[CT Birds] Accipiter in Guilford

The presence of teardrops helps rule out Sharp-shinned.  

But the streaks in the Cooper's and Gos are quite different as well.  

The juv. Northern Goshawk has tear-shaped streaks, but they are larger, darker, and more prevalent or "denser",  and continue further down towards the belly.  In many cases the leg feathers are more densely spotted and there is at least a row of spots in the undertail coverts.  

But streaks fade at a distance.  For the Coop, that large warm tawny, buffy head against a "white" belly is an impression that can be seen from considerable distance.  The juv. Coop is a colorful, pretty, warmly-colored bird.  

The more uniformally chocolate colored, darker Gos gives more of an impression that it may have flown from the lands of Mordor...

Thanks to everyone who responded!  I've learned a lot about this identification.  Great comparison photos Jim.
One question for Frank (and anyone else), who wrote:
>Note the tear-shaped streaks
Is the shape of the streaks helpful for distinguishing between the accipiters?
