About Sitta oenochlamys (Sharpe, 1877)
The sulphur-billed nuthatch, with the scientific name Sitta oenochlamys (Sharpe, 1877), is a bird species belonging to the family Sittidae. This species is endemic to the Philippines. Its natural habitats are tropical moist lowland forest and tropical moist montane forest. It is commonly found in mixed-species flocks alongside blue-headed fantails, sunbirds, flowerpeckers, and other small forest birds. Its natural habitats include tropical moist lowland and montane primary forest and secondary forest, reaching up to 2,060 meters above sea level. It is more common at higher elevations. The IUCN Red List has assessed this bird as a least-concern species, as it remains common throughout its large range. Its population is currently decreasing, due to habitat loss and deforestation occurring in the Philippines. Further studies are recommended to improve understanding of this species, its population, and its conservation status. The sulphur-billed nuthatch feeds on insects. It can be found alone, in pairs, in flocks of up to 20 individuals, and also joins mixed-species flocks. It is very active, and forages near the tree canopy; it is often seen on tree trunks, where it gleans food from loose bark, moss, or epiphytes. Individuals collected in breeding condition with enlarged gonads have been recorded between January and May. Very little else is known about this species' ecology and behavior.
