Three species of birds that depend entirely on wetland areas and frequently seen here at Fort Mifflin are the Great Egret, Great Blue Heron and Belted Kingfisher.
The population of Great Egrets suffered drastically during the 19th century, when they were hunted for their elegant plumage. Their long white feathers decorated fashionable ladies' hats. Today their numbers have largely recovered. If you're lucky, you may see the Great Egret stalking our moat in search of fish.
Great Blue Heron
The Great Blue Heron can stand as a statue, searching the water below for movement. It swallows its prey whole, flipping and turning it until it goes head-first down the gullet. If disturbed, the heron may give a croak-ing call and fly away.
You may first notice the Belted Kingfisher (named for the bands of color over its breast) as a low-flying, speeding object making a raucous, rattling call.
