The robin’s faint song may have been one of contentment with his lot, or one of evening praise for as many mercies as he had received, but it sounded far more, in that light and that biting air, like the boy who whistles at night on the long and lonesome road to keep his courage up. Then the song died away in his throat, for across the angry crimson of the west flitted silhouetted black wings, and a pair of crows lighted among the thick boughs of the higher pines to roost for the night.
The robin muttered “tut, tut!” somewhat hysterically and slipped away to safer shelter deep among the low boughs and denser shadow of a tree on the edge of the open pasture. No doubt he recognized hereditary enemies of his race, and though he was tough enough to dare a northern winter, was unwilling to take chances with the strong black bills of these reckless freebooters of the wilderness. And he was right. Crows rarely eat grown robins, for they cannot catch them, but the tender, half-fledged nestlings are the mainstay of many a crow saturnalia.
Only too well do I remember an orgy of this sort. It was late May and the scent of the apple blossoms filled all the orchard with delight, just as the robins, morning and evening, filled it with song. They sang for every cloud that crossed the sky and piped up now and then in the full sunshine. How they found time for it all it is hard to tell, for every nest was full of young birds that eat almost their weight in hearty food each day.
One day the tunes changed. Coming into the farthest corner from a woodland trip I heard from some ancient, neglected trees, such as the robins always love and in which were grouped three or four nests, wild shrieks of anger and dismay from a whole chorus of robins. Coming nearer I could hear crow voices in guttural undertones, croaking ghoulishly.

The crow has a language, not exactly of words but of inflections and intonations, which express the primal emotions pretty clearly. I always think I know what he means, though undoubtedly his crow hearers understand the finer shades of inflection better than I do.
There is the shout of warning which says plainly, “Look out, there is trouble right ahead of you!” A similar shout, but with different inflection, says, “Come on. Come on. I’ll show you something worth seeing.” There is the yell of derision and defiance with which a flock drives an owl through the forest; there is the gentle cooing croak with which mated birds do their love-making. There is the cry of terror and the suppliant call for food from the full-grown young. There is also a peculiarly devilish croak of satisfaction which they make only when feasting on the tender nestlings of pasture birds.
