proaching it: He bows nearly to the ground, hroos deeply in his throat and waves his tail back and forth rapidly, the effort caus- ing his body to oscillate. Following this, or even omitting it entirely, he steps close to the mirror, standing erect and places the tip of his bill against the glass moving it about and saying coot,coot,coot..... at the rate of 4 or 5 times per second. This is the second type. In wandering about with the mouse, whenever he has occasion to pass close to me, he nearly always begins this coot, coot a few feet before he reaches the point nearest to me, keeps it up while passing and stops it a few feet beyond. At 11:45 I was on Sandringham Road north of this house and perhaps a hundred feet lower, and west of the Nichols house which is at about the same elevation, and about 100 yards from both houses. The open, sloping area intervening is covered with a growth of baccharis with patches of wild strawberry, blackberry and honey- suckle low to the ground. Rhody was seen on top of the Nichols house. I went up the slope and when I looked up again, it was to see him now on the ground 15 or 20 feet away. He must have sail- ed down about 75 feet and as many yards to join me. He did not greet me at all, but immediately began to move about slowly scanning the surface of the ground with an air of alert interest, making short dashes of 2 or 3 feet to prod suddenly at the earth, following with a side-sweep of the bill. He was forag- ing. So I spent the next half hour following him about watching. By far the most of his efforts were unproductive; after each such he snapped his bill two or three times to remove the earth. Like so many of his other performances, he seemed to dramatize this one: with exaggerated poses and gestures. His prey consisted, as far as I could determine, principally of Jerusalem crickets. His sense of hearing seemed to be the most effective guide. He did not once apply to me for food. We soon accumulated a following of white-crowned-and song- sparrow and brown and spotted towhees. These birds made no com- plaint. The White-crowns permitted me to walk about within 6 feet of them without flying away. All birds were intent upon Rhody, practically disregarding me. About 4 P.M. I sat near the cage with two visitors (Dr. and Mrs. Fraser) when Rhody appeared, saw the company and beat a retrea I went to the tool-house to get him a mouse and induce him to re- turn and be introduced; but when I got back to the cage, he "knew" I should, by precedent, be at the tool-house, so he went there and looked in through the window. However, he was persuaded to come back and take the mouse in front of the visitors and treated it with full honors, following up with presentation at the mirror. At 5:30 I went to look him up at his roost. (Cloudy, warm). I wanted to see whether he would occupy the house, now that he has started a nest in it. I had to go up and stand below it before I could see his bill sticking out above the nest. He was as far back in the house as he could get, looking snug and secure, tail up against the rest provided for that purpose--all in accordance with the plan of the builder. This is the first instance of his being seen to put up for the night in a nesting place, or, perhaps more precisely build a nest in a roosting place. March 11th. At 8 A.M. Rhody had left his roosting place. He was found (or rather he found me) about 8:15 near the tool house where I had been
