Finch

Finch

The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include: the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the American sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Finches and canaries were used in the UK, Canada and USA in the coal mining industry, to detect carbon monoxide from the eighteenth to twentieth century. This practice ceased in the UK in 1986.
