J P Myers 1974 Journal Estancia Medland 35 Kms of Juancho by road, Paso de Madariaga, Provincia de Buenos Aires, Argentina 18 February (Cont'd) any movements in the car. I continued along the Arroyo to the N., until reaching the next fence. No water banded WR, although ~20 WR total, as well as numerous Chalks. At the fence I cut E., following it to a gate, through which passed, and then headed NE across the fields. The fields here are a higher viny/graminiv Tower Llanos-very little looks like prairie buffy habitat. Crossed across 1 field of rhea with 2 adult ♂ and 43 chicks of 2 age classes (roughly 50-58). The chicks were between 1/2 & 3/4 adult size. Another group ~10 birds which, one obvious chick 3/4 age, the other perhaps less than adult. Followed the field in this direction 7.3 Km, until ♀' it ended in a long thin lagoon-swamp. A few Pectorals (25), several WR (6) and several LYT, as well as a flock of Brown-headed gulls were seen in the area. By heading W. N. I was unable to cut around the end of the swamp to go E. again, [illegible] gate in the fence just beyond. Much of the land area which I was passing had obviously recently emerged from surface water. Vegetation was a 2' high, duff-grass which made passage in the car difficult. Continuing W. N. I reached the Bran contained to thicker, and patches of premier material (believing that the land continued to get wetter). It soon became impossible to go on, so went W. at the swamp to cut S., going through 2 gates. The second gate carried me into a region continuous (i.e. not separated by fence) with Tower Llanos, although further E. than I had been because of an extensive swampy area between the Claro & the area I was moving. The area appeared very similar in vegetation to Tower Llanos- short grass, less than 2" high, occasional thistle. Classic buffy-golden habitat. And I found a few -1 buffy+golden. Although from the car it was impossible to see open H.O., I saw a Troupian's tern diving over the swamp-lagoon, so I got out & tried even to investigate. A considerable body of open H.O., strikingly intermittently in N.-S. direction, several hundred snakes, basking by shallow river tub areas, ~100 m across at widest. Some of it looks very shallow, but the presence of (Tocororo + B-Wooded Swans), Ragg-billed Blackbirds, & Great Egret indicated that deeper water is also present. Approaching from the E., a 50 m strip of turf-grass vegetation still submerged in water. Within this strip, particularly nearer the main body of water, I found 6 Painted Snipes. They allowed me to approach closer than ever before, although I have yet to see one before it flying. One flock of ~50 WR flying along the E. side of the lagoon. I then returned to the Farmhouse- it was necessary to extract any rocks left through the last gate because advance in either N.-W. or E. direction from the E. side of this Swamp-Lagoon was cut off by tall grass and/or water. No buffalo or golden-wing on Tower Llanos.
