. Die Vögel von Wyoming . Migration. Grinnell hat die folgende Anmerkung: Seenon Yellowstone See im August. Ich erwähne diese Art mit Aquerie, denn obwohl ich sie für mich selbst zufriedenstellend erkannte, nahm ich keine Exemplare. Es gibt ein schönes Exemplar in der Sammlung der Universität, das am See Desmet aufgenommen und von H. A. West präsentiert wurde. Ich habe ein gutes Exemplar gesehen, das im März 1898 in Huttons Lakes aufgenommen wurde. 166. Oidämie perspicillata (Linn.). Surf Scoter.Accidental; extrem selten.
