JPNayers 1977 Heteroxelus biviceps Elson Lagoon, NARL, Barrow, Alaska 19 June 1700 - Bob Boekelheide found a polyneian latter this pm + led us to it. Unfortunately we don't have a complete set of collecting equipment, something to be remedied tomorrow. However all four of us got excellent looks at key characters: It is a Heteroxelus who doubt: dark size of Tringa flavipes but shorter legs (legs yellow), a straight thick bill, dark grey & back w/o flecking of Tringa, barred chest, gyeastapes, but the belly changes abruptly from barring to almost pure white. [illegible] called in flight when spooled with an [illegible] like note. Tail is noticeably lighter than back in flight, but not white. 20 June Boekelheide collected above here this pm. at [illegible] my insistence. Specimen going to U of A. museum.
