There are something extensive. Occasional Spartina 'dikes' run through the middle of tube strips. 2 spp armadillo seen: molita (S,G) and peludo (P). Many nutria tracks in eastern swamps. Some possible capybara (rankhands say that they are present there.) Farmhouse to Rk 11 to 10 km N of Estancia Medeland, Ptdo de Madariaga, Pcia de Bs. Aires, Argentina 8 September 0905 left camp. temp = 8.5°C. clouds = 100%, very strong S wind which blew all night and brought brief [illegible] periods of rain. During the night a storm moved in (as Don Juan predicted because of the strong N wind of the last two days). But it has produced very little rain. It drove directly to (1,20) the short-grass fill along the Wedge of the Estancia by Rk 11. I wanted to check out the shrewbird population here, last examined 1 September, because of the recent period of N wind (which may effect the precise timing of departure and arrival of migrant shorebirds). Thus, I anticipated possible changes: decrease in S temperate breeding sp (i.e. Oryzolus, Zonibyr) and increase in N temperate (Pluvialis, Tryngite). Certainly, all but Oryzolus conformed to prediction. Tryngites finally appeared definitely, there were noticeably more Pluvialis dominica, and Zonibyrx were [illegible]. Oryzolus appeared much or less the same, although as noted elsewhere it is disappearing from other locations. See appendices.
