S Pilligers 1974 Journal 1 June (card) Entancia Medeland 35 km S. of Juancho by road, Pte de Gral J Madariaga, Pcia de Bs Aires, Argentina *Asthenes sp. B (yellow spot) *Phacellodomus striaticollis 3 Ptinus sulphuratus 3 *Pseudocolapteryx flaviventris 1 *Tachurus rubrigaster 15 Scopophaga subcrisata 1 Hymenops perspicillata 2 Sicalis luteola Tachycineta leucorrhoa 2 Embernagra platensis Troglohydta Vagelhydta aton 2 Conostichia capensis 7 August 14 km N of Cafayate by road, Pcia de Salta, Argentina Gorge 1130 stopped at marsh at the westerly upper entrance into the Quebrada de Cafayate. highs overcast with very strong wind coming up out of the Quebrada. Temperature ~50°F. At the width of the Quebrada, Rio Conchas is a circle, shallow river which at this time of the year has largely dried, exposing large expanses of sand (salt-covered). A few narrow shallow (<12") channels remain. Along the E side is a small cienega, a marsh bordered by pampa grass and sand, never more than 8" deep, and covered with a very green grass which protrudes about 3-4" from the water surface. Small minnows and tadpoles abound. I trudged through the marsh and sand flats for an hour looking for Phoenis - there were none. Spp present: Milvago chimango, Rallus sanguinolentus, Charadrius collaris (8), Vanellus chilensis (5), Larus serranus, [illegible] anurophitha aymura, Ptinus sulphuratus, Hymenops perspicillata, Lessonia rufa, Muscisaxicola, Peitzes militaris, Phrygites gayi, Sicalis sp. Embernagra platensis. The representation of tyrannides was striking considering the time of year, all tide, + paucity of other species. 23 August (Returned to Medeland yesterday evening) 0830 drove from camp out into areas where it had worked last year. Temp 12°C at that time, with a dense haze, undeterminable cloud cover, and slight SE wind. The weather was quite unusual in my experience because of the haze - despite the low temperature it but an oppressive air to the air - the foreboding proved to be true, as by mid morning brief showers were falling, and at 1230 a violent electrical storm passed over. Today may prove to be the first day with substantial rain in some time. I am amazed by the dryness of the land - we were told so much about how incredibly wet the winters are here, and how all the swamps fill they
