They are predators of crabs, lizards, and fish. But, they do not have natural predators, but they are in continuous threat from invasive species. They move slowly and stab at their prey with the help of their pointed beaks.
They do not involve in parasitic or mutualistic relationships, though they appear to perform commensalism with penguins and lions of the same Islands. The female lava heron can lay up to 10 eggs in a year in her nest.
