The Cuckoo is one of the most solitary birds of our forests, and is strangely tame and quiet, appearing equally untouched by joy or grief, fear or anger. Is he an exile from some other sphere, and are his loneliness and indifference the result of a hopeless, yet resigned soul? Or has he passed through some terrible calamity or bereavement, that has overpowered his sensibilities, rendering him dreamy and semi-conscious? Something remote seems ever weighing upon his mind. He deposits his eggs in the nests of other birds, having no heart for work or domestic care. His note or call is as of one lost or wandering, and the farmer says is prophetic of rain. Amid the general joy and the sweet assurance of things, I love to listen to this strange clairvoyant call. Heard a quarter of a mile away, coming up from the dark bosom of the forest or out from the sombre recesses of the mountain, like the voice of a muezzin calling to prayer in the Oriental twilight, it has a peculiar fascination. He wanders from place to place, "An invisible thing, A voice, a mystery." You will probably hear him a score of times to seeing him once. I rarely discover him in the woods, except when on a protracted stay; but when in June he makes his gastronomic tour of the garden and orchard, regaling himself upon canker-worms, he is quite noticeable. Since food of some kind is a necessity, he seems resolved to burden himself as little as possible with the care of obtaining it, and so devours these creeping horrors with the utmost matter-of-course air. At this time he is one of the tamest birds in the orchard, and will allow you to approach within a few yards of him. I have even come within a few feet of one without seeming to excite his fear or suspicion. He is quite unsophisticated, or else royally indifferent. Without any exception, his plumage is the richest brown I am acquainted with in Nature, and is unsurpassed in the qualities both of firmness and fineness. Notwithstanding the disparity in size and color, he has certain peculiarities that remind one of the Passenger-pigeon. His eye, with its red circle, the shape of his head, and his motions on alighting and taking flight, quickly suggest the resemblance; though in grace and speed, when on the wing, he is far inferior. His tail seems disproportionately long, like that of the Red Thrush, and his flight among the trees is very still, contrasting strongly with the honest clatter of the Robin or Pigeon.
