 | | Herons are predators, feeding on animal life (fish, frogs, crayfish, snakes, insects, invertebrates and small rodents) found in shallow water and along the shoreline. |
 | | In spring, the great blue heron is a common migrant in March and April; in summer, a breeding resident, with the greatest concentrations of nests occurring in the northwestern counties. |
 | | The green-backed heron feeds on fish, frogs, insects, worms, lizards and salamanders, hunting early in the morning and late in the afternoon. |
