Falco columbarius. Lake Umbagog, Maine. 1895. As we neared the entrance to Leonard's Pond a Pigeon Hawk Sept. 10., alighted on a stub which stood on the river bank. We approach- ed to within easy range when I saw that the bird was a fine adult male but before I could raise the gun it flew and I missed it as it was making off. Less than one hundred yards further on I was surprised to see at least a dozen Yellow- rumped Warblers in a dying and nearly leafless maple which overhung the water. They were hopping and flitting about but did not appear to be especially active or excited and were ma- king no noise. While I was looking at them my eye was attract- ed to an upright motionless form in the centre of the tree and this I made out through my glass to be another Pigeon Hawk, a young bird, apparently a male. It was evidently the object which had excited the interest of the Warblersbut they did not appear to be in the least afraid of it, for they repeatedly approached within four or five feet of it, always however keep- ing above it. The Hawk did not seem to notice them, but kept its gaze fixed on the ground beneath as nearly as I could judge from the position of its head. I was on the point of shooting at it when, like the other, it escaped by taking flight, but my shot cut several feathers from it and it went off as if badly wounded dropping into a thicket of alders where we could neither find it or flush it. Early this morning I had seen still a third Pigeon Hawk 99
