Journal 275 Km Wef Via Hayes by road, Dept. Pres. Hayes, Paraguay for hours out (and in the process missed an infuriatingly easy shot at one. On the way back I saw a tamandua - a small anteater-as it too lumbered across an open clearing by some monte. As I approached it it stood on its hind limbs, balanced with the tail, and spread its forelimbs wide. I backed off, it turned, and went up a nearby tree, As I (closer to the house I was again reminded of the infuriating situation here with respect to mockingbirds: there are two very similar "very" species both accuracy in the scrub along the edges of the monte; I believe the species are M. saturninus and M. trivirius and will collect each in order to make sure. Finally, I must comment on the remarkable density achieved here by vernal [illegible] in crowded flycatchers - they are everywhere except the center of the monte; they occur alone, in groups feeding in Jacana habitat, on the backs of horses + cattle or at their feet, with sheep, and with the large wading birds. As I have noticed previously, they are also members of some of the mixed feeding flocks. For example, in one meadow grazed by cattle (with a bull still present) - short grass with a few isolated shrubs, surrounded on one side by palm, another by monte, and 2 others by cut woods, with one small almost dried puddle at in a corner - there were over 40 v.c. flycatchers, along with up to 10 cardinals, 2 buff-backed ibis, 2 tapacings, on semillan flycatcher, one white manjita, 2 unidentified finnails (?), (with pronounced crests). And the meadow was an equilateral triangle not more than 50 yds/side, the density and diversity of insectivores - esp. tyrannids
