Pyrrhula is a small genus ofpasserine birds, commonly calledbullfinches, belonging to the finch family (Fringillidae). The genus has aPalearctic distribution; almost all species occur in Asia, with two species exclusively in theHimalayas and one species,P. pyrrhula, also occurring in Europe. TheAzores bullfinch (P. murina) is acritically endangered species (about 120 pairs remaining), occurring only in the east of the island ofSão Miguel in theAzoresarchipelago.
Theevolution of the bullfinch species started soon after the pine grosbeak's ancestors diverged from them (at the end of the MiddleMiocene, about 12mya), and it is quite possible that the latter species evolved in North America; what is fairly certain is that the bullfinch radiation started in the general area of the Himalayas. Themountain finches also seem to be part of thisclade.[2]
Bullfinches have glossy black wings and tail feathers. They show a white rump. The legs and feet are fleshy brown. Their short, swollen bill is adapted to eat buds, and is black except for thebrown bullfinch, which has a grey or greenish-grey bill. The males can be distinguished by their orange or red breast. Some species have a black cap.
