About Tarsiger chrysaeus Hodgson, 1845
This is the golden bush robin, scientifically named Tarsiger chrysaeus Hodgson, 1845. It is a 14–15 cm long songbird in the family Muscicapidae, named for its characteristic golden coloration. Full-grown individuals weigh between 12 and 15 grams. Male golden bush robins have brownish olive upperparts and bright yellow-orange underparts. Females share this same color pattern, but their colors are duller and less vibrant than males. Juvenile males have dark brown plumage with buff streaks above and below the tail; this pattern is less distinct in juvenile females. This species is distributed across the Himalayan mountain range and surrounding highlands of Bhutan, China, India, Myanmar, Nepal, Pakistan, Tibet, and Thailand. It primarily inhabits open areas including temperate forests, bamboo forests, grassland, and shrubland. In mountainous southern China, golden bush robins, alongside white-browed bush robins, chestnut-crowned bush warblers, and Gould's shortwings, are part of a rare group that exploits human disturbance to their primary temperate forest habitat. This behavior is thought to be a modification of the species' pre-existing dietary habits, occurring as human activity increasingly exploits natural resources in the region.
