Polysticta stelleri
4 July Barrow, Alaska These sew were in loosely associated
pairs except 24% in S Meadows Lake; they were seen
in the VOTH area, VOTH slough and the area around
Meadows Lakes.
5 July Only one pair seen in Central Marsh; they are scattered
in the VOTH area. In the evening a $ was seen
dipping for food in a pool about 6-8" deep.
6 July A pair in a small pool at the north interest may be in-
dicative of the progress of the season. The $ was almost 30
feet from the % when I approached and flushed, landing
close to the %, which began chasing the % away. The %
occasionally tried to retaliate but was always beaten
back by the %. The fight consisted of irregular alternat-
ion of "head ups", a change in which the head
was thrown down and forward and the wing was
slightly opened

and a bathing motion in which the % was thrown over
the bird's back with a circular motion of the 1/4 opened
wings while the attacking bird moved towards the other.
They were silent. 2 other pairs were seen along
Holmes's Heron and one in Central Marsh; of each
the member of its pair were not closely associated.
7 July A pair closely associating in pools near AACs and
2 $ in the VOTH area.
8 July None of those seen today were in pairs, but rather as widely
dispersed individuals. %'s not noted in VOTH area.
