Field Identification: The blue-eared barbet is a robust, short-tailed bird that is around 18 cm in length.

It has a broad, strong bill, and a prominent, crested head. The males and females look alike, with a green head, back, and wings, a red throat, and a yellow belly.

The most striking feature of the bird is the blue patch of skin around its eyes, which stands out against its green plumage. The bird’s bill is black, and the legs and feet are gray.

Similar Species: The blue-eared barbet can be confused with other birds in the barbet family, such as the coppersmith barbet. However, the blue-eared barbet has a much larger blue patch around its eyes compared to the copper-smith barbet, and the latter’s plumage is predominantly brown.

Plumages:

The blue-eared barbet undergoes two molts a year to replace its feathers. During the breeding season, in summer and early monsoon, the adults have bright and vibrant plumage, while outside that period, the birds have a comparatively dull plumage.

Molts:

The juveniles or chicks of blue-eared barbet hatch without any feathers, and after a few days, they start developing feathers, which they continue to molt throughout their lives. As a juvenile barbet reaches its first fall, it molts into the plumage of its first winter, and later the plumage of an adult.

The blue-eared barbet feeds mainly on fruits and insects, and its call is a loud, resonant “tuk-tuk-tuk.” The bird is known for its habit of tapping bills against branches to sound alarms, territory claims, and foraging for food. Conclusion:

The blue-eared barbet, with its beautiful plumage, striking blue patch of skin around the eyes, and its distinctive tapping habits, is a delightful bird to observe in the wild.

It is a common sight in many of the Asian countries, but its numbers have dwindled due to habitat loss and fragmentation. Bird lovers and conservationists should protect these lovely birds to ensure that they remain in our skies and forests for future generations to enjoy.
