Brought in from Europe as an ornamental addition to parks and estates, the Mute Swan has established itself in a feral state in some parts of North America, mainly in the northeast. In some places, it has become common enough to be unpopular, and it is considered a pest in a few areas. Not really 'mute'; its voice is hoarse and much quieter than those of our native swans, but its wingbeats may be heard as much as a mile away.
