When we travel to countryside. wetland near the Mississippi river, we saw a heron. We thought it was a Louisiana heron.
Fig 01- A heron, nearby Mississippi river.
However, the GoogleID identified it is a great blue heron with scientific name, Ardea herodias. While the Louisiana heron has different scientific names that is Egretta tricolor. Both species are native to the Louisiana state.
We may observe the great blue herons in their natural habitats such as lakes, rivers, swamps and marshes areas.
The bird is a predator with diverse food sources, but dominant diet is fish, from catfish to eel to minnow. Other diets include reptiles (lizards), amphibians (frogs), invertebrates, small mammals and small birds.
Interestingly, great blue herons are patient predators, they may stand still for long time to wait for fish swimming by.
The great blue heron may consume quite big quantity, could be several kg of fish per day.
Do you know about great blue herons?
