In this beautifully coloured and aberrant species, the head, 
throat, breast, belly, under and upper tail-coverts, as well as 
the chin, are white, with a slight tinge of yellow; a band of 
bright brimstone-yellow passes from the forehead over the eye, 
which, however, the bird quickly loses after death. The rest of 
the bird is shining umber-brown, the wing-coverts being pointed 
with well-marked triangular white spots, and the scapularies and 
belly streaked with white lines along the shafts. The wing- 
feathers are greyish brown, with a white edging on the under¬ 
side near their bases; the tail-feathers are rather darker than the 
wings; the under wing-coverts are brownish grey, partly streaked 
with white. The irides are umber-brown, the naked space round 
the eye violet-grey. The beak and feet are blue-black. 
P. leucocephalus is as common as the preceding species, and 
is found in the same districts, particularly on the high trees with 
thick foliage. In its stomach we found berries, insects, and figs. 
With the fruit of the latter the face often becomes stained yellow.
