It can overtake fast-flying prey like swifts, swallows and bats and also seizes hummingbirds, parakeets, small waterbirds, large insects and lizards.

The Bat Falcon (Falco rufigularis) is a falcon that is a resident breeder in tropical Mexico, Central and South America and Trinidad. It was long known as Falco albigularis; the name Falco fusco-coerulescens or Falco fuscocaerulescens, long used for the Aplomado Falcon, are now believed to refer to the present species (AOU 1948).

The female Bat Falcon, at 30.5 cm length, is much larger than the 23 cm long male. Adults have a black back, head and tail. The throat, upper breast and neck sides are creamy white, the lower breast and belly are black, finely barred white, and the thighs and lower belly are orange. Young birds are similar but with a buffy throat. The call of this species is a high pitched ke-ke-ke like American Kestrel.

It is probably closely related to and looks like a small version of the Orange-breasted Falcon. These two, in turn, are probably closest to the Aplomado Falcon and constitute a rather old American lineage of Falcos.

This small dark bird of prey inhabits open woodlands and forest clearings. Bat Falcons perch conspicuously on high open snags, from which they launch aerial attacks on their prey. They hunt bats, birds and large insects such as dragonflies. The smaller male takes more insects, and the female more birds and bats. The flight is direct and powerful. This fierce little falcon is partly crepuscular, as the bats in its diet suggest. It lays 2-3 brown eggs in an unlined tree hole nest.
