It is necessary to be personally acquainted with these lovable little creatures, and to have observed them during the performance of their parental duties, to be able to understand the enthusiasm with which they are regarded; it is only during their pairing time that we become fully conscious of their many merits. "The male," says Devon, "is a model husband, and his mate is a model mother. He devotes his whole attention to his chosen one, never heeding another female, though she be in the same place with him; he is always zealous, devoted, and ardent--indeed, shows the utmost affection towards his partner. Perched upon a twig before the opening of the nest, he sings her his best song, and while she is sitting feeds her with as much zeal as pleasure. He is neither dull, quiet, nor sleepy, like many other husbands, but always cheerful and charming." The building of the nest is the exclusive business of the female. She works with her beak at the entrance till it satisfies her, and then, more or less, at the interior, gnawing off little shreds, on which she lays, in the space of two days, from four to eight small, round, shining white eggs. She then sits for eighteen or twenty days most assiduously, and during the whole time is fed by the male, never leaving the hole except on the most urgent necessity. The young remain some thirty or thirty-five days in the nest, and only quit it when fledged. During all this time the mother is busily occupied in keeping their home clean, and, like a good housewife, clears out her little chamber every morning, and cleanses and purifies her offspring with extraordinary care. Immediately after leaving the nest, the young go in search of food, and a few days after conduct themselves quite like the old birds. Still, care must be taken, for the before-mentioned zeal of the father is often shown in an unexpected manner; he will fall upon his brood so boisterously, and seize them with so much roughness, that he kills them by his caresses. The first brood is no sooner fledged than the parents have a second, and even a third and fourth; indeed, Schlegel, the director of the Zoological Gardens at Breslau, declares that he has known them breed all the year round. Such cases are exceptional; three broods, according to our own observations, are the usual number. The last family of young may be left with the parents without danger, and then the first brood may be brought back. These show themselves to be quite as affectionate as their parents, and feed and take care of the nestlings. Moreover, they will imitate each other in everything--in climbing, flying, eating, and chattering--so that the noise in the nursery often becomes quite deafening, and sometimes seems to be too much even for the parents, who will then remove to a distance to get out of the way.
