that mouse was distinctly second choice on this occasion. 3:10. This observation was incorrect: I find there was meat in his dish, but he pre ferred mouse instead of vice versa. Although the temperature is only as stated ( in the court) R pants in the sun and is cooling off now in the shade with spread wings. See how the road-runner adjusts himself to the cool coastal climate. Each of his spread-eagle poses was followed by neck-scratch ing as usual; then by general preening and casting off of loose feathers from the body. Rhody Leads Julio to the Mouse Habitation. At 4:30 P.M. I found Rhody lying quietly in nest 8-37. He began to cry on seeing me. He had used up all the supply of build- ing material I had placed on the road for him, so I got more for him, but as he did not some down for it and as I did not think that he wanted another mouse so soon after the big one given him at about 2:45, I returned to the house without paying any further at- tention to him. However, I had no sooner seated myself than I heard Julio, who was watering the garden near the nest, talking to R, so I went out and found J starting for the tool house and R following. I called to J to stop and let R show him the way to the mousery. This had not been tried before. I wished to find out if Rhody would do it with Julio, and if so, witness the action as a spectator instead of as a participant. R stopped when J did, about 150 feet by road and path from the door of the tool house, the route to be followed containing one reversed curve. I told J to wait and let R take the initiative. R passed J and stopped 10 feet in front of him. J was instructed to move up on him and was told that R was really waiting to see if he would follow; which was true, as he moved on a few feet, looking back at Julio and waiting each time that J stopped. Julio had not had this ex- erience with Rhody and was afraid that R would think he was being followed for some ulterior purpose and become frightened, so J kept stopping--R following suit. I explained to J that R wanted to be followed, that he would lead the way to the tool-house and would wait there for J to get him a mouse, but that he would step aside off of the path to get out of J's way when the door was reached and then step back again and wait for the mouse. And that is exactly what took place, to the tremendous delight of Julio, and I must admit, to mine. R took this mouse to the mirror to dis- play there and I came in to make this note without observing fur- her action. At 6 P.M. I stopped at his roost tree as I was about to drive by and could not see him, but when I called, he stuck his head out of the nest-house and cried as long as I stayed there. R's moult. Rhody is becoming progressively more ragged. When he was in one of his spread-eagle poses on top of the cage this afternoon and I could see the under surfaces of both wings, it was seen that there was a loose flight feather under his left wing. It seems probable, therefore, that he will be losing wing and tail feath- ers shortly. May 12th. Rhody was invisible at 7:30 A.M., but at 8 he whined at me from his nest 8-37. I picked up one of his tail feathers from the road beneath the nest: the first shed this year. ( It appears to be [illegible] one next to the middle pair of rectrices; but it will be necessary to have a good look at his spread tail before I can
