The lava heron, also known as the Galápagos heron, is a species of heron endemic to the Galápagos Islands of Ecuador. It is considered by some authorities — including the American Ornithological Society and BirdLife International — to be a subspecies of the striated heron, and was formerly "lumped" with this species and the green heron as the green-backed heron.
Region
Galápagos Islands
Typical Environment
Occurs throughout coastal habitats of the Galápagos, especially along rugged lava shorelines, mangrove fringes, and tidal pools. It favors sheltered bays, rocky coves, salt lagoons, and intertidal flats where small prey is abundant. Birds often perch on lava outcrops or mangrove roots to scan for movement. Inland records are rare and usually tied to brackish ponds close to the coast.

Also called the Galápagos heron, it blends remarkably with dark volcanic shorelines thanks to its sooty slate plumage. During breeding, its legs turn bright orange and the plumage becomes darker, almost black, with subtle glossy tones. It often hunts crabs and small fish in tidal pools formed on lava flows. Some authorities treat it as a subspecies of the striated heron.
