thing happens. 11:45 A.M.(Temp. 72). The adults are loafing in the glade, friendly and apparently perfectly happy. The young birds are in the shop, also happy. They sleep about half to three quarters of an hour and then ask for food. I give them a little at a time. There is not the slightest difficulty in feeding them at present. From the volume and appearance of the faeces, I am inclined to think that a very considerable portion of the food administered is not digested. This suggests that the parents' method of disposal of the waste is not dictated entirely by considerations further of sanitation. It may have a definite food value. This suggests that the parents may depend upon it in part for their own food supply, and reference to back notes will show, that, with earlier nests, the parents ate practically none of the worms given them, but, with this last one, Brownie especially, missed few opportunities of keeping himself well supplied from food intended for the young. The inference here might be that the natural food supply was limited, therefore the parents had a two-fold limitation imposed upon them, hence fell back more upon the food given by me. This, of course, is mere spec- ulation as far as I am concerned. 2:10. The parents remain friendly. Every time I have gone to the glade today they have been there. Just now they both hurried out from the bushes when called, B singing as he came. I'll bet that they are glad to have this affair off their hands! 6:00 P.M.(Temp. 68) Certainly as far as temperatures are concern- ed, there were no hardships thus far in the October--November breeding season. 8:30 P.M. (Temp. 69) Could not find either B or G in the nest tree or in G's first tree. This shows that, while they do occupy the same twig as a roost for many nights in succession, they do change.
