JF Myers 1975 Calidris melanotos 03 Grid 2, N of Smithsonian Building, 4 km S of NARL, Pt. Barrow, Alaska 10 June (conf'd) that his natural sac was bloody !!! In fact the stain made him look like a frigatebird in display. It was obviously growing in size - i.e. the wound was fresh. He definitely was not bleeding 15 min prior. No jaegers had flown over. Landed in (6,2) region after losing ♀. Within 3 min of landing, Bloody Bill [let him be so ordained] began to fluff out feathers, to stop feeding, + to begin acting like a sick bird. "looking much less happy now." I followed him for several more minutes - it was critical to flush, although I didn't fly. At first would perk up when ♀ flew over or ♂ displayed, but quickly began ignoring, foothing (tehni) clump of grass. I could not catch it. 21:50 - began tracking 2 individuals 6/14/75-1 [see tracking grid + following data record]. Trumpet 1, [51,23 CCS], Pt. Barrow Alaska 15 June near stake #8 : 10:12 - ♂ pect east of stake on mound. Landed 30 sec ago on nearby snow, below top of mound. Struts up to position on mound w/ sac hanging low. He had been involved with other ♂ pect. ~75m E of #8. The 2 ♂♂ were strutting side by side, going parallel w/sacs jouncing like a stalker woman running. 10:30 - pectoral border near 10B stake. ♂♂ flew + displayed over ♀, following her + still hooting overhead. ♂ ? had gone from 10B stake perch mound to east, hooting low over one spot. When I got there a ♀ poked his head out of grass. Only one hoof in flight but did sweep-flutter several times, then returned to mound, stood alert facing ♀. The ♂ flew when I arrived; ♂ followed to 2 different places. 1000 m S of IBP site 1, Pt. Barrow Alaska much melanotos in here along the west side of the road. ♂♂ are accounting ♀♀ as taller fly through tundrenic: ♂ gives chase with sac hanging - draws within 2' in flight at which pt ♀ typically rises from 1-2 m above ground → 10-20 m. ♂ tries to hoot as she speeds away, somewhat comically as he alternately hoots then speeds up in order to regain closeness to ♀. Then finally, ♂ he sweeps around + returns toward territory. Sometimes however the ♂ follows ♀ far beyond border, at which pt. another ♂ joins the
