Canarie fanno un grande clamore quando si costruiscono i loro nidi. Una scatola di cartone è di solito dato loro con cotone e stringa per rivestimento; solitamente uno tira fuori che cosa gli altri mette in; ed essi entrambi industriously strappare la carta dal fondo della gabbia per aggiungere al loro materiale di costruzione. Infine, uno spostamento di posizione di un nido è completato e le uova sono previste. Ho

Canaries make a great fuss when building their nest. A pasteboard box is usually given them with cotton and string for lining; usually one pulls out what the other puts in; and they both industriously tear the paper from the bottom of the cage to add to their building material. Finally, a make-shift of a nest is completed and the eggs are laid. If the singer is a good husband, he helps incubate the eggs and feeds his mate and sings to her frequently; but often he is quite the reverse and abuses her abominably. The nest of the caged bird is very different in appear- ance from the neat nests of grass, plant down, and moss which the wild ancestors of these birds made in some safe retreat in the shrubs or ever- greens of the Canary Islands. The canary eggs are pale blue, marked with reddish-brown. The incubation period is 13 to 14 days. The young are as scrawny and ugly as most little birds and are fed upon food partially digested in the parents' stomachs. Their first plumage resem- bles that of the mother usually. In their wild state in the Canary and Azore Islands, the canaries are olive green above with golden yellow breasts. When the heat of spring begins, they move up the mountains to cooler levels and come down again in the winter. They may rear three or four broods on their way up the mountains, stopping at successive heights as the season advances, until finally they reach the high peaks. THE GOLDFINCH OR THISTLE BIRD.
