(1817) Accipiter gularis nisoides.
THE INDO-CHINESE SPARROW-HAWK.
Accipiter nisoides Blyth, J. A. S. B., xvi, p. 727 (1847), Accipiter virgatus. Blanf. & Oates, iii, p. 404 (part.).
Vernacular names. None recorded.
Description. Similar to the Japanese Sparrow-Hawk hut darker, the male especially very dark, the lower plumage intensely rufous and the bars restricted to the flanks and even these often obsolete.
Colours of soft parts as in the other races.
Measurements. Wing, 156 to 165 mm., 182 to 194 mm. The male is curiously smaller than that of the other races and though the extreme measurements of the female are much the same, the average is decidedly smaller than in either A. g. gularis or A. g. stevensoni.
Distribution. Resident in South China from Fokhien, through the Indo-Chinese countries to Burma and the Andamans and South to the Malay States, Sumatra, etc.
Nidification. Similar to that of A. virgatus. Hopwood took nests, presumably of this Sparrow-Hawk, in South Tenasserim in April whilst Wickham and Osmaston found eggs from Pebruary to April in the Andamans. In the latter islands they were breeding in old nests of Crows in the avenues at Port Blair and Wickham found them very fierce and plucky in defending their eggs. Fourteen of these average 36.7 x 29.5 mm.: maxima 38.9 x 31.1 mm.; minima 33.2 x 28.0 mm.
Habits. Those of the genus. A forest-loving bird and but seldom seen though its shrill squeals sometimes reveal its presence.
