Bestimmung

The European greenfinch is 15 cm (5.9 in) long with a wingspan of 24.5 to 27.5 cm (9.6 to 10.8 in). It is similar in size and shape to a house sparrow, but is mainly green, with yellow in the wings and tail. The female and young birds are duller and have brown tones on the back. The bill is thick and conical. The song contains a lot of trilling twitters interspersed with wheezes, and the male has a "butterfly" display flight. Male greenfinch birds exhibit higher degrees of fluctuating asymmetry. The development of males' bones is more subject to disruption than that of females.

Taxonomie

The greenfinch was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae under the binomial name Loxia chloris. The specific epithet is from khloris, the Ancient Greek name for this bird, from khloros, "green".<p>The finch family, Fringillidae, is divided into two subfamilies, the Carduelinae, containing around 28 genera with 141 species and the Fringillinae containing a single genus, Fringilla, with four species. The finch family are all seed-eaters with stout conical bills. They have similar skull morphologies, nine large primaries, 12 tail feathers and no crop. In all species the female bird builds the nest, incubates the eggs and broods the young. Fringilline finches raise their young almost entirely on arthropods, while the cardueline finches raise their young on regurgitated seeds.<p>A molecular phylogenetic study published in 2012 found that the greenfinches are not closely related to other members of the genus Carduelis. They have therefore been placed in the resurrected genus Chloris that had originally been introduced by the French naturalist Georges Cuvier in 1800, with the European greenfinch as the type species.<p>There are 10 recognised subspecies.
