885. Acanthopneuste trochiloides davisoni

(885) Acanthopneuste trochiloides davisoni.

The Tenasserim White-tailed Willow-Warbler.

Acanthopneuste davisoni Oates, N. & Eggs of Ind. B., i, p. 269 (1889) (Muleyit), nom. nud.; Oates, Fauna B. I., i, p. 420 (descr.) (1889).

Vernacular names. None recorded.

Description. Differs from A. t. harterti in having the whole of the inner web of the outermost feather pure white and more white also in the next pair. It is darker and duller above, and has less yellow below.

Colours of soft parts as in A. t. trochiloides.

Measurements. Wing 47 to 52 (one, 55) mm.; tail 36 to 40 mm.; tarsus 16 mm.; culmen 8 to 9 mm.; 2nd primary between 9th and 10th.

Distribution. Breeding in the Burmese Hills from Karenni to Tenasserim. One specimen from Yunnan collected by Forrest has the whole inner web of the outermost tail-feathers white; it has the underparts also like those of davisoni and not the silky, rather oily-green white of claudiae. It is a December bird, and may possibly have wandered thus far. It may also extend to the Kachin Hills and Shan States.

Nidification. Nests and eggs taken in Tenasserim (Muleyit) by Davison in February and by my own collector in May were exactly like those of A. t. harterti. Other nests taken by Harington, Grant and Hopwood in the Bhamo Hills in April to July were also similar but I have seen no specimens from these Hills and they may be referable to harterti, though all three of these close observers are positive as to the identity of their birds with davisoni. The eggs are indistinguishable from those of the preceding bird. Like those they are more glossy and stout-shelled than any eggs of Munias, but less glossy, smooth and stout than those of the genus Seicercus.

Habits. Those of the species.
