929. Suya atrogularis khasiana

(929) Suya atrogularis khasiana.

Austen's Hill-Warbler.

Suya khasiana Godwin-Austen, A. M. N. H., (4) xviii, p. 412 (1876) (Shillong): Blanf. & Oates, i, p. 446.

Vernacular names. Daotisha dedao (Cachari).

Description. Differs from S. a. atrogularis in having the whole of the upper parts' light ferruginous-brown, brighter on the forehead : the moustachial white streak is generally broader.

Colours of soft parts as in S. a. atrogularis.

Measurements. Wing 49 to 53 mm.; tail 99 to 117 mm., tarsus about 22 nun ; culmen 11 to 12 mm.

Distribution. Assam, South and East of the Brahmaputra; Chin Hills.

Nidification. Austen's Hill-Warbler breeds in the Khasia Hills in even greater numbers than the Brown Hill-Warbler, and the nests and eggs of the two birds cannot be distinguished from one another. This bird, however, is more numerous above 4,000 feet than is S. c. assamica and less numerous below that height. The eggs, like those of S. a. atrogularis, are more often of the greenish type and the almost unicoloured pink type with a deep ring round the larger end is the least common type. Both of these birds are very frequently cuckolded by Cuculus canorus bakeri and by Caccomantis merulinus. The eggs of the latter agree very well with those of the foster-parent but the eggs of Cuculus are at least four times their bulk. The young bird when hatched soon outgrows the nest, which expands like a trellis-work round it until, finally, it bursts and the young Cuckoo is generally thrown on to the ground, where it is fed and looked after by the foster-parents.

Habits. Those of the genus. On the whole, both races of S. atrogularis affect rather thicker cover than do the races of S. crinigera, though neither will ever be found inside dense forest.
