1006 Archie is still the larger bird in appearance, and today, demonstrated that he is quite an accomplished and easy flier within the limitations of the cages C and B, flying with little appearance of effort even around corners, and easily ascending to the greatest height that the cages afford: about 8 or 9 feet. These flights seem to be exploratory. Terry flies little and with difficulty. He is much weaker than Archie. Archie handles a live mouse without difficulty, killing it easily. Terry's blows and slaps lack force. He has more of a struggle and does not make it a sporting episode. On one of Rhody's returns both tried to get out to him. R posed for them just as with the magpies. R at close quarters, especially in a slanting sun, is really a beautiful bird with his blue, green, bronze, copper, black, white and tawny plumage and red, white and blue patch back of his eyes. He seems to have been recently refurbished. In a "spread-eagle" pose on the ground today, lasting for perhaps ten minutes, he was really a splendid creature. The two youngsters stared at him in admiration fixedly. R, I should say, is one third larger in all linear dimensions than his offspring. (Theoretically this would make him about 2½ times as heavy). When he came to me for meat the last time today, he used a new note, almost a chirp--the first time heard. July 12th. B sub-singing. Brownie seems to have initiated a cycle of sub-song; at least as I sat in the R.R. cage this morning, he sang thus continuously for a long time. It is the first for some weeks. B moulting. He is getting a new suit of clothes and looks somewhat mangy. He is sprouting new tail feathers. When Rhody arrived at the cage for meat, Terry emitted a loud, adult rattle-boo, but did nothing about it. (9:30 A.M.).
