JPMayers 1978 Plovialis squatarola Atkasook on the Wlenda River, N. Slope Borough, Alaska 28 May 1♂ flying upstream along the river in front of camp at 1300 hrs - Year's first. 29 May a flock (!) of 6 squatarola plus 1♂ individual, making the black-bellied plaver again a common Merle giver therebund. One displaying by the airstrip at VDB30. Others distributed along TS + 2 by the end of TII, 30 May compared to P. dominica, squatarola is both infrequent + quiet. 31 May ♂ displaying consistently by W end of runway. I happened to be there at 0830 when a solitary ♀ flew overhead. The ♂ (unattracted) mates) did not give chase. Instead it repeated a single, plaintive display call into a single minor key whistle (whereew.... whereew .... whereew) about 1/2 seconds as the ♀ flew by. 17 June see journal
