this summary brings out several trends. First, there are obviously non-breeding flocks of several spp.
moving through, including not only C. melanotos and Ph. fulicarius, but also alpina, mauri,
and pusilla. These latter three species may be moving between the Uota Creek mudflat and
the grids; several days ago they definitely were, but recently we haven't seen appreciable
quantities on the mud. If they are, we have to question the importance of the precise
positioning of the grid w/reference to achieved densities. As I noted before, C. melanotos are
still displaying - boots, chases, and groove displays. Some ♀♀ have chicks, but we appear to have
picked up a significant number of birds passing through in flocks.
Evening - during the evening Planners and I went to the area between POW-MAIN and
a coast guard radio antenna complex, defined on the NW by Lankpok Lake, and the SE by Central
Marsa Sough. Our intent was twofold - first to photograph an Asio flammeus on a nest which had
previously proven to be very cooperative, as well as an incredibly tolerant Pluvialis d., and then to
to survey the region as a possible site upon which to place a grid. From conditions there today,
it would appear to be a good location - C. melanotos brooding suggest that pre-natal activity was
adequate, other species were also present in force - dunlin, semipalmated plover, golden plover, and
phalarope. I see two drawbacks - (1) It is somewhat disturbed by vehicle tracks, with several
lines running through, and (2) it is close to the ocean. Thus if our censuses, as hinted at
above, are affected already by piling up along the coastal zone then with this area we will
be even more prone to such density inflation.
