SP Myers 1974 Journal 63 29 March contl Punta Rago, 15 Km N of San Clemente del Tuyu by road, Ptdo de Gual Lavalle, Pcia de Bs. Aires, Argentina Plovers, Sandpalling, WR's, and Arenaria interpres. The Knob were foraging directly out from the road on the beach (there were 8). We're [illegible] area in the lagoon described 3188 at the end of our exploration lying along the windward shore. Until 1930 I detected little change in the general picture, except that 6 falllandians were by then roosting in the roost. We had been walking up and down the beach, certainly not contributing to the birds' bliss - nor were the activities of several other humans. Probably as a result, some of the birds, particularly the Knobs, rightcatchers, plovers - moved out just passed the lagoon, beyond the forces of human activity. Knobs by that time numbered 14, and I was visiting with a flock of 100+ terns. Between By 1500 the roosting flock had swelled to 90-60 birds, composed of more than 50% falllandians, most if the rest WR, one Arenaria, and one knob. We sat down by the beach in site of the roost, watched the birds enter. Some flew directly in, from points beyond view in other directions, along the shore. However WR's often stopped to forage in the beach in front, and after a variable interval they flew scurried up the beach. The terrain approached this way, as did a few falllandians. When I finally collected them were 3 sandpalling down on the beach in front as well. Typically the approach pattern, if it involved a stop to forage, also entailed a brief preening bout immediately prior to going to roost. The foraging site was a 10 m wide gently inclined sand beach which for over 20 min during the rising tide received intermittent shallow baths as digger waves began to invade the shore. And inland beyond this flat was a pool, less than 2 m wide, 10 m long, where several birds had foraged before the wave began to reach the gentle slope. I collected 3 WR (125-129). March 31 April Tower Llanos, Estancia Medland, 35 Km S of Juancho by road, Ptdo de Naderangos, Pcia de Bs. Aires, Argentina Rained 30 cm last night Organized blind in Tower Llanos swamp from 1615 to 2015. I placed the blind within the swamp over month ago, and have used it sporadically for photography. I moved the blind to its present position 3/26 because that afternoon I had observed numerous Mycophylla in the tiles in that vicinity. The blind was ~9 m across away from the edge of a tile strip running between higher land and open water. Dawn across the open water, on a stretch of semi-dried black mud. The water at the base of the tiles appeared to be less than 2" deep. While waiting in the blind for the swamp to recover from my ride intrusion, I
