DOWNTOWN — There are more of the world’s fastest-flying birds zipping around Chicago after another successful peregrine falcon breeding season within city limits.

The Chicago Peregrine Program found 13 nesting locations in the city, where at least nine of the nests having successfully hatched fledgling young, according to Josh Engel, a researcher at Field Museum who’s part of the peregrine program. Engel estimated about 25 new birds in Chicago this year.

Neighborhood nests include ones in South Loop, UIC, Millennium Park and Belmont-Addison in Lakeview, and on Chicago’s “cribs,” the four, man-made water-intake islands two miles out in Lake Michigan. Engel said researchers found one new peregrine nest this year Downtown, a few hundred yards from another nest.
