Bond doesn't have the birds of Trinidad or Tabago in it, except for a few Caribbean species which make it to those islands. They are faunistically part of South America, despite being *culturally* Caribbean. Best bets are the two books mentioned earlier (Birds of T&T, Birds of Venezuela). Bill Murphy's book on Finding Birds in T&T is invaluable if you were on your own, would still be helpful on a tour in order to prep you for what you may see at various spots. Have a great trip...
