Have you ever observed a Cooper’s hawk ( COHA) tussle with an eagle in the sky? SKY— my definition — one- hundred twenty feet of altitude or more. Under that altitude, I could call the air. Bet you have not. If you did it was in migration time.
How about a COHA tussle with a raven or an osprey or a Red-tailed hawk or a goshawk?
I have observed the NG tussle with Red-tailed hawk, osprey, raven, eagle, and Turkey Vulture. But never with a COHA. All in the sky. You will probably never observe a COHA tussle with other raptors in the sky, because COHA to no go into the sky to tussle.
If you do not live near a major migration route, you will probably never observe a COHA in migration. If you do not live near a major migration route you might never observe a NG in migration. If it is not migration time, that NG in the sky is probably a resident hawk.
If you observe an accipiter in the sky and it is not migration time, then that accipiter is probably not a COHA. Here is my take on the situation. I believe, I have never observed a COHA in the sky during non- migration time. Which leads to my profound statement — COHA do not have an affinity for the sky— only during migration! So, know your migration times, and add a fudge factor of a week or two.
The thought: Now this web site is starting to weave and revolve into some of my other posts and will work its way into many other up- coming posts. And I know what you are thinking.NB.
