ceasar, from your post.

As you can see the Cooper's hawk is considerably bigger than the Sharp-shinned hawk even when comparing a male of the former with a female of the latter. Interesting comment in it also at the bottom of the list about the relation of size and body weight between the Cooper's and the Peregrine.

We went to the link you supplied.

The numbers back up what we posted. A large female 13" Sharpie would be undistinguishable by size from a 14" small male Coop.

Sharp-shined male 9-11 Female 11-13
Cooper's male 14-16 Female 16-19

Two of our field guides list them,

Sharp-shined 10-14
Cooper's 14-20

The Bud we have been referring to is Bud Anderson from the Falcon Research Group in Bow WA.

FRG.ORG

One of their projects are tracking the 9,000 mile migration of one sub-group of Peregrine Falcons from South America to the Arctic with radio transmitters on the birds and GPS to show where they are 24-7.

I posted the link for info. only.

I think it is a Cooper's myself. Never the less, it should be noted that a male Cooper's hawk is about 2 times as massive as a female Sharp-shin and this can often be seen in their overall body structure. It is helpful to have a frame of reference too.
