J.P. Myers 1973 Journal 4 Km 275 W of Viatayes by road, Dept Pres Hayes, Paraguay July 27 Again a cold morning - ~5°C. Clear, only a thin line of clouds eastward extending along horizon. I walked out to the same area as July 26 to photograph but met with little success. After lunch I went out at 1:30 to collect. Shot 1 Vermillion-crowned flycatcher (08) along the edge of the swamp. From the house went SE to Sibainour along telephone wire until of last swamp. The wire extends through a [illegible] swamp until it hits the swamp. The moist is a low (15-20') scrub of [illegible] diversity with only a few species of tree, dominated by what Phil tells me is a Prosopis (legume). The trees are in general not close together - 2 ft (rarely) up to 20 ft with the crowns touching. Ground cover is a wild pineapple or nothing. Often the ground beneath the trees is bare. This may result from grazing (cattle), which we learned was over here several years ago and continues on a lighter scale now. What % of the land that is not moist is palm swamp - stands of palm, trees fairly dripped with mud, standing clear water, or standing water with a solid cover of some plant (identity unknown) between them. The presence of cattle is very clear, as it is difficult to find a stretch of mud which is not densely marked with cattle hoof prints. Prints of other animals - small cats, foxes, sheep, deer, raccoon, bird, are also abundant. In the palm swamp the most easily detected animals (apart from cattle) are Vermillion-crowned flycatchers, jacanés, [illegible] cardinals, southern screamers, limpkin, plump-tailed chachalaca, monk parakeets. The afternoon along the south side of Saido swamp I watched a small fox for a few minutes moving along between me and a flock of (8-10) limpkins. While sitting in the same spot just after the fox left a
