What is the diet of a blue heron?

The diet of a blue heron consists primarily of fish, but they are opportunistic feeders and will also consume other aquatic creatures such as frogs, snakes, turtles, crayfish, and insects. They typically hunt in shallow waters, wading through the water and spearing their prey with their long, sharp beaks. Blue herons will also sometimes fly low over the water and snatch smaller fish or insects from the surface.
