Natural history of Trinidad and Tobago hummingbirds to the primitive cave-dwelling oilbird (that uses sonar to fly in the dark) to the spectacularly beautiful scarlet ibis. The islands are within a few miles of Venezuela, and the species are therefore typical of tropical South America. However, the variety (although quite exceptional for such a small geographic area) is somewhat impoverished compared to the mainland, as would be expected with small islands. The resident breeding birds are augmented in the northern winter by migrants from North America. Tobago has only about half the number of bird species of Trinidad, but about 22 birds have been reported only
History of Trinidad and Tobago of Paria via the Serpent's Mouth and the Caribbean Sea via Dragon's Mouth. Trinidad is reported to have been densely populated at the beginning of the colonial period. Although in 1510 Trinidad was said to have the only "peaceful Indians" along the whole South American coast, demand for slaves to supply the pearl-fisheries in nearby Isla Margarita led to them being declared "Caribs" (and thus, fair game for slavers) in 1511. As a consequence of this, Trinidad and Tobago became the focus of Spanish slaving raids, primarily to supply Margarita's pearl fisheries. In 1530 Antonio Sedeño was appointed governor. Granted
