But it might be a she, not a he. In the accipiter group (sharp-shinned, Cooper's, and northern goshawk), the females are bigger than the males.
Yeah, I know, scary stuff...
Hmmm, I don’t know whether it was male or female then. There was no other object for me to compare it to, but I’m guessing it was around 15-16”. Are the females markings different? What should I look for the next time I see it? It’s come around twice in the last week.
