Arctic
Redpoll, Carduelis hornemanni

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
. The latter genus could be merged with Carduelis
in a single
genus, for which the name Loxia would then have priority.
But this would imply to change the name of a large number of
species, and as their adaptations and biogeography are evolutionarily
quite peculiar, it would be better to reinstate Acanthis
instead, including only the redpolls. |
There are several different very closely related forms of redpolls
which could be considered as anything from one to five species.
Recent studies tend to support
three species,
but this is certainly not definite.
The three species are:
The Arctic Redpoll, Carduelis hornemanni
(subspecies C. h. hornemanni and C. h. exilipes)
The Common Redpoll, Carduelis flammea
(subspecies C. f. islandica and C. f. rostrata)
The Lesser Redpoll, Carduelis cabaret

They are primarily seed-eaters, and often feed acrobatically like
a tit; their diet may include some insects in summer.
They have a dry reeling song and a metallic call.
They lay 4-7 eggs in a nest in a tree or, in the case of Arctic
Redpoll, a large bush.
They can form large flocks outside the breeding season, sometimes
mixed with other finches.
The redpoll, which is not - as the norwegian name indicates: Grey
Redpoll - is not as grey, at least not the male, and neither the
eggs.
They often form flocks during winter, and you may see them hanging
donw from the tip of thin birch-branches.

Lesser Redpoll, Carduelis cabaret
Brownish streaky (often very bright) on top of tail, strong streaked
brown back, streaked light brown breast and flanks, black mask around
the bill, red on top of a brown head, and a white bar on the wings.
The Lesser Redpoll breeds in the British Isles, around the Alps
and the North Sea from northern France to south-east Norway.
It has spread in the last 50 or so years into southern Scandinavia
and this has led to its recognition as a species in its own right.
Common Redpoll, Carduelis
flammea
Greyish brown strong streaked breast, red and light streaked breast,
streaked flanks, light bellow, red on top of head, black mask around
nose, white bar on wings. All this means it is very like the other
Redpolls.
Previously, The Lesser Redpoll was
treated as a subspecies of Common Redpoll
Carduelis flammea but this expansion brought
the two subspecies cabaret and flammea into direct
contact. When this happened, it was observed that the two subspecies
did not
hybridise and the subspecies were split.
The reference for this is "The taxonomic status of Lesser Redpoll"
2001 by Alan Knox et al. in British Birds, 94: 260-267.

All redpolls are northern breeding woodland species, associated
with birch trees. They are small dumpy birds, brown or grey-brown
above and with a red forehead patch. The adult male's breast is
washed in red, but in females and young birds the buff breast and
white belly are streaked with brown. The bill is small and yellow.
Some birds, particularly young ones, are difficult to assign to
species

Compared with Common Redpoll, Lesser Redpoll is significantly smaller
and has richer plumage tones. Vocalizations are also slightly different.
How it is compared to the other Carduelis-birds I don't know.
Why don't I know? Well, just look below:
