A hawk at the bird bath!
I think it was a Cooper’s Hawk….when I opened up the front door to check him out he was eyeing up a grey squirrel on the bird feeder. I think the squirrel might have been able to take him.

The bane of song birds. Not unusual for them to be attracted by bird baths. They hang around our birdfeeders on occasion during the Winter. Once, I saw two gray squirrels attack one and drive it off. As it flew away, I could faintly hear it say..."Cheeky squirrels. If you were a bit smaller, I'd eat you both."

The squirrel apparently got up on the bird feeder right in front of the hawk!
These photos are from a battery powered camera I have mounted on the porch rail. According to the time stamp the hawk was there for at least 2 minutes…you can see the squirrel’s tail behind the feeder roof to the right of the frame.
of my house a few days ago. Looked out to see a hawk fly up to perch on the roof of my covered porch. It flew away before I could grab my camera or phone . But, some time later I noticed a squirrel hiding under the patio furniture on the covered porch! It was probably getting over the shock of being hunted by the hawk. Squirrels are attracted to the seed I put out for the birds and it wasn't the first time I've seen a hawk in my yard. This shot is from the last time a hawk was in my yard chasing squirrels. In this case, the Red tailed hawk was eyeballing the squirrel hiding among the rose bushes around the pole from which two feeders are hung.
