off in the air in surprising large quantities. For some reason Greenie seemed to take a special interest in this capture and was disposed to demand his share, but Brownie, after settling the matter by swallowing the butterfly, aimed a substantial peck at Greenie and he retreated. When Brownie moved elsewhere, Greenie went to the place where she had hammered it on the ground and examined the spot carefully, stirring the earth with his bill. Vibratory head motion. 1:40. For the first time I have just witnessed the rapid, vibratory movement of the head and bill, previously noted in connection with these birds, put into operation with the bill inserted in the earth . Its object was obscure. Arboreal antics. Brownie has been sitting in a tree using the bell motive in her occasional soft calls to Greenie on the ground below and Greenie has been running up to her at intervals, both of them then opening their bills making various sounds--some of them harshly sibilant.
