What does a blue heron eat while sitting on her eggs?

While sitting on her eggs, a blue heron primarily relies on stored fat reserves and does not actively hunt for food. However, once she leaves the nest to forage, her diet typically consists of fish, amphibians, and small mammals. These birds are opportunistic feeders, so they may also consume crustaceans and insects depending on availability. This foraging behavior usually occurs during the early morning or late evening when prey is most active.
