Patagonian bonneted bat it is not thought to be in rapid population decline. Patagonian bonneted bat The Patagonian bonneted bat ("Eumops patagonicus"), also called the Patagonian dwarf bonneted bat, is a species of free-tailed bat found in Argentina, Bolivia and Paraguay. It was described as a new species in 1924 by British zoologist Oldfield Thomas. Thomas had obtained the holotype from Argentinean-Italian scientist Roberto Dabbene, who worked in Buenos Aires at the time. Its species name ""patagonicus"" means "belonging to Patagonia." The Patagonian bonneted bat was widely considered a subspecies of the dwarf bonneted bat ("Eumops bonariensis") from approximately 1932 until the 1990s.
Patagonian Ice Sheet of more than 500,000 km³, of which about 4% remains glaciated today in two separated portions known as the Northern and Southern Patagonian Ice Fields. The ice-volume reduction contributed to a global sea-level rise of about 1.2 meters. However, during the first glacial period at the beginning of the Pleistocene ice extended to the present-day Argentine coast. With each successive glaciation it is known that the ice has stopped further and further to the west, with aridity always serving as the decisive factor halting glacier spread: it is believed that the east-west precipitation gradients during glacial periods were even steeper
