Roadrunners, p.3. Repeated examination of droppings (not made with scientific rigor, however) have failed to show a single bone from the several hundred mice eaten by Archie and Terry, nor any feathers as a result of Rhody's eating sparrows given him. Mouse hair does appear in A and T's excrement and pellets are some- times disgorged by them, although but 8 have been found, consisting apparently entirely of mouse hair, in their cage in about 8 months. It would appear that such pellets represent an accumulation of a very considerable period of time of such hair as failed to pass through the digestive tract. P.32, last par. In completely denuding hairy caterpillars, leav- ing them smooth worms, is this the habit of the cuckoo? P. 36, Lizards. Lizards appear to be Rhody's favorite food. He not only stalks them aware of their presence, but deliberately hunts for them in places where experience has taught him that they are likely to be found, and, moreover, when shown one in hand, exhibits more live- ly interest than in any other kind of offering. Un- less very hungry, he does not kill them at once, but places them on the ground, pretends not to see them, walks around them and waits for them to bolt. He plays with them. Curiously, the blue-bellied lizard, even when uninjured, makes no attempt to escape while in the bird's bill, nor for that matter, does it when placed on the ground for an indefinite length of time. The alligator lizards show fight. Both are invariably swallowed head first, as are all other creatures, whole. P. 37, Snakes. No limit of size eaten has been determined here. Rhody swallows 14 and 15" inch gopher snakes but it takes a few minutes and then he has a "stiff neck" for several minutes after. Yellow bellied racer and gopher snakes 2 to 3 feet long, when found by him are variously treated. That is, they merely glanced at and ignored, watched curiously, followed through the grass and bushes at a discreet distance or actively chased. In the latter case, sometimes until it escapes through the wire fence whereupon interest is lost. In no observed case has he actively attacked a snake longer than 15 (measured) inches in length. Such snakes are also played with, like liz- ards. Some of the small gopher snakes fight and strike at him furiously. This gives him no concern. When they strike at him he nonchalantly plucks them out of the air by the head with unfailing precision and whips them on the ground, letting them go for another chance. When tired of this, he gets down to business, whirls them over his head and slaps them unmercifully upon the ground until they are dead. I do not think any snake, except by chance, could actually strike him. A small rattlesnake un- doubtedly would be treated as any small snake. A large one would probably not be attacked at all. (Curiously, Rhody catches small snakes only by the head; whereas Brownie, the California thrasher,
