The beautiful green jacamars, the puff-birds, and the bright-coloured woodpeckers are found all over Venezuela in the forests, but their relatives the toucans are among the most peculiar of the feathered tribe. With their enormous beaks and gaudy plumage they are easily recognised when seen, and can make a terrible din if a number of them collected together are disturbed, the individual cry being short and unmelodious. Several cuckoos are found in Venezuela, some having more or less dull plumage and being rare, while others with brighter feathers are gregarious. With the trogons, however, we come to the near relatives of the beautiful quezal, all medium-sized birds, with the characteristic metallic blue or green back and yellow or red breasts. The tiny, though equally beautiful, humming-birds are common sights in the forest, but a sharp eye is needed to detect them in their rapid flight through the dim light; some of the Venezuelan forms are large, however, notably the king humming-bird of Guayana; and the crested coquettes, though smaller, are still large enough to make their golden-green plumage conspicuous. The birds which perhaps most force themselves, not by sight but by sound, upon the notice of travellers are the night-jars; the “who are you?” is as well known in Trinidad as in Venezuela. The great wood night-jar of Guayana has a very peculiar mournful cry, particularly uncanny when heard in the moonlight. The kingfisher-like motmots have one representative in Venezuela, but 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.
