Moore's Olive Bulbul.
Pycnonotus simplex Less., Bev. Zool., 1839, p. 167 (Sumatra); Blanf. & Oates, i, p. 292.
Vernacular names. None recorded.
Description. Upper plumage brown with a greenish tinge, slightly fulvous on the rump and upper tail-coverts; wings and tail brown, the outer webs washed with greenish; whole lower plumage buffy-brown, slightly streaked in places with darker ochraceous; under tail-coverts dark ochraceous with paler edges; under wing-coverts and edge of wing pale ochraceous.
Colours of soft parts. Iris orange-red, pale red, whity-pink; upper mandible dark horny-brown, lower mandible paler; legs and feet fleshy- or reddish-brown.
Measurements. About the same as plumosus. Wing 80 to 88 mm.; culmen about 15 mm.
Distribution. Tenasserim, from Mergui, South through the Malay Peninsula to Sumatra. The Javan form has been separated by Hartert (Nov. Zool. ix, 1902, p. 561) as P. prillwitzi and the Bornean form also seems different from the Malay bird.
Nidification. Nests and eggs taken by Mr. Kellow at Simpang in the Malay States were, like those described by Davison, taken in thick jungle in high bushes. They are rather more richly coloured than those of the two preceding species and they measure about 21.0 x 15.9 mm. Mr. Kellow's eggs were taken in January, February and April.
Habits. Those of the genus but this species is a bird of thin forests and does not haunt cultivated or inhabited areas.
