The common redpoll or mealy redpoll (Acanthis flammea) 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 common redpoll was listed in 1758 by Linnaeus in the 10th edition of his Systema Naturae under the binomial name Fringilla flammea. [2] [3] The current genus name Acanthis is from the Ancient Greek akanthis, a name for a small now-unidentifiable bird, and flammea is the Latin for "flame-coloured". [4]
The common redpoll was previously placed in the genus Carduelis . Molecular phylogenetic studies showed that the Arctic and common redpolls formed a distinct lineage, so the two species were grouped together in the resurrected genus Acanthis . [5] [6]
The nominate subspecies A. f. flammea, the mealy redpoll, breeds across the northern parts of North America and the Palearctic. There is also a subspecies that breeds in Iceland called the Icelandic redpoll (A. f. islandica), and one that breeds in Greenland and Baffin Island called the Greenland redpoll (A. f. rostrata). Many taxonomic authorities consider the lesser redpoll a subspecies of the common redpoll. [6] [7] Together, the Icelandic and Greenland forms are sometimes known as the 'northwestern redpolls'. All the subspecies migrate south into Canada, the northern U.S., or Eurasia. These birds are remarkably resistant to cold temperatures [8] and winter movements are mainly driven by the availability of food. There are two distinct populations (one lighter, one darker) united in islandica, the relationships of which are unresolved. [9]
The common redpoll is a small brownish-grey finch with dark streaks and a bright red patch on its forehead. It has a black bib and two pale stripes on the wings. Males often have their breasts suffused with red. It is smaller, browner and more streaked than the generally similar Arctic redpoll, adults measuring between 11.5 and 14 centimetres (4.5 and 5.5 in) in length and weighing between 12 and 16 grams (0.42 and 0.56 oz). Wingspan ranges from 7.5 to 8.7 in (19-22 cm). [10] The rump is streaked and there is a broad dark brown streak across the vent. It has brown legs, dark-tipped yellowish bills and dark brown irises. [11]
The mealy redpoll is larger and paler than the lesser redpoll with which it often mixes, apparently without significant interbreeding, though sympatry was established too recently to draw firm conclusions. [12] The male mealy redpolls are darker than the similarly sized Arctic redpolls, but the females are almost identical.
The range of the common redpoll extends through northern Europe and Asia to northern North America, Greenland and Iceland. It is a partial migrant, moving southward in late autumn and northward again in March and April. Its typical habitat is boreal forests of pines, spruces and larches. It feeds mainly on seeds, principally birch and alder seeds in the winter. [11]
The common redpoll builds its nest low down in a tree or bush. The nest has an outer layer of thin twigs, a middle layer of root fibres, fragments of juniper bark and lichens and an inner layer of down, willow buds and reindeer hair. Three to seven speckled eggs are laid and incubated by the female. They hatch after about 11 days and the young fledge in about a further 13 days. [11]
The northern wheatear or wheatear is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It is the most widespread member of the wheatear genus Oenanthe in Europe and North and Central Asia.
The ruddy turnstone is a small cosmopolitan wading bird, one of two species of turnstone in the genus Arenaria.
The common eider, also called St. Cuthbert's duck or Cuddy's duck, is a large sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. It can fly at speeds up to 113 km/h (70 mph).
The dunlin is a small wader, formerly sometimes separated with the other "stints" in the genus Erolia. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from dun, "dull brown", with the suffix -ling, meaning a person or thing with the given quality.
The Eurasian or common whimbrel, also known as the white-rumped whimbrel in North America, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific.
The black-tailed godwit is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, Limosa. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times.
The dark-eyed junco is a species of junco, a group of small, grayish New World sparrows. The species is common across much of temperate North America and in summer it ranges far into the Arctic. It is a variable species, much like the related fox sparrow, and its systematics are still not completely resolved.
The redpolls 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. The genus name Acanthis is from the Ancient Greek akanthis, a name for a small now-unidentifiable bird.
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 twite is a small brown passerine bird in the finch family Fringillidae.
The common linnet is a small passerine bird of the finch family, Fringillidae. It derives its common name and the scientific name, Linaria, from its fondness for hemp seeds and flax seeds—flax being the English name of the plant from which linen is made.
The Eurasian siskin is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Eurosiberia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.
The purple finch is a bird in the finch family, Fringillidae. It breeds in the northern United States, southern Canada, and the west coast of North America.
The Savannah sparrow is a small New World sparrow that is the only member of the genus Passerculus. It is a widespread and abundant species that occupies open grassland habitats in North America.
The vesper sparrow is a medium-sized New World sparrow. The only member of the genus Pooecetes, it is a pale sparrow with brown streaks that breeds across the grasslands of northern North America. It migrates to winter in the southern United States and Mexico.
The grey-capped greenfinch or Oriental greenfinch is a small passerine bird in the finch family Fringillidae that breeds in broadleaf and conifer woodlands of the East Palearctic.
The yellow canary is a small passerine bird in the finch family. It is a resident breeder in much of the western and central regions of southern Africa and has been introduced to Ascension and St Helena islands.
The brimstone canary or bully canary is a small passerine bird in the finch family. It is a resident breeder in central and southern Africa.
The gyrfalcon, the largest of the falcon species, is a bird of prey. The abbreviation gyr is also used. It breeds on Arctic coasts and tundra, and the islands of northern North America and the Eurosiberian region. It is mainly a resident there also, but some gyrfalcons disperse more widely after the breeding season, or in winter. Individual vagrancy can take birds for long distances. Its plumage varies with location, with birds being coloured from all-white to dark brown. These colour variations are called morphs. Like other falcons, it shows sexual dimorphism, with the female much larger than the male. For centuries, the gyrfalcon has been valued as a hunting bird. Typical prey includes the ptarmigan and waterfowl, which it may take in flight; it also takes fish and mammals.
