Age of A and T. The young road-runners are now six weeks old (plus or minus two days). Eye patch. The coloration of the eye patches on both is the same. It ranges from deep, dark blue over the eye, through turquoise into white and then to apricot. The latter was last noted as saffron, but it is now warmer. There is very little pure white, unlike Rhody's patches. (Colors not referred to any chart). Feeding. A and T will not or can not feed themselves except on living things or small creatures recently killed but retaining their original forms. Even the latter they wish handed to them or wriggled about. They will not pick up meat for themselves or any of the food mixtures placed in dishes for them. Rhody and young. At 3:30 P.M. Rhody came running up to the cage swiftly while I was in it with the young birds within a foot or two.

He trotted slowly back and forth along the wire, following them as they moved correspondingly, repeating a high-pitched, aspirated sort of kerk. (It is impossible to describe). Also a low, hoarse whank. There was something duckling-like in the former and goose-like in the latter.

I doubt if he recognises the young birds as in any way connected with himself. His attitude toward them on this occasion seemed to be one of great curiosity mingled with caution and a certain amount of fear. At 4:30 Rhody again came to the cage, looked at the young-
