According to ducks Unlimited (http://www.ducks.org/hunting/waterfowl-id) Trumpeter swans were nearly extirpated as a result of over-harvesting and the widespread destruction and degradation of wetlands. In 1932, fewer than 70 trumpeters were known to exist worldwide. Today increases in populations due to conservation effort by hunters have opened hunting opportunities for these massive birds.
