Maclee 1969 (12 June) Good sketches of these. I was watching both birds feed quietly, ca. 30 m. apart. Suddenly the ♂ felt horny. He flew to the ♀, waved a wing, and then went into a tail-cocked, forward posture while still holding the close-side wing up. He then dropped the wing and immediately went into the nest cup. This lasted only 10-15 sec. He got out and the ♀ entered for <5 sec. She got out and flew ca. 15 m. He followed, and copulation immediately ensued. It was a long copulatory sequence, and appeared to be successful. Both birds then preened and resumed feeding. 13 June A great deal of very prolonged aerial displaying, both over Britton's area and, particularly, over Voth-Cakeester area, sensu latu. 14 June Again—by far the noisiest sandpiper. Birds are displaying constantly. Saw one chase over flar SE of Voth Crossing that involved 5 birds briefly, then broke into 3 and 2. They keep giving the impression that there are lots of ♂ but too few ♀. 16 June Still the only actively displaying sandpiper. They were abundant on the extension of Gasline Ridge, as on about
