THE CARDINAL.
Cardinals are remarkable for the extreme sweetness of their song, and, in my opinion, would far exceed the canary birds of our country, were they able to trill like them. From the shining purple of their feathers they have obtained the name of cardinals. The top of the head alone is adorned with a small black crest, like a little hat. They are about the size of a linnet. They fly in crowds to the most barren fields, where there are more thistles than grass, and are easily caught by boys, who will give you four or five cardinals in exchange for a single needle, in the city of Corrientes. I have seen cardinals resembling the rest in other respects, but much larger, being equal in size to a starling.
THE CHOPÌ.
The chopì, which is about the size of a swallow, and has dusky feathers, but if shone upon by the sun, of a blue colour, goes in flocks like European sparrows, flies up and down houses, and wheat fields, and delights the ear with its pleasing song. Some very small birds, the names of which I am unacquainted with, sing sweetly in gardens, but when taken they cannot long bear the confinement of a cage.
THE QUÎRAPÙ.
The quîrapù, a Guarany word, signifying the tinkling bird, so called because its voice is like the sound of a little bell, resembles a pigeon. It is of a grey colour, has very beautiful eyes, a large head, and a green throat, which is inflated when the bird cries. It never stays long in one place, but passes quickly from tree to tree; on which account it is very seldom, and with great difficulty, caught. Other birds of the same name, (quîrapù miri,) but smaller, and of a white colour mixed with dusky, fly in companies, and whilst one utters loud sounds, all the rest are silent.
THE TIÑINI.
The bird tiñini imitates the human voice, particularly at night, and not unfrequently alarms strangers sleeping in a wood, who take it for some enemy or spy.
THE TIJERAS.
This bird, which is smaller than our sparrow, and entirely white, is called by the Spaniards tijeras, the scissors, because it sometimes opens and shuts its tail, which consists of two long and very white feathers, like a pair of scissors.
