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
South African Class Experimental 6 4-8-0 South African Class Experimental 6 4-8-0 The South African Railways Class Experimental 6 4-8-0 of 1906 was a steam locomotive from the pre-Union era in the Cape of Good Hope. In 1906, the Cape Government Railways placed a single experimental 10th Class steam locomotive with a Mastodon type wheel arrangement in service on its Eastern System. In 1912, when this locomotive was assimilated into the South African Railways, it was renumbered and designated Class Experimental 6. The Cape 10th Class steam locomotive was designed by H.M. Beatty, the Locomotive Superintendent of the Cape Government Railways (CGR) from 1896 to 1910.
