Although this species was observed by me at the Cocoa Research
Station, I was unable to obtain any specimens. It was also seen
commonly at Semporna, Siamil Island, Kalabakan, Brantian Estate,
and at Tuaran, always associated with cultivated areas. The birds
obviously were breeding at Tenom in December, and several young
were taken. In some, the molt of the wings, body, and tail had
begun.

[Male] testis 6 x 5 mm., January 1, 1963, MCT 3553; [Male] testis small,
January 1, 1963, MCT 3554; [Male] testis 6 x 4 mm., January 4, 1963, MCT

[Male], March 6, 1963, ADG 16; [Female], March 6, 1963, ADG 17; sex?,
March 6, 1963, ADG 15.

The specimens were netted in scrub-grassland at Tenom. The size of
the testes of the Tenom specimens indicated that the birds were
breeding.

This most common of the "brown" bulbuls at the Cocoa Research
Station frequented shade trees (_Trema orientalis_). One bird fed
on small red peppers, Capsicum sp. Some of the September-taken
specimens were in breeding condition.
