that hands, so that reflex, or whatever it is, that constrains a bird to attempt to hold its head fixed in space when its body is moved, was clearly not working and he had also "forgotten" to re-direct his attention toward the point of danger. A glance in Terry's direction showed him frozen in the corner with his tail bent in a horizontal plane at right angles to his body. The time of Archie's solidification was 1:20 P.M. I naturally wished to see how Rhody reacted to all this, but considered it the part of wisdom first to prepare myself adequate- ly to enforce my own ideas as to the measures which should be taken in preserving Nature's balance within my property lines. As a consequence some 3 or 4 minutes elapsed before I reached Rhody's supposed location with a gun, keeping a sharp lookout for the raider. Rhody was not more than 3 or 4 feet from where I thought he should be, but although the brush was not dense, it was perhaps a minute before I saw him, so perfectly does his plumage blend with the sage, baccharis, broom and mimulus forming his retreat. While he was lying quietly upon the ground, he was moving his head about cautiously and was not frozen. He did not look at me at all. A search for the hawk proved fruitless. At 1:35 both youngsters were still frozen in unchanged attitudes, but Terry seemed some- what more "limber". Neither would accept a proffered meal-worm, though Terry rolled his eyes at it without moving his head. After 20 minutes had elapsed from the appearance of the hawk, Terry would reach out and touch the worm gently with his bill and follow the movements of my hand as I withdrew it, with his eyes, and Archie would eat those offered him. Rhody, who had moved to a more comfortable location, about 5 feet from his original one, and was now lying upon a flat spray of foliage overhanging the bank of the road, would reach eagerly for all offerings, but not shift position to do so. At about 1:45 Terry accepted worms, but he was still in the same awkward posture. Both young birds gradually relaxed and settled more comfortably upon their shelves, but it was a full hour before either altered sensibly the pose of his head and body or shifted his feet, and it was 2:30 before Terry got up and stretched, followed almost immediately by Archie's standing up and looking about. Both birds now became quickly nor- mal to all appearances and moved about unconcernedly. Rhody left about this time and wandered off slowly. When I thought he was about due at his night roost, I went there. In a few minutes he was seen climbing out upon the branch of the adjoin- ing tree which he uses as a highway and at 3:16 jumped across the gap and settled in his night roost. The sun was shining brightly in a cloudless sky with sunset more than an hour and a half away. But that is Rhody. His two children were an hour to an hour and a half later in retreating to their bunks for good. December 16th. to 24th., incl. (Notes written on Dec.24). Terry's new adult gesture. About the only new happening in this period was Terry's unexpected use of a gesture hitherto observed only in the case of Rhody and then only during the mating season. Terry, in greeting me one morning (21st.) with his usual lowered head and plaintive whine, suddenly jumped down from his perch, cocked his tail up perpendicularly and clapped his wings three times in rapid succession above his back. A half hour or so later he did it again. He is growing up! Here is one event in which he has anticipated Archie. Archie's bill. The decurved tip of the upper mandible now projects percepti- ibly below the lower, but not so much as Terry's. (The tip was brok en off on Aug.18).
