Swarth, C.W. 1979 Buff-breasted Sandpiper Tryngites subruficollis Meade River, North Slope Borough, Alaska 7 June 5-10 displaying ♂ seen among the willows on the plot. They are spaced out about 50-150 m apart and quite inconspicuous except when performing various displays. The following list describes different behaviors and displays: Wing-up - the male extends either one (more common) or two wings (less common) vertically over its head with the white under- wings facing outwards away from the bird's body. The wing is always fully extended. The bird then turns from to side to side in an arc of about 90°-120°, lifting its legs and marking time as if walking in place. Every few seconds the wing is partially retracted, then flipped up again. This entire display is very effective at making the bird conspicuous among the brown willows. The tail may also be cocked up. Flutter-jump - The bird seems to be jerked into the air .5-1m as if pulled on a string; it throws its body upward while fluttering the wings briefly. It will do this 4-6 times in rapid succession.
