Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Aves
Order: Passeriformes
Family: Fringillidae
Genus: Pyrrhula
Species: Pyrrhula pyrrhula

Geographic Range

Across Europe and Asia from the British Isles through Japan.

Biogeographic Regions:
palearctic (native ).

Habitat

Except for in Japan and Britain, where they inhabit deciduous woodland and cultivated grounds, Bulfinches are found in coniferous or mixed woodlands.

Terrestrial Biomes:
taiga ; forest .

Physical Description

The Bullfinch is a small bird, about six inches in length. The male has a distinctive black cap, rose-red underparts, and white rump. The female and juveniles are more pinkish-grey in color.

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

Bullfinches construct nests containing fine twigs with moss and lichen intertwined and a lining of black roots and shrubs. Nests are usually placed only a few feet above ground. There are sometimes up to three clutches of 4-5 eggs laid during the season, which spans early May to mid-July. Chicks hatch out in about two weeks and are fed a mixture of seeds and insects. The male Bullfinch helps the female incubate the eggs, andhe also feeds her while she sits on the nest. He later assists the female in collecting food for the young.

Key reproductive features:
iteroparous ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; oviparous .

Behavior

The Bullfinch can be seen throughout the year in pairs or in small family parties. In the spring, they also may form flocks of about fifty (rarely over one hundred) birds. Bullfinches generally are shy, perching within the cover of trees, not often on the ground. It reveals its presence through its penetrating low whistle "piping" song.

Key behaviors:
flies; motile .

Food Habits

Bullfinches feed primarily on buds and seeds. The buds from fruit trees, especially woodland trees, are eaten exclusively in the spring. A bullfinch feeds on the buds by landing on the tip of a branch and slowly moving towards the trunk, stripping the bud as it goes. However, it is only when supplies of seeds remaining from the previous summer and autumn diminish that bullfinches attack buds. In deciduous woods, bullfinches demonstrate a preference for the seeds of dock, nettles, privet, bramble, birch and ash. These seeds are the main food supply until buds begin to develop.

Economic Importance for Humans: Negative

Bullfinches inflict serious damage on orchards by feeding on the buds of fruit trees. This has been a serious problem, especially in south-east England, where orchards capable of yielding several tons of fruit have been stripped by bullfinches so efficiently that only a few pounds could be harvested.

Conservation Status

Only 1/3 of all clutches in woodland and 2/3 of those in farmlands live to adulthood. The remaining are eaten by predators, which are mainly jays, magpies, stoats, and weasels. The Bullfinch has been persecuted in England since the 16th century. Nevertheless, numbers continue increasing and more efficient ways of killing them are constantly being sought.
