Redpolls are small finches that are commonly found in the northern hemisphere. Synonyms for redpolls include arctic redpoll, hoary redpoll, lesser redpoll, and mealy redpoll. The arctic redpoll has a distinct white rump and is found in the tundra regions of the Arctic, while the hoary redpoll has a paler appearance and is often found in coniferous forests. The lesser redpoll is the smallest of the redpoll species and is found in temperate regions. The mealy redpoll is a larger redpoll species that is found in the subarctic and has a more streaked appearance. All redpoll species have a distinctive red cap, hence their common name.
