The hawfinch (Coccothraustes coccothraustes) is a passerine bird in the finch family Fringillidae. Its closest living relatives are the evening grosbeak (Hesperiphona vespertinus) from North America and the hooded grosbeak (Hesperiphona abeillei) from Central America especially Mexico. This bird breeds across Europe and temperate Asia. It is mainly resident in Europe, but many Asian birds migrate further south in the winter. It is a rare vagrant to the western islands of Alaska. Deciduous or mixed woodland, including parkland, with large trees – especially hornbeam – is favoured for breeding. The hawfinch builds its nest in a bush or tree, and lays 2-7 eggs. The food is mainly seeds and fruit kernels, especially those of cherries, which it cracks with its powerful bill. This large finch species is usually seen in a pair or small group. The 16.5–18 cm long hawfinch is a bulky bull-headed bird, which appears very short-tailed in flight. Its head is orange-brown with a black eyestripe and bib, and a massive bill, which is black in summer but paler in winter. The upper parts are dark brown and the underparts orange. The white wing bars and tail tip are striking in flight. The sexes are similar. The call is a hard chick. The song of this unobtrusive bird is quiet and mumbled.
The common chaffinch (Fringilla coelebs), usually known simply as the chaffinch, is a common and widespread small passerine bird in the finch family. The male is brightly coloured with a blue-grey cap and rust-red underparts. The female is much duller in colouring, but both sexes have two contrasting white wing bars and white sides to the tail. The male bird has a strong voice and sings from exposed perches to attract a mate. The chaffinch breeds in much of Europe, across Asia to Siberia and in northwest Africa. The female builds a nest with a deep cup in the fork of a tree. The clutch is typically four or five eggs, which hatch in about 13 days. The chicks fledge in around 14 days, but are fed by both adults for several weeks after leaving the nest. Outside the breeding season, chaffinches form flocks in open countryside and forage for seeds on the ground. During the breeding season, they forage on trees for invertebrates, especially caterpillars, and feed these to their young. They are partial migrants; birds breeding in warmer regions are sedentary, while those breeding in the colder northern areas of their range winter further south. The eggs and nestlings of the chaffinch are taken by a variety of mammalian and avian predators. Its large numbers and huge range mean that chaffinches are classed as of least concern by the International Union for Conservation of Nature.
