Cogswell 1950 Julia americana June 27 - Little Washoe Lake, 5020 ft., Washoe Co., Nev. - 50+ seen on marshy S arm of lake. About 10 NESTS were inspected, most of them floating and attached to the sparse emergent tules in knee-deep (to waist deep where Julian Twining went) water. Two were at the water's edge on the open shore. All were made of partially dry tule stems & contained from 3 to 11 eggs. No young birds were seen. July 12 N. end of lake, only, was visited. There were about 30 birds scattered among the more numerous Carel brebes; 3+ NESTS with eggs of the Coot were found. July 26 The NESTS found on June 27 in the S arm were mostly abandoned - some undoubtedly because the receding water level left them exposed, but there were 3+ still floating among tules which contained old eggs. Aug. 6 N. end Washoe L., 5010 ft., Washoe Co., Nev. - In the few pools (not over 5 A. in max. extent) left in the drying marshes NW of the lake there were about 70 Coots, including several juvenals. Aug. 9 Little Washoe L., 5020 ft., Washoe Co., Nev. - About 20 individuals seen, including a few in gray-breasted plumage of juvenil. The S arm of the lake is now nearly dry. Aug. 23 Est. 400 present on the lake, which is now a mass of Potamogeton, Polygonum amphibium & Ranunculus. Evidently Coots are migrating.
