The thrasher may be just as conditioned in his joy and utterances as any other bird. His variations on the general bird theme may come out abstractly, without any attempt at parody, a limited kind of talent, and yet when I listen to it, it seems to me that the bounds of song are being just a bit extended. As compared with other birds, the blackpoll warbler for example, with only a thin, high note, reminiscent of insect sounds in the summer, the thrasher has range and repertoire. He is vocal and conversational, even to the extent of tempting at least one human animal into reading words and intentions into his performance; and this, from a bird’s point of view, might mean that I was extending my limits too. _Facets of Expression_ I make a foolish game out of attaching words to a bird’s song. Perhaps it is a way of trying to bring the two of us together in familiarity, but to give nature its true respect, every song, color, and action is its own master. Understanding, the best human means of communicating with other lives, might be most effectively attained by keeping a certain distance. That is the way I feel when I see the alert, tough little chickadees coming up to the house and picking up tufts of hair, rope, or wool, to use as nesting material. They set to work carding it so busily and self-sufficiently that I am restrained from an impulse to join in and look things over. I walk off to my own business. A pair of tree swallows is trying out a birdhouse, and when I stay too long in the vicinity, they are given an extra reason for a negative decision as to its merits and fly into the distance. This is a time not to meddle, tease, interfere, or try to imitate what cannot be imitated. From that point of view the life of May, free of human embrace, seems full of wonderful languages, still to be learned, and they are not confined to the uses of sound. Isn’t a flower or wing or new leaf articulate? I watch a mourning cloak butterfly that flits and floats overhead and then lands on a bare patch of ground in the sunlight. The broad wings fold and show their dark, woody, shadow side, with little white circles on them, their pattern and texture a blend of weather-beaten, drab forest floors, suggestive of niches and corners of leaf-decaying darkness. Then the wings spread out again. They are a light mahogany-red with shades of brown, bordered by black lines, and on their bottom edge they are rimmed with little round dashes of purplish blue, like small windows into the sky, and the body is green. The butterfly’s antennae have white tips. It has fine hairs on its back. Then, with a papery, fluttering sound, it is up with startling quickness from the ground; just out of reach, in the frequent manner of butterflies, as many a boy with a net has learned from hard experience.
