Juvenile stone plover, avocet, pied oystercatcher, and lotus bird
These birds are all waders, which largely live in wetland or coastal environments. The lotus bird is able to stride atop the lilypads and other wetland flora, thanks to its long toes, which distribute its weight over a large area. The other waders walk along the water bottom for the most part, and rarely venture beyond still shallows.
