I heard that there are falcons that nest on the City's main library building. Where can I get more information about them?

Peregrine falcons have been nesting at the library since 2004. They occupy the nest (scrape) from March until June each year. There is an Evanston Peregrine Falcon Watch group for posting and sharing news and observations of the Evanston Peregrine Falcons.  Scientists from the Field Museum’s Chicago Peregrine Program band the young falcons each year.
