Brownie will sometimes refuse the worm offered him. Greenie almost invariably does; though she occasionally takes one. 1:20 P.M. I have not heard a sound from either of them today as yet, though both are friendly. About noon, as I was filling the food dishes in the glade, I looked up to see Brownie facing me about 4 feet from my face, with wings spread and bill wide open. He jumped to my hand, and his feet felt hot. Between worms, he again spread his wings and opened his bill. (Temp. 67).
