JPMayers 1977 Tryngite subvuficollis Produce Bay, N. Slope, Alaska 23 June (Contd) 0130 walking around the "Barrow analog" (see journal) found 2♂ Tryngites displaying - a good helicopter flight with legs hanging loose in flight (yes that's in flight). A bit of flutter-jumping. No♀ 24 June Tran 2 - ♂ Tryngite displaying on a pingo! first saw flutter jumping, then curing flash. It was near Hucutt but moved off quickly. 1100 passing near same pingo saw 2♂♂ in border display: they flew up together rising ~ 20m above ground vertically as diagrammed, fluttered way up (high), then returned down warior on same trajectory. 25 June (uffis all over transects, beginning w/ #8+9 in morning. ♂♂ conspicuous at several hundred meters in border display flight - no their spinner change up flew 2 beside fluttering together at 50 m+ off the ground. Buffy Pingo (see map 26 June journal) - (uffis coming out the gump shumps. began at 1500 when I picked on up on T11, foraging at the top of the creek basin. then as I continued along T11 I could see ♂♂ over Buffy Pingo in border display. Then on T10 I recorded another. Finally, returning toward the pond 6 ♂♂ began hopping + jumping all around, generally chasing, calling - tic-tic-tic in the air as they came down from the border flight w/ outstretched wings, head jerking (a flying Parabola??) Also giving flight chunk. Stumbled over next on side of pingo within display area - 4♀ w/ a delicate + very tolerant ♂. Nut in upland tundra, some Eriophorum vaginatum present (but not a good stand) of E. tussock tundra. A bit more moist than quickly that. Salix reticulata lining next. Then at 1850 along T5 I encountered 3 displaying ♂. I was virtually beneath a no pair of ♂ in vertical border flight. heard nothing but as they flew out of it one of them went into a very pronounced shape + dove back to the ground, something reminiscent (strongly) of a Calidris ruficollis glide flight (see 1976 notes) 29 July been been in Prochor since 18 July w/o seeing Tryngite (see daily list). Then today in stabilised dune by East Dock saw one adult ♂ w/ 8 Pluvialis dominica
