Northern Hawk owls, also called simply "Hawk owls," are unique among owls. They have long tails and pointed wings and their flight is like accipiter hawks. In addition, they tend to bob their tails when perched and are adept at hovering like kestrels. Their long tail distinguishes them from all other owls. This owl is about the size of a crow.
Sharp-shinned and Cooper's hawks are accipiter hawks built for speed, because like the Hawk owl, they hunt other birds in flight. Nailing a rodent to the ground requires speed and power, but not flight maneuverability. Both species of accipiter hawks are winter regulars in Maine. When there is thick snow cover, they stalk feeder birds, as easy pickings as a senior citizen's buffet or a Petco rat. Pass the tartar sauce and the Pepcid, please.
