Tachornis infumatus McGregor, Bull. Philippine Mus. (1903), 1, 5.

Tachornis pallidior McGregor, Bur. Govt. Lab. (1904), 25, 27;

Bohol (McGregor); Cebu (McGregor); Luzon (McGregor); Mindanao

(Celestino); Ticao (McGregor).

Adult.--Upper parts dark brown; nearly black on head, neck, and back

which have a faint green gloss; feathers of rump and upper tail-coverts

lighter brown and narrowly fringed with gray in unworn plumage, the

tail-coverts with dark shafts; wing-feathers blackish brown, glossy on

outer webs; short primaries narrowly edged with white on inner webs;

tail of the same color as wings; sides of head brown; chin and throat

light drab-gray, merging gradually into the dark drab-gray of the lower

breast and abdomen where the feathers are narrowly edged with whitish;

stiff feathers in front of eye white with brown tips. Length in flesh,

114; wing, 119; lateral rectrices, 50; central rectrices, 31.

This species is easily recognized by the deeply-forked tail and

peculiar paired toes; it is a near relative of Tachornis infumata from

which it differs chiefly in having a paler chin and throat. It has

been found in small numbers in the islands from which it is recorded.
