They are almost entirely herbivorous, although they may eat small amounts of aquatic animals. Traditionally, the British Monarch retains the right to ownership of all unmarked mute swans in open water, but only exercises ownership on certain stretches of the River Thames and its surrounding tributaries. Swans are often a symbol of love or fidelity because of their long-lasting, apparently monogamous relationships. Swans are birds of the family Anatidae within the genus Cygnus. According to the Prose Edda, the water of this well is so pure and holy that all things that touch it turn white, including this original pair of swans and all others descended from them. They will viciously attack anything that they perceive as a threat to their chicks, including humans. The supposed fossil swans "Cygnus" bilinicus and "Cygnus" herrenthalsi were, respectively, a stork and some large bird of unknown affinity (due to the bad state of preservation of the referred material). In the legend The Wooing of Etain, the king of the Sidhe (subterranean-dwelling, supernatural beings) transforms himself and the most beautiful woman in Ireland, Etain, into swans to escape from the king of Ireland and Ireland's armies. prudence and discrimination between the good and the bad or between the eternal and the transient. [11], Several species are migratory, either wholly or partly so. Tundra swans migrate south just before the coming of cold, snowy weather in winter and begin the return trip north as the ice melts. Their wingspans can be over 3.1 m (10 ft). Continuous feeding by a flock of mute swans can destroy an entire wetland ecosystem. [19] The pair bonds are maintained year-round, even in gregarious and migratory species like the tundra swan, which congregate in large flocks in the wintering grounds. In other words, being able to fly off and leave the parents. [14] The mute swan and black-necked swan have lumps at the base of their bills on the upper mandible. ), The Secret Science of Solving Crossword Puzzles, Racist Phrases to Remove From Your Mental Lexicon.

Breeding pairs do not moult at the same time as they, and any offspring, would be too vulnerable to attack. Given the biogeography and appearance of the subgenus Olor it seems likely that these are of a more recent origin, as evidence shows by their modern ranges (which were mostly uninhabitable during the last ice age) and great similarity between the taxa. Therefore, Goddess Saraswati the goddess of knowledge is seen riding the swan because the swan thus symbolizes "Viveka" i.e. Photograph by Kim Stevenson. A number of prehistoric species have been described, mostly from the Northern Hemisphere.

[5] Young swans are known as swanlings or as cygnets; the latter derives via Old French cigne or cisne (diminutive suffix -et "little") from the Latin word cygnus, a variant form of cycnus "swan", itself from the Greek κύκνος kýknos, a word of the same meaning. Compared to the closely related geese, they are much larger and have proportionally larger feet and necks. [33], Swan meat was regarded as a luxury food in England in the reign of Elizabeth I. The fossil record of the genus Cygnus is quite impressive, although allocation to the subgenera is often tentative; as indicated above, at least the early forms probably belong to the C. olor – Southern Hemisphere lineage, whereas the Pleistocene taxa from North America would be placed in Olor.
