The chaffinch makes the most of his song. He appears, indeed, very much in earnest in whatever he does, his character in this respect offering a strong contrast to that of the goldfinch, siskin, and various other melodists. They sing at all times, anywhere and anyhow. With the chaffinch, singing is a business just as important as any other--feeding, fighting, pairing, and building. He flies to a tree, and deliberately takes his stand, often on the most commanding twig, and there delivers his few notes with the utmost energy, and so rapidly that they almost run into each other, ending with a fine flourish. At regular intervals of a few seconds the performance is repeated, the bird standing erect and motionless all the time; until, having given the fullest and most complete expression to his feelings, he flies away, to engage elsewhere in some task of another kind. It is a loud song and a joyous sound--‘gay as a chaffinch’ is a proverbial saying of the French; but there is also a note of defiance in the song, as in the crow of a cock. Chaffinches sing, as cocks crow, against each other, and the music often ends in a combat. It is not, as some imagine, that there is a spirit of emulation in birds with regard to their singing--that they are rival musicians, like the shepherds in the old pastorals, that contended in song for mastery: it is simply that the cock chaffinch, like the robin and some other species, is a bird of a jealous and pugnacious disposition, and can brook no other male chaffinch near him. Another’s singing tells him that another male is present, and his jealousy is at once excited. If the sound is at a distance, he will content himself by answering song with song; if near, he will quickly seek out the singer, and drive him from his chosen ground. It is this jealous temper of the chaffinch that gives it value to the bird-fanciers of a base kind.
