(258) supposed Brownie opened her beak like a young bird and wanted it put down her throat. I then noticed that the tail coverts seemed to have grown miraculously in the last minute (Brownie is getting pretty thin there) and it occured to me to look at the eyes. It was Cheeky! This incident shows the stage in their development reached by the first brood. Cheeky soon retired to the chaparral outside the fence and no other young birds came. The centrifugal movement seems to be at present, at least, controlled by a more powerful force than I am able to exert centripetally. During the rest of the day I was able to feed the young thrashers in the glade only at such times as Brownie was busy elsewhere.

Neither bird returned, so after several minutes, I
