Most country boys, I fancy, know the marsh hawk. It is he you see flying low over the fields, beating about bushes and marshes and dipping over the fences, with his attention directed to the ground beneath him. He is a cat on wings. He keeps so low that the birds and mice do not see him till he is fairly upon them. The hen-hawk swoops down upon the meadow-mouse from his position high in air, or from the top of a dead tree; but the marsh hawk stalks him and comes suddenly upon him from over the fence, or from behind a low bush or tuft of grass. He is nearly as large as the hen-hawk, but has a much longer tail. When I was a boy I used to call him the long-tailed hawk. The male is a bluish slate color; the female a reddish brown, like the hen-hawk, with a white rump. Unlike the other hawks, they nest on the ground in low, thick marshy places. For several seasons a pair have nested in a bushy marsh a few miles back of me, near the house of a farmer friend of mine, who has a keen eye for the wild life about him. Two years ago he found the nest, but when I got over to see it the next week, it had been robbed, probably by some boys in the neighborhood. The past season, in April or May, by watching the mother bird, he found the nest again. It was in a marshy place, several acres in extent, in the bottom of a valley, and thickly grown with hardhack, prickly ash, smilax, and other low thorny bushes. My friend brought me to the brink of a low hill, and pointed out to me in the marsh below us, as nearly as he could, just where the nest was located. Then we crossed the pasture, entered upon the marsh, and made our way cautiously toward it. The wild thorny growths, waist high, had to be carefully dealt with. As we neared the spot I used my eyes the best I could, but I did not see the hawk till she sprang into the air not ten yards away from us. She went screaming upward, and was soon sailing in a circle far above us. There, on a coarse matting of twigs and weeds, lay five snow-white eggs, a little more than half as large as hens' eggs. My companion said the male hawk would probably soon appear and join the female, but he did not. She kept drifting away to the east, and was soon gone from our sight.
