The falcon chicks are expected to fledge (make their first flights) by the end of June. Occasionally, a fledging will run into difficulties and end up stranded on the ground.

Should you spot a fledging on the ground, please immediately contact Thomas Schuck at 414- 750-4648.

2009 in Review: New UWM family members
Five falcons at UWM The adult male with the four young falcons born during commencement weekend. NEW: Watch the chicks being banded (YouTube video)

As UWM was saying farewell to hundreds of grads, four new members of the UWM family appeared on campus.

Beginning on May 16, four peregrine falcon eggs began to hatch on a ledge on the south face of the UWM Engineering and Mechanical Sciences building (EMS).

Greg Septon, a peregrine falcon manager and researcher, worked with UWM to build a nest box "on speculation" over a year ago, when falcons were observed near campus. Thomas Schuck, a laboratory manager in the Department of Biological Sciences, has been operating a webcam and recording visiting falcons' behavior since April 2008. A nesting pair occupied the box this year and have now made it a home for themselves and their hatchlings.

The mother laid her first egg on April 8, with the other three following within a few days.

The nest makes UWM part of a successful effort to restore the falcon to Wisconsin.

Septon points out that the peregrine falcon was declared extinct east of the Mississippi River in 1964, but a recovery program, begun in 1987, has had remarkable success. Statewide in 2008, there were 27 nesting pairs and 81 young hatched. Locally, there are seven known sites that have produced young.

Septon and Schuck visited the box on June 8 to band the birds and name them. Septon believes there are three females and a male, though there may be a second, unusually large male. (Females peregrines are typically a third larger than males.) YouTube video of banding.

The falcons feed on small birds and the occasional pigeon. The parents can be seen on the webcam feeding their young.

The EMS webcam site has real-time images as well as time-lapse compilations. A separate page on the Biological Sciences website has background information on the nest and peregrine falcons, as well as a running selection of some of the best images of the young falcon family.

Schuck notes that the project was made possible by the cooperation of a wide array of campus units, including electricians, carpenters, UITS, even the WATER Institute.

He recommends that people restrict their interactions with the falcons to the webcam, since any physical disturbances could lead the birds to abandon their nest – and their young.
