1471 They are tolerant of each other, but sometimes have mild combats in which Chiisai is the aggressor usually. Okii merely defends himself, holding his ground. C may take up fighting post- ure for an instant; then it is all over. It is only in the last three or four days that they have been able to maintain balance on one foot. Now they can do it well. Rhody likes to watch them and often spends an hour or more at the cage, close to the wire. Rarely he makes a short feint at them. When he first appears they scold a little, but soon calm down. Okii walks stiff-leggedly in his presence as Brownie did. Curiously, they disregard the magpies, even when those birds are only inches away, though on the other side of the wire. Although they dig and forage incessantly, more especially C, and there is soft-food available at all times: also ant eggs, they still have to be fed regularly with the "squir t gun". If very hungry they sometimes quiver their wings, but not often. Rhody continued as usual: no singing. However, for the first time in many weeks, he was seen sunning at his old post on the west lot in the early morning. Today (12th.) he followed to the tool-house three times, but only the last time did he accept my offering (5:15 P.M.). Ritual followed. The thrushes have two eggs now in their new nest--the first time they have been able to save one for more than a day. Perhaps removal of the owls had something to do with it. The eggs are laid about 10 or 11 A.M. The birds have not been seen to visit the nest in the afternoon. June 13th. and 14th. The thrush laid its third egg on the 13th. and, for the first time, the nest was occupied in the afternoon also, as if incubation were beginning. Perhaps the eggs laid (and stolen ) from the first nest are considered by this bird as still contributing toward her debt to society, and the batch in the present nest will, there- fore, be sub-normal in number. On the 14th. the nest was occupied all day. Rhody, during this period, with one notable exception, ran ture to form. The exception occurred when, on the ground below nest 8-37, he was invited to follow to the mousery. On the way he picked up a branchlet and carried it beyond the point where he should have changed course to complete the mouse-eating pat- tern and took it up to his nest in the glass house in the dorm- itory tree. I watched him place it and, when he came down, he pick- ed up another one. Naturally I expected him to take it to the same place, but he now ran west around the house (about 100 yards) and put the twig in nest 8-37. Thus, twice, he took a twig from the vicinity of one nest and carried it to another nest, but worked on both nests.(June 14th.). The young thrashers spend the daylight hours in the large outer cage and are placed in a small cage and taken indoors for the night. For the last three or four mornings it has been noted that there were green droppings on the floor of the cage, and these were traced to Chiisai, the runt of the brood. He has also ap- peared somewhat "soft", less tolerant of Okii and more restless at bedtime. His food was changed (I.e.: his hand-fed food) to the egg custard,
