On two days that I was home and observing from my summer office window in June – I noticed two squirrels that looked like they had survived a predator. The first one sprawled on the deck railing long enough for me to realize some fur on top of it head/neck was missing, and the fur looked matted.
I zoomed in. It looked like the injury might be healing already.
A few days later, another squirrel was on the deck (or I think it was another one) with a much larger area of missing fur that looked infected. There was also a wound near its nose.
There seem to have more than our usual number of squirrels this year. Did a juvenile hawk decide the area was easy pickings for a meal but was not adept enough to get its prey? At least twice?
