JP Myers 1973 Journal 39 Rucial Route #304 between Acheral and Antiguo Quilmes, Pcia de Tucuman, Argentina 5 October contd field by the road. ~50 yds f to the S from the road the river formed a steep embankment, with a broad open field on the opposite side. On the grass across the river were several pairs of Southern Lapwing, as well as at least one more pair of Andean. The river at this point had much sand and open banks along it. At the WNE end of the valley, beyond Tafi del Valle, the road becomes quite steep rising to 9900' in 23 Km. Beyond the site described above I saw no Southern Lapwing, but many Andean. Rufous collared sparrows were common in the bunch grass and along gullies. There were an incalculable number of thrushes - at least 2 species, one being definitely Ceranotus melanoleucus, the other probably B. polymorpha. These birds soared extensively, and also used the extensive outcroppings of rock for perches. Chiguanco Thrushes (Turdus chiguanco) were common as well. At least 2 furnariids (one Cinclodes - almost certainly atacamensis, seen in gullies and ravines, and I found one nesting on the bridge spar over the river at the south end of the above valley (6000') and one which I did not ID but do have a 35 mm photo of several hovering owls, including a mating pair (their pellets had much mammal fur in ALL them) at 8900'. The only Carencho I saw up the river was at 7000'. Spanow hawks (modified by Andean Lapwings). Above Tafi del Valle (6000') the only trees were by houses, of which there were one or two every few Km. Vegetation was otherwise some sort of bunch grass, being grazed by horses, sheep, and llama, and guinea pig
