JP Myers 1975 Phalaropus fulicarius Grid 2, Adjacent to Smithsonian building, 4 km S of NARL, Pt. Barrow, Alaska - attempted rape (6.4) - 2 ♂♂ phal. flying around a landed pair. The 2 ♂♂ started hatching 9 of pigs release ♂ then closed them off. However 1 extra ♂ remained. The pair then went through a sequence in which, facing together in H₂O, they gently bumped breasts while clucking softly ~ 7 sec duration [illegible] ♂ then wandered off toward land while ♂ remained in pond. Extra ♂ nearby. Then 1-5 min later extra ♂ flew to ♂, who squawked [illegible] as the ♂ landed on back of her. Paired ♂ broke up apparent copulation attempt before successful. Actually the ♂ squawked before the extra ♂ flew in -> a stolen copulation attempt??. "♀ appeared to be receptive" But in end both of pair flew off w/ extra ♂ following. Extra ♂ had poor - i.e. dull plumage in comparison to paired ♂. Age difference??. dn (6,2) Loral Rhy ♂ 15 June 1340 - nest w 2 eggs near (3,6) [on nest map = RPL] ♀ was in nest when food with ♂ ~ 40 cm away thereby picking up lichen + pulling it over to shoulder 16 June 4 ♂ chasing 1 ♀ in 3,6 area of grid repeatedly 21 June foraging pair in small puddle filled w/ ferning cuttings. - behavior jaceana take is that they grab dead vegetation and pull it from peck in area which they uncovered [illegible] 23 June watched + filmed series of interactions between ♂ & ♀ which ended in copulation. [illegible] appeared to be some pre-cop. behavior: ♂ squatted, raised tail + then ♂ ♀ approached. Within a 3 sec he was on top of her. 1153- another pair of phalaropes had been [illegible] in bottleneck, peeping placidly. ♂ came in, and ♂ of pair flew at him aggressively, dangling legs, chased ♀ away. Then 2 min later ♂ came in + landed on ♀ back but did not copulate. Paired ♂ went after it as well. Grid 2, 1910 - 5 ♀ chasing 1 ♂ 24 June near (9,9) of Grid 2 - 1420 - as I have been working on trapping a galeomatrus, a ♂ fulicarius / nest [illegible] has been occupied for last 30 min. by a persistent ♀ fulicarius who is changing around nest. Why does ♂ devote so much time + energy to the task of chasing ♀ off; why does ♀ persist in remaining despite intense supplicant effort by ♂? Certainly the supplicant effort will discourage new nests from establishing.
