The redpolls (genus Acanthis) (in Great Britain also historically known as redpoles) [2] [3] are a group of small passerine birds in the finch family Fringillidae, which have characteristic red markings on their heads. They are placed in the genus Acanthis. [4] [5] The genus name Acanthis is from the Ancient Greek akanthis, a name for a small now unidentifiable bird. [6]
All redpolls are northern breeding woodland species, associated with birch trees (although there are introduced populations in the southern hemisphere, New Zealand, and nearby subantarctic islands). They are small birds, brown or grey-brown above and with a red forehead patch. The adult male's breast is washed in red, but in females and young birds, the buff breast and white belly are streaked with brown. The bill is small and yellow. Some birds, particularly young ones, are difficult to assign to species.
They are primarily seed-eaters, and often feed acrobatically like a tit; their diet may include some insects in summer. They have a dry reeling song and a metallic call. They lay four to seven eggs in a nest in a tree or, in the case of the Arctic redpoll, a large bush. They can form large flocks outside the breeding season, sometimes mixed with other finches.
The taxonomy of redpolls is unsettled, with several different very closely related [7] forms of redpolls which have been considered as anything from one to five species. [8] Some studies [9] [10] favour three species, but this is certainly not definite. Global lists currently support either two species (the common and hoary redpoll) [11] or a single species (the common redpoll). [12] Most recently, genome-wide analyses found differences in gene expression but no genetic divergence, suggesting that plumage forms have originated recently, within a single interbreeding lineage, and do not represent species boundaries. [13]

The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches generally have stout conical bills adapted for eating seeds and nuts 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 native distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes the canaries, siskins, redpolls, serins, grosbeaks and euphonias, as well as the morphologically divergent Hawaiian honeycreepers.
Serinus is a genus of small birds in the finch family Fringillidae found in West Asia, Europe and Africa. The birds usually have some yellow in their plumage. The genus was introduced in 1816 by the German naturalist Carl Ludwig Koch. Its name is Neo-Latin for "canary-yellow".
The genus Carduelis is a group of birds in the finch family Fringillidae.
The rosefinches are a genus, Carpodacus, of passerine birds in the finch family Fringillidae. Most are called "rosefinches" and as the word implies, have various shades of red in their plumage. The common rosefinch is frequently called the "rosefinch". The genus name is from the Ancient Greek terms karpos, "fruit", and dakno, "to bite".
The common redpoll or mealy redpoll is a species of bird in the finch family. It breeds somewhat further south than the Arctic redpoll, also in habitats with thickets or shrubs.
The Arctic redpoll or hoary redpoll is a bird species in the finch family Fringillidae. It breeds in tundra birch forest. It has two subspecies, A. h. hornemanni of Greenland and neighbouring parts of Canada, and A. h. exilipes, which breeds in the tundra of northern North America and the Palearctic. Many birds remain in the far north; some birds migrate short distances south in winter, sometimes travelling with common redpolls.
The lesser redpoll 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 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 mountain finches are birds in the genus Leucosticte from the true finch family, Fringillidae. This genus also includes the rosy finches, named from their pinkish plumage.
The citril finch, also known as the Alpine citril finch, is a small songbird, a member of the true finch family, Fringillidae.
The Corsican finch, also known as the Corsican citril finch or Mediterranean citril finch, is a bird in the true finch family, Fringillidae.
The oriole finch is a small passerine bird in the finch family. It is found in Africa and is native to Burundi, Cameroon, Democratic Republic of the Congo, Equatorial Guinea, Kenya, Malawi, Nigeria, Rwanda, South Sudan, Tanzania and Uganda. It lives in subtropical or tropical moist evergreen montane forests.
The genus Rhynchostruthus is a small group of finches in the family Fringillinae. Commonly known as golden-winged grosbeaks, they are attractive, chunky, medium-sized, robust-billed songbirds restricted to the southern Arabian and northern Somalian regions.
The Warsangli linnet is a species of finch in the family Fringillidae. It is found only in northeastern Somalia. Its natural habitats are subtropical or tropical dry forest and subtropical or tropical high-altitude shrubland. It is threatened by habitat loss.
The Vietnamese greenfinch is a small passerine bird in the family Fringillidae. It is found only in Đà Lạt Plateau of southern Vietnam. Its natural habitat is open montane pine forest and scrubland. It is threatened by habitat loss.
The yellow-breasted greenfinch is a small passerine bird in the family Fringillidae that is native to the northern regions of the Indian subcontinent.
The Yemen linnet is a species of finch in the family Fringillidae. It is found in Saudi Arabia and Yemen. Its natural habitat is subtropical or tropical dry shrubland.
Blanford's rosefinch or the crimson rosefinch, is a species of finch in the family Fringillidae. It is found in Bhutan, China, India, and Nepal. Its natural habitat is boreal forest.
The greenfinches are small passerine birds in the genus Chloris in the subfamily Carduelinae within the Fringillidae. The species have a Eurasian distribution except for the European greenfinch, which also occurs in North Africa.
Spinus is a genus of passerine birds in the finch family. It contains the North and South American siskins and goldfinches, as well as two Old World species.
Linaria is a genus of small passerine birds in the finch family (Fringillidae) that contains the twite and the linnets. The genus name linaria is the Latin for a linen-weaver, from linum, "flax".
