Through such a forest, where the animal life was no less rich and varied than the vegetation, our boat glided slowly for hours. The number and variety of birds struck me with astonishment. The coarse sedgy grasses on either side were full of water birds, one of the most common of which was a small chestnut-brown wading bird, the Jacana (Parra), whose toes are immensely long in proportion to its size, enabling it to run upon the surface of the aquatic vegetation, as if it were solid ground. It was in the month of January, their breeding season, and at every turn of the boat we started them up in pairs. Their flat, open nests generally contained five flesh-colored eggs, streaked in zigzag with dark brown lines. The other waders were a snow-white heron, another ash-colored, smaller species, and a large white stork. The ash-colored herons were always in pairs, the white one always single, standing quiet and alone on the edge of the water, or half hidden in the green capim. The trees and bushes were full of small warbler-like birds, which it would be difficult to characterize separately. To the ordinary observer they might seem like the small birds of our woods; but there was one species among them which attracted my attention by its numbers, and also because it builds the most extraordinary nest, considering the size of the bird itself, that I have ever seen. It is known among the country people by two names, as the Pedreiro or the Forneiro, both names referring, as will be seen, to the nature of its habitation. This singular nest is built of clay, and is as hard as stone (_pedra_), while it has the form of the round mandioca oven (_forno_) in which the country people prepare their farinha, or flour, made from the mandioca root. It is about a foot in diameter, and stands edgewise upon a branch, or in the crotch of a tree. Among the smaller birds, I noticed bright Tanagers, and also a species resembling the Canary. Besides these, there were the wagtails, the black and white widow finches, the hang-nests, or Jape, as they are called here, with their pendent bag-like dwellings, and the familiar "Bem ti vi." Humming-birds, which we are always apt to associate with tropical vegetation, were very scarce. I saw but a few specimens. Thrushes and doves were more frequent, and I noticed also three or four kinds of woodpeckers. Of these latter there were countless numbers along our canoe path, flying overhead in dense crowds, and, at times, drowning every other sound in their high, noisy chatter.
