looking. The pupils of the eyes of these young birds also show the same fluorescence or "bloom" as noted with the young of nest 5. It is very striking. The parents' eyes do not show it under exactly the same conditions of illumination. I have repeatedly made the comparison at the nest. Ins and outs. At 6:00 P.M. both birds were still in the nest. One of them has been out of it repeatedly, returning each time without wandering more than a foot away among the surrounding twigs. Once again he was heard to give his kip call when out of it. Once also he crowded ged past Brownie on his way out, B not even turning to look at him, returning voluntarily for more food and a nap. I have once or twice suspected that food is given more sparingly when it is considered about time for the young to leave, but have no confirmation of this. Parents do I have never seen any disposition on the part of either parent to leave. either to force or induce the young to leave the nest. Fascinating tameness in nest. The little fellows are very tame, like to be "hovered" with the hand in the absence of B and like to have their chins rubbed, closing their eyes complacently with "drowsy tinklings". They have shown a disposition to peck at particles of dropped food. and pick objects off of each other. Gullet smaller? I think their gullets are becoming smaller, judged by appearance and by the fact that the tube of the "squirt gun" does not go down so far; also B now, occasionally, makes a miscue in feeding. crumbs, B's splendid housekeeping. B continues to keep the nest scrupulously scavenged of all drop- pings, oak leaves and catkins. He does not confine his attentions merely to those which happen to attract his attention; he searches for them and even occasionally rearranges portions of the nest struct- ure that have become displaced. A fine housekeeper and parent.
