1685-A Not a thrasher was seen or heard by me during the day, though absence during most of the afternoon renders the observation in- complete. May 29th. Neo discover- ed in nest 3. Beginning of regular incubation with changes of shifts. At 8 A.M., Rhody in his house; Julio watering the garden near thrasher nest No.3. I said he had seen no thrashers. I look- ed into the nest. Neo was sitting calmly in it! I had about de- cided that he had gone elsewhere for good. A hawk sailed by in leisurely fashion with a bird in its claws. At 9 A.M. he was still in the nest. At 9:30 N2 ( or a bird with a long tail) was in. Incubation appears to have begun. 11:30, Neo in nest, and nest has been occupied continuously. It looks as if these birds had "put one over on me" and somehow or other have at least one egg "without warning". During the rest of the day there was no time when a bird was not occupying the nest. Occasional calls for relief were heard. Rhody continued his present form, the most conspicuous feature of which is almost continuous occupancy of his nest 1-38 in the house, with short absences for mice, play with magpies and sunning; temperatures (over 65) justifying use of the spread-eagle posture always followed by vigorous neck-scratching. Rhody's moulte. (First tail feathers). Rhody makes error in selecting lining. Three days ago I found one of his rectrices--the first found of the season. When he was sunning today it was seen that he has lost two; the two outer ones, i.e., the outer one on each side. He displayed for only one of the two mice given him to- day. His "roosting time" could not be distinguished from his "in- cubation" period--he merely continued to stay in the nest. He conceived the idea today of using a spray of the fine leaves of the eucalyptus, which can be reached without leaving the nest; but he neglected to detach them from the tree. With great solemnity he pulled them into the house and carefully pressed them into the interior of the nest, but when he let go of them, the spring of the branch pulled them out again. He made a second attempt with the same result and then abandoned the effort. (Had he learned as quickly as this that it was futile, or was he too stupid to break them off?). May 30th. and 31st. During this period the thrashers continued incubation diligently. They are very quiet now and are seldom seen except in the nest, rarely coming for worms. Rhody maintained his present preoccupation with his nest in the gum tree, as last recorded. He appears to be permanently in his house for the night before 6 A.M.; but, as stated, his "incu- bation" and sleeping periods can not now be distinguished. June 1st. and 2nd. No change of note in thrasher and road-runner daily activi- ties. Snakes are now more numerous in the garden and, on each of these days, Rhody discovered one. The first was small enough to serve as inspiration for display at various reflecting surfaces after having been slapped effectively on the rocks. It was carried to
