Bird Papercraft - Pyrrhula Free DownloadThis animal papercraft is a Pyrrhula, created by gansuke. Pyrrhula is a small genus of passerine birds, commonly called Bullfinches, belonging to the finch family.

The genus has a palearctic distribution. All species occur in Asia with two species exclusively in the Himalayas and one species, P. pyrrhula, also occurring in Europe. The Azores Bullfinch is a critically endangered species, occurring only in the east of the island of São Miguel in the Azores archipelago.

Analysis of the mtDNA cytochrome b sequence indicates that the holarctic Pine Grosbeak is the closest living relative of this genus. Arguably, it could be included in Pyrrhula, but more probably is a distinct offshoot of a common ancestor, with the Pine Grosbeak as the sister group to the ancestor of the bullfinches. The evolution of the bullfinch species started soon after the Pine Grosbeak's ancestors diverged from them, 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. The mountain finches also seem to be part of this clade.

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 in P. nipalensis, which has a yellowish bill. The males can be distinguished by their orange or red breast. Some species have a black cap.

Bullfinch species are sedentary to migratory; probably most populations are partially migratory. Populations winter chiefly within the breeding range, those breeding at high levels tending to make altitudinal movements. Most migrants move short or medium distances, but some move longer distances; in northern and central Europe, there is no evidence that northern populations move farther than southern ones. North European birds move within a wider compass than central European birds. Bullfinches are also eruptive migrants; numbers migrating show marked annual fluctuations; no link with particular food source has been established. Autumn migration begins late, and is fairly brief, mostly October–November; spring migration February - April.
