JP Myers 1973 Micropalama himantopus 300 km W of Viale Hayes at lagoon by retire, Dept Pres. Hayes, Paraguay Aug 30 stilt sand piper flew in w/a group of greater yellowlegs at 6:55 while I was watching a melanotus. [illegible] slightly smaller than GY's, legs greenish, bill slightly larger, tail clear white. Kept in group of yellowlegs while feeding Mouth of Canal 7 into laguna Mar Chiquita, 22 km W of Mar Chiquita by road, Pucia de Buenos Aires, Argentina 17 October I finally got a good enough look at the odd birds today to be able to ID them as Stilt Spiders. 10 of them foraging in very close groups 11 November Two flocks of Stilts in pond just W of mouth of Canal 7. ~20 all told. Again, the tightness of their flocking so impressive. And the crazy erratic flight! Farmhouse puddle, Estancia Medland, 35 km S of Franco by road, Pucia de Buenos Aires, Argentina 24 November 13 Stilts foraging in the puddle at the far Send from the road. Their heads are always down. They are very close to one another. No aggression with nearby Peafowl. 16 December Molino Grid (#3), 500 m N of farmhouse, Estancia Medland, Pucia de B.A., Argentina Not on the grid, but in the major swamp 100 m W (and past a row of bunch grass) I spotted 3 Micropalama with a flock of 6-L Vlugs. They caught my eye first because of their tight foraging group and feeding style, and only later did I recognize them as Stilt Spiders. The 3 birds were almost facing each other in a tight triangle, less than 3 ft apart from one another. Grid 9 (Farmhouse Puddle), Estancia Medland, Pucia de B.A., Argentina 20 December Took feeding hood position data from one of two Mice's foraging close to blind on grid; sampled position (down or up) every 5 sec: Up, Down, Down, Down, Down, Down, Down, Up, Down, Down, Down, Up, Down, Up, Down, Down, Down, Down, Down, Down, Down, Down, Down, Down, Down, 19 Down; 4 Up 0815 watching feeding technique again: the bill is almost immersed in the water between the base of the exposed salmon and the front end of fly eggs. They do go so far as to stick the egg into the water
