1805. Astur badius poliopsis

(1805) Astur badius poliopsis.

HUME'S OF THE BURMESE SHIKRA.

Micronisus poliopsis Hume, Sir. Feath., ii. p. 325 (1874) (Thayetmyo). Astur badius. Blanf. & Oates, iii, p. 398 (part.).

Vernacular names. Shikra-sorai (Assam); Thane (Burm.).

Description. Rather larger than true A. b. badius but equally dark except on the head, which is a purer grey ; the sides of the head are concolorous with the crown instead of being tinged with brown or ashy as in both the Ceylon and Northern Indian Shikra; the underparts are much more richly marked with rufous than in any other race ; the tail seems proportionately rather longer and has only four dark bands on the lateral feathers (not including the outermost) instead of five or six.

Colours of soft parts as in other races.

Measurements. Wing, 186 to 203 mm., 221 to 226 mm.; culmen, 19 to 21 mm., 20 to 22 mm.

Distribution. Assam ; Burma, South to Tenasserim ; Siam and the Indo-Chinese countries to Formosa .

Nidification. Similar to that of the other races but the nest is often built on trees in quite thick forest. The few specimens I have seen were fiercely defended by both parents, who repeatedly stooped within a lew inches of the man climbing the tree. Twenty eggs average 39.0 x 31.8 mm.: maxima 41.0 x 31.0 and 40.0 x 32.1 mm.; minima 36.9 X 30.0 and 38.2 x 28.4 mm. The breeding-season in Assam is April and May ; in Burma March and April.

Habits. Those of the species except that this race is found more often in the interior of forests as well as in the open and round about villages.
