JPHugers 1973 Journal 7 July 27 cont'd 275 Km W of Via Hayes, by road, Dept Pres Hayes Paraguay is remarkable. What might this have to do with calitridines? especially with insectivorous calitridine going (wee they to feed here). [It should be observed that because of low temperatures (down to 4°C at night, up to 30°C in day) insect abundance is (according to Phil) much lower now than usual, there are few mosquitoes, in contrast to the normal situation. No clouds till afternoon, then only small puffy cumulus, cleared at night. Phil and I went out night-lighting with head lamps - spotted two foxes, two anteaters (same species as I had seen earlier in the day). We walked along the fence readily east from the building complex, thereafter about 1 Km followed another fence north and W.W. for a short (less than ½ km) distance. 2 species of capimuliform, neither collected nor identified. One might hawk-like with wing spots and white on tail; the other also gregarious, the other solitary and saw the conspicuous white marking. July 28 Phil and I walked (beginning at 6:30 - clear, 5°C) toward NE to dawn (?) then perhaps one or two Km beyond, continuing to NE.
