There has been an unusual number of shrikes the past fall and winter; like the hawks, they follow in the wake of the little birds and prey upon them. Some seasons pass and I never see a shrike. This year I have seen at least a dozen while passing along the road. One day I saw one carrying its prey in its feet,--a performance which I supposed it incapable of, as it is not equipped for this business like a rapacious bird, but has feet like a robin. One wintry evening, near sunset, I saw one alight on the top of a tree by the roadside, with some small object in its beak. I paused to observe it. Presently it flew down into a scrubby old apple-tree, and attempted to impale the object upon a thorn or twig. It was occupied in this way some moments, no twig or knob proving quite satisfactory. A little screech owl was evidently watching the proceedings from his doorway in the trunk of a decayed apple-tree ten or a dozen rods distant. Twilight was just falling, and the owl had come up from his snug retreat in the hollow trunk, and was waiting for the darkness to deepen before venturing forth. I was first advised of his presence by seeing him approaching swiftly on silent, level wing. The shrike did not see him till the owl was almost within the branches. He then dropped his game, which proved to be a part of a shrew-mouse, and darted back into the thick cover uttering a loud, discordant squawk, as one would say, "Scat! scat! scat!" The owl alighted, and was, perhaps, looking about him for the shrike's impaled game, when I drew near. On seeing me, he reversed his movement precipitately, flew straight back to the old tree, and alighted in the entrance to the cavity. As I approached, he did not so much seem to move as to diminish in size, like an object dwindling in the distance; he depressed his plumage, and, with his eye fixed upon me, began slowly to back and sidle into his retreat till he faded from my sight. The shrike wiped his beak upon the branches, cast an eye down at me and at his lost mouse, and then flew away. He was a remarkably fine specimen,--his breast and under parts as white as snow, and his coat of black and ashen gray appearing very bright and fresh. A few nights afterward, as I passed that way, I saw the little owl again sitting in his doorway, waiting for the twilight to deepen, and undisturbed by the passers-by; but when I paused to observe him, he saw that he was discovered, and he slunk back into his den as on the former occasion.
