Distributions of threatened grassland passerines of paraguay, argentina and uruguay, with new locality records and notes on their natural history and habitat

We studied the distribution of eight species of globally threatened and two near-threatened grassland passerines from Paraguay, northeastern Argentina, and Uruguay and gathered data on their natural history and habitat requirements. The records were obtained during surveys conducted between August 2...

Fraga, R.M. Argentina Native grasslands Paraguay Threatened passerines Uruguay We studied the distribution of eight species of globally threatened and two near-threatened grassland passerines from Paraguay, northeastern Argentina, and Uruguay and gathered data on their natural history and habitat requirements. The records were obtained during surveys conducted between August 2001 and March 2004. The target species were Cock- and Strange-tailed Tyrants (Alectrurus tricolor, A. risora), Black-and-white Monjita (Xolmis dominicanus), Bearded Tachuri (Polystictus pectoralis), Sharp-tailed Tyrant (Culicivora caudacuta), Ochre-breasted Pipit (Anthus nattereri). Dark-throated Seed-eater (Sporophila ruficollis), Marsh Seedeater (S. palustris), Chestnut Seedeater (S. cinammomea), and Saffron-cowled Blackbird (Xanthopsar flavus). We confirm the previously supposed restricted and fragmented distribution of several species. Most target species occur in natural pastures with light to moderate grazing by livestock, a habitat increasingly scarce in the region. © The Neotropical Orinthological Society.
