of Worembur and continued today, a low heavy cloud cover with occasional drizzle.
Accumulated 5mm during the morning. Grid totals: C. fuscicollis 12; C. bairdi 3;
Limosa haemoptica 2; Tringa flavipes 1; Vanellus chilensis 1; Pluvialis dominica 5; Chenidius
falklandicus 1; Himantopus h.1, Ardeola ralloides 2; Anser gryphus 6. The strong S wind,
which has picked up since yesterday created arroyo conditions very similar to those
created 4 November by a similar but even stronger wind. Thus three were flocks of WR
at 14.13 in the Arroyo, between subunits 7-8, and above Hullican grid (15.25)
actually as there were 4 November. After running the grid I collected two non-
territorial Tringa tots (172-173) from (13.23) and 2 territorial WR from (15.25). See repeat
acoustics.

17 November - left camp in pre-dawn hours with the intent of beginning calculation for another fuscicollis
% territorial bird calculation. However as the light increased the weather turned ominous, dark
clouds cumulonimbus piled to the SW, from where the wind came. Dawn itself was one of the red-
dot I have ever seen here. Cooling morning temperatures ran 11-13°C. So upon reaching
Tower Clancy I decided to take microhabitat data and to collect a territorial fuscicollis
before being forced in by the rain. But the weather developed contrary to my expecta-
tions. By 0830, after a period of 25 minutes during which it rained 5mm at the farm
hours, the bulk of the storm had rolled over, leaving a dark mass still to the
W NW, but one which contained NE only without dumping upon me. Accordingly,
I pulled the canopy a previously chosen site and begin the % territorial WR calculation process.
The unit of habitat chosen lies in a fairly typical stretch of Arroyo where I have seen
numbers of fuscicollis foraging in both space-specific and n.s.a. fashion. There is
5 ft in ~10m wide at the narrowspot of hug, with a broad overpass on the N edge
where a spit of water extends several meters in the upstream direction away from
the main body, leaving a narrow cape of saturated mud running down the center
of the grid in that portion. I took microdata there early a, the morning (face
