While I was out tending my tractors (keeping it legal, grin) I noticed a strange occurrence.
Next door is a fairly young densely wooded area that crows and in the winter Cooper's Hawks frequent.
Yesterday I saw a couple of crows, in flight, chasing a hawk away from the area. One crow was persistent and would not give up. At one point the crow flew up alongside and slightly below the hawk and as best I could tell, jabbed at the under side of the neck of the hawk with it's beak.
Immediately after that the crow backed off, the hawk quit flying, was just gliding and slowly loosing altitude. Within a hundred yards it just nose dived into the ground. I watched for a time and didn't see the hawk get up.
Any idea as to what the crow did to the hawk? I like those hawks, especially in the spring and early summer when I mow and make windrows and they hover about 50 feet above you, waiting for you to flush out a field mouse. Watching them after the initial kill with their proud posture is nice.
One time I saw a rat run into a ww and he did too. He swooped down and the rat had moved. He kicked the grass around for a bit and moved up the row and the next thing you know he had it.
