726 Pat back in cage. A little before 8 A.M. Pat was back in the aviary again and accepted worms offered. Neo was not in sight. Pat came out, worked on the base of the pine again, getting good results, then prospected around neighboring gardens. He soon returned and discovered Neo pecking thing out of a joint in the aviary woodwork. He sat on the wall above Neo and began to sing and display. When Neo attacked the pine, Pat dropped down near him, still displaying and singing and there was a spirited cock-fight for several seconds in which Pat seemed to be the aggressor. In was terminated by mutual consent, both birds working on the base of the pine tree for a time, then going into the aviary to dig and eat of the food there, Pat also singing and tagging after Neo more or less. I wonder if it is courting, or an attempt to assert territorial rights. Both birds seem perfectly contented, either in or out of the aviary, regarding it and the outside world, apparently, as extensions of each other. At the same time, the aviary seems also to be a place of refuge. So far, the experiment is working out as we had hoped, and other thrashers are also frequent visitors at the Reynolds place. Pat displays foe Neo. A fight. Pat sings. Reason? Attitude toward outside world. B day-roosting. 11:15 A.M. Brownie sitting in his night roost in the dormitory tree without a care in the world, singing and looking down at me benignantly. B planning? 4:30 P.M. Brownie in the same place again (not still). No amount of cajoling and display of worms could budge him. I suppose he is thinking things over and formulating plans for the future. Night roost. 7:30 P.M. A chilly breeze has sprung up from the north west, and B has wisely chosen to spend the night at his old roost in the dom behind the wind screen which was placed to protect the October-November nest. Bb seems to have found his regular roost untenable and can not be found. It is also exposed to north west winds. Bb changes roost. August 11th. Early song. A little early morning song. About 7 everything was quiet about the place and not a thrasher
