A Manual of Philippine Birds

by Richard C. McGregor

This is a very distinct species which is found only in the mountains of Mindanao.

Genus PRIONOCHILUS Strickland, 1841.

Bill short and stout, very wide at base; gonys decidedly convex; first primary less than one-half the second or wanting. The Philippine species that are usually placed in this genus are not uniform in generic characters. P. johannæ has a short first primary and a moderately stout bill; it resembles P. ignicapillus and is probably a typical Prionochilus. P. olivaceous has a short first primary and the bill somewhat stouter than P. johannæ. Prionochilus quadricolor, P. bicolor, and P. inexpectatus resemble one another in having the bill short and very stout and the true first primary absent.
