The American kestrel (Falco sparverius) is the smallest and most common falcon in North America. The American Kestrel is pale when seen from below and warm, rusty brown spotted with black above, with a black band near the tip of the tail. Sexes are of similar size, but males have slate-blue wings; females’ wings are reddish brown. During courtship displays, female flies slowly with stiff, fluttering wingbeats, the wings held just below horizontal. Male repeatedly flies high, calling, and then dives.
