Oct. 14 El Batel, 70 km. NE Mayatlan, 5100 ft., Sinaloa Stayed in camp today because of illness — another attack of Bacillary dysentery, apparently. Collected an Empidonax flycatcher and Cathartes mexicanus in camp. Of the remaining specimens prepared, the large Amphila and the Steller jay were collected by Russell; the small Amphila, the woodhewers, Certhia, the small green and yellow, red-capped fringillid, and the Scott Oriole were collected by Leopold; and the Caloitta, Balonophygra and Strix were collected by Alberts. He obtained both the jay and the owl below camp; the jay occurs around the borders of the cleared lands, Virgin. The owl was obtained in a dense stand of trees Oct. 15. Stayed in camp again. Of specimens prepared, the Empidonax was collected by Leopold; the jays include specimens collected by Leopold and Alberts.
