Certhia discolor
The Sikkim Treecreeper, *Certhia discolor*, is a small, cryptically plumaged passerine bird of the Certhiidae family, known for its distinctive tree-climbing habits. Measuring approximately 12-13 cm in length and weighing 7.5-12 grams, this species exhibits a characteristically long, slender, and decurved bill perfectly adapted for probing. Its upperparts are a mosaic of rusty-brown, streaked with black and buff, culminating in a diagnostic rufous rump, while a prominent white supercilium con...
Found primarily in subtropical and temperate moist broadleaf evergreen and mixed deciduous and coniferous forests, often with an abundance of moss-laden trees. It inhabits mountainous regions at elevations typically between 900 and 3600 meters.
Feeds almost exclusively on small invertebrates, including insects and spiders, which it extracts from tree bark using its specialized bill.
The Sikkim Treecreeper is a diurnal and generally solitary or paired species, though it frequently joins mixed-species foraging flocks outside the breeding season. Its most characteristic behavior is its unique foraging strategy: it spirals upwards along tree trunks and major branches, meticulous...
