Large-Billed Crow or House Crow?

General appearance

The large-billed crow, as the name suggests, is notable for its relatively large beak. These crows are generally black, even though a gray or silver sheen may appear over the feathers in bright sunlight. Their eyes are often a stark contrast in a striking shade of white or pale blue.

Male vs female

Sexual dimorphism is less prominent in large-billed crows, making it difficult to distinguish males from females based on physical appearance alone. Both genders share similar coloration and size, although males tend to be slightly larger.

Juvenile

Juvenile large-billed crows resemble adults but tend to have lighter-colored eyes, usually a duller blue or gray. Additionally, juveniles may be identified by the comparatively smaller size of their beaks, which gradually increase as they age.

Primary habitat

The large-billed crow is native to South and Southeast Asia. It prefers tropical climates but can also adapt to various environments like forests, grasslands and human settlements.

Additional range

Sometimes this species extends its range north to the Russian Far East and Japan, likely due to increased availability of food resources.

Natural diet

The large-billed crow is omnivorous, feeding on a diverse array of natural foods. Its diet primarily consists of insects, small mammals, fruits, grains, and carrion. It is also known to consume eggs and nestlings of other birds. It forages in a variety of habitats, including forests, fields, and urban areas, demonstrating great adaptability in its dietary habits.

Bird feeders

At bird feeders, the large-billed crow is attracted to a range of offerings. It commonly consumes seeds, nuts, and suet. These birds may also take advantage of kitchen scraps, such as bread and meat, provided at feeders. Their adaptable nature allows them to exploit various food sources found around human habitation.
