The St. Andrew Vireo (also known as the San Andres Vireo) is an endangered species of vireo endemic to the Colombian island of St. Andrew in the Caribbean Sea, located off the east coast of Nicaragua. Due to habitat loss from the ever expanding population on this small island, the species has now become limited to a few localities on the southern half of the island, but it is still common in some of these areas. It is found in most habitat types on the island.
