This paper describes the hunting tactics of the Tiny Hawk, Accipiter superciliosus fontanieri, in a Costa Rican rain forest, where it appears to be a hummingbird specialist. Three tactics were used by the hawks to hunt hummingbirds: typical Accipiter still-hunting (probably not specifically for hummingbirds), waiting in ambush by a hummingbird's regular territorial perch, and flying rapidly between the perches of several territorial hummingbirds. Relative use of the latter two tactics may reflect the local density of territorial hummingbirds.
