Found dead in a Potter trap, apparently by a gated traps. At the same time 6 4/12 5/6 '31 was in another compartment, continued. Shuttled Jorkee A275.535. Caught in a Potter trap. Sail feathers all pulled out and scattered in front of trap. Bird lying on ground, inside trap. I thought at first it was dead. When I picked it up, could find no injury, but it squealed loudly as if in pain. I handed it, and released it; did not fly away, but walked off into the Busher. Was it merely nearly frightened to death? And what in- fired it? An apparent manner in which an animal could have entered the cage trap, and a cat would have knocked the trap over. This bird found a few minutes after finding Song Sparrow dead F17, 759 dead in another trap about 150 ft away.
