Roughneck eats cereals. and cracked corn and wheat at one of the feeding stations, spending several minutes eating there. This was from choice and not because other food to his liking was not available. September 7th. Thrashers singing. Usual early morning song by B. He also resumed sub-song during day. Other thrashers singing in the distance as late as 6 P.M. At that time B was listening to them and calling: Queelick from a pine tree. I escapes but is caught. Julio informed me that Terry dodged past him and escaped to the outer world yesterday afternoon, going on top of the cage and elsewhere, much interested in things. He was easily caught, but squealed at first. New sleeping place for RRs. A new sleeping place was made large enough for one bird in the south east corner of cage B. A and T came frequently to inspect, during construction. Terry was especially interested and once got on top of my bare head and insisted on staying there and stamping his feet while I was working. This is a peculiar practice of his which has been noticed fairly often. He gave an especially good exhibition of it on my cousin's head (K.D.) which was witnessed by Dr. Alden Miller and myself. The reason for it is, as yet, obscure. actually It may be a preliminary to dusting, an act performed by Archie on my head, or a sex manifestation, as it appeared to be in the case just cited, observed by A.M. and me. Terry also insisted on sit- ting on th hammer when I was about to drive a nail. When the job was finished he inspected it minutely. Going to bed. About 5:20 Terry was going in and out of the left-hand room of the sleeping quarters, the one that caused the trouble 24 hours be- fore. Archie was wandering about irresolutely but aware of events. Terry quit this and kept away from the place until about 5 :40. At about 5:30 Archie made up his mind to go to bed and went directly to the right hand apartment (not the preferred one) and spent I stamps on my head, an unex- plained act.
