March 4th. R extends his search. 10:50 A.M. Rhody has not been heard near this morning, but at 9:45, from Dr. Reynolds's house I could hear him (presumably) calling several hundred yards away across Dimond Canyon; so he is searching far off. Thrasher on nest A half hour earlier one of the thrashers was sitting quietly in the nest. Terry whines at Archie. On returning here Archie and Terry, as now the regular thing, whined plaintively on my approach. Archie flew up to the sand box in which T was sitting, carrying a small pebble. He leaned over T and T raised his head and directed his mewing to Archie--the first time this has been noted. A dropped the pebble by T, nothing happened. This action may have been merely a coincidence, but it is possible that it may indicate arousing of the reproductive instinct. A & T's calling to me increasing in persistency. For the last few days A and T have been very persistent in whining when I appear. Sometimes they appear satisfied on being given food or a drink, at others when I merely enter the cage; but often it makes no difference if they have just had a good meal. I worked most of the day on another extension of the cage where they could see me all the time. Yet they continued to call in this way repeatedly. A's hroo heard on shoulder. This morning Archie hrooed on my shoulder while sunning there, with his feathers tickling my ear. It is every musical sound, not always of the same pitch. One phase of it is deep and guttural with vibrato, almost gruff. Rhody back. At about 3:30 Rhody had had enough for the day of his search in distant regions and returned home, unruffled and calm, unforgetful of the attractions of Hamburger steak. At 4:25 he climbed up to his regular roost--an early retirement for this season--induced perhaps by the fatigue of climbing about the hills in search of a mate. (Sunset 6:06, bright, fair and summerlike, so there was nothing about the weather to influence his action). March 5th Rhody was not heard calling this morning at all. He came to the cage for meat at 11:45, and was much interested in the youngsters, watching them closely for about 20 minutes. Terry was rather indifferent to him, but Archie talked to him, raised his crest and approached near to him several times. Rhody seemed to (or rather did) pay most attention to Archie, and at one time tried to get at him by following up the wire outside. A's comments consisted of repeating hahk, hahk. R was silent. I gave R a live mouse after he had eaten meat. He sat by the cage with it in his bill, quietly, for about 10 minutes. When he went off with it, I followed. He would trot slowly about 6 feet at a time and then stop, looking carefully in all directions. It was not until he reached a point in the street below about 20 yards directly in front of the Scamell house that he began to wag his tail sidewise. The Scamell dining room window is always an attraction to him and he ran over to it with the mouse and wagged his tail vigorously. His tail is so heavy that it also "wags" him. Incidentally, also, the pendulum-like swinging of a mouse
