[edit] Identification

L. 12-13 cm

Weight of 14 to 19 grams
Sexes similar

• Red face,
• Black and white head,

• Plain head
• Greyer back
• Unmistakable due to the yellow wing stripe.

On closer inspection male Goldfinches can often be distinguished by a larger red mask that spreads just beyond the eye.
Birds in central Asia (caniceps group) have a plain grey head behind the red face, lacking the black and white head pattern of European and western Asian birds.

[edit] Distribution

It breeds across Europe, north Africa, and western and central Asia, in open, partially wooded lowlands. It is resident in the milder west of its range, but migrates from colder regions. It will also make local movements, even in the west, to escape bad weather. It has been introduced to many areas of the world (Snow and Perrins 1998).

[edit] Taxonomy

The species is divided into two major groups, each comprising several races. The two groups intergrade at their boundary, so the caniceps group is not recognised as a distinct species despite its readily distinguishable plumage.

[edit] Habitat

Weedy fields, gardens.

[edit] Behaviour

[edit] Diet

The food is small seeds such as thistles (the Latin name is from carduus, thistle) and teasels, but insects are also taken when feeding young. It also regularly visits bird feeders in winter.

[edit] Breeding

They nest in the outer twigs of tall leafy trees, laying four to six eggs which hatch in 11-14 days.

In the winter they group together to form flocks of up to about 40 birds.
