The day has been clear (no clouds), with little wind (a striking change) and warm temperatures (48° at dawn, into 70's by noon). 10 km S of the canal #5 junction we found a herd of rhea (9) around a nest (see sp. account) with 4 eggs; the eggs were in the process of being laid. 18 km S of Canal 5 a field w/ 100+ Golden plovers + sheep, ocamurs, burrowing owls, terns, churangos but no evident buff-breasted sandpipers.

At Mar Chiquita we went All along the road to the cast hue dumps can be seen, and for Hui (after part of the trip a large body of water (Laguna Ular Chiquita) is very evident.
