Further mention is made of the aguila (_Trasætus harpyia_), camaleon (_Falco sparverius_), carga-hueso (_Polyborus cheriway_), the rey de zopilote (_Gyparchus papa_), the zopilote (_Catharista atrata_) and the zonchiche (_Cathartes aura_). To these may be added the tortolita (_Columbigallina passerina_), the pavon (_Crax globicera_), the pava (_Penelope cristata_), pava negra (_Chamæpetes unicolor_), the codorniz (_Ortyx leylaudi_) and chirraxua (_Denitortyx leucophrys_); still further, the martin peña (_Ardea virescens_) and other garza (_Tigrisoma cabanisi_, _Nycticorax americanus_, _Gallina aquatica_, _Eurypyga major_), zarzetas (_Numenius_ and _Totanus_); also the pijijes (_Totanus flavipes_ and _Charadrius vociferus_), the patillo (_Colymbus dominicus_), the piche (_Dendrocigna autumnalis_), pelicanos and alcatraz (_Pelecanus_), etc. We have further to mention the great turtles from both oceans, the (_Nacar de perlas_) or pearl shells from Golfos Dulce and Nicoya, the oysters from Puntarenas, the purple snail (_Murex_), also sponges, corals, etc. V. THE ABORIGINAL INHABITANTS. Colonel George Earl Church says in regard to the Indians: “There are many indications that Costa Rica was once the debatable ground between the powerful Mexican invader and the warlike Caribs of northern South America.” “The Caribs were a tall, muscular, copper colored race who, when the New World was discovered, occupied the coast from the mouth of the River Orinoco to that of the River Amazon, and stretched inland over all the half-drowned districts and far up the valley of the Orinoco. Their nomadic spirit led them to the conquest of many of the Windward Islands, and, I am disposed to believe, urged them to invade all the countries bordering the Caribbean Sea and Gulf of Mexico having estuaries and rivers which could be penetrated by their war canoes. These carried from twenty-five to one hundred men each and were of sufficient size to make long voyages.” Along all the Caribbean coast districts of Yucatan, Honduras, Nicaragua, Costa Rica and Chiriqui, and throughout the province of Panamá, the Carib has left traces of his presence. It is evident that an offshoot of the highland Mexican race pressed south and east from Chiapas, Mexico, into and through the long strip of the Pacific coast occupied by the Chorotegas or Mangues, followed the Pacific slope of the Cordilleras and the narrow space between Lake Nicaragua and the Ocean, penetrated into northwestern Costa Rica, settled and helped the Mangues to develop a considerable civilization in the district of Guanacaste and Nicoya, and in part subdued all the volcanic region lying north and west of the valley of the River Reventazon. It is notable that inhabitants of volcanic countries crowd around the slopes of its volcanoes, due probably to the fertilizing quality of the ejected ash.
