The islands of Tobago and Trinidad have some of the best birdwatching in the Caribbean, with over 468 recorded species of birds between them. Around 250 species of birds actually breed on the islands. There are not many places in the world where so many species of birds can be seen in such a concentrated area, many of them unique, very rare, or of particular interest. Trinidad is well known as a birdwatchers paradise. But Tobago also has about 220 species of birds. Some of the birds of Tobago are not regularly seen in Trinidad. Tobago has a number of sub-species of birds that are not found anywhere else in the world.
Both islands were once part of the continent of South America. Because the islands are so close the South America, many species migrate north and use the islands as wintering grounds. Also, many birds from the Caribbean, and even North American migrate through Trinidad and Tobago on their way south. So birders may see birds from North America, South America, The Caribbean, and of course the islands themselves.
Because of the variety of birds, bird watchers come for both Trinidad and Tobago birding tours. A quick search on the net reveals many companies that offer these birdwatching tours. Some of the birds you might see in Tobago are cocricos, peregrine falcons, ruby-topaz hummingbirds, white-tailed sabrewings, jacamars, blue-backed manakins, fuscous flycatcher, blue-backed manakin, venezuelan flycatcher and olivaceous woodcreeper.
