EVANSTON (WBBM NEWSRADIO) — For 17 years, a pair of peregrine falcons has been nesting in the upper reaches of the Evanston Public Library.

Every year, scientists place bands on the chicks' legs, a procedure that usually draws a crowd. Not this year, because of social-distancing requirements. 

This month, four falcon chicks were born on a ledge of the Evanston library, and on June 6 they'll all be around three weeks old.

"What we can do is bring them in and put bands on the legs. And those bands are unique to the individual. It can tell us things like longevity and dispersal,” explains Mary Hennen, assistant collections manager in the birds division at the Field Museum.

She’ll be doing the banding and continues to track peregrine falcons that have been banded in the past. The Cubs fan named one of the birds after player Ron Santo. 

“That bird Santo ended up all the way down in Ecuador,” she said.

Hennen says the June 6 banding — and naming of the chicks — will be online starting at 10 a.m.

People are invited to submit suggestions.
