Silver-Eared Mesia: A Closer Look at Its Colors

Foraging flocks and a history of escape from captivity

The Cornell Lab’s eBird account describes mesias moving in noisy groups through hill and submontane forest, sometimes with other species. It also records established populations descended from captive birds, including in Hong Kong. That is a history of human movement of animals, not simply an extension of the bird’s native range.

The Hong Kong Bird Watching Society’s local account adds a firmer basis for the 2021 diet and flocking discussion. Insects and fruit both contribute to the diet; observed flocks commonly include roughly five to 20 birds, while larger groups have also been recorded. Birds forage from undergrowth into the lower canopy and may associate with red-billed leiothrixes and other small birds.

Local breeding records include nest-building activity and recently fledged young, but the Hong Kong account says its nests and eggs have not been described there. A precise clutch size or nest-building timetable should therefore name the population and source it describes. The photographs below preserve the original photographers’ posts and provide several views of the plumage.

The Hong Kong Bird Watching Society’s account places the species’ natural range from northwest India through Nepal and much of continental Southeast Asia, south to the Malay Peninsula, with a population on Sumatra. Thailand, Vietnam and Laos belong within that wider geographic setting. Hong Kong’s established ex-captive population is a separate part of its distribution story.

The 2021 feature also emphasized that both males and females have colorful plumage. Its broad shorthand—red-orange for males and yellow for females—does not identify which feather patches it means. That alone is not a sufficient rule for assigning sex to the individual birds in this gallery; the forehead, throat and other markings need to be checked against a reference that specifically describes the relevant birds.
