Its streaked, brown plumage acts as camouflage while hunting fish, frogs, and insects.

The American Bittern is found across the western and eastern US. It winters along the Pacific and Gulf Coasts. It breeds across Canada and Alaska. The bird lives in freshwater marshes with dense vegetation, reedy lakeshores, and coastal wetlands.

Its diet consists of fish, amphibians, insects, aquatic invertebrates, and small mammals.

With patience, you may spy this elusive heron species perfectly adapted to life in the marsh.

Black-crowned Night-Heron

You’ll often see the stocky, quawk-prone black-crowned night-heron stalking wetlands at dusk when you’re out birdwatching.

• Prefers feeding at night due to its large eyes adapted to low light. Its peak activity begins at twilight when it starts hunting.
• Nests in colonies up high in trees to be safe from predators. Uses sticks to build platform nests.
• Hunts by slowly stalking prey or standing still waiting to ambush. Has a diverse diet from crustaceans to small rodents.
• Adult plumage is gray and white with a black crown and back. Juveniles are brown and streaked until age 2.

The black-crowned night-heron blends into wetland shadows to ambush prey under cover of darkness. Its unique adaptations allow it to fill an essential nocturnal niche. Next time you’re out at dusk, listen for its loud quawk or scan the tree canopy to catch a glimpse of this crepuscular heron.

Green Heron

You’d spot the small Green Heron stalking prey in shallow wetlands at dawn or dusk in California, using twigs as tools to hunt fish with its unique skeow call. Though diminutive, this resourceful heron exhibits fascinating behaviors. It freezes motionless to ambush small fish, frogs, and insects, then strikes with lightning speed.

Green Herons are the only North American herons to use bait, dropping insects, feathers or other items to lure fish close for capture.

Green Herons breed in wetlands across the southern United States. After building a platform nest, the female lays 3-5 eggs. Chicks hatch in about 3 weeks and fledge in another 3 weeks. Both parents feed the young by regurgitating food into their mouths.

This small heron migrates south for the winter but can be spotted year-round in parts of coastal California. Protecting fragile wetland ecosystems preserves crucial Green Heron feeding grounds and nesting sites.

When you encounter a Green Heron’s vibrant colors and cunning hunting techniques, you gain insight into nature’s infinite creativity.

Great Egret

Look around any wetland in California and you’ll spy the snowy Great Egret drifting like ghost through the reeds.

• Plumes waving like feathery plumes in their nuptial dances
• Crisscrossing ribbons of birds flying out to wetland feeding grounds
• Gangly chicks clamoring to be fed fish, frogs, and insects

Great Egrets nearly vanished in the plume trade, but are recovered conservation success stories. Their magic remains undimmed in the golden light of a summer evening, these spectral figures threading waterways fringed with tules.

Gliding on broad wings, daintily plucking prey with their long yellow bills, they epitomize the wild grace of California’s wetlands.

Cattle Egret

You’re right, the Great Egret is a stunning sight with its elegant plumes and stealthy hunting. Now let’s turn our gaze to the smaller, more social Cattle Egret. As its name suggests, this species has cleverly adapted to foraging alongside livestock.

Their short, thick bills make them well-suited to snatching insects stirred up by the animals.

Though they nest colonially, Cattle Egrets may wander far from the rookery when feeding. In winter, massive flocks travel from breeding grounds in the central and eastern U.S. to wintering sites in California and Mexico. Their migration is quite the spectacle.

Here is more on this opportunistic species:

Behavior	Migration	Diet
Forages near cattle and farm equipment	Short-distance migrant within North America	Mainly insects
Nests colonially	Winters along Pacific Coast	Some amphibians and reptiles
Forms large flocks in nonbreeding season		Carrion

Cattle Egrets exemplify how quickly birds can expand their range when new ecological opportunities arise. They’re a testament to the adaptability of the herons we’re privileged to host in California.

Snowy Egret

The striking Snowy Egret is a fairly common sight around shallow wetlands and estuaries along the entire Pacific Coast. Agile and slender, this elegant heron stirs up prey by vigorously shuffling its bright yellow feet, a singular behavior that allows it to snatch small fish, frogs, and insects from muddy shallows throughout its range in fresh and saltwater marshes.

Range and Habitat of the Snowy Egret

The snowy purity of its plumage conceals a fierce hunter, seeking prey amidst the waterways’ murky depths.

• Graceful yet fierce, it stalks the shallows with singular focus.
• Yellow feet stir silently below, sensing the pulse of life.
• A spear-like strike betrays its patience, rewarded at last.
