The Caribbean island of Puerto Rico is the easternmost of the Greater Antilles. It is a dependency of the USA, uses the $USD, and is reached by many daily flights from the US mainland and some from other West Indian islands. There are some exciting endemic birds, many common and fairly to see and photograph, including two hummingbirds, the Green Mango and Puerto Rican Emerald, Puerto Rican Tody and Puerto Rican Woodpecker, and others which are a little harder such as Puerto Rican Parrot and Screech-Owl and Elfin Warbler. Several good reserves lie within easy reach of the capital San Juan, such as Laguna Tortuguero, a coastal area of forests and mangroves, about an hour to the west. There are no large wild mammals on the island, but plenty of colourful butterflies and flowers.
Before joining any wildlife watching or birding tour, wherever in the world, try to establish if the travel company you are considering booking with operates in an environmentally friendly, responsible manner.
