There are six living and many extinct species of swan; in addition, there is a species known as the coscoroba swan which is no longer considered one of the true swans. Swans usually mate for life , although separation sometimes occurs, particularly following nesting failure, and if a mate dies, the remaining swan will take up with another.
In winter, they may eat crop remnants in agricultural fields, but more commonly they feed while swimming. These birds feed while swimming, sometimes up-ending or dabbling in reaching submerged food. The diet is almost entirely aquatic plants and occasionally insects. [34] They will eat both the leaves and stems of submerged and emergent vegetation.

The Swans, then you probably watched (spoiler alert) Truman himself eating an actual swan. In episode five, he hires a private chef to covertly steal a swan from Central Park and kill and cook it.
Trumpeter swan on nest. Order: Anseriformes Family: Anatidae. The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.
This list includes all bird species known to have occurred in the state, including birds that don't breed in Connecticut, such as migrants, winter visitors and vagrants, as well as breeding species and recently extinct and extirpated species. There are about 280 species that are recorded consistently every year in the state.
The mute swan is less vocal than the noisy whooper and tundra swans; they do, however, make a variety of sounds, often described as "grunting, hoarse whistling, and snorting noises." During a courtship display, mute swans utter a rhythmic song.
