Great Blue Heron

Ardea herodias ORDER: PELECANIFORMES FAMILY: ARDEIDAE

IUCN Conservation Status: Least Concern

Whether poised at a river bend or cruising the coastline with slow, deep wingbeats, the Great Blue Heron is a majestic sight. This stately heron with its subtle blue-gray plumage often stands motionless as it scans for prey or wades belly deep with long, deliberate steps. They may move slowly, but Great Blue Herons can strike like lightning to grab a fish or snap up a gopher. In flight, look for this widespread heron’s tucked-in neck and long legs trailing out behind.

Calls

Great Blue Herons are most vocal on the breeding grounds, where they greet their partner with squawking roh-roh-rohs in a “landing call” when arriving at the nest. A disturbance can trigger a series of clucking go-go-gos, building to a rapid frawnk squawk that can last up to 20 seconds. If directly threatened, birds react with a screaming awk lasting just over 2 seconds. Chicks give a tik-tik-tik call within minutes of hatching.

Other Sounds

Both male and female Great Blue Herons snap their bill tips together as part of breeding and territorial displays, a behavior that may be analogous to a songbird’s territorial song. Paired birds often “clapper” at each other, chattering the tips of the bill together.

Backyard Tips

Great Blue Herons aren’t likely to visit a typical backyard. However, they are sometimes unwelcome visitors to yards that include fish ponds. A length of drain pipe placed in the pond can provide fish with a place to hide from feeding herons. Herons, like most of our birds, are legally protected by the Migratory Bird Treaty Act.

If you are near appropriate habitat, consider building a nest platform to attract herons. You can get plans for Great Blue Heron nest platform on our All About Birdhouses site.

Find This Bird

Scan shorelines, river banks, and the edges of marshes, estuaries, and ponds across much of the U.S. for this tall, slow-moving heron. Great Blue Herons also feed in meadows, farmland, and other open fields. Some colonies or “heronries” are found near developed areas; look for the herons’ bulky stick nests high in trees. And once you recognize their slow wingbeats and massive silhouettes, you’ll start to notice these birds in flight high in the sky as well.
