Michigan is home to diverse heron species, including the iconic Great Blue Heron, elusive Green Heron, and elegant Great Egret. These birds inhabit the state’s wetlands, lakes, and rivers. Herons play crucial ecological roles and face challenges like habitat loss.
Conservation efforts, including wetland restoration and citizen science programs, aim to protect these majestic birds. Michiganders can observe herons year-round, with spring and summer offering the best viewing opportunities.
Meet the Herons:
A. Great Blue Heron:
The Great Blue Heron is perhaps the most recognizable of Michigan’s heron species. Standing up to 4.5 feet tall with a wingspan of up to 6.5 feet, these majestic birds are a common sight along the shores of Michigan’s lakes, rivers, and wetlands.
Identification tips:

Habitat preferences:
Great Blue Herons are adaptable birds, found in a variety of aquatic habitats across Michigan. They prefer:
- Shallow waters of lakes and ponds
- Slow-moving rivers and streams
- Marshes and swamps
- Coastal areas along the Great Lakes
Fascinating behaviors:
These birds exhibit several intriguing behaviors that make them a joy to observe:
- Hunting technique: Stands motionless in shallow water, waiting to spear fish with their sharp bills

- Color: Dark green cap, chestnut-colored neck, and greenish-blue back
- Distinctive features: Short legs, stocky build, and a habit of crouching low when hunting
Clever fishing techniques:
Green Herons are known for their intelligence and problem-solving abilities when it comes to fishing:
- Tool use: One of the few birds known to use tools, dropping bait (like twigs or insects) on the water’s surface to attract fish
- Patient stalking: Moves slowly and deliberately through shallow water, blending in with surrounding vegetation
Where to spot them:
Look for Green Herons in:
- Small ponds and streams
- Mangrove swamps

Roosting spots in Michigan:
During the day, look for Black-crowned Night-herons roosting in:
- Dense foliage of trees near water bodies

Best places for sightings:
While rare, Yellow-crowned Night-herons have been spotted in:
- Coastal wetlands along the Great Lakes
- Large river systems in southern Michigan
- Occasionally in urban areas with suitable habitat
E.American Bittern
The American Bittern is a secretive heron species that relies on camouflage to avoid detection.
- Identification: Brown streaked plumage, thick neck, and yellow eyes
- Behavior: Often stands motionless with its bill pointed upward, blending in with surrounding reeds
- Habitat: Dense marshes and wetlands with tall vegetation
- Vocalizations: Known for its unique “pump-er-lunk” call, which sounds like an old water pump

Meet the Egrets: Heron’s Elegant Cousins
An egret is a type of heron. Egrets are generally distinguished from other herons by their white plumage and slender bodies. They belong to the same family and share many characteristics with herons, such as their long legs and necks, and their habitat preferences.
A. Great Egret:
The Great Egret is a stunning white bird that rivals the Great Blue Heron in size and elegance.
Distinguishing features:
- Size: Nearly as tall as the Great Blue Heron, standing up to 3.3 feet
- Color: Pure white plumage
- Distinctive traits: Long, S-shaped neck; yellow bill; black legs and feet
Breeding plumage and courtship:
During breeding season, Great Egrets undergo remarkable changes:
- Plumes: Long, lacy plumes (aigrettes) grow from their back
- Bill color: Changes from yellow to orange
- Courtship displays: Males perform elaborate dances, raising their plumes and clapping their bills
Conservation success story:
The Great Egret serves as a symbol of conservation success in Michigan:
- Historical decline: Nearly hunted to extinction for their plumes in the late 19th century
- Recovery: Protection efforts led to a significant rebound in populations
- Current status: Now a common sight in Michigan’s wetlands, with stable populations
B. Snowy Egret:
The Snowy Egret is a smaller, more animated cousin of the Great Egret.
Identification tricks:
- Size: Much smaller than the Great Egret, standing about 2 feet tall
- Color: Pure white plumage
- Distinctive features: Black bill with yellow lores (area between eye and bill); black legs with yellow feet (often described as wearing “golden slippers”)
Unique foraging behaviors:
Snowy Egrets are known for their active and sometimes comical feeding techniques:
- Foot-stirring: Using their bright yellow feet to stir up prey in shallow water
- Canopy feeding: Running with wings spread to create shade, attracting fish
- Aerial chases: Pursuing flying insects with acrobatic flights
Historical plume trade impact:
Like the Great Egret, Snowy Egrets were heavily impacted by the plume trade:
- Near extinction: Populations plummeted in the late 19th and early 20th centuries
- Recovery: Protected by the Migratory Bird Treaty Act of 1918
- Current status: Now increasing in numbers and expanding their range northward into Michigan

Adaptability to human-altered landscapes:
These egrets demonstrate remarkable adaptability:
- Habitat preferences: Agricultural fields, pastures, and urban parks
- Nesting: Often form colonies with other heron species
- Range expansion: Continues to expand northward, likely aided by climate change
D.Little Blue Heron:
The Little Blue Heron is an occasional visitor to Michigan that offers a unique identification challenge.
Juvenile vs. adult plumage:
One of the most intriguing aspects of Little Blue Herons is their dramatic color change:
- Juveniles: Pure white plumage, often mistaken for Snowy Egrets
- Adults: Slate-blue body with purplish head and neck
- Transition: Occurs over the first year, resulting in a “calico” appearance
Habitat preferences in Michigan:
When present in Michigan, Little Blue Herons can be found in:
- Coastal marshes along the Great Lakes
- Inland wetlands and swamps
- Occasionally in flooded agricultural fields
Identification challenges:
Distinguishing Little Blue Herons from other heron species can be tricky:
- White juveniles: Look for greenish-yellow legs (vs. black legs with yellow feet in Snowy Egrets)
- Adults: Can be confused with Green Herons at a distance; look for the larger size and lack of green tones
E. Sandhill Crane
While not a heron, the Sandhill Crane is often mistaken for one due to its similar size and habitat preferences.
- Identification: Gray body, red forehead, long neck and legs
