897. To top offthis meal he went to the cage and got meat, watched the magpies and rail as usual and made felts at the former from the top of the cage, climbed the old oak where B was singing. This caused B to leave, but he soon returned and sang while sitting about 6 feet from R. He then moved about 20 feet farther away and contin- ued his song. This (or something) aroused R to sing also, for 15 or 20 minutes. R then came down and acted the clown among the bushes, tearing about in wide curves, booing and playing hide-and- seek on opposite sides of bushes with an imaginary partner. He soon subsided, and for the next couple of hours was as unexciting as an old hen. 9:00 P.M. Brownie is sleeping quietly in his nest in the dorm- itory tree. I did not see him go to the new nest at all today. Feb.20th. A misty rain fell at intervals throughout the forenoon and part of the afternoon. This did not interfere with Brownie's csong. Rhody did not sing during the day at all. I found him in the cage about noon devoting most of his attention to the rail on the other side of the wire and ignoring the meat. He was following the rail as the latter moved back and forth near the wire, posing and displaying. The rail appears to reciprocate the interest to a certain extent. The mirror problem has now become much compli- cated for Rhody by the action of the rail in disappearing behind it as R follows him. R is intent on the rail and suddenly finds that it has disappeared and right where it should be there is a road-runner staring him in the face and touching bills with him. He stares at his reflection, pecks at it, then with a quick shift, looks behind it and the road-runner that he has just seen has changed into a rail. A "pulled" peck, and the rail moves off par- allel to the wire (and to the mirror which is leaning up again(it).
