This Sharp-shinned Hawk on an old-growth pine isn't looking for food.  The bird is looking for a breeze during San Francisco's unusual Winter 2004 heatwave.  Small birds know when birds of prey are out to kill and flee.  When the hawks and falcons are satisfied, they pose no danger to the small birds.  NOTE:  The Historic old-growth pine seen in the picture has been cut to the ground.  As a result, the hawks are no longer seen.  A City Birds digital photo.
