Sulphur-billed Nuthatch (Sitta oenochlamys)


Taxonomy

French: Sittelle des Philippines German: Philippinenkleiber Spanish: Trepador filipino
Taxonomy:

Dendrophila oenochlamys

Sharpe

, 1877,

Guimaras, Philippines

See remarks under S. solangiae, to which it is most closely related; Hainan race chienfengensis of latter species may form link between them (both are yellow-billed, whereas S. frontalis has red bill). Geographical variation partly clinal, colour saturation and dominance of lilac tones in plumage increasing from N to S through islands. Six subspecies recognized.
