JP Myers 1943 Journal 15 At northern end of lagoon, near Retiro on Eaton's Ranch, 1 km of Trans Chaco Highway, 300 Km W of Villa Hayes, Dept Pro Hayes, Paraguay Aug 30 See map of location, Aug 29. Bob and I left camp at 6:30 9m and walked to northern end of lagoon. 100% overcast, slight S wind, temp = 58°F. Shorebird there again. This time I came with scope (but again w/o Peterson.) When we left at 6:25 there were 5 SB flying along east side of lagoon 6:35 at N end 6 Yleap 6 smaller sp. 6:45 6 more small sandpipers came in some of the little SBs are definitely White-rumped (C. fusicollis) too. 2 on beach in front at 6:45. Somewhat I found a Pectoral feeding with 3 Yleap. on Nw end. One more C.fusici. appeared just when the others left. At 7:25 still sandpiper (Micropluma himantopus) came in w/ Yleap. We tried to shoot some of the birds but were too far w/ 410+ dust shot. Went back to camp at 7:30 after having chased everything away. Two adult teal + 11 ducklings in lagoon. Trail to Rio Berce from Retiro on Eaton's Ranch, 1 km W of Trans Chaco Highway, 300 Km W of Villa Hayes, Dept Pro Hayes, Paraguay At 9:00 Phil, Lora, Lou, Filipa-i + I walked to river from camp. River is such only infrequently, now being a series of interconnected salt pools, bordered by cracked wald, mud, salicornyx (or the local substitute) and running through very thick Prosopis aculeata Prosopis aculeata. A herd of 25-30 collared peccaries crossed the river just as we arrived. Slight wind, overcast. After chasing the peccaries unsuccessfully we headed S along river. Soon saw a solitary sandpiper (T. solitaria). chased it for 1/2 mile but could not collect. No other sandpipers seen in river. 1 Kiskadee foraging along banks, 2 tree ducks, incredible number of mammal tracks: mata lion, tapir, capybara, crab-eating racoon, small cat, fox, deer, paca, gypson. Many were fresh. The water contains a great deal of swimming invertebrate life, and I am surprised that there were no other bird species using it. We walked back along the same route and in coming. Temperature getting up, cloud cover still complete, wind also rising from south.
