The rusty-flanked treecreeper or the Nepal treecreeper is a species of bird in the family Certhiidae. It is found in northern India, Nepal, Bhutan and western Yunnan. Its natural habitats are boreal forests and temperate forests.
Region
Himalayas and Southwest China
Typical Environment
Occurs from northern India through Nepal and Bhutan into western Yunnan, China, mainly in montane coniferous and mixed broadleaf–conifer forests. It favors mature stands of fir, hemlock, spruce, pine, and oak with abundant moss and lichen. Old trees with deeply fissured bark provide optimal foraging surfaces and nesting crevices behind loose bark. It is generally sedentary, though it may shift altitude seasonally following food availability.
Altitude Range
1200–3600 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
This cryptic tree-trunk specialist uses a stiff, pointed tail as a prop while it spirals up rough bark in search of tiny prey. Its warm, rusty flanks help separate it from similar treecreepers in the Himalayas. Often inconspicuous, it may join mixed-species flocks in winter and is more easily detected by its thin, high-pitched calls.
Temperament
shy and cryptic
Flight Pattern
short undulating flights between trees
Social Behavior
Usually solitary or in pairs while foraging, sometimes joining mixed-species flocks in the non-breeding season. Breeds in cavities or behind loose bark, constructing a cup of twigs, moss, and fibers. Likely monogamous, with both adults involved in nest defense and provisioning.
Migratory Pattern
Partial migrant
Song Description
Song is a thin, high, slightly tinkling series of notes and short trills. Calls include sharp, insect-like seee or tsee given while moving along trunks.
