This race has a far more restricted area than the Northern one, being found only in Ceylon, Travancore and the Wynaad, a young bird having been obtained in the latter district.
So far as its nidification goes one has to rely almost entirely on Stewart’s notes on its breeding in Travancore. Dobson obtained two eggs in February 1929 near Talawakile from a nest about 50 feet up on the top of a jungle tree. Except for this no nests seem to have been taken other than those found by Stewart.
He describes the nests as well made but rather small structures of sticks lined sometimes with grass and roots, but always also with green leaves. These nests may be placed at any height from the ground between 20 and 60 feet, sometimes in quite small saplings and sometimes in huge forest trees. The nests are apparently never placed in the very small branches in the top of the tree, or close to it, but in the larger branches halfway up or rather more. The tree selected, whatever its size, is always in forest, and the birds undoubtedly prefer evergreen forest in very broken hills ; twice Stewart speaks of trees being chosen in or near ravines and more than once of the tree being near a stream and, whatever the forest may be, the birds evidently prefer open glades or spaces inside the forest, though in some instances the nests were found in deep forest with thick and tangled undergrowth.
The breeding season lasts from early February to the end of April, though few eggs seem to have been found after the first week of this latter month.
Either two or three eggs are laid, equally often two as three, and these cannot be distinguished from those of the Northern bird, though a big series of the latter would almost certainly average larger.
Thirty-two eggs of this form average 44.9 x 33.6 mm. ; maxima 46.4 x 36.2 and 46.3 x 88.1 mm. ; minima 41.1 x 35.9 and 42.0 x 85.0 mm.
