The Yellow Bittern is not very common in Sind; it occurs also in Guzerat, but is rare in the Deccan. Captain Butler found it breeding at Milana, about 18 miles east of Deesa. The nest, composed of sedges, was built in a dense clump of bulrushes. The eggs, three in number, were of a pale skim-milk blue color and were about 1.25 inches in length.
