Since 2005, Peregrines have been most often seen in an area roughly bounded by Ford Road and Michigan Avenue, the Southfield Freeway and Mercury Drive (outlined in red on the map below, or in the vicinity of this marker).

Getting a close look at a Peregrine is not easy. For example, the one that spent last winter in Dearborn on the Village Plaza building at Michigan and Outer Drive usually sat on a blind ledge, high up on the building. But the Fairlane Plaza birds often perch on the office window ledges. In 2007, I got this photo third-hand of an office-peeper:



These photos are frustrating, because the legs of the falcon are not readily visible. Many of the Peregrines in the region are banded with a unique combination of color bands that allow identification of individual birds. Beginning in the late 1970s, a large, cooperative effort to help this species recover from population declines due to DDT was launched. Hundreds of Peregrines were released in the Midwest, and the species is still intensively monitored. The Midwest Peregrine Society brings together many resources in the region.
After letting the Ford people know what to look for, and encouraging them to get a good photo of the legs of any Peregrine stopping by, I got this great shot:

Please meet Ember, a female Peregrine hatched in April 2010 in a nest box on a smokestack at the Louisville Gas and Electric (LG&E) Mill Creek Generating Station, a coal-fired power plant along the Ohio River just south of Louisville, Kentucky! This location is about 320 miles away from Dearborn.
Ember is the offspring of one of only about a dozen pairs of nesting Peregrines in Kentucky. LG&E has Peregrine nesting sites at several of their facilities as part of their environmental initiative. The Mill Creek nest box was put up in 2006, and began being used the following year. Ember's mother was unbanded (as was the female each year at the site). Her father may be banded, but this is unconfirmed. Ember has three siblings: males named Volt and Dakota, and a female named Phoenix.
Ember left her nest on 19 May 2010. The photo above was taken in late July. Ford people have reported seeing her (and her bands) as recently as a week or so ago. As far as I have been able to determine so far, these are the first reports of the whereabouts of Ember since she left the nest site.
The Ford folks also think there has been another bird present at times. And since Ember is a youngster, she is obviously not the bird that wintered in previous years. I think everyone is motivated to get a good look at the legs of any falcon that visits at their windowsill now, and if we confirm any additional birds, I'll post an update.
Many thanks to Tim Endlein, Liz Saeger, and others at Ford; Mike O'Leary of the Dearborn Police Department; Chris Becher and Barb Baldinger, Peregrine monitors for the Michigan Department of Natural Resources and Environment; and all the others who regularly report Peregrine sightings to me.
