BIRD-SONGS.
Canst thou imagine where those spirits live
Which make such delicate music in the woods?
Shelley.
Why do birds sing? Has their music a meaning, or is it all a matter of blind impulse? Some bright morning in March, as you go out-of-doors, you are greeted by the notes of the first robin. Perched in a leafless tree, there he sits, facing the sun like a genuine fire-worshiper, and singing as though he would pour out his very soul. What is he thinking about? What spirit possesses him?
It is easy to ask questions until the simplest matter comes to seem, what at bottom it really is, a thing altogether mysterious; but if our robin could understand us, he would, likely enough, reply:—
"Why do you talk in this way, as if it were something requiring explanation that a bird should sing? You seem to have forgotten that everybody sings, or almost everybody. Think of the insects,—the bees and the crickets and the locusts, to say nothing of your intimate friends, the mosquitoes! Think, too, of the frogs and the hylas! If these cold-blooded, low-lived creatures, after sleeping all winter in the mud,[3] are free to make so much use of their voices, surely a bird of the air may sing his unobtrusive song without being cross-examined concerning the purpose of it. Why do the mice sing, and the monkeys, and the woodchucks? Indeed, sir,—if one may be so bold,—why do you sing, yourself?"
This matter-of-fact Darwinism need not frighten us. It will do us no harm to remember, now and then, "the hole of the pit whence we were digged;" and besides, as far as any relationship between us and the birds is concerned, it is doubtful whether we are the party to complain.
