16-2-2025 POTRIES, VALENCIA - EUROPEAN GREENFINCH (Chloris chloris)

The European greenfinch, or simply greenfinch, is a small passerine bird belonging to the finch family Fringillidae. Exhibiting a predominantly green plumage with yellow accents on the wings and tail, the male is a vibrant sight, while the female and juveniles are more subdued with brownish tones. This bird measures approximately 15 cm in length with a wingspan ranging from 24.5 to 27.5 cm, resembling the size and shape of a house sparrow.

To identify the European greenfinch, look for its thick and conical bill, a characteristic of seed-eating birds. The male's plumage is a striking green with yellow flashes on the wings and tail, whereas the female and young birds are more muted with brownish backs. The male's display flight is akin to a butterfly, a dance to charm its mate.

The greenfinch favors woodland edges, farmland hedges, and gardens with dense vegetation for breeding. It nests in trees or bushes within these habitats.

This bird has a broad range across Europe, North Africa, and Southwest Asia. It is mainly sedentary, but some populations in the northernmost regions migrate southwards in colder months. The species has also been introduced to Australia, New Zealand, Uruguay, and Argentina.

The greenfinch is known for its social nature, often seen in flocks outside the breeding season. It exhibits a breeding season from March to June, with fledglings emerging in early July. The species is capable of producing multiple broods annually.

The song of the greenfinch is a delightful mix of trills and twitters, interspersed with distinctive wheezes, contributing to the rich tapestry of sounds in its natural environment.

The female greenfinch constructs the nest and incubates the eggs, typically laying 4-6 eggs per clutch. Eggs are incubated for about 13-14 days, with chicks being fed an insect larva-rich diet initially, followed by a seed paste as they grow.

The greenfinch can be confused with other finches, but its unique green and yellow plumage, along with its size and bill shape, usually set it apart.

Greenfinches have a varied diet consisting of seeds, berries, fruits, buds, flowers, and some arthropods. They forage in trees, bushes, and on the ground, adapting to available food sources.

The IUCN lists the European greenfinch as Least Concern, indicating a stable population despite some regional declines due to disease outbreaks.

3-5-2023 RIO SERPIS, GANDIA, VALENCIA - EUROPEAN GREENFINCH (Chloris chloris)

The European greenfinch or simply the greenfinch (Chloris chloris) is a small passerine bird in the finch family Fringillidae.

This bird is widespread throughout Europe, North Africa and Southwest Asia. It is mainly resident, but some northernmost populations migrate further south. The greenfinch has also been introduced into Australia, New Zealand, Uruguay, and Argentina.

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 bones of males may be more easily disrupted than that of females.

28-3-2023 SIERRA DE ANDUJAR, ANDALUCIA - EUROPEAN GREENFINCH (Chloris chloris)

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".

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.

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.
