(507) at the nest they would not touch them, suggesting that that reason might be that they had nothing to hammer them on. I did not record it yesterday, but B got another Jerusalem cricket Also Mr. Hopkins called in the afternoon to see the thrashers and Brownie, on the nest, after freezing at first, soon took meal-worms from him freely and fed the young birds. (Temp. 50, but warm in the sun). Birds getting more natural food. 6:00 P.M. (Temp. 60). The birds seemed to be able to get more food today. It appeared to be mostly cut-worms, spiders and grubs. Greenie had one load of what looked like meal-worms. I made up for any deficiencies by giving the adults plenty of meal-worms both at the glade and the nest. The young do not have their eyes open yet. Buffy feathers are showing on their breasts. They sometimes "nibble" at their parents' breast feathers. They can not swallow anything dropped into their mouths. The parents are frequently off the nest now at the same time. Appearance of young. G now more active feeder. Greenie at present is the more persistent feeder. This is another reversal in form. B's reversal pf form. Brownie frequently eats worms given him without offering any to the young. This is diametrically opposed to his behavior toward earlier broods. The night shift sleeps. 8:00 P.M. (Temp. 57). I stole up to the nest as quietly as I could, pointing the flashlight ahead of me to give warning of my approach in the event that the occupant was awake. The parent bird ( I could not tell which it was) was sound asleep with its head tucked under its back feathers, breathing slowly and regularly. It was just dome of feathers with no visible head or tail seen from the platform side and at a distance of about 18 inches. To see whether it was a bird or just a bunch of feathers, I went around to the other side and below and found that it did have a tail after all. What an easy victim for a cat! I could not see the mate.
