It occurs almost anywhere where there are several trees, for it is not very choosy. In winter, the Chaffinch is a very common visitor to bird tables. Here it mostly makes do with gleaning seeds that have fallen to the ground. Since the females are a little smaller and therefore not so well adapted to winter conditions, they migrate further to the west and south than males. Therefore, in Switzerland and especially in Northern Europe, males predominate in winter. This may be the reason why the Common Chaffinch was given its scientific name Fringilla coelebs, the “bachelor finch”.
