The pied falconet, a diminutive raptor adorned in contrasting black and white plumage, measures a mere 7 to 7.5 inches in length and tips the scales between 55 and 75 grams. Despite its size, it is the largest within its genus, Microhierax. Its visage is a striking white, accented with a bold black eye patch extending to the ear coverts, and a yellowish beak. The bird's upper parts are cloaked in black, including the crown, while the primaries boast black with white wing bars. The long tail is similarly black with white bars when viewed from beneath.
The pied falconet can be distinguished by its white thighs and absence of chestnut coloration, setting it apart from its congeners. It is sometimes confused with the Ashy Woodswallow due to some color resemblance, but the falconet's upper parts are a deeper black compared to the Woodswallow's grey-ash hue.
This species favors the edges of deciduous forests and clearings within wooded foothills, often perching atop trees in old cultivation lands with banks and streams.
The pied falconet's range extends from northeastern India to eastern China and throughout Southeast Asia. It is a resident species, remaining within its territory throughout the year.
These raptors are not migratory, preferring to stay within their chosen habitat. They can often be seen perched high in the treetops, occasionally swooping down to capture prey.
The pied falconet emits a shrill, high-pitched scream and a chattering whistle. During courtship, the male produces a rapid sequence of calls that begin excitedly and taper off as the female acquiesces to mating.
Breeding season spans from March to May. Males engage in leaf-presenting courtship displays and bobbing dances to attract females. Nesting occurs in old cavities created by barbets or woodpeckers, with the eggs laid on a bed of leaves or grass. Cooperative breeding is suspected, as they are often observed in small groups.
Within its genus, the pied falconet is similar to other Microhierax species but can be identified by its unique thigh coloration and lack of chestnut hues.
The diet is predominantly insects, supplemented by small mammals, reptiles, and birds. The falconet is adept at capturing prey mid-flight or plucking it from foliage, demonstrating surprising speed and power for its size.
The pied falconet is classified as Least Concern due to its extensive range and stable population numbers.
