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.

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. Most of
trail was through monte - Prosopis semil; we were looking for deer and/or
peccary beat. Saw one deer on the way there, but it stayed too far away for
a shot. Did get two of the many chachalacas seen for heard. We did
very little bird watching. Of interest however was a mixed flock of oriole -
spaullet, golden-winged cacique troopial that we encountered along the
trail on the edge of the monte - palm swamp ecotone. The spaullets
were both on the ground and in the base of the palm leaves perhaps 15' up.
The other two species were in the palm center and leaves, with the
