Galapagos boasts three species of heron among the shore birds and waders. Two species, the familiar great blue heron and the yellow- crowned night heron are found elsewhere, but the lava heron is a unique, endemic species. It can be found along the shores and tidal areas where it preys on the ubiquitous red sally lightfoot crabs, but it is easy to miss because it blends in so well with the black lava rocks for which it is named. Juveniles, however, are easier to spot because of their speckled, golden-brown plumage.
