the rarest and most beautiful being the " curl-crested," whose head is covered with little glossy curls of a hard substance, more like quill or metallic shavings than feathers. These are at times plentiful, but did not appear till some weeks later than the other species, when I was at last rewarded for my patience by obtaining several beautiful specimens.
The common black vultures were abundant, but were rather put to it for food, being obliged to eat palm-fruits in the forest when they could find nothing else. Every morning it was an amusing sight to see them run after the pigs the moment they got up, three or four following close at the heels of each animal, for the purpose of devouring its dung the moment it was dropped. The pigs seemed to be very much annoyed at such indecent behaviour, and would frequently turn round and take a run at the birds, who would hop out of the way or fly a short distance, but immediately resume their positions as soon as the pig continued his walk.
I am convinced, from repeated observations, that the vultures depend entirely on sight, and not at all on smell, in seeking out their food. While skinning a bird, a dozen of them used to be always waiting attendance at a moderate distance. The moment I threw away a piece of meat they would all run up to seize it ; but it frequently happened to fall in a little hollow of the ground or among some grass, and then they would hop about, searching within a foot of it, and very often go away without finding it at all. A piece of stick or paper would bring them down just as rapidly, and after seeing what it was they would quietly go back to their former places. They always choose elevated stations, evidently to see what food they can discover ; and when soaring at an immense height in the air, they will descend into the forest where a cow has died or been killed, long before it becomes putrid or emits any strong smell. I have often wrapped a piece of half-putrid meat in paper and thrown it to them, and even then, after hopping up to it, they will retire quite satisfied that it is only paper, and nothing at all eatable.
Senhor B. had two fine sows, very fat, and each was expected to bring forth a litter of pigs in a few days. There were no pig-sties or sheds of any kind; and all animals retire into the forest on such occasions, and in a few days return with their young family, just as cats do with us. These sows had both
