Large-billed Crow

Overview

The Large-billed Crow is a widespread and adaptable species found across much of East, South, and Southeast Asia, from the Himalayan foothills to Japan. It is one of the most familiar crows across large parts of Asia, thriving in both forested and urban settings.

Multiple regional subspecies exist across its extensive range, with some variation in size and bill shape, though all share the same overall glossy black plumage.

Feather Identification

Feathers are entirely glossy black with a strong blue-purple sheen across the wings and back in good light.

• Bill-related cue: While bill shape isn't a feather trait, this species' heavy, arched bill often distinguishes live birds; feathers alone show typical crow shape but slightly larger dimensions in bigger subspecies.
• Flight feathers: Broad, strong primaries and secondaries suited to powerful, direct flight.
• Tail feathers: Squared or slightly rounded tail feathers, sturdy and glossy.
• Similar species: Very similar to other all-black Asian crows such as Jungle Crow and Carrion Crow; overall larger feather size and steeper forehead profile in the living bird help separate it, though feathers alone can be difficult to assign to species with certainty.

Plumage Notes

Adults are uniformly black with a glossy sheen, most pronounced on the head, back, and wing coverts. Juveniles are duller and browner-black, gaining full gloss as they mature into adult plumage.

No significant differences exist between males and females. An annual complete molt follows the breeding season, refreshing the glossy black plumage.

Habitat & Range

This crow occupies an exceptionally broad range of habitats, from dense forests and mountain slopes to farmland, villages, and large cities across much of Asia, including India, China, Japan, and Southeast Asia. Its adaptability to elevation and habitat type is a key reason for its wide distribution.

Most populations are resident, though some populations at higher elevations may shift to lower ground in winter.

Behavior & Field Notes

Large-billed Crows are intelligent, adaptable foragers found in pairs, family groups, or larger flocks, especially around food sources such as farmland or urban refuse areas. Diet is highly varied and opportunistic, reflecting the species' broad habitat use.

Nests are bulky stick platforms placed high in trees. The call is a deep, resonant "kaa" often repeated, generally harsher and deeper than smaller crow species. Its comfort in cities, especially across Japanese and Indian urban centers, makes it a frequently observed species.
