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. 2008-03-07 German: Birkenzeisig-rostrata English: Common Redpoll (rostrata), Greenland Redpoll French: Sizerin flammé du Groënland, Sizerin flammé du Groënland (rostrata) Scientific: Acanthis flammea rostrata, Acanthis flammea rostrata (rostrata), Aegiothus rostratus, Carduelis flammea rostrata, Carduelis flammea rostrata (rostrata) Dutch: Grote Barmsijs This Greater Redpoll was found in a large flock of Common Redpolls (Acanthis flammea flammea) in Centre County Pennsylvania on March 29, 2013.

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.

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.

Then you get big white ones that are not quite white enough and that are thought to come from Iceland ( icelandica ) – I have no idea what you can call these but let’s stick with Common Redpoll .

Common Redpoll - Acanthis flammea rostrata L ' Common Redpoll the variety, the scientific name is derived from flammea latione and means "flame-colored" due to the red livery. The cap is bright red in both sexes, thus not constituting a reason for sexual dimorphism. As energetic as their electric zapping call notes would suggest, Common Redpolls are active foragers that travel in busy flocks. Look for them feeding on catkins in birch trees or visiting feeders in winter.

In winter, the gorges are visited by birds such as siskin, redpoll and pochard. The Greater Redpoll ( A. l.

A Greater Redpoll (Acanthis flammea rostrata) in PA. Drew Weber March 29, 2013 Birding, Identification Leave a Comment. Today while looking through a large flock of 100 to 200 redpolls in Centre County PA, my eye was drawn to a redpoll that was larger and darker streaked than all the nearby redpolls.

With the exact extent of interbreeding between hoary redpolls (Acanthis hornemanni, aka Arctic redpoll) and common redpolls remaining unknown up-to-date, it can be quite difficult to separate these birds at a mere glance.

All the common Redpolls I have seen this year have been feeding on birches or weed seeds. Photos were taken at the NH coast Acanthis flammea rostrata nästa/next Antal fynd/individer (number of records/individuals): 1/1 1: 2006 30.12, 1 1 cy. 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.
