Yes I did compare its size to a Red-tailed Hawk but with a longer tail.
We had just seen Red-tails soaring but in a different area. Gyrfalcon
didn't come to mind because it would be even less likely than a Goshawk.
The markings underneath immediately ruled out Red-tail and then my mind
turned to Northern Harrier because the white undertail coverts
prominently stood out and I transposed them to the rump. Mind you
because this bird was diferent than others I have seen, I systematically
ruled out each of the more common species first but with a "less than a
minute" look it is quite frustrating. Once the bird is gone you have to
flash back to what you remember about the bird. I did not say Accipiter
from the git-go but came round to that as I eliminated others.

I will agree that the rufous may not show up in all lights but the
lighting was good and there was not even a hint of buff on the
underneath of that bird.

If it was not a Goshawk then I don't know what it is because it didn't
"feel" like a Cooper's Hawk but I definitely will not count it as a Gos
this time. If anyone can definitely give me one of those for my list
I'll take!!!
