Barbuda is a birders paradise, home to some 170 avian species, including one of the largest frigate bird colonies on the plant. Located in the vast Codrington Lagoon, which also hosts dozens of other species, off the island's northwest coast, is the Frigate Bird Sanctuary, which is home to more than 5,000 of these black-feathered birds that like to roost amid the scrubby mangroves found here. Visit the sanctuary during mating season (September to April) if possible. The birds have a fascinating ritual. While the female birds circle above, the male frigates line up in the bushes with their heads arched and chests puffed, and try to attract he attention of a potential mate. When a female frigate sees a male that she fancies she lands at his feet and begins the mating ritual. The lagoon can only be accessed by licensed sea taxi from the jetty in Codrington – boat drivers act as tour guides. Arrangements can be made through your hotel. The taxi tour costs about $70 for up to four people, and admission to the park is just $2 per person.
