Lava heron

The Lava heron, also known as the Galápagos heron, is a species of heron endemic to the Galápagos Islands. The adult is slate-grey, which helps it blend in with the hardened lava. The back feathers typically have a silvery sheen and it has a short crest on its head. When breeding, the heron has a black beak and bright orange legs, but they fade to grey after the breeding season. Lava Herons are typically seen hunched over and they have a sharp alarm call. These highly territorial birds are found in intertidal zones and mangrove groves on all of the Galápagos Islands.
