Night Herons Breeding on the Marsh

While collecting on the marsh I noticed many Night Herons, and enquired of the hunters and trappers if they found any nests in the trees on the islands in the marsh, but they did not, but had found the nesting place on the marsh. I went for them with a boy for guide. We rowed up a channel as near the place as possible, when they began to leave their nests in the grass and rushes. When forty rods off we left the boat and waded. The bogs are a kind of floating sod, with two or three feet of mud and water under them, and sink at each step. The first nest was in the rushes and built of rushes, about one foot high and about the same width, with just hollow enough to keep the eggs from rolling out. Other nests were in the grass, but most of them were in the cat tail flags, in holes which had been burned in the dry time. The nests in the flags were built of pieces of flags, both leaves and stalk. Those in the grass were built of rushes and flags. The nests contained from one to five eggs each, but mostly three—two sets of five and a number with four. I took about forty sets that day—the larger sets were incubated, but about half were fresh. I went a second time to the marsh and got a lot of eggs.—Delos Hatch, Oak Centre, Wis.
