1214. Spizaetus kelaarti.
Spizaetus nipalensis, apud Layard, A. M. N. H. (2) xii, p. 98; Blyth, Ibis, 1866, p. 242, pt.; Hume, S. F. vii, p. 33. Spizaetus kelaarti, Legge, Ibis, 1878, p. 202 ; id. Birds Ceyl. p. 51, pl. 1. Limnaetus kelaarti, Hume, S. F. vii, p. 511; id. Cat.no. 36 bis.
This species is very closely allied to S. nepalensis, but adults are distinguished by being less dark, the feathers of the head having pale edges, by the malar and gular black stripes being much less developed, by the lower parts from the breast being paler brown, and especially by the white cross-bars on the feathers of the breast and abdomen extending right across the feathers and including the shafts. The feathering of the tarsus extends to the base of the middle toe. The feet are said by Legge to be more robust and the claws larger, the hind claw measuring in a straight line from base to point 2.1, whilst in S. nepalensis it never exceeds 1.9.
Young plumage imperfectly known : an immature male is brown above, the feathers with white edges, crown-feathers with broad buff margins; chin white unstriped, throat and fore-neck white with a few brown drops; breast and abdomen light brown with white cross-bars.
Length of female 31; tail 12.5; wing 19; tarsus 4.5 ; bill from gape 2.
Distribution. Mountains of Ceylon and Southern India. I find in the British Museum two skins, collected by Mr. Bourdillon at Mynall in Travancore, that agree perfectly with Legge's descrip¬tion, except that the claws are not larger than in Himalayan birds, and Hume has already suggested (S. F. x, p. 336) that a skin from the Nilgiris may also have belonged to S. kelaarti.
Habits, &c. Similar to those of S. nepalensis. Nidification unknown.
