Purple finch There are two subspecies of the purple finch, "H. p. purpureus" and "H. p. californicus". "H. p. californicus" was identified by Spencer F. Baird in 1858. It differs from the nominate subspecies in that it has a longer tail and shorter wings. The plumage of both males and females is darker, and the coloration of the females is more greenish. The bill of "C. p. californicus" is also longer than that of the nominate subspecies. Adults have a short forked brown tail and brown wings and are about in length and weigh . Adult males are raspberry red on the
Small ground finch Latin for "sooty". It is known to hybridize (rarely) with the medium ground finch. This is the smallest of the ground finches, measuring in length . Its beak is short and pointed, with a slightly curved culmen. On average, its beak is smaller than that of the medium ground finch, though there is a significant overlap in size between the two, particularly on islands where only one of the two species exists. On islands where the two species compete directly, the differences between their beaks are greater. The male is black with white-tipped undertail coverts, while the female and young
