Taxonomy: Sitta formosa Blyth, 1843, Darjeeling, India.
Relationships obscure; has been placed in a separate genus, Callisitta. Lustrous blue coloration may suggest an affinity with S. frontalis and S. azurea, but E Himalayan centre of distribution and unique plumage pattern militate against this. Monotypic.
