Adult. Head, neck, throat and breast wood-brown, darker above, paler below, more 
drab-colour on head, passing on tlie rest of upper surface, wings, and tail into 
Mars- and walnut-brown; under tail-coverts, flanks and thighs of the same colour 
passing into wood-brown on the lower breast. Bill black, horn-brown at tip. In 
some specimens, it is yellowi.sh white at the tip and over part of the lower mandible . 
Adult male and female. Alike in coloration, the latter is perhaps a triple larger. 
Immature. Differs little from tlie adult. The head, neck and breast is wa.shed more strongly 
with a rufous tint, so that the colour here contrasts less strongly with that of the 
rest of the body, and across the throat a rufous collar is percej)tible (Manado, 
C 5186, Limbotto Q, C 1814). 
Lord Walden remarks: “In P. celebensis, the fully adidt bud loses the bright 
yellow-rufous dun-, throat-, neck-, and breast-plumage of the younger bird. These 
parts become very pale fulvous and contrast with the dark chestnut of the remaining 
lower region. . . . Tlie young bud is bright rufous throughout” (1).
