Certhia nipalensis


14 cm (5½ in). The richest coloured treecreeper in the region.

  • Bright rufous flanks, lower back and rump
  • Almost black crown and mantle with fine buff streaks
  • Broad cream-buff supercilium enclosing dark cheek-patch
  • Rather short and straight bill
  • Very long tail spikes

Sexes similar. Juveniles are duller and browner and look similar like the local race of Eurasian Treecreeper.


Himalayas from west Nepal east to Bhutan, northeast India, northeast Burma, southeast Tibet and southwest China.
Rather common in the Himalayas, rare in China.


This is a monotypic species.
Formerly erroneously treated as subspecies of Eurasian Treecreeper.


Boreal and temperate forests, also in rhododendron.
Occurs in summer from 2300 to 3660 m, lower in winter. Generally higher than Sikkim Treecreeper but lower than Bar-tailed Treecreeper and Eurasian Treecreeper, however some some altitudinal overlap with all three species.



Feeds on arthropods.
Forages like other Treecreepers on trunks and lower branches of trees, often searches for food among epiphytes.
Usually seen singly or in pairs, sometimes in small flocks or in mixed-species flocks, however less often than other treecreepers.


Not well known. Breeding season presumably from April to June. One recorded nest in a fissure of an old fir tree contained 3 eggs.


A resident species with some seasonal altitudinal movements.
