Status of Listed Species and Recovery Plan Development

Peregrine Falcon

Falco peregrinus -- Endangered

Wisconsin

Current Status:

Current trends indicate that the recovery goal of 20-25 breeding pairs in the Great Lakes Recovery Region may be reached in the next decade. Although there is concern that environmental contaminants could cause decreases in reproduction and increases in mortality, there is little evidence that such problems exist now. Predation on nestlings, fledglings, and adult falcons by great horned owls and raccoons has been significant at some historic eyries, making them unsuitable as hacking sites.

Achievements:

Fifteen peregrine falcons were hacked in Wisconsin in 1991, and 41 were hacked in 1992. The State is considering ending its hacking program after 1993 because of the growing population of peregrines in the wild. One successful nesting occurred in Wisconsin in 1991, fledging four peregrines. In 1992, three successful nests fledged eight peregrines.

Current Recovery Needs:

The peregrine falcon will need continued monitoring to detect any problems with contaminants, predation, and low genetic variability. Additionally, individual peregrines and their nest sites will need continued protection.

Partnerships

Wisconsin Department of Natural Resources: This State agency has taken the lead in organizing and funding peregrine hacking and monitoring activities in Wisconsin.

The Raptor Center at the University of Minnesota, St. Paul Campus: The Raptor Center has coordinated peregrine falcon reintroduction efforts in Wisconsin and throughout the Midwest. All peregrines for Wisconsin hacking programs are obtained by The Raptor Center; examined and treated by its veterinarians; and banded, released, and monitored by its staff and volunteers.

Recovery Plan Status:

Original plan approved 8/20/79; revised 9/27/91.
