Wikipedia Abstract

The two-barred crossbill (Loxia leucoptera), known as the white-winged crossbill in North America, is a small passerine bird in the finch family Fringillidae. It has two subspecies, white-winged crossbill Loxia leucoptera leucoptera in North America, and two-barred crossbill Loxia leucoptera bifasciata in NE Europe and N Asia. The scientific name is from Ancient Greek. Loxia is from loxos, "crosswise", and leucoptera means "white-winged" from leukos, "white" and pteron, "wing".
