How many species of birds are there?
Natural history of Trinidad and Tobago
472 species of birds have been recorded in Trinidad and Tobago (and the list of recorded species seems be still slowly increasing from year to year). There are few places in the world where so many birds can be seen in such a small area (with probably one of the highest bird species to area ratios of any country). Many of the species are very rare or are of particular interest. They range from the many species of 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.
