What heron species are found in Maine?
Maine hosts four regularly occurring heron species: the great blue heron, green heron, black-crowned night-heron, and great egret (an egret is a type of heron). The great blue heron is by far the most widespread, standing about 4 feet tall with a gray-blue body and black stripe above the eye. The green heron is smaller, stocky, with a dark green cap and chestnut neck. Black-crowned night-herons are compact, with a black back and crown, and red eyes. Great egrets are all white with a yellow bill and black legs, often mistaken for snowy egrets but larger. For detailed field marks, see theheron identification hub.
Where in Maine are herons most often seen?
Your best odds for spotting herons are along the southern and mid-coast regions, especially around Rachel Carson National Wildlife Refuge, Scarborough Marsh, and the tidal estuaries near Boothbay. Inland, look for great blues along the Kennebec River, Moosehead Lake shores, and larger beaver ponds. Green herons favor wooded streams and small ponds with overhanging vegetation. Night-herons are most reliable in coastal marshes and islands like those in Casco Bay. Check local sightings on theMaine wildlife pagefor recent reports.
What is the best time of year to see herons in Maine?
Late April through early September offers the highest chances for all species. Great blue herons arrive as early as mid-March and stay until October, but nesting activity peaks in May and June, making them more visible at rookeries. Green herons and great egrets are summer residents, best seen from May to August. Black-crowned night-herons are present from April to September, with most activity at dusk. For winter, only a few great blues linger along the open coast; most head south.

How can you tell apart great blue herons and little blue herons?
Great blue herons are large, gray-blue with a white face and black plume, whereas little blue herons are slate blue all over with a darker bill and legs, and are much smaller (about 2 feet tall). Juvenile little blue herons are white, confusing them with snowy egrets, but they have a gray bill tip and dusky legs. Great blues have a distinct 'S' curve in their neck and a dagger-like yellow bill. Little blues are very rare in Maine; if you see a small, dark heron, it is almost certainly a green heron instead.
Do any rare herons visit Maine?
Yes, a few less common heron species appear each year. The tricolored heron, snowy egret, and cattle egret are occasional visitors, mostly along the southern coast. Tricolored herons are slender with a white belly and neck stripe, snowy egrets have black bill and yellow feet, and cattle egrets are stocky with an orange wash in breeding season. Keep an eye on sandbars and shallow tidal pools, especially after spring storms. Most sightings are from May to September and are reported on local birding lists.
What gear helps for a Maine heron-spotting trip?
A good pair of binoculars (8x or 10x) is essential for distinguishing field marks from a distance. A field guide to northeastern birds or a bird ID app helps confirm species. Wear neutral colors and pack a rain jacket for coastal fog. If you plan to sketch or photograph, consider a lightweight spotting scope.
