I watched it circle a few times in the dark sky then head to the east side of the plant. I quickly jumped in the car and drove over to the Wyandotte Hospital parking lot just north of the power plant, and scanned the stacks for the bird. A second Peregrine flew in and landed on one of the roofs next to the first bird. Since I had my scope I pulled it out and watched both birds for about 10 minutes before heading off to work. Great start to a Friday morning, and it was only 6:30 am!
Both birds then took off and circled over the hospital before disappearing to the south.
The bird I was scoping appears to be perched next to the box.
With skies threatening I packed up and headed for home. Hopefully w/ some clear skies I'll get better looks at these beauties!
