Weights of young pad-runners. The following weights were obtained with the kitchen scales, accuracy unknown and unguaranteed: Archie...........8 ounces, (170 gms.). Terry............6 " (227 "). Checking with a graduate reading in c.c. by bringing the pointer of the scales to the same indications, gave: 180 gms. and 240 " (The scales are at least consistent, as they gave 14oz. for both together). First unaided feeding. 2 P.M. Dr. Reynolds and Dr. Morse brought two dead mice and 8 live young ones with eyes still closed. One was offered to Terry, who was interested slightly. When it was laid down by him he picked it up from the floor of the cage, dropped it in the nest, picked it up again and swallowed it without assistance, using the "double shuffle" expertly. Not counting Archie's picking up gravel, this is the first self-feeding operation noted. While the three of us were in the shop yard with the road-runners running loose. A male quail came boldly into it and approached the box containing the young quail. Although he was frightened he persisted for a few moments, making alarm calls, then perched on the fence within a few feet of us and finally gave up the quest. The yard is only about 20 by 30 feet. Quail attacks R.R.'s. At 2:30 P.M. the male quail dropped down suddenly from the roof and violently attacked the young road runners (who were, fortunately in the cage) notwithstanding that it was within two feet of me. He ignored my presence completely until I chased him away. He struck at them through the wires with his beak and beat the wires with his wings, clearly meaning business. The youngsters were badly frightened. He paid no attention to the brood of young quail. I wonder if he blames the road-runners for their incarceration, or whether his action indicates a feud between the two races. If the latter, perhaps Rhody and his mate have been making inroads upon the local Quail population. Possibly, also, this indicates that road-runners are more numerous in this vicinity than is generally supposed Young quail taken in charge by male. This quail hung around the box all the afternoon. At 5:30, when he was up in a pine tree, the youngsters were released. They kept together and wandered off. The adult came down from the tree at once. He seemed to think that there was some trick about it all and kept his distance for some time, keeping about 6 feet away from them. Finally they followed him away into the cover, and were glimpsed a few times in the openings following his lead. R.R.s vs Quail. Mr. Robert Easton says that road-runners are shot around Santa Barbara because they destroy the quail. Evidently there are two sides to this question, even eliminating the matter of interference with Nature's balance. I have just witnessed an absolutely unprovoked attack by a quail upon two helpless and inoffensive young road-runners and the determination behind it is evidenced by the fact that the quail, in making it, overcame its fear of human beings in its effort to get at its quarry. June 19th. Terry had two of the baby mice for breakfast about 7:30 A.M. Archie wanted nothing at that time, but about 9:30 had one of
