About the Great Blue Heron
Great blue herons stalk shallow waters with slow, deliberate steps, spearing fish and amphibians. They nest colonially in tall trees, often cypress, returning to the same rookery each spring.

Common questions
What is a rookery and why do herons use it?
A rookery is a colony of nesting birds; great blue herons choose tall, isolated trees in swamps for safety from predators.
Can I see great blue herons outside of spring in Louisiana?
Yes, they are present year-round, but the rookery is most active with courtship and chicks from March through June.
