(539) fairly 15 to 100 feet, with frequent imitations on occasion. S's thirst perpetual. The younger has an almost perpetual thirst, taking water in preference to food frequently. I have decreased the amount of salt in the custard and am giving him a greater proportion of meal-worms, with their hard heads cut off, and lots of water. Extraordinary patience and trustful-ness. His extraordinary patience under manipulation is remarkable. In removing encrusted food from about the eyes, particles of lint and -ball filaments of down from off the eye, using camel's-hair brush, tweezers, soft cloths, the fingers and even scissors to cut off the ends of feathers that have become distorted and curled over into the eye, I can count on his keeping his head perfectly still without holding it. B&G's ear covert moult. Brownie and Greenie now have their new ear coverts practically finished. In this, as in other phases of moulting, Brownie has been the more forward bird. At present, at least, the new coverts are lighter in color than the old ones, giving the birds a changed appearance. Dec. 6th. B&G excited on seeing S. I took the young thrasher down to the glade and held him in one hand while Greenie and Brownie came for worms. They were a little excited by his presence, but did not offer to feed him. He was per- fectly indifferent to them, as parents, but showed interest in their going and comings as he does toward all moving objects. S sings. About 1 P.M. he was very comfortable in his box in the sun and essay a comic little thrasher song--mostly low warblings--with one distinct wheet-you. The effort caused him to bob about just as his parents do when they also sing lying down. Curious that he should sing when he can not stand, walk, fly, perch, scratch himself, pick up things with his bill or even eat and drink without assistance. He can, however, preen, although he falls over on one side when he does it. He does not recognize food or water as such, but he tries to catch flies Does not recognize water and food
