Nidification. — Mr. Doig has recently found the Black Bittern breeding on the Eastern Narra in Sindh. 
The nests were placed in thickets, generally “ about 5 feet over the water, either in a dense tamarisk-bush or 
thick clump of reeds, and are about 9 inches in diameter and 3 inches in thickness, having a slight depression, 
in which the eggs, always four in number, are laid.” These are described as being “ broad ovals, sharp at 
both ends, and very nearly white in colour, but with faint suspicion of a delicate pale sea-green colour.” They 
vary in length from 15 to T85 inch, and in breadth from 1T5 to 13.
