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. 



Hab. Malacca, Sumatra and Borneo. On the latter island
