Sharp-shinned Hawk, Accipiter striatus
Above and below, juvenile Sharp-shinned Hawks, distinguishable from the
very similar Cooper's Hawk by their smaller size, proportionately smaller
heads, with eye more nearly centered on the head rather than further
forward, a squared off rather than rounded tail, thinner legs (toothpicks
rather than pencils), and, in juveniles like these, coarser and more blurry
stripes on the underparts. These hawks winter regularly in my area, but compared
to Cooper's I've had very little luck photographing them.
