Morphological characteristics

All Finches have 12 remiges and 9 rector feathers. The basic colors of the plumage are brown and greenish; many species also have large areas of black color, while white is generally absent, except for some bands on the wings and other similar distinctive signs. Bright yellow and red carotenoid pigments are very common in this family, and so the blue structural colors are quite rare, as yellow pigments turn blue into green. Many species have a marked sexual dichromatism: females usually lack the bright plumage of males.

Biology

They generally live in well-forested areas, but some even go to the mountains or even to deserts. They are mainly granivores. During nesting, however, the Finches also feed on small arthropods. They have lively flight like almost all the small passerines, alternating fast beats dala with glides made with closed wings. They are all excellent singers and many of them have become common aviary birds; among these, the most famous is the domestic canary (Serinus canaria domestica). The nests are basket-shaped and are usually built on trees or, more rarely, between bushes and rocks.
