Query: Puerto Rico's Best Bird Guide

This guide is fantastic! It is well organized, easy to use, full of concise, carefully planned information, and absolutely the best bird book I've ever seen. The photos are extremely well done and very helpful. The descriptions are outstanding: accurate, thorough, and interesting. I have many bird-watchers and long time Audubon members staying here at Villas Margarita, not far from the Caribbean National Forest. They all rave about this book and the fine job Mark Oberle did on it. It is worth every penny! Buy it!
