If you're visiting Trinidad or Tobago and like to know what the birds are that are flitting in front of you, this is a useful guide. Most of the commonly seen birds are there. There are birds on Tobago that are not seen in Trinidad and vice-versa. Unless you are reasonably into birds, this is a good little guide. Personally I bought this and the Birds of Trinidad and Tobago Helm Guide[Martin Kenefick and others]. I found both useful, the real photos by Roger Neckles in the Richard Ffrench book being an additional help. If you are in this area, I do recommend going to the Asa Wright centre and Caroni Swamp, both in Trinidad. The first has brilliantly coloured birds and in the swamp you can see all the vivid scarlet ibis fly in to roost by late afternoon, a magnificent spectacle for anyone who enjoys wildlife. I enjoy bird photography and both books proved very useful. It is worth paying for a local guide on both islands as they'll point out birds you'll otherwise not notice.
