アメリカヨタカ Chordeiles minor

Camouflaged to blend into daytime roosts. Intricately patterned with gray and brown. Often roosts along tree branches or on the ground. Feeds at night on large insects. Watch for them flying under bright lights at ballgames or supermarkets. Distinctive fluttering flight style, with wings usually held in a V-shape between bursts of flaps and maneuvers to snatch insects. Very similar to Lesser and Antillean Nighthawks; note voice and location of white wing patch close to base of primaries.
