DNA sexed female mute swan cygnet, born 5/15/12. Parents are unrelated, she is the polish varient. She is currently the size of a duck and her juvenile feathers are just starting to grow.
We are located in SE Indiana just west of Cincinnati, OH and are willing to drive a couple hours to meet you.
Polish Mute Swan
The polish mute swan is a ‘pure white’ version of a mute swan. The legs and feet are a pinkish-grey colour instead of the usual black colour.
A pigment deficiency of a gene in the sex chromosomes is what causes the whiteness.
When a female mute swan inherits only one melanin-deficient chromosome she will be a polish swan, whereas the male of the same parents will be normal. If the next generation is produced by two of their offspring the brood will contain numbers of both polish and normal cygnets of either sex.
Polish swans were given their name when they were imported from the Polish coast on the Baltic sea into London around about 1800. Mistakenly thought to be a new species they were given the name ‘Cygnus immutabilis’ (changeless swan).
Polish swans are not a different species of swan, because they are mute swans.
