Peregrine Falcon 2010 information and webcam
Peregrine Falcons have been present on the UWM campus for several years frequently seen soaring above or perched on several of the high rise buildings on campus. In particular, much activity has been observed on the Engineering & Mathematical Sciences Building. In the fall of 2007, Greg Septon of the Peregrine Falcon Recovery Program, toured the EMS site and encouraged University officials and scientists to build and install a nest box at the site. Plans were drawn up for the box, UWM Physical Plant carpenters and other trades workers constructed and installed the nest box at a site chosen on the roof of the EMS building. Department Biological Sciences faculty and staff provide scientific observation and data reporting. Thomas Hansen from the WATER Institute, Monica Cloutier from UTIS and Thomas Schuck from Biological Sciences helped construct and maintain this web site. Please see the UWM homepage News Story for additional photos and information.

Season Summary: An adult male "Hoffmann" (b/g) 54/M, replaced last season's male "Samson" (b/g) E/43 who was found injured in Houston, TX with a broken wing. Hoffmann paired with an unbanded female, believed to be the same female as last year. 4 eggs were produced between March 29 and April 5 and hatched between May 5 and 7. 2 female and 2 male chicks were banded on June 1. All chicks fledged.
