Fun Facts
Did You Know?
The species name caerulea is Latin for "blue," and the genus Egretta links her to the egrets — which she is, taxonomically. "Heron" versus "egret" is a naming convention, not a biological distinction, and the little blue heron could just as accurately be called the little blue egret. She wasn't, probably because she's blue and the word "egret" carried an association with white plumage that didn't fit. The common name is honest: she's little (compared to the great blue heron), and she's blue (eventually)
If This Animal Could Talk...
"Watch closely, respect my space, and let my habitat explain the rest of the story."
What is that small white heron that doesn't quite look like a snowy egret and doesn't quite look like anything else in the swamp? That's a juvenile little blue heron, and she's about to have the most confusing adolescence in all of North Louisiana birding.
The little blue heron (Egretta caerulea) is a medium-sized, slate-blue heron who stands about two feet tall and hunts the shallows of North Louisiana's swamps, bayous, and farm ponds with a slow, methodical patience that makes her easy to overlook. As an adult, she's not hard to identify — dark blue-gray body, purplish-maroon head and neck, dark-tipped greenish bill, and greenish legs. No other small heron in our range wears that particular shade of moody blue. The problem isn't the adults. The problem is the kids.
A Few More Facts
How they hunt and forage: The little blue heron is a patient, methodical forager who wades through shallow water with slow, deliberate steps, pausing frequently to scan the water surface before striking at prey with a quick bill thrust. The diet includes small fish, CRAWFISH, frogs, tadpoles, aquatic insects, snails, and small crustaceans. Little blue herons tend to forage in shallower water than great blue herons but at similar depths to snowy egrets, which creates foraging overlap between the two species and partly explains why juvenile little blue herons benefit from associating with snowy egret flocks — they're hunting the same prey in the same water at the same depth, so joining the group gives the juvenile access to proven foraging habitat without the effort of finding it independently.
Live birth or eggs? no
When young are born: The chicks grow quickly and fledge at about 35 days, joining the post-fledging flocks of juvenile herons that forage around the rookery periphery through the summer.

Little blue herons are moderately accessible, though their preference for shaded, vegetated margins makes them slightly harder to observe than the open-water specialists like great egrets and snowy egrets. The dark adults blend into swamp shadows, but the white juveniles stand out like their egret cousins.
For visitors with mobility considerations, little blue herons can be observed from auto tour routes at NWRs and from vehicle-accessible roads bordering swamps, bayous, and farm ponds. The shaded boardwalk at Black Bayou Lake NWR passes through prime little blue heron habitat. Reservoir boat ramps may provide vantage over foraging birds during low-water periods. Because little blue herons often forage along densely vegetated edges, patience and careful scanning are more important than finding the right vantage point.
For visitors with vision considerations, adult little blue herons are dark-plumaged and can be difficult to spot against shadowed swamp backgrounds without optics — she blends into the landscape in a way that the bright white egrets simply don't. Binoculars or a spotting scope significantly improve detection, especially along the heavily vegetated edges where adults prefer to forage.
The white juveniles are much easier to spot, and their presence within mixed white-heron flocks makes them detectable at the same distances as snowy egrets and great egrets — look for the bird whose legs are the wrong color and whose foraging speed is noticeably slower than the snowy egrets around her. The little blue heron's call is a low, soft croak — quieter than most other herons and not a reliable auditory cue for detection at distance.

A calico-phase little blue heron — splotched with random patches of white and blue like a molting dalmatian — is one of the most bizarre-looking birds you'll ever see in North Louisiana, and also one of the most instantly identifiable, because nothing else on Earth looks like that.
