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. 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.
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. The Bullfinch can be seen throughout the year in pairs or in small family parties. Bullfinches generally are shy, perching within the cover of trees, not often on the ground. Habitat Except for in Japan and Britain, where they inhabit deciduous woodland and cultivated grounds, Bulfinches are found in coniferous or mixed woodlands. The remaining are eaten by predators, which are mainly jays, magpies, stoats, and weasels.
