Mute Swans mainly eat aquatic vegetation, along with some animal prey including frogs, tadpoles, fish, snails, mollusks and insects. In a Michigan study swans ate more animals during their annual molt and in spring when vegetation was scarce. Plant foods include eelgrass, several species of pondweeds, along with filamentous algae, wigeon grass, sea lettuce, bladderwort, flowering grasses, and agricultural grains. They also eat handouts from people, including cracked corn, bread, lettuce, and produce trimmings. Mute Swans are voracious foragers, eating up to 8 pounds of aquatic plants a day that they tear off with their thick, rough-edged bills anchored by strong bill muscles. They skim plants from the surface and submerge all but their tail and feet to reach vegetation growing in deeper water. They also rake the bottom with their feet to expose tubers and dig up plants to bring to the surface. Back to top
But if there was a pleasure in all this while snugly cuddling in the chimney-corner of a chamber that was all of a ruddy glow from the crackling wood-fire, and where, of course, no spectre dared to show its face, it was dearly purchased by the terrors of his subsequent walk homewards. What fearful shapes and shadows beset his path amidst the dim and ghastly glare of a snowy night! With what wistful look did he eye every trembling ray of light streaming across the waste fields from some distant window! How often was he appalled by some shrub covered with snow, which, like a sheeted spectre, beset his very path! How often did he shrink with curdling awe at the sound of his own steps on the frosty crust beneath his feet, and dread to look over his shoulder, lest he should behold some uncouth being tramping close behind him! And how often was he thrown into complete dismay by some rushing blast howling among the trees, in the idea that it was the Galloping Hessian on one of his nightly scourings!
