Thanks Barb and Janet. Sounds like the fixings for some good hearty broth just laying around up there! Yuk.

In the 13 years that I helped the MDNR to monitor the Peregrine Falcons in Mount Clemens, I made several trips to the rooftops of both the Macomb County Building and the Administration Building across the street. I never saw more than one or two remnants of prey items on the rooftops. The corners of the Macomb County Building have more leftovers. The Peregrines also favor the court house ledges, above the tall windows. As Janet Hinshaw said, Turkey Vultures sometimes clean up the leftovers. There are often Turkey Vultures peacefully coexisting on the Administration Building.

The peregrines usually have several favorite sites where they take and eat their prey. They often remove feathers, wings and heads, sometimes feet before they eat the rest. They will swallow bones and can eat the smaller birds whole. But yes, there are a lot of leftovers on the roofs. Sometimes turkey vultures will clean them up.

I regularly see Peregrines in downtown Mt. Clemens. While I understand their need to return prey to the nesting sites on rooftops while chicks are growing, do they return ALL kills to the nest site for the rest of the year to dine on their own even though the kids have gone? The reason I ask is...what do the rooftops look like? I figure that perhaps with one Pigeon per day, the carnage must start to pile up after a while. Do building maintenance people have to remove the remains of hundreds and hundreds of bird skeletons every year after the soft parts are eaten and the feathers blow away?
