recognises eight subspecies: ''Pericrocotus solaris solaris'' found in the Himalayas and northern and western Myanmar; ''P. s. rubrolimbatus'' in eastern Myanmar and northern Thailand; ''P. s. montpellieri'' in southern China; ''P. s. griseogularis'' in southeastern China, Taiwan, northeastern Laos and northern Vietnam; ''P. s. deignani'' in southern Laos and central Vietnam; ''P. s. nassovicus'' in eastern Thailand and southern Cambodia; ''P. s. montanus'' in western Malaysia and Sumatra; and ''P. s. cinereigula'' in Borneo. The '' Handbook of the Birds of the World'' considers that ''montanus'' and ''cinereigula'' form a separate species.

. The adult male has a dark grey head and mantle, a pale grey chin, an orange-yellow throat and blackish wings. The underparts, lower back and tips of the greater coverts are orange. In the female, these parts are bright yellow instead. The eyes, beak and legs are black. The immature bird is similar to the female but has yellow-olive bars on its back.


Distribution and habitat

This species ranges from the eastern foothills of the Himalayas through northeastern India, southern China, mainland Southeast Asia to Sumatra and Borneo. Its habitat is
montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial ...

Behaviour

When not breeding, this minivet forms small parties with fewer than 15 individuals and also large flocks of dozens of birds; it sometimes joins

The male has been observed walking towards the female while holding a flower in its beak; the male swung its head, touched the female's beak and dropped the flower, and then they mated. The nest, constructed by both sexes, is built on a branch or fork of a tree. It is a steep cup made of

The male and female raise the brood together, and subadults have been seen helping them. Moulting occurs from June to October.


Status

This species has a large range and stable population, so the IUCN has assessed it as a
least-concern species A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. T ...
