Journal Atkasook, Meade River, N. Slope Borough, Alaska 5 June (cont'd) Lagopus lagopus abundant 31 May. 8♂ mated to 1♀. 9♀ more extensively. Some ♂♂ fighting. ♂ displays constantly (flying up + sailing down w/ tail spread, calling). By 3 June convinced that 9♀ have nests but unable to locate any. ♂ stays very close to 9♀, acts as decoy - in most habitats. Common Lagopus mutus. evident 31 May but uncommon compared to L. lagopus restricts to sand dunes, drier lower cliffs + ridges. ♂ not begun molt. 9♀ will along ♂ displaying 31 May - 5 June. common Ploceidin dominica displaying actively 31 May. much chasing. paired by that date. underused habitat use but seems prefers higher ground, I think. Heavy overlap w/ P. squavola (see below). By 5 June pairs behaving as if nest. common P. squavola - intense display activity 31 May - 5 June. much chasing, butterfly flight. Strong ant distraction display 5 June. (rowing motion by ♂). Defensively prefers higher ridges + bluffs but also seen in low areas (maybe only those w/ ridges nearby?). common Arctaria interpres - displaying + chasing actively by 31 May near camp and a few other sites. But not seen 5 June, uncommon 4 June. they may have moved on. RARE (<10/day) 6 June 1 seen in 4th probable ant distraction on loopy ridge (next to chicken function) Calidris melanotus - ♂ shooting when I stepped off plane 31 May. see sparent. 9♀ giving bug-off display to ♂ by 3 June. But 9♂ flocks flying by through evening of 9 June. Next found evening 4 June. Widespread in habitat but more concentrated in low areas. Carex strings, extensive LCP's. ♂♂ also on ridges. ABUNDANT C. mauri - displaying actively evening of 31 May. Continuing throughout through 5 June. some aggressive interactions w/ C. pusilla. ♂ neat cup displays, intensive choice. habitat largely restricted to wet tundra + nearby ridge particularly near lakes, pools and lakes. ♂♂ tool about over considerable distances, but display focus well defined (i.e. patchy). I cannot discern habitat difference from C. pusilla save that many pusilla are also in drier ridges than mauri. common
