Yesterday, we were walking on the Audobon Bird Loop at Marymoor Park and a hawk flew past us. We were able to photograph it from the tree it landed in. We are pretty sure it is a Sharp-shinned but would like some confirmation. Along with confirmation, it would be nice to know how you came to that conclusion, as we were having difficulty differentiating between a Sharp-shinned and a Coopers Hawk.
I added the photos to my Flickr for viewing. Please let me know if you have any issues or questions!
