　　From Bahia Blanca Darwin traveled north across the Argentine pampas accompanied by gauchos who hunted with bolas and lazos . Along the way he met the Argentine dictator, Juan Manuel Rosas, who was engaged in a war of extermination against the Native Americans of the pampas. He saw flocks of rheas, a form of ostrich, which were flightless but could outrun most horses. Darwin found the remains of an unknown species of rhea that he sent back to England and which was named after him?I rhea darwinii.

　　After reaching Buenos Aires and resting a few days at the home of an English merchant, Darwin traveled up the Parana River to the port city of Santa Fe, where he saw some more fossils. He then made a trip from Mercedes to Montevideo in Uruguay, where he met up with the Beagle on December 6, 1833. In March 1834, after having visited the Falkland Islands once again, the Beagle went back to Tierra del Fuego where they met up with one of the returned Fuegians. In April they sailed up the coast of Patagonia, putting into the mouth of the Santa Cruz River to carry out some repairs.

　　On April 18, 1834 Fitzroy and Darwin with 23 men and three whaleboats set off on a three-week journey of exploration up the Santa Cruz River. They saw continual signs of Native Americans but never met up with any in the cold desert region of southern Patagonia. They traveled to the foothills of the Andes and came within a few miles of the river s source at Lago Argentino without realizing it. Along the way, Darwin shot a condor that had a wing span of eight feet. To Darwin s disappointment they were forced to turn back because of low supplies. The others wished not to, but Darwin remained cheerful: Almost every one is discontented with this expedition, much hard work, and much time lost and scarcely anything seen or gained ... To me the cruize has been most satisfactory, from affording so excellent a section of the great tertiary formations of Patagonia.
