Other species articulate some words so clearly, that they receive their names from the sentences they utter. One cries "Who are you? who, who, who are you?" Another bids you "Work away; work, work away." A third shrieks mournfully--"Willy come, go Willy, Willy, Willy come, go;" and a fourth exclaims--"Whip poor Willy; whip, whip, whip poor Willy!" Happily for it, neither the negro nor the Indian--who believe it to be a bird of ill-omen--will venture to kill it; supposing the bird to be the receptacle for departed souls, come back to earth, unable to rest for crimes done in their days of nature. Ignorance alone has given the goatsucker its name. When the moon shines bright, it may be seen close by the cows, goats, and sheep, jumping up every now and then under their bellies. "Approach a little nearer," says Waterton; "he is not shy, he fears no danger, for he knows no sin. See how the nocturnal flies are tormenting the herd, and with what dexterity he springs up and catches them as fast as they alight on the bellies, legs, or udders of the animals! Observe how quiet they stand, and how sensible they seem of his good offices; for they neither strike at him, hit him with their tails, tread on him, nor try to drive him away as an uncivil intruder. Were you to dissect him, and inspect his stomach, you would find no milk there. It is full of the flies which have been annoying the herd." CACIQUES. A species of cacique--of which there are several--like the blue jay of the northern part of the continent, is celebrated for its imitative powers. It is one of the handsomest in form of the feathered tribe, in size somewhat larger than a starling. On each wing it has a yellow spot; and its rump, belly, and half the tail are of the same colour. All the rest of the body is black; while the beak is of the colour of sulphur. It lives on the fruits and seeds which nature has provided in the forest; but wherever human habitations are found, it delights to take _up_ its station on a tree close by, and there, for hours together, pour forth a succession of imitative notes. Its own song is sweet, but very short. If a toucan is yelping in the neighbourhood, it drops its own note and imitates the huge-beaked bird. Then it will amuse itself with the cries of different species of woodpeckers; and when the sheep bleat, it will distinctly answer them. Then comes its own song again; and if a puppy-dog or a Guinea-fowl interrupt it, it takes them off admirably,-- and by its different gestures during the time, it might be supposed that it enjoys the sport.
