very probably, within the last few hours. Hence the incubation period, with slight probability of error, was 16 days for each. This successful outcome now compels me to retract one of the alleged stated resemblances between N2 and Nova. At 8:30A.M. Rhody was perched in an acacia ( A. floribunda) near his nest. He has never been seen there before. On invitation he sailed down and came to the tool-house for his mouse, but by a route several times as long as the one I took. This gave him an oppor- tunity to cut a few more capers on the way to let off steam. Meal-worms too large for thrasher chicks? Neo proves they are not. Going back to Neo's acceptance of meal-worms for his brood: I find that they are too large for the youngsters, or at any rate, while I was watching Neo was unable to push them down the throat of any of the brood after trying each several times. He had prepared them on the ground just as Brownie did and took only two of the three given him. At 10:20 A.M. Neo has just succeeded in getting a whole worm down the gullet of one chick. I had been cutting worms in two for him; but he ate them all himself; so I gave him a whole worm, which he immediately took to the nest, where Ýé one chick swal- lowed it with little difficulty after Neo had pushed it well down. Neo leaves nest unattended to get food from me. At 11:20 I looked into the nest ( Neo there) and sat down 20 feet away. In a few seconds climbed up through the top of the honeysuckle and ran toward me with "blue-bird" calls. I gave him worms--two of which he ate. One was carried to the nest. In a few seconds he was back for more, taking another to the nest after extracting tribute. He had left the nest unattended. He now hovered the chicks. 10 minutes later the nest was unattended and Neo was seen running down the path. A call to him and he stopped, came back, ate two worms, took the third to the nest and remained there. N2 was now heard scrapping and soon mounted to a rose branch projecting above the honeysuckle 20 feet away, eyed me and continued to scrp monotonously as if objecting to my presence. This was true to her recent form; however, by being patient, I got her to see the light and come to within 6 or 8 feet of me and get two worms, which she prepared carefully and took to the nest, remaining there while N2 came out and got more worms from me which he ate himself. N2 objects to my pres- ence, but finally capitulates, following Neo's ex- ample. First sign of Rhody's moult? Meanwhile Rhody was flaunting about near the cage; so I went to see him. He paused near me, examined his feet, probing them with his bill, then scratched his neck, loosening a feather which floated away. First sign of the moult? Further progress in N2's learning. At 12:10 I looked into the nest: Both parents absent and no sound from either. I sat down a couple of yards from it and then saw that N2 was sitting quietly 4 or 5 feet from the nest, not apparently alarmed or resenting my presence. She probably also had seen me looking into the nest. I tossed worms below her and she got them and took them to the youngsters without any fuss about me. Rhody not singing now. nobody did not sing during the day, in fact has not been heard to sing since the act was last recorded in these notes. He also was not seen to work on his nest. However, at 1:30 he was picking up (and dropping) twigs near his old nest by the livingroom window ( No. ) but wooh-wooded on seeing me and began his search for a lizard a yard or two from me. I moved to the path below the rocks that support the earth for the magnolia, hoping Rhody would follow, as that is a good place for lizards and I wished to observe his tech- nique. There was a lizard there sunning on a rock and, sure enough,
