(316) (It will be remembered that the thrasher can and does continue its undersong while engaged in other activities). She caught yellow-jackets, dug, and pulled "dandruff" off of the stems of her new tail feathers. Most of the time she was sitting quietly giving all of her attention to the song. It was her sub-song, plainly audible at 50 feet (I used Julio to check this) and probably to be heard as far off as 100 feet by careful concentration; but this is a guess. For 5 minutes (approx.) of the time she sat 4 feet feet from my left ear and on a level with it, singing continuously. She then settled down for a nap in the same place for another 5 minutes, occasionally bubbling and talking with her eyes closed. All of her actions were without any hints or inducements offered by me and she did not come to me for food. She seemed very happy. At the end of 50 minutes I called her to me for worms. She sat on my bare arm, gripping it with her sharp claws, but could not stick there long, sliding off into my lap, looking me over curiously, finally dropping to the ground to continue as before. At the end of the hour and twenty five minutes, she heard footsteps on the road north of the glade, stopped singing, ran into the bushes and sneaked up the bank through them toward the sound with tail slightly spread, very much on the alert, crouched low to the ground, and peering underneath the branches. She saw that it was Julio, came out into the open at once apparently satisfied that everything was all right, trotted over to me for the worms which I offered her as a reward for her vigilance and when I left was again singing her undersong. She seems to be over the itching stage of her moult, for, today at any rate, she is bright and cheerful. 3:20 I have seen no chasing of Snooty today, though the three birds have been in the same general vicinity of each other in the open more than once. Once Snooty ran to Greenie with a worm, I now suppose for help in swallowing it, but Greenie had one also that he wanted to give the young bird. This created a problem.
