Subject: [wisb] mIlwaukee redtail with large orange circle tag?
I received a call from Dave Piasecki with a question. I’d like to know too.
There is a Red-tailed Hawk just north of the I-94 Park-and-ride 6th and Holt.
It is perched on what might be a cell tower 30 to 40 feet up.
It has a large 6 inch circular orange something on its back with the numbers
363. The sign is large enough that one might think it impedes the hawks
flight. Don’t know. Does anyone know of a study with these tags?
Dave is going to check on its health tomorrow. Definitely makes it easy to
identify. There is a known nest site nearby that you can see from the
expressway at the plainfield curve, never saw this bird there.
