Red crab migration

The red crab is by far the most obvious of the 14 species of land crabs on Christmas Island. Every year over 150 million red crabs move from inland shelters to the shore for their annual breeding season. This occurs at the beginning of the wet season (usually October/November).

The main migration can last up to 18 days. Masses of crabs gather into broad columns as they move toward the coast, climbing down high inland cliff faces, and over or around all obstacles in their way, following routes used year after year for both downward and return migrations.

Movement peaks in the early morning and late afternoons when it is cooler and there is more shade. Because if caught in open areas, in unshaded heat, the crabs soon lose body water and die.

Christmas Island is a small Australian-owned territory located in the Indian Ocean, approximately 300 miles south of Jakarta, Indonesia. A small population of 1600 residents live on the area of 50 square miles.

Red-capped Manakin - The Moonwalking bird

It is found in Belize, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Peru and Panama. Its natural habitat is subtropical or tropical moist lowland forests. The bird is probably best known for the male’s unusual courting method whereby it shuffles rapidly backwards across a branch, akin to a speedy moonwalk.
