In what region did the Sika deer that are now found on the Tibradden Mountain originate?
Sika deer The sika deer ("Cervus nippon") also known as the spotted deer or the Japanese deer, is a species of deer native to much of East Asia, and introduced to various other parts of the world. Previously found from northern Vietnam in the south to the Russian Far East in the north, it is now uncommon in these areas, excluding Japan, where the species is overabundant.
Sitka deer The Sitka deer or Sitka black-tailed deer ("Odocoileus hemionus sitkensis"), is a subspecies of mule deer ("Odocoileus hemionus"), similar to the Columbian black-tailed subspecies ("O. h. colombianus"). Their name originates from Sitka, Alaska, and it is not to be confused with the similarly named sika deer. Weighing in on average between 48 and , Sitka deer are characteristically smaller than other subspecies of mule deer. Reddish-brown in the summer, their coats darken to a gray-brown in mid-late August. They are also good swimmers, and can occasionally be seen crossing deep channels between islands. Their average life span is about 10 years but a few are known to have attained an age of 15.
