Similar Species

Hoary Redpoll is larger and paler with shorter, thicker bill and usually more extensive thigh feathering. Undertail coverts usually unstreaked. Lesser Redpoll smaller, darker and more heavily streaked. Some individuals not safely identified.

Distribution

Breeds in the northern parts of the New and Old Worlds. Winter range extends farther south, but is not very predictable. An irruptive species, this bird can be abundant in places some winters and completely absent in other winters. Birds ringed in Norway have been recovered in China just north of the border of North Korea, about 4000 km away from Troms County.

Taxonomy

Subspecies rostrata

Formerly placed in genus Carduelis. Lesser Redpoll formerly included in this species. A. f. islandica considered a synonym of A. f. rostrata by Clement (2018)[3], Gill & Donsker (2018)[7], and Christides et al (2014)[6]. However its validity confirmed by Amouret et al. (2015)[2] and accepted by Clements et al. (2018)[1]. A genetic study by Mason & Taylor (2015)[5] found that phenotypic variation in all Redpolls is a result of RNA expressing plumage differences without actual differences in DNA. They advocate lumping all the Redpolls into a single species[8], but their recommendation has not yet been adopted by major taxonomic authorities.

Subspecies

There are three subspecies:[1]

  • A. f. flammea - Small and dark.
  • Northern Eurasia and northern North America
  • A. f. rostrata - Large and dark
  • Northern Labrador, Baffin Island and southern Greenland; winters to north-eastern North America and British Isles
  • A. f. islandica - Similar to A. f. rostrata but smaller and with paler rump.
  • Iceland

Habitat

Coniferous and birch woodlands.

Behaviour

Diet

The diet includes small seeds.

Breeding

It builds an open cup nest from twigs, rootlets and grasses, lined with thick layer of feathers or hair. 4-6 greenish white to pale blue, spotted with purple at large end, eggs are laid.

Vocalisation

Song usually single or repeated calls in short combinations: especially chatter and rattle calls che, che, che, tschrrrr, repeated.
