For further particulars respecting the habits of this beautiful species, we are indebted to observations made on birds that have been successfully reared in the Zoological Gardens of London and Amsterdam. A pair of Peacock Herons purchased in 1862 by the London Zoological Society, in 1865 showed symptoms of a desire to breed. According to Mr. Bartlett, whom we have to thank for the following interesting particulars, early in May they commenced carrying bits of grass, sticks, and such-like scraps, and were constantly walking round their pond, evidently in search of materials to compose a nest, and appeared to try to mix wet dirt with bits of moss. This proceeding suggested the idea of supplying them with wet clay and mud, which they at once employed. After a short time, they decided to make their nest on the top of a pole or tree about ten feet from the ground, on which was fixed an old straw nest. Both birds carried up mud and clay, mixed with bits of straw and grass-roots, in order to form the outer wall, and plastered the inside thickly with a coating of mud. Shortly after the nest was completed a broken egg was found, and in the early part of June another was laid; both parents took their turn in the work of incubation, and hatched the young bird on the 9th of July. It was covered with fine short down, and closely resembled a young Plover or Snipe in its general appearance. It remained in the nest, and was fed with small live fishes and insects, and did not gape or cry, but as soon as the parents appeared with food, it pecked the morsels from them, and swallowed them. It left the nest in twenty-one days, its wings being strong enough to bear it to the ground, where it was fed as before, and never returned to the nest; it grew very rapidly, and in two months' time was not distinguishable from the adults. Early in August the old birds began to repair the nest, adding a fresh lining of mud and clay; and at the end of the month the female laid another egg. This time the male attended more to the duties of incubation than his partner, who devoted her principal attention to feeding her now full-grown offspring. The second young bird was hatched on the 28th of September, but received such slight attention from its parents that the keeper feared it might starve from their neglect, and he therefore determined to go up by a ladder and feed it. The hungry little fellow took the food readily from his hand, and was thus reared till it arrived at maturity. * * * * *
