THE ASSAM PALE-HEADED WOODPECKER.
Gecinulus grantia grantia, Fauna B. I., Birds, 2nd ed. vol iv, p. 27.
This Pale-headed Woodpecker is found from Eastern Nepal to Assam North and South of the Brahmapootra, Bengal East of the Bay, Manipur, Lushai and Chin Hills.
During the breeding season the present bird seems to be seldom found in evergreen forest, but haunts bamboo and scrub-jungle and prefers to all other cover both dense and thin secondary growth, more especially that which has grown up in deserted cultivation and in which dead trees and tree-stumps stand here and there among the bushes and other jungle. In such places they may be found from the plains up to about 3,000 feet or, occasionally, 1,000 feet higher.
For nesting purposes the Pale-headed Woodpecker selects a stump or tree-trunk in which the centre has completely rotted away, so that very little work is entailed in cutting out an entrance less than 2 inches across and seldom more than a few inches deep. The eggs are then laid in the natural chamber in the interior of the tree, which may be of any size or depth. Very rotten trees are sometimes chosen for nesting purposes and I have, more than once, been able to break away the wood round the tunnel with my fingers. This is never made at any great height from the ground, and those I have personally seen have been within 5 and 20 feet from it, while one taken by Hopwood in the Chin Hills was within 3 feet.
The birds lay in. April and May, less often in March, on the 21st of which month Hopwood obtained his nest. I have taken one nest on the 2nd July, but this was, I think, a second brood of a bird whose previous young had been taken by a snake or lizard. A pair, whose three eggs I took on the 14th April, laid three more by the 7th May in the same egg-chamber, but made a new entrance just below the old one. The birds return for several years in succession to the same tree for breeding purposes, for I have several times seen three entrances made to the same egg-chamber.
The full clutch seems to he almost invariably three.
Twenty-four eggs average 25.7 x 19.2 mm, : maxima 27.9 x 19.6 and 25.0 x 20.2 mm. ; minima 22.0 x 17.8 mm.
