Chaffinches are small, plump songbirds, also known by their scientific name Fringilla coelebs. There are several synonyms for chaffinches, depending on the region they are being referred to. In North America, they are sometimes called European chaffinches to differentiate them from the native American species of finches. In some areas of the UK, they are known as "pink finches" due to the pinkish hue on their plumage. Other common synonyms include "red breasts" because of the bright color on their chests and "humberhawks" because of their habit of perching high up in trees. All of these synonyms refer to the same bird species, and their preferred names may vary depending on location and culture.
