Finches are small to medium-sized, predominantly arboreal birds that have stout, conical bills ideally suited to cracking the seeds on which they rely for food. Mostly food is taken from the ground, although many species take large quantities on insect larvae from vegetation during the breeding season. Finches often boast quite colourful plumage, especially in the male, with bold markings that enhance flock cohesion.
 
There are 124 species worldwide. Nineteen species breed in Europe.
