Lava Heron (Butorides sundevalli)

Also known as the Galapagos Heron, the lava heron is a species of heron (Ardeidae) which as evidenced by its common name is endemic to the Galapagos Islands. It earns its other common name due to its gray coloration which helps it blend into its hardened lava background. Lava herons usually inhabit intertidal zones and mangrove groves where they will catch fish and crabs by spearing them.
