Consequently, at 9 A.M., Neo was undoubtedly maintaining contact with another thrasher. Julio saw this other bird and thought it was much larger than Neo, but this cannot be accepted as a correct conclusion because, as these notes have also repeatedly shown; there is an odd illusion which causes the nearer of two thrashers, close at hand, to appear the larger. At 9:40, Rhody still in his roost, I endeavored to ocular evidence of the presence of Neo's companion. Experience of 9 A.M. was repeated in every detail, but I saw no other thrasher--only a rabbit sitting quietly where the other bird "ought" to be! This time it was seen that Neo's irides are of the same color as Brownie's: a bright orange brown when in full sun. (This is not Ridgway's designation of the hue). At 10:45 A.M. (63°) Rhody still in his roost. Neo was in the sage patch and ran off hurriedly on seeing me, glided under the fence and began preening. I sat in a chair at the place where I usually feed him, with legs crossed, one foot about 8 inches above the ground. Neo kept on preening for about 5 minutes, then decided to come and have a look. He had not been talk- ing, and did not make a vocal sound during our interview, which lasted 15 minutes. I wanted to have him take worms from directly under my foot. This he did several times, each time looking up at my face before taking the worm. These notes have recorded it as a thrasher trait to look a person in the face as if realizing that some evidence of intention could be read there. At 11 A.M. Rhody still in roost. At 11:15 he was no longer there and could not be found, but in the process of looking for him, I flushed a Cooper (?) hawk from a low tree and, in another half hour, another (or the same) one. During this period no birds were seen out of cover. About noon I looked up Neo, finding him where expected: in the chaparral on the bank. In watching him coming to me, my glance happened to rest upon something stirring slightly in the brush. This proved to be Rhody, probably keeping out of sight of the hawks. Rhody was extremely reluctant to come out of the bushes, al- though plainly hoping for a mouse, so I got one for him to prevent his having to expose himself to undue hazard! This proved to be all he wanted for the day. Neo responded whenever called upon during the rest of the day and at times, took the initiative himself. At 3:50, on returning from an absence of several hours, Rhody was already in his night roost in the eucalyptus tree. He had re- fused offers of food from Julio while I was away. Another pellet by Rhody. I overlooked recording that, when Rhody revealed himself in Neo's domain, one of his first acts was to disgorge a pellet. This time I had a side view with back-lighting. R first arched his neck, lowered his head and opened his bill wide, made disgorging movements from "way down", shook his head sideways and it was done. As the pellet emerged, drops of fluid were scattered about by the shaking motion, showing plainly against the back-lighting. Rhody is still "off of" meat; it is days since he has touched any. This seems to be reflected in his increasingly frequent cast- ing of pellets. In now seems fairly safe to offer the generalization that, roadrunners on a diet consisting almost exclusively of mice, must cast pellets of their fur, notwithstanding the fact that most of the fur passes entirely through the digestive tract and is re- jected with the feces.
