M.C.Russell M.V.Z., Berkeley, Calif. Feb 24, 1960 acc. 9767 (1) Send Pyramid Lake, Washoe Co., Nev. 13674 & White wing Scoter Found dead by Virgil Kay Johnson on Dec 23, 1959. Brought in to M.V.Z. by Ted Johnson. Bird very thin. Feb 24 1960 Returned to study area W of Tomales in afternoon arriving at 3:30 P.M. Intended to dig out some more & when they started their afternoon working. Day becoming increasingly cloudy in late afternoon. Has been no rain now for a week. At 3:30 found just a handful of fresh earth recently put up in what I call a & burrow system. Thought well here they are starting to work sight on time. However at 6 P.M. approached it was apparent that the general population was not going to be active, at least in throwing up new mounds. Found very little fresh work up to 9:30 P.M. when I left. When I would find fresh work, and never extensive, they were very slow in returning after I opened the burrow.
