Sika deer (Cervus nippon) Report Abuse
From Asia, this deer is one of the few species that do not lose their spots at maturity. A pair that was a gift from King Edward VII in the 1900's escaped into the Sowley Wood and became so prolific they began culling in the 1930's. In areas where they live alongside the native Red Deer there is a serious conservation concern as the two will hybridise.
