Bat Falcon

The Bat Falcon is a compact, powerfully built small falcon known for its speed and agility in pursuit of aerial prey. Adults have a blackish head, back, and upperwings, a white or buffy throat and upper breast, and a rich rufous-orange lower belly and thighs, with fine black barring on the flanks. Despite its small size, it is a bold and capable predator, often seen perched conspicuously on a high dead snag scanning for prey before launching into fast, direct pursuit flights.

Key field marks

• Small, compact falcon shape with pointed wings.
• Black crown, back, and upperwings.
• White/buffy throat and upper breast; rufous-orange lower belly and thighs.
• Fine black barring on the flanks.

Similar species

Orange-breasted Falcon is larger and heavier with a more extensively orange breast and different barring pattern; the two can be confused but Orange-breasted Falcon is much rarer and larger. Bat Falcon's smaller size and sharply demarcated pale throat/dark head pattern help distinguish it.

Bat Falcons favor forest edge, clearings, gallery forest, and open woodland, frequently near rivers, lakes, or other open areas that concentrate flying prey, from lowlands up to about 1,500-2,000 m. The species ranges from Mexico through Central America and across most of South America to northern Argentina. It is a non-migratory resident, often nesting on cliffs, in cavities, or on tall structures near open hunting grounds.

Voice

A sharp, high-pitched series of "kee-kee-kee" notes, given especially near the nest site or during territorial disputes.

Feeding

Bat Falcons are renowned for hunting bats at dusk and dawn as they emerge from or return to roosts, using extremely fast, agile flight to snatch them from the air; they also take small birds and large flying insects such as dragonflies and beetles, often eating insect prey on the wing.

Nesting and breeding

Pairs typically nest in natural cavities, on cliff ledges, or increasingly on tall human structures such as towers, rather than building a stick nest of their own. Both parents help defend the nest site and provision the young.
