Green Herons are common and widespread, but they can be hard to see at first. Whereas larger herons tend to stand prominently in open parts of wetlands, Green Herons tend to be at the edges, in shallow water, or concealed in vegetation. They usually hunt by wading in shallow water, but occasionally they dive for deep-water prey and need to swim back to shore—probably with help from the webs between their middle and outer toes.
