1188 known to make this attempt and no pellet of his has ever been found. RR pellets. During A and T's confinement in the cage but 10 pellets (9 only recorded in these notes(?)) were found. This indicates that they represent accumulations over a long period of time and that these birds do not customarily reject the indigestible port- ions of their food at frequent intervals. It suggests that regurgitation with them is a matter of things not going just right. R "off of" mice. During the rest of the day Rhody continued indifferent to mice, preferring meat. May 21st. R on chimney early. At 6:45 A.M. Rhody was on the chimney booping. About 7 he accepted a live mouse, killed it, but deserted it to watch the magpies. At 8 he had still not touched it, being then occupied in oiling his feathers while still in the cage keep- ing an eye on the magpies. There are three young thrashers. To my surprise, I find that there are three young thrashers in Brownie's nest--a record for Nova. The error in reporting only two is due to the fact that the nest is the first one that I have not carefully examined. While it is only about six feet from the ground, there is such a mass of twigs and foliage about it that it can not be seen into easily. B cross at nest. 11:10. I have cleared head-room about the nest and placed a box to stand on. Nova, with a cricket in her bill, scolded from a distance of from 6 to 20 feet. Brownie came and cover- ed the youngsters, who squealed when they saw me for the first time. B was rather cross and would not take worms from me, open- ing his bill, threatening, but not pecking or shrinking. I have visited the last few nests very seldom, so perhaps Brownie has forgotten his former acceptance of me as a factor to be consider- ed in the nest stage. On the other hand, it may be that the brood was well fed at the moment. Previous experience has shown that he turns to wood when that point is reached in the feeding. Wear on thrasher bills. About a week and a half ago it was noticed that B's upper mandible was considerably shorter, nearly one eighth of an inch (3mm.), than the lower. Now it appears of the same length, or perhaps even a shade longer. At the same time it was noticed that Nova's lower was shorter than the upper by about the same amount--just the reverse of B's. I could not see any difference just now, but the opportu- nity was unfavorable. (While writing this note, Brownie, as if regretting his attitude at the nest, has come in here for a worm. He slips on the tile floor).(Rhody slips, but Terry did not). (B comes into this room). Slipping. Age of thrasher brood. Brownie and Nova's new brood is about two weeks old--prob- ably 15 to 17 days old. They rise en masse when one of their parents approaches. First brood gone? The first brood of the year has not been seen for several days. B tolerates me at nest. 1:15 P.M. Just now at the thrasher nest, Brownie, who came to it promptly when Nova warned him of my approach, was pleased to take worms from me and hand them to the youngsters. He had to tap each with his bill to make it open up. B's saliva flow. His flow of saliva was strong. Looking sidewise through the opening of his bill as he held a worm in the tip, I was surprised
