Adult female.--Differs from the male in lacking the ochraceous of crown and the maroon of shoulders and back, the entire upper parts being green.

This species is closely related to Sphenocercus formosæ and specimens of the two species should be compared. It is not uncommon in Calayan and Camiguin. We were first led to search for it by hearing its weird, prolonged cry which is remarkably like that of a child in pain. Having located the tree in which one of these birds was resting it was difficult to see the bird as its yellowish green under parts were in perfect harmony with the color of the leafy branches.
