The creolla is no doubt the descendant of the fowl originally introduced about three centuries ago by the first colonists in La Plata, and has probably not only been uncrossed with any other improved variety, such as are now fast taking its place, and has lived a much freer life than is usual with the fowl in Europe. It is a rather small, lean, extremely active bird, lays about a dozen eggs, and hatches them all, and is of a yellowish red colour--a hue which is common, I believe, in the old barn-door fowl of England. The creolla fowl is strong on the wing, and much more carnivorous and rapacious in habits than other breeds; mice, frogs, and small snakes are eagerly hunted and devoured by it. At my home on the pampas a number of these fowls were kept, and were allowed to range freely about the plantation, which was large, and the adjacent grounds, where there were thickets of giant cardoon thistle, red-weed, thorn apple, &c. They always nested at a distance from the house, and it was almost impossible ever to find their eggs, on account of the extreme circumspection they observed in going to and from their nests; and when they succeeded in escaping foxes, skunks, weasels, and opossums, which, strange to say, they often did, they would rear their chickens away out of sight and hearing of the house, and only bring them home when winter deprived them of their leafy covering and made food scarce. During the summer, in my rambles about the plantation, T would occasionally surprise one of these half-wild hens with her brood; her distracted screams and motions would then cause her chicks to scatter and vanish in all directions, and, until the supposed danger was past, they would lie as close and well-concealed as young partridges. These fowls in summer always lived in small parties, each party composed of one cock and as many hens as he could collect--usually three or four. Each family occupied its own feeding ground, where it would pass a greater portion of each day. The hen would nest at a considerable distance from the feeding ground, sometimes as far as four or five hundred yards away. After laying an egg she would quit the nest, not walking from it as other fowls do, but flying, the flight extending to a distance of from fifteen to about fifty yards; after which, still keeping silence, she would walk or run, until, arrived at the feeding ground, she would begin to cackle. At once the cock, if within hearing, would utter a responsive cackle, whereupon she would run to him and cackle no more. Frequently the cackling call-note would not be uttered more than two or three times, sometimes only once, and in a much lower tone than in fowls of other breeds.
