WILD GEESE, DUCKS. AND SWANS ) National Geographic Society A VANISHING AMERICAN IS THE GREAT WHITE TRUMPETER SWAN Over lonely lake and mountain in northern British Columbia ring the low-keyed, far-carrying calls of this majestic five-foot bird (in flight), one of the continent's largest waterfowl. A few pairs survive also in Yellowstone National Park. Not man, but the marauding coyote on the nesting grounds threatens to send the trumpeter the way of the great auk and the passenger pigeon. Slightly smaller, but far more numerous, are the whistling swans (full-grown in foreground, young in water). From Arctic to Gulf they fly. Long wedges often cleave the upper air high above the earth.
