Redpoll Challenge: 4 subspecies. Ron Pittaway : Posted to Ontbirds and ID-Frontiers on 18 December 2007 : Redpoll Challenge in 2007: This is a major redpoll winter in southern Canada and the northern United States. The legendary George North of Hamilton once saw all four North American redpoll subspecies (races) in the same flock on 23 March 1958 (Curry 2006).
A.f. rostrata or Greenland Redpoll breeds in NE Canada, W and SE Greenland and Iceland. It winters in E Canada, NE USA, Iceland and NW British Islands. This race is larger than nominate, with larger bill and longer wings. The upperparts are browner and heavily streaked, the rump may be …
rostrata), which is another winter visitor and is larger than the Common Redpoll and darker than the Lesser Redpoll. The final type is the Arctic Redpoll ( C. hornemanni ), which is a rare vagrant from Greenland and Lapland and is slightly larger than the 'Greenland Redpoll' and has a white rump and underparts. Common/Mealy Redpoll Acanthis flammea flammea-> N Europe, Siberia, Alaska and Canada Common/Mealy Redpoll Acanthis flammea rostrata (incl. ssp. islandica)-> NE Canada, Greenland, Iceland. Object of study: Vocalizations and plumage variability. Please send photos if you have a redpoll you’re not sure of what species it is.

A.f. rostrata or Greenland Redpoll breeds in NE Canada, W and SE Greenland and Iceland. It winters in E Canada, NE USA, Iceland and NW British Islands. This race is larger than nominate, with larger bill and longer wings. The pale phenotype from Iceland is the most distinct redpoll on that island, and might deserve a new name; the name islandica should be restricted to the dark, rostrata-like birds. The third type is the 'Greenland Redpoll' (C.

"Greater" Common Redpoll (rostrata): This large and dark subspecies breeds on Baffin Island and Greenland. Greater Redpolls are a winter visitor in small numbers to the southern parts of eastern Canada from Ontario to Newfoundland (Godfrey 1986) and to the northeastern United States.
(species): Acanthis flammea flammea (mealy redpoll) - nominate subspecies; Acanthis flammea icelandica (Icelandic redpoll), Acanthis flammea rostrata (Greenland redpoll), Acanthis flammea cabaret (lesser redpoll) - other subspecies; Translations . See Acanthis flammea at Avibase; References . Acanthis flammea on Wikipedia. Wikipedia I thought it was so cool to see this subspecies "Greenland/Greater" Common Redpoll (rostrata/icelandica) in a tree foraging on the Japanese Black Pine cones.
The bird possessed some rather Arctic Redpoll-like structural characters, largely a function of feather density - a fat ‘pug-faced’, small-eyed look, bull-necked appearance, deep chest, broad ‘shoulders’, very long ‘tubular’, barrel-shaped body (like the rostrata), heavily ‘trousered’ tibia and long wings and tail.

27 Aug 2014 Ross had shown calves at his local Whittlesea Show in calf rearing competitions and from here came his desire to show Stud Red Poll cattle.

M Bredmar, Landsort, Södermanland, ringed (F 2007:148, F 2013:150) The first of these taxa included several putative 'Greater' Common Redpolls Acanthis flammea rostrata, a sub-species breeding in Baffin Island, Southern Greenland, and Northern Iceland. 'Greater' Redpolls can apparently be found wintering in the Eastern US in incursion years and the handful that I noted were not at all easy to pick out from the hundreds of nervous redpolls within the main flock. The most familiar Common Redpoll (Acanthis flammea) subspecies across the circumpolar areas of the globe including North America and Eurasia is the “flammea.” subspecies. There’s also the “Greater” Common Redpoll, also known as the “rostrata” subspecies, which is endemic to Greenland. Fringillidae.

It is sometimes referred to the Common Redpoll (large-billed). This redpoll has a darker plumage and is the larger of the two. It breeds mainly in Greenland.

The most widely held view recognises two species, the common redpoll (including flammea, islandica, rostrata and cabaret) and the arctic redpoll (including hornemanni and exilipes).
A summary of redpoll subspecies.
The variation is stunning and observing these birds is nothing but fascinating. I managed to live more than a year in Mongolia before seeing a single Redpoll. The pale phenotype from Iceland is the most distinct Redpoll on that island, and might deserve a new name; the name islandica should be restricted to the dark, rostrata-like birds. Current taxonomic arrangements of Redpolls in two polytypic species are rather poorly founded, because most similarities in morphological criteria may be the result of convergent evolution. Greenland Redpoll (rostrata) Generally the largest and darkest race of Common Redpoll, with a deeper and wider base to the bill than Mealy, being notably more convex on the culmen and gonys. Plumage colouration and extent of dark streaking on the upper and under-parts very similar to Lesser Redpoll, but mantle and scapulars a paler buff/brown, so less tawny than seen on Lesser. Greenland Redpoll (rostrata) These birds are characterized by their dark chocolate brown appearance.
