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 bullfinch, common bullfinch or Eurasian bullfinch (Pyrrhula pyrrhula) is a small passerine bird in the finch family Fringillidae. In Anglophone Europe it is known simply as bullfinch, as it is the original bird to bear the name bullfinch. Cassin's Bullfinch (Pyrrhula pyrrhula cassinii S.F. Baird, 1869) is found in Russian Far East and north-eastern China.
