Hello. In Ft Lowell Park in Tucson, cooper's hawks have nested there for
years - 1 block from a big great tailed grackle colony and the only
interaction I ever saw between the two was when a few great taileds got too
close to the cooper's nest - they were then chased. The coopers never went
over to the grackle colony or tried to take young grackles on the ground.

The coopers were constantly mobbed by western and cassin's kingbirds
everywhere in the park (being struck repeatedly as the kingbirds took turns)
and they were usually successful in distracting the cooper's at least. One
WK nest was on a ballfield light - 1 block from the cooper's nest and the
grackles didn't go there either.

There were some missing cassin's parent birds and some nests lost and I
assume the coopers took a few of them. I saw the cooper on once occasion go
straight up after a wk but didn't get him.

On the squirrels - I have read numerous reports of the fox squirrel
approaching a cooper sitting in a tree and the cooper left.

Maybe it's different with the gray squirrel.

Thanks for your interesting post.
