On second attempt Terry was able to master a very lively lizard handed to him. The first time he allowed it to escape from his bill. He swallowed it in one gulp without apparent effort and without trying to kill it. In a case like this I am inclined to think that the lizard really commits suicide by darting down the first opening he sees when the bird has turned him in the right direction. Archie continued to collect gravel and miscellaneous articles at intervals. June 21st. About 7:30 A.M. the young road-runners were still in their nest in the small cage. They seem to be late risers like Rhody. Perhaps this is a family characteristic. About 8 A.M., when released on the ground, they wanted to get up in my lap and were accommodated.

As I shall be absent for a week or two, I have arranged to have Donald Brock, during my absence, spend some time with them each day and supervise their feeding. They are already on friendly terms with him; one of them,
