234 BIRDS OF THE 
This rather quiet bird frequents low jungle and the under- 
growth of high forest, where it feeds upon insects. 
This species is known from Malacca, Sumatra and Borneo, 
where it seems to be spread over the whole island, having 
been recorded from Banjermasin (Mottley) and Moeara 
Teweh on the Barito River, Sandakan Bay (Guillemard) and 
N. W. Borneo.

An immature male and an adult female with a nestling, 
all from Nanga Raoen, and ten specimens from the Bruny 
River (Upper Mahakkam). The younger bird differs from 
the adult in having the crown strongly tinged with rusty 
brown, a shade of which color -is also to be seen on the 
abdomen and especially on the thighs; the white beard- 
spot is fully developed, while the white edging of the black 
gular spot is but faintly indicated. In the adult bird the 
white edging is formed by the lateral and hindmost black 
feathers of the throat having a rather broad and pure white 
subterminal band. The young bird seems to have no black 
on the throat, the extent of black in our immature bird 
being less than in the adult, and some of the lateral 
feathers being gray with a tendency of getting black, and 
showing a small central spot of white. — Iris in the adult 
bird red, in the immature one brown, bill in the adult bird 
black, lower mandible pale blue, while the latter is yellow 
in the younger bird, feet grayish blue. 
The nestling has the entire head, neck and lower sur- 
face uniform sooty brown; back, wing and upper tail-coverts 
chestnut. The white spot at the angle of the bill is fully 
developed, as also the white spot behind the eye.
