Rajhans means royal swan. The white swan is the symbol of Goddess Saraswati, Goddess of divine wisdom. It is said about the mythological Rajhans royal swan that it has the power to discriminate the good from the bad, to separate milk from water. These birds are easily recognizable in addition to the size, especially for long necks have elegant demeanor and appearance of the two sexes is very similar.
The swans, such as herbivores, are in themselves harmless to humans, coming often to socialize spontaneously; However, even the specimens more accustomed to the possible contact with humans, such as those found in the bodies of water parks of historic mansions open to the public, botanical gardens, etc., can sometimes become extremely aggressive and dangerous, such as to defend themselves or territory the nest, partner, offspring, or if they perceive as hostile to the approach of someone or some animal for example dogs, which are to be kept on a leash cautiously in the presence of swans, for the good of both.
In case you have little or no previous contact with the swans or with the specimen in question - whether it is animal in captivity than in the wild is better not to approach him very much let alone try to touch him, referring to the behavior any other people who interact peacefully with him to do the same under their supervision. Suffer the aggression of a swan can lead to serious consequences.
In captivity they are guests of the zoo, parks, botanical gardens and large houses with vast open spaces and water bodies more or less natural. The plants adjacent areas frequented by swans, ornamental or not, are subject to these little damage, if they find the leaves of their food taste like.
For a private, keep this wonderful palmipede is not an undertaking for everyone, not least because of the need to have an adequate pool of water natural or artificial lake, pond or large tank), and then a piece of land large enough to contain it.
The depth of the water should be about half variable between 80 and 120 cm ie such as to allow the swimming swan stretching its legs completely, and to be able to get the nourishment on the seabed due to the long neck, present even the deepest areas where the swan will be safe from any hazards or enemies and extensive shallow areas where the swans will feed on the elements of the seabed with less expenditure of energy present shores mostly steep high 50 cm of water level, and that give hospitality to vegetation with 2 or 3 grassy beaches thinning from just inside the water 50 cm from the shore, so as to allow at those points exit and return water to the swans and cygnets any more.
In the central part of the basin is good to be covered with small islands with low coasts separated by an adequate measure of the perimeter of the lake through deep water - so that the swans can safe place in which autonomy and more secluded, useful for example to build the nest above or behind.
In ancient times, the white swan, swans and exotic black neck black, the wild and the child were bred for food: today their beauty makes them immune from this risk, but most are protected species. A park designed to accommodate a swan to be fenced, with an underground network of at least 20 cm to avoid evasion of potential intrusions or hostile animals eg foxes, dogs. Finally, we must predict the existence of one or more hospitalizations, wood or masonry, a meter high or more, where the swans can take refuge during inclement weather and lay and hatch their eggs.
As for preventing the swan in captivity to take flight - go elsewhere are often used unfortunately practices useful wings other gimmicks physical networks are flying cages perimeter, reduced or unsuitable surface for pick up speed, or obstacles vertical parking around the area that prevent its flight path, it is preferable to protect the places already visited regularly by swans in the free state, where those come cyclically, and creating new ones fit for purpose, so that you can enjoy these great volatile in the spontaneity of their being.
Any renovation of existing spaces in which people live in captivity for some time, intended to allow free access to departure and swans in the free state, should take into account that the swans lived in captivity - and in forced isolation from their peers with an additional arrival of new swans may work - or be forcibly involved in battles for territory, in which, however, would run the risk of having the worst due to the weakening of the wings, without the option of ceasing flying possibly elsewhere.
You can also use the facilities in the past used as a zoo for the swans artificially prevented the fly to give shelter to any injured specimens, without forgetting that the swan is a monogamous animal that suffers from separation from the partner.
