"The nest, which contained, to my great disappointment, five young birds about a week old, was very massively built, and completely choked up the hollow passage in which it was placed. The foundation consisted of a quantity of dry green moss, of the kind that natives bring in from the jungles in the rains, and sell for ornamenting flower vases, &c. Next came a thick layer of coir, mixed with a few dry skeleton-leaves and some short ends of old rope and a scrap or two of paper, and finally a substantial pad of blackish hair, principally human, but with cow- and horse-hair intermixed, forming a snug little bed for the young ones. The total depth of the nest exteriorly was at least 7 inches. "The bough, about 8 inches in diameter, was partly rotten and hollow the whole way down, having a small hole at the side above by which the birds entered, and another rather larger about a foot below the nest all choked up with moss that had fallen from the base of the nest. It is strange that it should have escaped my eye previously, as the tree overhung my gateway, through which I passed constantly during the day. Immediately below the nest a large black board bearing my name was nailed to the tree. "At Belgaum, on the 10th July, 1880, I observed a pair of Yellow Tits building in a crevice of a large banian tree about 9 feet from the ground. The two birds were flying to and from the nest in company, the hen carrying building-materials in her beak. I watched the nest constantly for several days, but never saw the birds near it again until the 18th inst., when the hen flew out of the hole as I passed the tree. I visited the spot on the 19th and 20th inst., tapping the tree loudly with a stick as I passed, but without any result, as the bird did not fly off the nest.
