This hawk visited our backyard briefly yesterday. The bird looked like it was trying to keep cool by panting and holding its wings away from its body. Air temperature was about 100 degrees. The blue bungee cord hanging from the mesquite tree branch holds our hummingbird feeder. All of the small backyard birds managed to fly out of the yard safely this time.
But last March, when a hawk flew in the yard, a frightened mourning dove crashed into the glass door and fell to the patio floor. My son tried to help the dove but its neck seemed broken. So, he put the bird out onto the lawn and just a minute later, the hawk took it away. After all, hawks do have to eat.
The next picture is kind of sad, but hopefully, not too gross. This was the mark left on the window where the dove collided with the glass. It was just below where we had stuck a bunch of post-it notes to the glass to help prevent birds from flying into to it. The cardboard was just there to make the bird shape easier to see. The distance between wingtips measured ten inches.
I observed the following hawk at Sabino Canyon in January. I don't see hawks very often and they're pretty hard to identify. I think the first two are immature Cooper's hawks and the one in the bottom picture is an adult Cooper's. Perhaps some birders can let me know what they are if they're not Cooper's hawks.
