Calidris melanotos (3).
Very active either. It is possible that the windy cold weather
was more conducive to display, but it is more likely that
the almost complete absence of females so far is the reason
for the apparent passive behavior of the males.
25 June
No birds seen on afternoon trip. This area North and N.E. of
Pitelka's Census Plot is rather low and marsh, with lots of pools
especially in the W and N. In spite of these ideal conditions there
were no Peetraals at all.
26 June
Noticed a group of five males standing in the meadow
behind AACS.
28 June
Saw a group of 37 peetraals at 22:00 in the meadow SE. of
Imikipuke lake. They were spread out over a distance of some
30 m. Some birds fed but most of them just stood facing the
wind. When a Black phase Parasitic Jaeger flew over, the whole
flock took off.
29 June.
Saw several small groups of 5,6 birds to day. One such
group fed together across the road from AACS. This morning
there was some shooting activity in Holmes Morass, and
on one occasion there, I saw a male and female fly
together. The group at AACS consisted of 3 males and 2 females.
30 June
There was a great deal of activity on Pitelka's plot this morning,
as small flocks, from 2 to 30 birds, kept flying back and forth.
They feed in the marsh and use the Bridge to rest. I only saw two
females for sure. There was no sexual chasing or any display-ing
among the males
3 July
There was only 1 Peetral (perhaps) at the N end and 3 birds of the
census plot at the S. end. This is quite inconsistent with the 30 June
