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.

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.
