398 PYCNONOTID &. 
Mahanadi, Hastern Bengal, hills and plains South of the Brahma- 
putra, Burma, Siam, Shan States, Yunnan. In Peninsular Siam 
and Burma it 1s replaced by the next form. 
Nidification. This Yellow Buibul makes a nest much like that 
of the two genera last described, but deeper and better built and 
nearly always made of tan-coloured materials amongst which 
dead leaves are always prominent. The lining is of fine grass- 
stems, occasionally of fine moss roots or similar material, whilst 
one nest was lined with mithna (Bos frontalis) hair. They breed 
most numerously in May and June but eggs are laid almost any time 
between early March and late August or even early September. 
The full clutch numbers two to four and the eggs differ from 
those of the other species of Otocompsa in being more profusely 
stippled and speckled all over with very fine markings varying in 
colour from reddish- or creamy-pink to deep purple-red or red- 
brown. 100 eggs average 22°3x 165 mm. and vary in length 
between 24°2 x 16-4 and 20°5 x 16°S mm. and in breadth between 
21-9 x17°2 and 23:1 x 15°3 mm. 
Habits. In its actions, flight and food this bird is a true 
Otocompsa but it is often found in light serub- and bamboo-jungle 
and sometimes on the outskirts of deep forest. In Assam it 
frequents the vicinity of the hiil villages, cover of any kind in and 
around patches of cultivation and open places near roads and 
streams. It collects in the cold weather in flocks of half-a-dozen 
to a score or more individuals and frequents indifferently scrub, 
bushes, bamboos and high trees. ‘They eat both insects and fruit 
and I have seen them on the ground eating wild strawberries and 
also feeding on termites as they came up from the ground. They 
are, for Bulbuls, not noisy birds and their song, which may be 
written ‘* Weet-tre-trippy-wit,” with the last three syllables 
repeated twice or more, forms a rather sweet though jerky little 
song. They are found commonly up to 3,500 feet and tarely up 
to 5,000. 
(414) Otocompsa flaviventris minor. 
Kuoss’s BuacK-HEADED YELLOW BULBUL. 
Otocompsa flaviventris minor Kloss, Ibis, 1918, p. 200 UXoh Lak, 
S.W. Siam). 
Description. ‘‘ Smaller than 0. fl. flaviventris (Tickell) of Chota 
Nagpur; wing 83mm. or less ” (A’/oss). 
Distribution. Peninsular Burma and Siam and throughout the 
Malay Peninsula. 
[t is only after some hesitation that I have accepted this form. 
It certainly averages smaller, but the sinallest Malay bird and the 
smallest bird from Assam both have a wing of 77mm. On the 
other hand, Kloss’s minor seems also to be a trifle darker and to 
have a decidedly shorter crest. 
Nidification and Habits. Nothing recorded.
