Here are the remains of the hawk’s nest from last spring. It sat on its branch intact through the late fall, and then I saw a bird up inside, picking it apart. I don’t know what the purpose would be, unless because hawks feed meat to their young, the nest has edible bits that other birds seek after they’ve eaten a lot of their other food.
This is something unknown. It may be a canker, it may be the remains of some animal killed by the hawks. I made the photo as close-up as I could, and I can’t tell.
Here’s a picture from earlier in the year. A while back, 2012, there was a huge storm in Ohio called a derecho, and when I was driving home from work that day, I was stuck in traffic at an intersection, a few blocks from my street. A whirlwind came up right by the roadside. (I was thinking, “Let’s not have a tornado now, I’m almost home.”) Out my backdoor, while the sky was not quite dark as night, but dark, I saw squirrels on the side of the oak “tree-surfing”. At that time, I didn’t get a picture of this behavior, but last summer, during a heavy thunderstorm, I did.
This picture is even older, showing the house (on the right, with chimney) I lived in in Chauncey, Ohio. The little dog was my smart border collie mix, and her name was O’Keefe.
