Similar Species
Great Rosefinch is almost as large, and overlaps marginally in the northern Altai Mountains of central Asia; it differs most obvously in lacking the white wingbars. Also compare with the much smaller White-winged Crossbill.
Distribution
Northern boreal Europe, Russia, and North America.
- Europe: breeds in northern Scandinavia and northern Russia; winter visitor a short way further south, very rarely as far southwest as Britain and the Netherlands.
- Asia: breeds right across the northern taiga belt, again wintering to a little further south.
- North America: breeds in Alaska, much of Canada and along Rocky Mountains and Sierra Nevada in western USA; winter visitor south to north-western and north-eastern USA.
Taxonomy
Recent genetic data indicate that the birds in Eurasia and North America are diverged enough to be different species[3]; there are also small plumage differences, particularly in females.
Subspecies
Nine to eleven subspecies are recognised in the two groups[1][2]:
- Eurasia (Pinicola enucleator sensu stricto) — females with yellow / orange extending onto mantle, breast and flanks
- P. e. enucleator: northern Scandinavia to Russia and western Siberia (Yenisey River)
- P. e. pacata: Siberia (east of Yenisey Rier) to Altai Mountains, Mongolia and Manchuria
- P. e. kamtschatkensis: far-eastern Siberia (Anadyr River) to Kamchatka
- P. e. sakhalinensis: Sakhalin, Kuril Islands and high mountains of Hokkaido
- North America (if split, becomes Pinicola leucura) — females greyer, with yellow / orange usually restricted to head and rump, only rarely on breast
- P. e. flammula: southern Alaska to northwestern British Columbia; winters to north-western US
- P. e. carlottae: islands and coasts from Haida Gwaii to Vancouver Island
- P. e. montana: interior central British Columbia to Rocky Mountains of south-western US
- P. e. californica: Sierra Nevada mountains (eastern California)
- P. e. leucura: breeds in the boreal zone of North America, from Alaska east to southern Quebec and Newfoundland; resident, but some disperse south in winter
Habitat
Breeds in coniferous and mixed woods, pond and stream edges, and the edges of open fields and marshes. In winter, more often in mixed forests, woods and gardens with abundant berry-bearing trees, particularly rowan (Sorbus).
Behaviour
Diet
Includes the buds of many trees, including maple, birch, apple, rowan, poplar, and willow and the fruit of rowan, whitebeam, crab apple, barberry, and the seeds of birch, pine, and spruce trees. Also grass and weed seeds and various insects, and readily takes sunflower seeds on birdtables in winter.
Breeding
A monogamous species. They breed between May and July, building an open cup nest in a tree. The clutch consists of 2-5 pale blue eggs with dark spots.
Vocalisation
Song: Similar to Purple Finch's song, but it varies more in pitch and has more distinct, less-slurred notes.
