Erolia melanotus
4 June Barrow Alaska
Several birds seen today - these were on the

guess 6-7 different 8? were seen. In one
case three were seen being chased by another,
indicating that this one individual was
already settled, while the other three were just
moving in.
Another similar case was noted just east /Vath's
area. A 9 was feeding on a grassy sedge slope.
A 8? flew in landed about 2 feet away, immediately
went into its courtship posture - tail cocked,
and not spread. Wings held in normal position,
possibly slightly drooped, head held high but
bill nearly horizontal - Throat sagging
& slightly bulged. - see attached diagram.
The 8? moved in a circle around the 9 in this
posture about twice when another 8? flew
in, landed, called (could see beak move - but
wind obscured sound) & The 1st male flew off,
followed by the aggressor & a chase ensued,
The 2nd 8? displaying violently with the throat
sacs. The 9 continued to feed. After watching
the 9 for about 10 minutes, she gradually
worked her way up to the 8?, who was now
feeding. When he first saw her, she was no
more than 5' away & he immediately assumed
