(412) Otocompsa emeria peguensis, subsp. nov.
THE BURMESE RED-WHISKERED BULBUL.
Vernacular names. Boh-ka-lone (Burmese).
Description. Similar to the Southern Red-whiskered Bulbul but with broad fulvous-white tips to the tail-feathers as in emeria. In O. e. fuscicaudata the brown of the back is perhaps not quite so dull as it is in this form, a faint tinge of ochre-red showing in some lights.
Colours of soft parts. Iris hazel; legs, feet and bill black.
Measurements. This is the smallest of the three races; wing 75 to 85 mm., in one case 88 mm.; tail 77 to 81 mm.
Distribution. South Chin Hills and South Kachin Hills to Tenasserim, Arrakan and the whole of the Central Hills of Burma, Siam and Shan States. Andamans and Nicobars.
This form is another of the interesting cases in which birds from the two extremities of a range are nearer than they are to those in the centre. In India we have a horseshoe of which Assam and the Chin Hills may be said to form the centre, whilst Ceylon and the Malay Peninsula form the two extremities. Evolution has evidently gone on on similar lines with very similar results in the two latter places, though we need not infer from this that these extremities were ever linked together.
Nidification. Though there is little on record in regard to this form, its nests and eggs, habits of breeding, etc. seem to differ in no way from those of the Indian birds. In the South it lays two or three eggs, in the North three and more rarely four. A large series sent me by one of my collectors from Pegu are exactly like a series from Madras and measure on an average for forty eggs 20.0 X 15.9 mm.
The breeding season seems to be February to April but doubtless extends over a much longer period than this.
Habits. Takes the place in Burmese gardens, villages and towns of 0. e. emeria in Northern India etc and of the Madras bird in Southern India. It is not found in forest or any kind of heavy jungle.
