THE PIED IMPERIAL PIGEON.
Myristicivora bicolor bicolor, Fauna B. I., Birds, 2nd ed. vol. v, p. 211.
There is nothing to add to the distribution of this Pigeon given in the ‘Fauna’ :—“Andamans and Nicobars through the Malay Peninsula to New Guinea. It has occurred on the coasts and islands of Burma from Sandoway in Arakan, where it was obtained by Hopwood in 1910. It visits constantly the islands off the Mergui coast and also in scanty numbers the coast itself and is said to breed regularly on all the islands. It also occurs, though irregularly, on the mainland of the West coast of Malay and more numerously on the islands.”
Wimberley obtained an egg of this Pigeon on Trinkut Island in the first week of February, but it was much addled and may have been laid long before, Davison failed to find it breeding, but quotes the natives to the effect that it lays in January, February and March.
Osmaston (B. B.) gives a good account of its breeding on South Sentinel Island (Journ. Bomb. Nat. Hist. Soc. vol. xviii, p. 201, 1908) ;—“South Sentinel is a coral island about a mile long by half a mile broad, about 17 miles N.-W. of the Little Andaman. The highest point of the island is only ah out 10 feet above high-tide level, and its centre is occupied by a swamp, the water of which is brackish.
“The whole island, with the exception of the swamp, is covered with dense forest, consisting mainly of Mohwa trees (Mimusops littoralis) with an undergrowth of various smaller trees and shrubs. There is a well-defined sea-fence along the shore, consisting of screw-pines (Pandamus sp.) and Hibiscus.
“In places the mohwa trees are of very large dimensions, but are hollow and evidently long past maturity.
"We found the island swarming with the Pied Imperial Pigeon (Myristicivora bicolor), and it was not long before we discovered a nest, containing a single fresh egg, followed by many others. Altogether we found some 50 nests containing each a single egg, some fresh, some more or less incubated.
“The nests were not as a rule close together. They were placed at the tops of small trees or on the lower branches of big ones, usually about 25 feet from the ground. One nest I found was only 10 feet from the ground, but this was exceptional.
“The nest is the usual flimsy platform of sticks, through which the egg is generally visible from below.
“The eggs are, of course, pure white, generally rather elongated ovals with a fair amount of gloss. The measurements are as follows :—
“Longest egg ..... 1.91" x 1.26" (=48.5 x 32.0 mm.).
"Shortest ..... 1.67" x 1.20" (=42.4 x 30.4 mm ).
“Mean of 28 eggs ..... 1.80" x 1.24" (=45.7 x 30.5 mm ),”
I make the measurements of thirty-four eggs, including most of those taken as above by Osmaston, to be as follows:—Average 44.2 x 31.2 mm. : maxima 48.3 x 31.5 and 47.3 x 33.2 mm. ; minima 41.3 x 29.6 mm.
