The young are perfectly helpless when they leave the egg, but their growth and development is rapid. At first they are very imperfectly fledged, but in from five to six days the feathers begin to sprout, and they open their eyes within eight or ten days of their birth. The warbling Grass Parrakeet leaves the nest thirty-three days after being hatched, and may be seen flying about two days later. Both parents feed the young and tend them for some time after they have left the nest.

The food, if corn, is softened in the parent's crop before it is put into the beak of the young bird. Schomburgk tells us that a pair of parrots which had settled near his encampment in the wood, only fed their young twice in the day, once at eleven in the forenoon and again about five in the evening. As soon as they arrived they perched upon a branch near the hole, and if they fancied themselves watched would sit quite still, until they thought that a favourable opportunity occurred for stealing in unobserved.

The parents are by no means deficient in tender care for their progeny, and will shield their offspring from danger with most self-sacrificing courage. Some species will attach themselves with great tenderness to deserted birds; not merely to those of their own family, but to any helpless orphan, even although belonging to another species.

Cunningham tells us that the surgeon of the Triton—a ship plying between England and Australia—had a Blue Mountain Parrot, and a very beautiful smaller one, that he had taken from its nest so young that it was unable to feed itself. Under these circumstances the elder bird undertook to give it food, and watched over it with the greatest anxiety. The mutual friendship of these creatures seemed to increase as time went on; most part of the day was spent in caresses; they trimmed each other's feathers, and the old bird would spread her wings over her little charge with every indication of solicitude. Indeed, their affectionate demonstrations soon became so noisy that they had to be separated, in order that the passengers might not be annoyed, and the young one was placed in a cabin with several others.

After a two months' separation the elder parrot succeeded in escaping, and was guided to the cabin by the voice of its young protégé, to whose cage it clung. From this time the friends were not parted, but a fortnight later the young one died, in consequence of a wound caused by a fall. Its friend was silent from that hour, and did not long survive its little charge.

Parrots attain their full beauty of plumage, and commence laying by the time they are two years old; some of the smaller kinds breed within the first twelve months, but, notwithstanding this, live for many years, and have been known to long survive the family in which they passed their youth.

In countries where parrots abound they are destroyed with unrelenting perseverance, and this simply for the protection of property. "People must not imagine," says Audubon, "that all the injuries they are guilty of meet with no reprisals; on the contrary, these birds are slaughtered in great numbers during their predatory visits to the farmers. Armed with his loaded gun, the exasperated proprietor creeps amongst them, and brings down eight or ten at the first shot; the survivors rise screaming into the air, fly about in circles for three or four minutes, but return, and surround the bodies of their fallen companions, uttering loud cries, and this is repeated again and again, until so few remain that the farmer does not think it worth while to waste his powder and shot upon them. Hundreds are thus destroyed in the course of a few hours, and baskets filled with the spoils."

Various are the expedients adopted for their destruction in different parts of the world. The Chilians rush out with all speed when they see the parrots settling, and attack them with sticks. The Australians rouse them from their sleeping-place, and then throw their boomerangs amongst the retreating flock. Adventurous men let themselves down the rocks in which the South American species breed, to draw the young out of their holes with hooks; or shooting parties and hunters endeavour to steal upon them unawares. When it is found impossible to climb the trees on which they breed, these are cut down, and nets and limed twigs placed around to catch the young. The flesh of the slaughtered birds is often eaten, although hard and tough, or is made into excellent soup.

Very frequently they are sought for on account of their splendid plumage. "There is nothing more natural," says the Prince von Wied, "than this most simple and pleasing decoration, to the use of which savages are much addicted; and very beautiful are the articles made from feathers by entirely untaught tribes; many of the aborigines of Brazil particularly excelled in this kind of work." The love for parrot feathers is very ancient. "In long forgotten times," says Pöppig, "the inhabitants of the tropical forests brought arara feathers as tribute to the Incas, for the decoration of their palaces, and early historians inform us that these feathers and the 'Koka' were the only produce which led to the peopling and cultivation of the formidably hot districts in which they abound."
