Hi Tommy. Happened to come by this Accipiter from San Diego. However, imo it looks better for Cooper´s Hawk. Reasons for that is: 1. Altough we are not able to see the nape, the dark crown stands out and usually contrast with the paler nape. 2. The greyish ear-coverts (good contrast with the dark crown) suggest a male (male and female Sharp-shinned would have rufous cheeks) Someone might argue that the white tail lack the wide tips of Cooper´s but that might just be due to wear. The important differences in tail feature of Cooper´s & Sharp-shinned is best view from the underside. JanJ

Hi Jan! You´re quite right, its a Cooper´s Hawk, the size of the head compered with the size of body, also indicates a Cooper´s. By the way, the species are easier to distinguish while flying ;-) I´ll see to that the name will be corrected. Tommy
