Virginia rail
The Virginia rail probe with its bill in mud or shallow water, also picking up food by sight. It mainly eat insects and other aquatic invertebrates, like beetles, flies, dragonflies, crayfish, snails and earthworms. It can also eat aquatic animals like frogs, fish and some small snakes, as well as seeds. Animal preys constitute the biggest part of this bird's diet, but vegetation contributes to its diet in the fall and winter.
Water buffalo
Water buffalo thrive on many aquatic plants. During floods, they will graze submerged, raising their heads above the water and carrying quantities of edible plants. Water buffalo eat reeds, "Arundo donax", a kind of "Cyperaceae", "Eichhornia crassipes", and "Juncaceae". Some of these plants are of great value to local peoples. Others, such as "E. crassipes", are a major problem in some tropical valleys and water buffalo may help to keep waterways clear.
