him now, for many good and valid reasons, yet, on the other hand, it may be exactly the thing to do, scientifically considered, apart from humanitarian motives, as release from captivity would at once place both birds in completely natural relationship with each other. At 4:30 Rhody left for the orchard, dawdled about there preen- ing and watching the poor, down-trodden laborers on the house across the street starting up their limousines and driving off-- one man to a car--after 6 hours of gossip at $12 to 14 per day. He did not mind the accompanying sounds, some of which arose from a distance no greater than 25 feet from him; in fact I believe he was actually entertained by the activity and noise. By 5 o' clock he had gathered an audience of his own--bush- and wren-tits, towhees and crowned sparrows, one robin--slipped under the fence and trotted off along the sidewalk on the way to his bunk after a busy day without any pay, apparently happy and care-free. March 2nd. Rhody was first seen at the cage at 10:50, having apparently been on tour before that. R5, who had been tame and confiding up to that time, now concealed himself in the upper annex. Rhody stationed himself at a strategic point on the roof where he com- manded the most extensive view of the interiors of the cages, and sat there like a statue. This kept R5 from venturing forth as long as he was there. Rhody came down about 11:15 and I opened the cage door wide and gave him a mouse. He took it without display of any kind-- [illegible] and stood near me holding it for about 15 minutes. He then walked into the cage far enough to see R5 in the upper part, halted suddenly, pivoted at right angles to his former course, crouched, then turned and walked out. During all this time there was no display and no offer to R5. R now took a 10 minutes rest in the sun--R5 still concealed. The temperature in the sun was such that he used no form of sun- ing pose. (Temp. in court 64). He now began mildly to trace R5, gave up and went to his new attraction: the nest site in the tree at the glade. Of course he cried when I went there to look at him. At last he came down, got a twig, carried to the mirror and then to nest 2-36! (Which is also 1-37). However, about 12:30 he was working hard on the new nest, which is, then, 3-37. 2:05 Rhody has been working steadily at 3-37 and has a plat- form on which he can easily stand. He continued to work until 2:50, when he went to the cage. I had noted the path upward through the tree that he preferred and cut out interfering branches. He thereupon adopted that route to the exclusion of others, and used some of the smaller twigs that had been removed, for his nest. At the cage I gave him a mouse, which he again treated with- out ritual, held for about 10 minutes, carried about without dis- play, then ate. He now turned his attention to R5, as he did yesterday. I opened the cage door and R5 came out. R5 (at liberty) and Rhody R5 ran rapidly to the west. Rhody, with a handicap of about 25 feet by the time he saw R5, had him practically overhauled by the time R5 had travelled 35 feet. R5 dashed into the lath-house followed by R. They whirled about inside. R5 was out first. A short run and a long sailing flight to the south east with R
