The chaffinch (Fringilla coelebs) is a small, easily recognisable passerine bird that is widespread in Europe. About the size of a sparrow (approximately 15 cm long and weighing 18 to 25 g), it particularly likes wooded areas, but also adapts well to parks, gardens and clearings. The male, with its colourful breeding plumage, has a brownish-grey back, a blue-grey cap and nape, a pinkish breast, very visible white wing bars and a greenish rump, while the female is more discreetly coloured, brown and beige. Its thick beak is adapted to its seed-eating diet, but the species becomes insectivorous during the breeding season. The chaffinch is also renowned for its powerful song, which can often be heard from February onwards.
Highly sociable outside the breeding season, it forms large winter flocks, sometimes mixed with other species. Its diet varies according to the season: it mainly eats tree seeds (beech, maple, birch, alder) and herbaceous plants, as well as insects, spiders and berries in spring and summer. The chaffinch builds an elaborate nest, often well hidden, made of moss and spider thread. Common and protected, it plays an important role in local biodiversity and is at the heart of many popular expressions, thanks in particular to its lively voice.
