(1823) Baza leuphotes burmana.

THE BURMESE BLACK-CRESTED BAZA.

Baza lophotes burmana W. L. Sclater. Bull. B. O. C, xli, p. 3, (1920) (Malewoon, Tenasserim). Baza lophotes. Blanf, and Oates, iii, p. 409 (part.).

Vernacular names. Dao-kwa Daoling (Cachari).

Description. Differs from the preceding bird in having less chestnut marking on the upper plumage and in having the band below the white breast almost wholly black.

Colours of soft parts as in the Indian form.

Measurements. Wing 221 to 246 mm.; tail 130 to 149 mm.; tarsus 25 to 30 mm.; culmen 20 to 23 mm. Sexes do not appear to differ in size in the Bazas.

Nestlings are covered with white down.

Young birds probably moult direct into the adult plumage. Two young birds said to have been taken from the nest and kept some weeks before being brought to me did not differ from the adults except, perhaps, in having more chestnut and white on the upper plumage.

Distribution. Assam South of the Brahmapootra, Burma, Siam, Indo-China and North Malay Peninsula.

Nidification. I took a nest of this Baza in Sylhet, South Assan, on the 22nd June containing two eggs, measuring 38.2 x 31.8 and 39.1 x 31.4 mm. In colour they are probably abnormal. They have the usual chalky grey-white ground but one egg has three fine blotches of red-brown at the larger end and the second has the smaller end stippled with pale reddish and a few small spots of lavender-grey at the larger end. The nest was in dense forest near some rice-fields and was just like that of the preceding bird. Hauxwell took three eggs from a similar nest on April the 30 th in the Thoungyin Valley. These were the normal white in colour.

Habits. Quite the same as those of the preceding bird. It is not rare in North Cachar but seems to keep to forests in the broken country and plains at the foot of the hills up to some 3,000 feet. The stomachs of the birds I examined contained masses of green caterpillars and grasshoppers.
