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.
Mobile logperch
Juveniles eat organisms such as rotifers, copepods, and waterfleas. As they grow, they incorporate a greater variety of small aquatic creatures. They eat mostly aquatic insects (especially mayfly and midge larvae), and also may eat young snails, waterfleas, leeches, and fish eggs (including their own) when available. "Percina" show broad diversity of reproductive behavior and life history traits. Large numbers of reservoir-based individuals frequently migrate upstream into small flowing streams from late February into May to spawn (in Carrolls Creek, a tributary of Lake Tuscaloosa, Alabama). Females are thought to bury eggs in riffles or shoals of sand or gravel. Mobile logperch may live three to four years. They sometimes fall prey to piscivorous fish (more often in lakes than in streams). These fish include lake trout, walleye, rock bass, largemouth bass, burbot, and northern pike. When they spend time in slow and shallow water, they also are eaten by fish-eating birds, such as terns and mergansers.
