[This bird is common at the Ja and on the coast, but is 
less so in the strictly forest-country between, for its resort 
is the neighbourhood of villages. It attracts attention by its 
appearance, on account of the red wattle over the eye, which 
in life is very conspicuous. Its little song is very noticeable 
also, because of the wide difference in pitch of the four 
notes which compose it. A musical friend has told me 
what notes of the scale it sings, but I have forgotten them. 
It has the same habit as Diaphorophyia castanea (see ‘ Ibis,’ 
1905, p. 94) of making a sharp Happing sound with its 
wings as it flies. This is done but occasionally, evidently 
to attract attention, and perhaps only by the male.—

The nestling is rufous like the old female, but is mottled 
with whitish longitudinal centres to the feathers of the upper 
surface, which have also black margins. ‘The crown and 
sides of face are black with rufous margins to the feathers ; 
the under surface is white, with a faint tinge of cinnamon- 
buff. 
The young male is also similarly coloured and mottled, 
shewing that the first plumage resembles that of the adult 
female, and is not black.
