented and a greater amount of locations monitored,'' said Nancy Nabak, who co-chairs the local event with Jim Johnson.
Swift Night Out draws attention to the species with a goal of keeping it a commonly seen bird in Wisconsin, she said.
