time, nearly two minutes, as we calculated. Their wings were outspread, and their forms were indistinguishable. They tugged at each other most doggedly; one or the other brown breast was generally turned up, partly overlaid by a blue coat. They were determined to make a finish of it this time, but which got the better of the fight I could not tell. But it was the last battle; they finally separated, neither, apparently, any the worse for the encounter. The females fought two more rounds, the males looking on and warbling approvingly when they separated, and the two pairs drifted away in different directions. The next day they were about the box and tree again, and seemed to have definitely settled matters. Who won and who lost I do not know, but two pairs of bluebirds have since been very busy and very happy about the two nesting-places. One of the males I recognize as a bird that appeared early in March; I recognize him from one peculiar note in the midst of his warble, a note that suggests a whistle. The matchmaking of the high-holes, which often comes under my observation, is in marked contrast to that of the robins and bluebirds. There does not appear to be any anger or any blows. The male or two males will alight on a limb in front of the female, and go through with a series of bowings and scrapings that are truly comical. He spreads his tail, he puffs out his breast, he throws back his head, and then bends his body to the right and to the left, uttering all the while a curious musical hiccough. The female confronts him unmoved, but whether her attitude is critical or defensive I cannot tell. Presently she flies away, followed by her suitor or suitors, and the little comedy is enacted on another stump or tree. Among all the woodpeckers the drum plays an important part in the matchmaking. The male takes up his stand on a dry, resonant limb, or on the ridgeboard of a building, and beats the loudest call he is capable of. The downy woodpecker usually has a particular branch to which he resorts for advertising his matrimonial wants. A favorite drum of the high-holes about me is a hollow wooden tube, a section of a pump, which stands as a bird-box upon my summer-house. It is a good instrument; its tone is sharp and clear. A high-hole alights upon it, and sends forth a rattle that can be heard a long way off. Then he lifts up his head and utters that long April call, _Wick, wick, wick, wick_. Then he drums again. If the female does not find him, it is not because he does not make noise enough. But his sounds are all welcome to the ear. They are simple and primitive and voice well a certain sentiment of the April days. As I write these lines I hear through the half-open door his call come up from a distant field. Then I hear the steady hammering of one that has been for three days trying to penetrate the weather boarding of the big icehouse by the river, and reach the sawdust filling for a nesting-place.
