(479) Male takes night shift. Permanently(?) At 5:45 Brownie came back and took charge. I was interested to see whether Greenie would leave the tree or just shift to her new roost in Room B, same tree. I had to get a flash-light to find out. She was in room B. It appears to date, therefore, with this pair, and this nest, that the male takes,or at least starts, the night shift. (Temp.76; Sunset 5:30. Max. here today 88. This probably is unusual weather for this time of year and possibly unprecedented). (Not unprecedented). October 18th. 8:20 A.M.(Temp. 70) Morning calls. Considerable early morning calling was heard. Birds off. At 7:46 there were no birds in the nest, but the eggs were warm. G stole into it quietly, however, in less than a minute. She would not take worms. At 8:05 she called and B took the nest. I went to the glade and G came to immediately, flying up to my knee for worms although she had just frozen a few minutes before in the nest. At about 8:10 she was back on the nest again, which I determin- ed by going up to the platform. In this position my head is about: a foot from the bottom of the house and amongst branches. Immediate- ly there was the sound of feet on the perches in the house and B moved to a twig by my ear, looking curiously in all directions, apparently at nearby objects. He then began a systematic inspection of the house both inside and outside and all the twigs and small branches in it s immediate vicinity with only a casual glance or two at me. He peered up, down, sidewise and at all other angles as if looking for something, but uttered no sound, finally leaving. B inspects glass house and surround- ings. Former procedure departed from. The rest of the forenoon frequent calls where heard from the nest before changing shift. Contrary to the practise with the earlier nests, this has now become the rule, to which, naturally, there are exceptions. It seems strange that the procedure with the fifth nest should be so different from that of the other four. [illegible]
