181. Luther Marsh WMA, Grand Valley, Ontario

A large marsh northwest of Toronto where you can find waterfowl, songbirds, bitterns, cranes, terns, and more.

A recent memorable birding day for me began at dawn on a day in late May at Luther Marsh. I was participating in Bird Studies Canada’s annual Baillie Birdathon. I wanted to see how many species I could count in 24 hours during breeding season. By 12:30 p.m., I had observed 76 species, including American Bittern, Le Conte’s Sparrow, and Mourning Warbler.

Luther Marsh is one of southern Ontario’s most significant wetlands. It was created in the 1950s by a manmade impoundment on the Grand River, and soon the wetlands attracted waterfowl species usually seen farther west. Naturalists and hunters took notice, leading to the marsh’s designation as a wildlife management area in 1962.

It covers more than 13,000 acres and provides important habitat for waterfowl, herons, rails, and many other birds. At Mallard Pond, near the east edge of the marsh, I saw Black Tern, which is declining in Ontario yet continues to nest at Luther Marsh. The trail leading from the entrance is great for woodland species. On my birdathon day, it produced sparrows, orioles, warblers, grosbeaks, kingfishers, and Sandhill Crane. — Van Waffle
