It takes 105 days for a complete molt. Their song is musical, loose and disjointed. They use vocalizations and visual cues to communicate. These birds do considerable damage to California orchards of peaches, apricots, plums, cherries and nectarines.
These birds are monogamous, with one mate through each nesting. The male defends the nesting territory. The female builds the nest, incubates and broods the young. The nest is usually 5 - 7 feet above the ground in a bush, tree, cactus or building. It is open and cuplike and made of grasses, plant stems, leaves, stems, twigs, hair, string, cotton and wool. They will occasionally use old nests of other birds. Four or five blue-green spotted eggs are laid anytime from February to August. Incubation is 12 - 16 days. The young can leave the nest 11 - 19 days after hatching.
"Carpodacus" is Greek for "fruit-eater." This bird has been introduced in Hawaii and is established on all of the main islands. Color has changed to yellow, red and orange.
Members of the finch family are protected by the Migratory Bird Treaty Act and may not be kept in captivity without a permit. In the 1940's an illegal shipment of house finches, for the cagebird trade, was intercepted in New York City. The birds were released on Long Island and established a small breeding enclave that struggled for several years to survive. Since then, they have spread all along the Atlantic seaboard.
