On Janurary 18th, I was lucky to see what looked like the aftermath of a Red-tailed Hawk successfully preying on a pigeon. By the time I arrived, the hawk seemed to have finished consuming its pigeon prey. There was snow the night before, so locating the plucked pigeon feathers was difficult, but I tried and took a few photos.

I happened to carried a mini monocular in my pants pocket that day, so I was able to have a decent shot of the Hawk's body details.

I stayed at the scene for a couple more minutes, fascinated by an individual of a species the supposedly belongs to the wild, and I tried to gauge the extent of the mess it made. It took off and settled in a tree right next to the library driveway. The hawk in fact roosted at the very same spot for one full hour at least, between 10:00AM and 11:10AM, possibly being too full to maneuver.

The photo below was taken at 10:25AM, while the red-tail was roosting in the tree right next to the library driveway.

Later that day, the snow melted, and I was able to see the full extent of the scattered pigeon feathers, and I found white bird droppings right below the canopy of the tree where the red-tail relocated to and roosted in. Of course, the hawk had been gone by that point.

The droppings:

I saw what was likely the same hawk perching in an oak tree not too far from the library. This time, I didn't find anything that suggested any act of predation had taken place.
