53 Journal JPMayers 1974 21 March. (contd) At 11 Pond, Estancia Medeland, 35 km S of Tuancho by road, Pte de Madariaga, Pcia de Buenos Aires, Argentina Threatening for several hours (and indeed raining palpably too beyond the Farmhouse toward the coast) [illegible] to the wind and moved off. After southern lapwing scared off all but 2 of the Redshank, I called one (11?), surveyed the rest of the pond, and returned to Arroyo Chico. In the rest of the pond were 7 more Redshanks, a few lesser yellowlegs, southern lapwings, a small flock of Spotted teal, 13 Wood storks, numerous pale-browed gulls (foraging on the convergent vegetation) and a new arrival (it would appear) to this habitat, a Cinclosoma spp. perhaps flavirostris (but I will call it). Its appearance has been quite dramatic—it is now blue in maize where before there were none. Arroyo Chico, Estancia Medeland, Pte de Madariaga, Pcia de Buenos Aires, Argentina. 12:30 began yet another linear grid reading. Clouds were 10%, with a strong N.W. wind. Temp = 22°. Coward skua dominated the grid reading, as they usually do during mid-day sample. Several subjects suffer more extensively from these plans, particularly, 1, 2, 3, 4, 9, and 10. Grid totals: WR 3,5(8); Charadrius fulicarius 6,5(11); Hudsonian godwit 1,0(1); (maker) Yellow legs 0,1(1); Neotropic Cormorant 1,0(1); Spotted teal 5,4(9); Shoveler 0,3(3); Brown-headed Gull 0,1(1); Rufous-backed gull 0,0(1); Cinnamomops pipit 0,2(2). Oof! what a measurable quantity of war, surprised even by Spotted teal. However this was to have been expected, given the paucity of birds present in the dawn reading, and the fact that usually flocking birds coalesce during mid-day hours, thus reducing even further the totals. 50 WR sp. accent. Mouth of Canal Fuerte Laguna Mar Chiquita, 23 Km N.W. (Mar Chiquita by road), Pte de Mar Chiquita, Pcia de Buenos Aires, Argentina 19:30 arrived at Canal. I was prevented from an extensive exploration because of 2nd degree bruise on my left foot (which have hampered my movements for 4 days now) but I was able to skirt along the Wedge of the lagoon for ~750 meters to N from the mouth of the canal. What a sight! My last visit here, 8 March, was tempered by a thick fog which prevented any overhead. Today the sky was only 20% overcast, with a very strong N.W. wind blowing down the length of Laguna Mar Chiquita. The wind appeared to have pushed considerable water to the South, making this area much shallower— indeed where the several hundred WR had been foraging 8 March there were none today
