(254) formances when the first batch of youngsters were still very young. As they grew larger, as shown in these notes, "preparation" of the (today) worms ceased. It is now renewed for the first time. I neglected to note in connection with this morning's last chase that feathers were also "drawn". Brownie has a broken wing feather now and it seems that this business of tearing through the bushes after birds as big as ones self has its hazards. 5:10. I have just inspected the contents of nest No.4. Greenie was in it and would not get out voluntarily, so I put my fingers under him and lifted him out. I wanted to use a mirror so I could get visual evidence, but Greenie insisted upon sitting upon my hand and obstructing the view. However, his feet and legs, being on the back of my hand, were readily accounted for and I had no difficulty in segregating three fairly big, fuzzy lumps in the bottom of the nest, so that there can be little doubt of another perfect score. Greenie pecked the back of my hand a dozen times, but they were very light taps and, as I withdrew it, took the end of one finger in his mouth, plumping down into the nest instantly. A very fine bird with courage and forbearance. Julio, who steadied the ladder, is more impressed with the birds' allowing themselves to be fumbled under, than with any other of their characteristics. He admires them immensely. July 4th., 7:35 A.M. I searched for 35 minutes for the young thrashers, but could not find any of them. The parents must have made a very successful effort earlier this morning. At 7:00 neither of the parents was on the nest (No.4.). I called and Greenie appeared, going direct- ly to the nest, then Brownie answered from some place hidden from view and shortly got worms from me, which she fed to the nestlings, Greenie going off foraging in the canyon to the west, Brownie remain- ing on the nest. 8:40. At 8:15 I went to the glade to see if it might be possible to put the brakes on to the centrifugal influence of the parents.
