JPMyers 1973 Journal by road 928 Km NW of Buenos Aires on Pcia Route #157 Nef Tentera Totoralejos, Pcia de Cordoba, Argentina Oct 3 We were driving north from Cordoba, Pcia de Cordoba, towards Tucuman via Route 157, having left Cordoba ~7AM. The road is flat for the 1st 50km and then begins rolling, especially after cutting away from the road National Route 49 toward Santiago del Estero. The area is very dry, with many cactus - largely prickly pear and later an organ-type. About Km 900 (Cumberland from BA) we passed the first standing water. There had been a series of brackish water-holdings which were dry. The water was in one such thing, with cattle + people around it. No storebirds. At Km 928 we passed a series of small roadside puddles, more than 15' across (i.e. water more than that width), but extending for perhaps 500' along the road. 18 Baird's sandpipers were spread along this length. I collected 2. Soon after the ponds were salt, and surrounded by salt borders of mud ~5' wide on both decades. The dry mud went to the road on one side and up the axle of the right-of-way to the other. Vegetation beyond was low xeric scrub. Less than 20km beyond the collection site we came onto a great salt flat, which we had been bordering for at least 50 km. At one pt. I had seen, from a vantage pt., well out it, then second to be patches of standing water. But it could have been mirage. No other storebirds were seen the entire day. We spent the night between Frias and Santiago del Estero (where we were going for carpins) in a small range of hills.
