1738. Neohierax insignis cinereiceps

(1738) Neohierax insignis cinereiceps.

THE TENASSERIM HAWK.

Polihierax insignis cinereiceps Stuart Baker, Bull, B. O. C, xlvii, p. 101 (1927) (Myawadi). Poliohierax insignis. Blanf. & Oates, iii, p. 435 (part.).

Vernacular names. None recorded.

Description. Sex for sex similar to the preceding bird but with the back and upper parts darker, contrasting strongly with the head instead of merging into it. The lower parts are pure unstreaked white.

Colours of soft parts as in the Northern form.

Measurements. Wing, 139 to 145 mm., 143 to 147 mm.

Distribution. At present only known from Myawadi and the adjoining district in Tenasserim; extending Eastwards to Laos and French Indo-China.

Blanford considered this to be merely the fully adult stage of plumage acquired by P. i. insignis but I do not think this can be the case, as I have shown in my original description.

Nidification. Unknown.

Habits. Similar to those of the preceding race.
