One of the eldest geological formations in the continent, the group of mountains known as Córdoba Central Hills, uplifts in the middle of the Argentine Chaco-Pampas Great Plain. Pampa de Achala, sheltered by these hills, is a plateau crossed by streams that form deep gorges. This unique place is home to many Argentine endemic species and also the most important nesting site for Andean Condor out of the Andes. Two protected areas, Quebrada del Condorito National Park and Pampa de Achala Reserve have been established here to protect Córdoba Hills’ unique biodiversity.
Going south from Pampa de Achala and away from the humid creeks, the habitat changes into dry Chaco Woodland. This dense, thorny forest supports an amazing diversity of habitat-restricted birds, including Brushland Tinamou, Spot-winged Falconet, Chaco Puffbird, Black-bodied Woodpecker, Chaco Owl, Scimitar-billed Woodcreeper, Chaco Earthcreeper, Many-coloured Chaco-Finch and Black-and-Chestnut Warbling-Finch to name but a few.
