This ridge of higher ground proved to be a mosquito roost—a thousand here to one in the deeper, denser grass. As I hurried across I noted with great satisfaction that the pink-white blossoms of the spreading dogbane were covered with mosquito carcasses. It lessened my joy somewhat to find, upon examination, that all the victims were males. Either they had drunk poison from the flowers, or else, and more likely, they had been unable to free their long-haired antennæ from the sticky honey into which they had dipped their innocent beaks. Several single flowers had trapped three, and from one blossom I picked out five. If we could bring the dogbane to brew a cup which would be fatal to the females, it might be a good plant to raise in our gardens along with the eucalyptus and the castor-oil plants.
Everywhere as I went along, from every stake, every stout weed and topping bunch of grass, trilled the seaside sparrows—a weak, husky, monotonous song, of five or six notes, a little like the chippy's, more tuneful, perhaps, but not so strong. They are dark, dusky birds, of a grayish olive-green hue, with a conspicuous yellow line before the eye, and yellow upon the shoulder.
There seems to be a sparrow of some kind for every variety of land between the poles. Mountain-tops, seaside marshes, inland prairies, swamps, woods, pastures—everywhere, from Indian River to the Yukon, a sparrow nests. Yet one can hardly associate sparrows with marshes, for they seem out of place in houseless, treeless, half-submerged stretches. These are the haunts of the shyer, more secretive birds. Here the ducks, rails, bitterns, coots,—birds that can wade and swim, eat frogs and crabs,—seem naturally at home. The sparrows are perchers, grain-eaters, free-fliers, and singers; and they, of all birds, are the friends and neighbors of man. This is no place for them. The effect of this marsh life upon the flight and song of these two species was very marked. Both showed unmistakable vocal powers which long ago would have been developed under the stimulus of human listeners; and during all my stay (so long have they crept and skulked about through the low marsh paths) I did not see one rise a hundred feet into the air, nor fly straight away for a hundred yards. They would get up just above the grass, and flutter and drop—a puttering, short-winded, apoplectic struggle, very unbecoming and unworthy.
By noon I had completed a circle and recrossed the lighthouse road in the direction of the bay. A thin sheet of lukewarm water lay over all this section. The high spring tides had been reinforced by unusually heavy rains during April and May, giving a great area of pasture and hay land back, for that season, to the sea. Descending a copsy dune from the road, I surprised a brood of young killdeers feeding along the drift at the edge of the wet meadow. They ran away screaming, leaving behind a pair of spotted sandpipers, "till-tops," that had been wading with them in the shallow water. The sandpipers teetered on for a few steps, then rose at my approach, scaled nervously out over the drowned grass, and, circling, alighted near where they had taken wing, continuing instantly with their hunt, and calling Tweet-tweet, tweet-tweet, and teetering, always teetering, as they tiptoed along.
If perpetual motion is still a dream of the physicist, he might get an idea by carefully examining the way the body of till-top is balanced on its needle legs. If till-tops have not been tilting forever, and shall not go on tilting forever, it is because something is wrong with the mechanism of the world outside their little spotted bodies. Surely the easiest, least willed motion in all the universe is this sandpiper's teeter, teeter, teeter, as it hurries peering and prying along the shore.
Killdeers and sandpipers are noisy birds; and one would know, after half a day upon the marsh, even if he had never seen these birds before, that they could not have been bred here. For however
candid and simple and nothing-withholding and free
the marsh may seem to one coming suddenly from the wooded uplands, it will not let one enter far without the consciousness that silence and secrecy lie deeper here than in the depths of the forest glooms. The true birds of the marsh, those that feed and nest in the grass, have the spirit of the great marsh-mother. The sandpiper is not her bird. It belongs to the shore, living almost exclusively along sandy, pebbly margins, the margins of any, of almost every water, from Delaware Bay to the tiny bubbling spring in some Minnesota pasture. Neither is the killdeer her bird. The upland claims it, plover though it be. A barren, stony hillside, or even a last year's corn-field left fallow, is a better-loved breast to the killdeer than the soft brooding breast of the marsh. There are no grass-birds so noisy as these two. Both of them lay their eggs in pebble nests; and both depend largely for protection upon the harmony of their colors with the general tone of their surroundings.
I was still within sound of the bleating killdeers when a rather large, greenish-gray bird flapped heavily but noiselessly from a muddy spot in the grass to the top of a stake and faced me. Here was a child of the marsh. Its bolt-upright attitude spoke the watcher in the grass; then as it stretched its neck toward me, bringing its body parallel to the ground, how the shape of the skulker showed! This bird was not built to fly nor to perch, but to tread the low, narrow paths of the marsh jungle, silent, swift, and elusive as a shadow.
It was the clapper-rail, the "marsh-hen." One never finds such a combination of long legs, long toes, long neck and bill, with this long but heavy hen-like body, outside the meadows and marshes. The grass ought to have been alive with the birds: it was breeding-time. But I think the high tides must have delayed them or driven them elsewhere, for I did not find an egg, nor hear at nightfall their colony-cry, so common at dusk and dawn in the marshes just across on the coast about Townsend's Inlet. There at sunset in nesting-time one of the rails will begin to call—a loud, clapping roll; a neighbor takes it up, then another and another, the circle of cries widening and swelling until the whole marsh is a-clatter.
