1364 without being called, loitered about my feet looking up at me, then led the way to the tool-house, stopping every few feet for me to catch up, then running about me like a dog as if anxious not to be overlooked. I really had to be careful to avoid stepping on him. I have not seen him so animated and attentive to my movements on previous similar occasions. As we approached the mousery, R still thought I should get them in the yard, so darted there, while I went to the tool-house; but he soon discovered his mistake. I selected a very large mouse for him--one that taxed even his swallowing powers, for he had diffi- culty in getting its hind-quarters past the corners of his mouth. This time there was no thought of using it as a lure for another bird--he wanted it himself--and that quickly. --At 2:35 I found him in the orchard. He cried on seeing me. (At 1:30 he did not). He wanted another, only an hour and a quarter after eating the big one, and disposed of it with despatch. As he was fed but once yesterday, his hunger today may be an indication that he did not forage yesterday at all--at least suc- cessfully. At 4:35 he jumped across to his roost, having taken only a min- ute or two to pass through the ladder tree as he was frightened by 5 persons who were examining the property. They all saw him make his last leap. A lady in the party was well acquainted with road- runners and told me of a fight she had witnessed in Arizona between a road-runner and a rattlesnake about 2 feet long. It lasted, she said 2(?) hours, but they had to leave without seeing the finish. As a curious coincidence, I had with me a copy of the pictorial monthly "Look" for March, not knowing its contents. When I reach- ed the house and opened it, there was a photograph of a road-run- ner and a snake (said to be a rattlesnake) fighting! February 3rd. (Temperatures this day were of the order of 45 min. 55 max. Increasing cloudiness). Mr. S saw Rhody about 9 A.M. at his post, called to him and he responded with his spring song. I looked for him several times during the forenoon without success and decided he was off on tour somewhere. (I have suspect- ed a tendency on his part to cruise farther immediately after a day when he was unusually well fed). At 2:45, while I was in the cage, I saw Rhody coming. He snatched up a billful of pine needles, carried them past R5 who was in the outer cage with me, and dropped them about 5 feet beyond R5 and near the wire, without once appearing to look at R5. He now sat quietly close to the wire, R5 pacing up and down nearby, much interested in R, who apparently ignored R5. Rhody went to the mirror to take one glance at himself, then returned to his former post near me, where I gave him a mouse. He ate it without running away. I now had both birds in view close by, R within 3 feet sitting quietly and R5, 2 to 8 feet moving about composedly. This condition lasted about 15 minutes, then R left. There was no display by either bird, no vocal sounds uttered and nothing interpretable (by me, at least) as throwing any light upon R5's sex. Rhody "still" is the heavier and larger bird. This is true especially as regards head and beak. R5, though of course it is too much to expect one to carry indefinitely an accurate image in one's mind of Archie and Terry, seems much like them, and it may be that he is a yearling, not yet fully mature. He has not sung
