The siskins, incidentally, were causing quite a commotion. at 5:40 P.M. the ♂ flew to the nest, fed one youngster, than flew north from the nest with something white in his bill. at 5:41 P.M.

He was about 2/3 the size of a grown Robin, with a brown back, a tawny breast, very speckled with dark spots, at 5:43 P.M. the ♀ returned to the nest, feed a youngster, then settled down on the nest facing north-east. at 5:46 P.M. one of the youngsters disturbed the ♀ by pushing its head up against the wing of the ♀. at 5:49 P.M. she stood up in the nest a few moments, then left the nest, landing on the lawn about 100 feet east of the nest.
