I took the liberty of sending the photo to Brian Wheeler and he agrees with David. Here is what Brian said:
A juvenile Cooper's Hawk. An accipiter by very long tail. A Cooper's Hawk because it has the longest tail of the three species. This bird shows a very long distance from the primary tips to the tail tip is quite an amount. This bird shows a pale supercilium, which is more associated with juvenile Northern Goshawk; however, many juvenile Cooper's Hawks also show this mark. Markings on wing align with Cooper's Hawk. Pale edging on median and greater coverts but lack of pale bar on greater coverts rules out most Northern Goshawks.

This is a Cooper's Hawk. David Tonnessen Colorado Springs, CO -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.
