Hawfinch (Coccothraustes coccothraustes) (Linnaeus, 1758) Κοκκοθραύστης - Τζιεφαλόσπινος - Cyprus


The hawfinch (Coccothraustes coccothraustes) is a passerine bird in the finch family Fringillidae. Its closest living relatives are theevening 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 hawfinch is distributed in the whole of Europe, Eastern Asia (including North Japan), the North of Africa (Morocco, Tunisia and Argelia). It has also been sighted in Alaska, but this is reported as an accidental presence. It is not found in Iceland, parts of the British Isles, Scandinavia nor certain Mediterranean islands. It is however found in the South, such as in Spain and Bulgaria, as well as in central Europe, including parts of England and the South of Sweden. In Asia it can be found in the Caucasus, the North of Iran, Afghanistan, Turkistan, Siberia, Manchuria and North Korea.
The hawfinch typically inhabits deciduous forests during the spring to have offspring, often in trees that bear fruit, such as oak trees. They also incur into human areas, such as parks and gardens. They can also be found in pine woods, as long as there's a source of water in the vicinity. During autumn and winter they seek food-providing forests, especially those with cherry and plum trees. As for height, the hawfinch is present in any altitude up to that which is limited by the size of the trees.
The hawfinch is a shy species, and therefore difficult to observe and study. It spends most of the day on top of high branches, above all during breeding season. During the course of the hawfinch's life it can only be seen on the ground while looking for seeds or drinking water, always near trees. While drinking and eating it is fairly aggressive and dominant, towards both its same species or different ones, even bigger birds. It guards a quite small territory when chicks are born, however when not bearing any offspring it is known to guard entire woods. This is interpreted as an evolutionary advantage, given colony rearing is seen as safer against nest predators.From Wikipedia, the free encyclopedia
