The lesser redpoll (Acanthis cabaret) is a small passerine bird in the finch family, Fringillidae. It is the smallest, brownest, and most streaked of the redpolls. It is sometimes classified as a subspecies of the common redpoll (Acanthis flammea) but has recently been split from that species by most taxonomies including Clements and the British Ornithologists' Union. It is native to Europe and has been introduced to New Zealand. Many birds migrate further south in winter, but the mild climate means that it can be found all year round in much of its range, and may be joined by the other two redpoll species in winter. The commonest call is a harsh, metallic, staccato chuch-uch-uch-uch given in flight or while perched. It also has a plaintive alarm call. The trilling song combines the flight call with a buzzing rattle and is often given in an undulating song-flight around the territory. (Source: Wikipedia.org, CC BY-SA)
