JPMyer 1973 8 July 28 cntd 275 Km W of Via Hayes by road, Dept. Pres. Hayes, Paraguay. Troupial definitely more peripheral than the golden-winged. Although I remember no other species being present within that particular flock, these could have been, as we tarried not; however at a second flock with similar species seen a little later there were definitely others present although I did not specifically note any. We headed WSE until reaching a large clearing running NW-SE (90° to our line of travel) and then took it to the NW. The original clearing was actually very dense but low (10-15') brush in a damp area. To the NW it opened into a very large (0.5 km²) meadow, bordered by palm swamp, forest, and swamp caused by the dam. There was also open water at the far NW side of the meadow. Upshot were up to 10 maguaris troop, an unknown number of southern screamer, plumbeous (Cuff-necked) ibis, zero-two, uncountable numbers of vermillion-crested flycatchers and conclusively, some tistade flycatchers and others. Also overhead flew a large flight - perhaps 45 - muscovy duck. We walked along the SW side of the meadow and then headed back to the cabins upon reaching the dam. The forest on this side of the meadow was dense, high (30-40') and green; not the typical monte. Pteropus pigeon roosts in the higher trees of the forest (and in all of the surrounding monte). We shot several of these to augment the charata (chacluba) as well as a few white-tipped doves. Their breasts were delicious, although minuscule. # The afternoon of the 28th, we went to a nearby retiro for the Rincon Charrova ranch (Retiro Loma Jhovy) for Phil's bat work. At the gate house to the main ranch (Km 275) we were offered a red-legged sercima for sale, and told that it had been caught in the nearby monte.
