The 'ridgwayi' subspecies of the Western Osprey has fainter brown markings on the head, and is slightly smaller. It is found in the Bahamas, Cuba, and part of Belize, and is one of three subspecies of the Western Osprey. The other two subspecies cover multiple continents. The 'ridgewayi' subspecies is actually similar to the Eastern Osprey, which is even smaller and has similar markings.
A large raptor not too closely related to any another, that lives on a diet of large fish caught by diving into the water like a kingfisher, pelican or tern. Osprey's migrate, but seem to migrate until they find a place they like (some halfway across the world, while others hardly at all). The Eastern Osprey and smaller Western Osprey (found along Australia's rivers) where recently joined into one species.
