2010-04-19 · redpoll / April 19, 2010 The Redpolls are a group of small passerine birds in the finch family Fringillidae which have characteristic red markings on their heads. They were formerly placed into the genus Acanthis together with the linnets and the twite, but their closest relatives are actually the crossbills, that are placed in the genus Loxia . I was lucky to see some birds in the hand with at least one Coues' Arctic Redpoll (exilipes) and a candidate Greenland Mealy Redpoll (rostrata) First year Coues' Arctic Redpoll, note buffy wash on the face and broad white rump.

NORTHWESTERN REDPOLL Carduelis rostrata – another high Arctic species occurring from eastern Baffin Island to the west and east coasts of Greenland. It includes the Icelandic form islandica. The relationship with the North American Mealy Redpoll is uncertain, this redpoll type occurring from west

They have a huge bill and are heavily streaked.

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. These small finches of the arctic tundra and boreal forest migrate erratically, and they occasionally show up in large numbers as far south as the central U.S. During such irruption years 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. The Arctic redpoll is the one that causes the least confusion because of it much paler than its two cousins. It is found in North American and Eurasia and is known as the hoary redpoll in North America while there is a subspecies known as the Greenland Arctic Redpoll that lives, as the name suggests, in Greenland.
