Peregrine Falcons

By the 1960’s the Peregrine Falcon had become an endangered species due to the widespread use of DDT which was later banned in the 1970’s.  Efforts to repopulate the Peregrine have included the introduction of birds raised in captivity to urban landscapes where tall buildings, close proximity to water, and sources of pigeons and starlings for food approximate the bird’s preferred natural habitat.

In the fall of 2011, workers from Veolia Water Milwaukee built a nesting box and installed it on the roof of the Milorganite building at the Jones Island Water Reclamation Facility.  The box – which includes a hinged door to facilitate banding of the birds - attracted a nesting pair of Peregrines in spring of 2012.  Three young peregrines hatched, grew, and learned to fly from their perches 150 feet above ground.  In 2013 and 2014, a pair once again nested in the box and successfully raised two chicks each year.
