then prepared 5 very carefully and went toward the nest, but stopped half way. I went to the nest, finding G giving the youngsters the batch of worms just received from me. She then left, so I was at the nest alone, apparently without causing the parents concern. B did not come, but G returned in a minute or so with grubs and we then gave the young birds all the worms I had, almost all of them going to but two of them. On returning to the glade, I found B there preen- ing after a bath. G came for another worm for the young. I returned to the nest and B came in leisurely fashion, sat on the edge and watched me handle the youngsters, without the slightest concern, right under his bill. The first worm I offered him he ate himself. He then gave the youngsters two and, when I left at 8:45, he was sitting there looking at things. At 9:45 A.M. when I went to the nest, no adults present, B appeared shortly, but took his time about coming up. When he arrived he made a careful inspection of young and nest, much as a watchmaker inspects a time-piece with his eye magnifier. He then waited patiently to see what I was going to do about it. The youngsters called for food, but he had none. I gave one of them soft-food, B picking up the crumbs and, by his manner, tacitly approving the procedure. When I offered worms, he served them properly, but exacted tribute. It looks as if this bird realizes that there is no necessity for him to go out and hunt food as long as he can get it from me. This conjecture is sup- ported to a certain extent, by the fact, that, with previous broods, he practically never ate worms as long as the brood needed food. Now he eats them often before they are fed, as if he knew that there would be no resultant shortage. The conscientious Greene, on the othe hand, continues to forage diligently and also gives all the worms that she gets from me to the young, practically without exception. Incidentally she is now a constant applicant for worms, directly counter to previous behavior, although still shy.
