(300) 9:20 A.M. Took panorama,with the last ten feet of film, of the vicinity of the oval lawn. 20 mm. lens set at f8, 25 ft. Greenie and No.4 were in the picture on the far side of the lawn. No.4 lying down in the sun. 11:30. No further observations in the interim. All three birds at or near the oval lawn.

A black cat, eating out of the thrashers soft food dish. True to form the thrashers held an inquest. They did not fly when I shot and the scripping has ceased. No.4 had been sleeping on the ground a few hours before a couple of feet from this spot. I believe that the disappearance of No's 5 and 6 is undoubtedly due to cats. July 27th. 8:30 A.M. At 5:30 A.M. a thrasher was singing near the oval lawn--nearly full song. This is the third morning in succession at about the same time. At 7 o'clock all three birds were at the lawn. At 8 o'clock, Julio reported three skunks in the tool house when he
