|Species:|| carduelis carduelis|
The European goldfinch (carduelis carduelis) is a small passerine bird in the finch family.
In adults, back of head and nape of neck are black; the forehead and throat are red; the cheeks, lower neck, and underside are white; the back is a deep chestnut brown; the wings are black with a large yellow stripe; and the tail is black and white; legs are pinkish brown. It has a pointed, horn-coloured beak whose tip becomes black in winter. Juveniles are generally pale brown with some dark streaks or spots on the head, back, chest and flanks. The wings are similar to the adult's but have buff-brown feather tips instead of white on the coverts, tertials, and flight feathers. Juveniles molt into their red-face coloring during their first winter molt (August-September). 
Often seen in small flocks. Like other finches, it has an ondulating, fast flight.
BreedingEditThe European goldfinch breeds in spring. It nests in bushes and trees, often fairly high towards the end of the branch. The nest, which is built by the female, is a compact open cup situated between 2 and 10 metres above the ground. It is made of moss, rootlets, straw, lichens and plant downs. Interior is lined with wool, fur and feathers. The females then lays 5-6 bluish eggs with spots and streaks. Incubation lasts about 12 to 14 days by female alone. Females are fed by males during this period. At hatching, chicks are covered in with fairly long, thick, greyish down. They are fed insects and seeds. They fledge about 13 to 18 days after hatching, but they still depend on parents for some days more.
European Goldfinch produces two broods per season, often three. 
The European goldfinch feeds on seeds (especially thistle and sunflower seeds) and insects.
The call is a liquid 'tu-leep' or 'tsi-i-it'; also twittering song.
