In structure and some of its habits much resembling a bullfinch, but much exceeding that bird in size, it has the plumage of a crossbill and appears to undergo the same changes as do the members of the restricted genus Loxia - the young being of a dull greenish-grey streaked with brownish-black, the adult liens tinged with golden-green, and the cocks glowing with crimson-red on nearly all the body-feathers, this last colour being replaced after moulting in confinement by bright yellow.
This is the case of the bullfinch of the more western of these islands (Pyrrhula murina), the male of which, instead of the ruddy breast of its well-known congener (P. vulgaris), has that part of a sober mouse-colour.

Fringilla), a name applied (but almost always in composition - as bullfinch, chaffinch, goldfinch, hawfinch, &c.) to a great many small birds of the order Passeres, and now pretty generally accepted as that of a group or family - the Fringillidae of most ornithologists.
By gardeners the bullfinch has long been regarded as a deadly enemy, from its undoubted destruction of the buds of fruit-trees in spring-time, though whether the destruction is really so much of a detriment is by no means so undoubted.
A bullfinch (P. cassini) has been discovered in Alaska, being the first recognition of this genus in the New World.
With the exception of the single species of bullfinch already noticed as occurring in Alaska, all the above forms o£ finches are peculiar to the Palaearctic Region.
