This is a rare Finch, and its massive beak and rich blue plumage give to

it a highly interesting appearance; but about its habits I have little

to tell, for it is essentially a bird of the wild forest, seldom coming

near the abodes of man, and being, moreover, shy in disposition, it is

difficult to observe it even in its haunts. It is migratory, and is

usually seen singly or in pairs, or in small companies of four or five

individuals. The male sings, but his performance is merely a confused

medley of chattering notes, uttered in so low a tone that they can

scarcely be heard at a distance of twelve yards.
