The rambler not only sees many of these pretty bird ways, but he sometimes has a hearty laugh at the birds' expense. During one of my outings a blustering whirlwind started on the summit of a small hill scantily covered with scrub oak. It seized the dead leaves and twirled them about as if in a spasm of anger; then it went scurrying noisily down the steep incline, flinging itself against a couple of large brush heaps in the hollow where a number of fox and Harris sparrows were concealed. They had imagined themselves safe in their brushy covert. Suddenly the whirlwind struck their hiding place with a clang and clatter, sending the birds in a wild panic in every direction. They did not seem to know what had struck them, and, as the wanton breezes tossed them this way and that, they expressed their astonishment in loud and frightened chirping. All over and no harm done, the bird lover burst into a peal of laughter at the discomfiture of his feathered neighbors, who looked at him as if they did not know what to make of his untimely hilarity. Then, too, one cannot be an observing rambler without stumbling upon some exceedingly odd avian pranks, as the following description will indicate: One day I was sitting on the steep bank of a wooded ravine watching several rare little birds, hoping to discover some of their nests. Presently the susurrus of the hummingbird was heard, and a moment later two ruby-throats, a male and a female, flashed into view on the slope below me. The tiny madam settled on a twig near the ground, while her ruby-throated spouse performed one of the queerest antics I have ever witnessed in featherland. He began to swing back and forth in an arc of almost half a circle, the diameter of which was at least twelve feet, just grazing his mate whenever he reached the lowest point of his concentric movements. Back and forth he swung at least a dozen times, looking like a tiny pendulum moving in an immense arc, and, oddly enough, the segment seemed to be perfectly formed every time. Had the bird wheeled entirely around, he would, I feel sure, have described a circle and not an ellipse. The movement was exceedingly swift, and might well have been called the embodiment of grace. Suddenly, as the diminutive acrobat reached the highest point of his arc, he dashed off to the right in a straight line, followed by his mate, and in a moment both had disappeared. Whether other observers have been witnesses of this curious gambol, I am unable to say.
