the other member of the group, which includes all the preceding birds, constitute a family by itself. This is the oil-bird, or _guacharo_, famous from Humboldt's description of the cave of Caripe in which they were first found. The young birds are covered with thick masses of yellow fat, for which they are killed in large numbers by the local peasantry. They live in caves wherever they are found, and only come out to feed at dusk. "Other birds which are sure to be observed even by the least ornithological traveller are the parrots and macaws, which fly in flocks from tree to tree of the forest, uttering their discordant cries. The macaws have blue and red or yellow plumage, but the parrots and parraquets are all wholly or mainly of a green hue. The several owls are naturally seldom seen, and, in the author's experience, rarely heard. "There are no less than thirty-two species of falcons or eagles known from Venezuela, and of these many are particularly handsome, such as the swallow-tailed kite and the harpy eagle of Guayana. Their loathsome carrion-eating cousins, the vultures, have four representatives. "In the rivers and caños of the lowlands there are abundant water-birds, and the identified species include a darter, two pelicans, several herons or _garzas_, the indiscriminate slaughter of which in the breeding season for egret plumes has been one of the disgraces of Venezuela, as well as storks and ibises. Among the most beautiful birds of these districts are the rosy, white or scarlet flamingoes, huge flocks of which are sometimes seen rising from the water's edge at the approach of a boat or canoe. There are also seven Venezuelan species of duck. "The various pigeons and doves possess no very notable characteristics, and one or two of the American quails are found in the Andes. Other game-birds include the fine-crested curassows of Guayana, the nearly allied guans and the pheasant-like hoatzin. There are several rails, and the finfeet are represented. The sun bittern is very common on the Orinoco. There are members of the following groups: the trumpeters (tamed in Brazil to protect poultry), plovers, terns, petrels, grebes, and, lastly, seven species of the flightless tinamous.
