or other, had difficulty about getting in, tried a new route, then another one beginning with the roof, gave up, and took the twig to nest 2-36. While he was there I inspected the surroundings of the glass house, cut out a few interfering twigs and fixed a perch a foot or so below it where it would be handy for him to use going in and out, and awaited results. He came back (about 4 o'clock) walked around slowly, more or less aimlessly, then sauntered over to the dormitory tree, looked up at the house, decided to go up. This he did by the new route via the perch. He must have wondered how all that stuff got inside. But he adopted it at once, and although he had gone up empty "hand d" began to rearrange things to his satisfaction. After about 5 minutes he bethought himself of the magpies, entered the cage, and as it developed, was finished for the day with both nests. I joined him there in an endeavor to get some colored movies of him doing his mouse stunt, but he was also finished courting for the day. However, I did get some, including a detailed exploration of his topography with a 4½ inch telephoto lens at a distance of 8 feet, under somewhat unsatisfactory light con- ditions as shadows of trees to the west were encroaching upon the field of view. (Also structural parts of the cage). In these tele- photos only a small part will show at a time, such as head and part of the neck, owing to the restricted field. As he was ex- tremely docile and unexcited, he unfortunately did not exhibit the colors of his skin patch. The mouse display, at present, follows this pattern, when that animal is given to him while he is in the cage: He takes the mouse, kills it without slapping it upon the ground unless it is a very large one. Begins display when it no longer struggles. This consists of raising crest, showing skin colors fully: blue, white and scarlet; bowing and facing to right, left and rear; hrooing softly; tail raised and wagged vigorously in more or less horizontal plane. He goes to inner cage, makes circuit displaying at intervals, comes out, passes magpies without dis- playing (one exception), comes west out of door, turns south, turns east and trots along south front of cage. If I am there, says: "Coot, coot, coot, . . . ." softly and rapidly as he passes me (only), turns north at corner, goes to mirror, displays for few seconds, then turns east, trotting along path 3 to 6 feet, stops, displays and so on for 10 minutes or so, when he takes it to either nest 1 or nest 2, where he stays for ½ hour to 2 hours. Formerly he went all over the country with it and carried it from ½ to 6 hours, calling at times. Now, no calling at all. April 20th. I did not see Rhody until 11:45, at which time I returned from a round of all of the nest sites, including those of last year, seeing and hearing nothing of the road-runner tribe. However, as I approached the cage at the time mentioned, there was Rhody just entering it with a bill full of nesting material. When he saw me, he came out, carried it up to the glass house and carefully placed it, crying as I approached. I suppose this nest will have to be called 4-36. Indications of the last few days are that he has resumed search for a mate abroad in the forenoons, although he has not been heard to sing, nor has he been actually followed to any con-
