Cassell's book of birds; vol. 1

by Alfred Edmund Brehm

In North America and in Chili they attack the fruit before it is ripe, in search of the as yet milky pippins, and we may imagine the damage thus caused. According to Audubon, the cornstacks in the fields are sometimes the objects of their attack; they will hang upon them, and draw the ears out of the sheaves, thus sparing the owner the trouble of threshing. Some prefer one kind of seed and some another; but all agree in spoiling everything that man sows or plants for his own use; and on this account anything like friendship between the farmer and the parrots is quite out of the question.

After having satisfied their hunger in this manner they go in search of water to drink; and, according to Audubon and Schomburgk, do not refuse salt, or at any rate brackish water. Besides occasional rain-baths, they will bathe in lakes, washing themselves, Le Vaillant tells us, until they are soaked through, as with a heavy rain. We also learn from Audubon that they enjoy playing in the sand like fowls, covering their plumage with dust, and will creep into king-fishers' holes, in order to find it. They are fond of salt ground, and are always to be found near the saltworks in the forests.

The incubation of these birds takes place during the months that correspond in their native lands to our spring. The larger kinds appear to lay but once in the year, and then only two eggs; though the Australian Grass Parrot and some others are exceptions to this rule, inasmuch as they will lay regularly from three to four eggs, and in some cases from six to nine, twice or even three times during the year. The eggs are always white, smooth, and round. Holes in trees are the favourite nesting-places of these birds, but not exclusively so; some American kinds will lay in holes in the rocks, and the Indian parrots in crevices in old buildings, pagodas, monuments, or houses.

Audubon assures us that several females will lay in one hole; but we consider this as very doubtful, though it is true that parrots prefer breeding in society, sometimes even associated in immense flocks.

Molina speaks of a large settlement of these breeding birds in Chili, and Pöppig of another, probably of the same species. "These several settlements," says the last-mentioned naturalist, "must be very astonishing to those to whom they are new. Fancy yourself, about mid-day, wearily approaching a precipice, believing yourself to be perfectly alone, that deep silence reigning around you that always indicates noon in these tropical regions, when all animals seek repose in sleep; a kind of growling strikes your ear, but you look in vain for any creature that could produce it; suddenly you hear the parrots' cry of warning, answered by many others, and before you are awake to your true position, are surrounded by swarms of these quarrelsome birds, flying about in a close circle, and in evident anger, threatening to strike you. From all the innumerable holes upon the face of the rocks little round heads are protruding, looking comical enough; and those that do not come out unite their screams to the general uproar. Every opening indicates a breeding hole, that has been excavated by its owner in the clay met with between the strata of the rocks. At times many hundreds may be counted."

These colonies are always so cunningly situated, that it is impossible for a beast of prey to approach them. Such settlements could not be made in the woods, as the trees would not afford a foundation strong enough to sustain their weight.

In general, it is in old trees that parrots make their nests; in Central Africa the Adansonia is preferred, more especially should it grow on the outskirts of a forest. We once saw a group of monkey-bread trees in the Kordofanian steppes inhabited in this manner, although not yet covered with their leaves.

As it is not always possible to find a trunk whose interior has been hollowed by some friendly woodpecker, the parrots are often forced to excavate their own nesting-places, and then it is that they show what an available instrument their beak can be. It is the female who almost, but not exclusively, makes the hole; at this work she shows herself most skilful; she hangs, like a woodpecker, from the bark, and gnaws, rather than cuts away, one shred after another, until the dwelling is completed; this labour often occupies several weeks, but with patience the end is at length attained. The hole is the principal matter, the nest does not need much making; a few chips picked from the ground are all that is required as a bed on which to deposit the eggs; even a hole that leaves much to be desired in the way of convenience will content these very easily satisfied parents. "From the white stem of a Trimi-palm," says Pöppig, "I once saw a brilliant light blue tail depending; it betrayed the Yellow Arara, who was busy with her strong beak enlarging a woodpecker's hole, out of which her ell-long tail hangs whilst brooding." The female generally sits alone, and is fed and entertained by her mate during the whole time of incubation.

Among the smaller kinds of these birds, the brooding season lasts from eighteen to twenty, and with others nineteen, twenty-three, or twenty-five days.
