559. Copsychus saularis musicus

(559) Copsychus saularis musicus.

The Malay Magpie-Robin.

Lanius musicus Raffles,Trans. Lin. Soc, xii, p. 147 (1820) (Sumatra).

Vernacular names. Thapate-Iway (Burin.).

Description.— Adult male. Differs from the Indian form in having the outer tail-feathers broadly marked with black and the fourth pair wholly black; the under wing-coverts wholly or largely black. Both male and female frequently have the posterior abdomen much infuscated.

Colours of soft parts as in the Indian Magpie-Robin.

Measurements. Wing 93 to 104 mm.; tail 85 to 92 mm.; culmen 19 to 20 mm.

Distribution. The extreme South of Peninsular Burma, South of Siam, Malay Peninsula to Java, Sumatra and Borneo.

The Tenasserim bird is, as might be expected, somewhat intermediate but many specimens from the extreme South seem nearer to the Sumatran than to the Indian form, so it seems necessary to accept this former race as occurring within the limits of this work.

Nidification. Similar to that of the Indian bird. A series of eggs collected by Messrs. W. J. 0. Williamson and E. G. Herbert are not distinguishable from those of that bird. Fifty average 22.5 x 16.7 rain, and the extremes are 29.1 x 18.1, 23.0 x 18.3 mm. and 19.5 x 15.9 mm.

Two clutches taken by Mr. E. Gr. Herbert are a brilliant pale blue in colour with sparse and tiny specks of dark brown.

They breed in April, May and June in Siam and the Malay Peninsula, but in Borneo Mr. J. 0. Moulton took eggs in the middle of March.

Habits. These differ in no way from those of the other subspecies. According to Davison this race does not ascend the hills to any height, and it is also more essentially a ground-bird than is the Indian form.
