YELLOW-SHOULDERED BLACKBIRD
This endangered blackbird (Agelaius xanthomus) doesn't live exclusively in Puerto Rico's mangrove forests—it can also make a home in pastures and seashore cliffs. But because its other habitat has suffered heavy losses, largely due to expanding agriculture and development, it has become more dependent on the mangrove retreats.
RED-VENTED COCKATOO
Also known as the red-vented cockatoo (owing to its red under-tail feathers), the Cacatua Haematuropygia is native to the Philippine archipelago. Trapping the rare birds for illegal trade as pets—along with habitat loss—has led to its current IUCN status of "critically endangered".
MADAGASCAR TEAL
Madagascar teals, also called Bernier's Teal (Anas bernieri) live only in mangrove forests along the west coast of this Indian Ocean island nation. The endangered ducks, which measure about 16 to 18 inches (40 to 45 centimeters) long, feed on invertebrates in the brackish waters and make their nests in the mangrove trees.
PROBOSCIS MONKEY
Although most mangrove residents are birds and reptiles, some mammals also make their home in the tangled trees, including bats and even a sloth. The distinctive proboscis monkey (Nasalis larvatus) is one of six threatened mammals that are restricted to mangrove habitats. The unusual, endangered primate, whose noses can grow to be up to seven inches (18 centimeters) long, lives in Borneo.
MANGROVE TERRAPIN
The mangrove terrapin (Malaclemys terrapin), aka the diamondback terrapin, is one of the only turtle species that can survive in brackish water and is a common coastal resident along the East Coast. But the subspecies rhizophorarum is restricted to mangrove areas in Florida and is now listed as "near threatened" by the International Union for Conservation of Nature and Natural Resources (IUCN).
