Cogswell 1950 Capella gallinago delicata June 25 - Sierra Valley Ranch, 4890 ft., Sierra Co., Calif. - In the broad wet (0 to several ft. of water) pastureland of this valley, we finally traced a mysterious "woo- woo- woo- woo- woo- woo- woo- woo" call to the Wilson's Snipe - in "nuptial" flight. It was first heard at 1 mi. N Battley, where 2 were flushed from the wet sedge-grass area. Here at the Macmillan Ranch we waded across a mile or so of marshy ground and had a snipe circling about us at about 250 ft. altitude. As it circled counterclockwise it alternately rose and fell gradually in altitude in an up & down sine-curve course. On the down slopes it "poured on the steam" and the whinnying sound emanated from its direction. This performance was continued, with but slight interruptions of the noise-making, for fully 10 minutes. The downward parts of the flight (a hence the noise) came at about 6 to 8 second intervals. 2 other snipe were flushed in this same area, over which the performing bird was describing a circle of perhaps 1/3 mile diameter.
