Ever heard of brown boobies? Neither did we, but it just so happens that this feathered friend is one of the 59 species of birds that inhabit Saba. The island's diverse terrain is the ideal breeding ground for species like frigate birds, pearly-eyed thrashers, brown noddies and a great variety of terns. Five species of pigeons and doves can also be observed in the surrounding waters not to mention the dozens of migratory birds who take a much-needed break in these lush green surroundings during their journey over the Caribbean Sea. Bring binoculars as most birds tend to blend in with the rainforest. Bond's Birds of the West Indies is the ultimate field guide to the island's bird population.
