A Chaffinch
Chaffinches often have two broods in a year, and each clutch comprises 4 to 6 brownish eggs, which the female incubates on her own for 12 to 13 days. The birds do much damage to fruit trees in the spring by eating flower buds, although they also feed on seeds and insects. Many migrate to southern or western Europe during the winter. The sexes migrate from some areas in separate flocks. Young male chaffinches learn the song of adults near them, and the songs of birds from different locations are distinguishable. Another species sometimes called chaffinch is the teydefinch, or blue chaffinch, of the Canary Islands.
