About an hour later, on returning to the glade, the smaller and lighter bird went through a similar performance, but was a little more frightened on being unable to find the door. This attracted B's attention and when the youngster went out the door, Brownie chased him entirely out of the glade, repeating the performance noted on the first day that the young were out of the nest. I think also that it was the same bird, Cross-patch, though this name no longer is appro- still priate. I think it is the female and that, on both occasions when B attacked it when it was in distress, it was a manifestation of the strong bird attacking the weakling. This is purely tentative. On this occasion the punishment was not severe. Later this young bird returned, not seeming to associate the cage with his recent experience in any disagreeable sense, and ate freely from my hand, walking up on it. When the worms were gone he tried to peck pieces out of my palm. A couple of hours before when I would not let B get at the worms in the box, he hammered me hard on the backs of the fingers, but the pecking of the young bird, on account of the sharpness of the bill, seemed about as severe. April 24th. Roadrunner 9:10 A.M. The Roadrunner (or one like him) is back cooing in the garden now. No thrasher eggs. B in full song. 9:45. Beginning at about 9:15 B was heard in full song and he is still at it. Nova in the nest and B changing position from place to place, sometimes singing within 20 feet of the nest. I think he has hopes. Occasionally he has stopped to see what I had in the way of food and to worry the youngsters. During this period, also, I have observed the roadrunner, who is not very wild, and tossed him bits of meat which he has seen fall near him, but not taken. He has picked up bits of paper, carried them a short distance, and dropped them. Reaction of other birds toward R.R.
