Crossbill, White-winged Crossbill
Russian: Белокрылый клёст
Mongolian: Тольт солбинхушуут
French: Bec-croise bifascie
Japanese: ナキイスカ (Naki-isuka)
½ -16 cm.
Probably breeds regularly only in Russia; in some years nests in
Finland and Sweden. Prefers larch cones; often takes rowan berries in winter.
Identification: Plumages similar to
those of other crossbills, but adult ♂ often brighter, raspberry-red, and
scapulars and tail-coverts have darker centres. A bit smaller than Common
Crossbill (though some overlap), and bill not quite as heavy. Best identified
by voice and by broad white wing-bars and clear-cut broad white tips to tertials.
- Adult: Very broad white wing-bars and tertial tips make it unmistakable.
Juvenile: Underparts greyish, boldly streaked; wing-bars and tertial tips
considerably narrower than on adult. (Some Common Crossbill have pale/white
wing-bars and tertial tips, but usually one or both wing-bars are incomplete,
and tertials generally have just narrow pale fringes at tip, not broad,
clear-cut and white tips.)
- 1st year: Some are identifiable by retained juvenile
wing-coverts and tertials with little white.
