It did not lead up to full song. About 7:15 B and Bb were in their night roosts. I do not know where Nova and Nb roost, or even if it is on the property, though both are seen occasionally. I have seen no determined chasing of the young birds as yet. They both forage for their own food supply as capably as adults. Bb catch- es bees and handless them apparently with full understanding of their offensive powers. He goes about entirely alone. July 31st. B again opened the day with full song. At breakfast time Bb was playing about the dining room windows, all alone. He had a riotous game of hide-and-seek with himself about a dwarf azalea and appeared to find plenty of food in the lawn and shrubbery. This is the territory seldom used by the adult thrashers; although Brownie appeared shortly and there was a minor threat, but no serious action. About 9:30 A.M.

Bb set himself for battle instantly with open bill, crouched low to the ground and making harsh noises, then ran off making his infantile call which is given after leaving the nest. He remained in
