Puerto Egas, Santiago Island, GALAPAGOS ISLANDS
ECUADOR. South America
ENDEMIC TO THE ISLANDS
These herons feed in the characteristic fashion of a 'sit and wait' predator. They eat small crustaceans like Sally lightfoot crabs. They lay one egg in a rocky crevice or in mangrove strands.
Sally Lightfoot crabs are the scavengers of the coast. They feed on anything from sealion placenta to other crustaceans. They play an important role in keeping the shores clear of organic detritus.
