What is it?

The Formosan sika deer is a small, gentle deer that lives only in Taiwan. It has a reddish-brown coat covered in pretty white spots, like a sprinkle of stars on its back. The spots help it hide in dappled sunlight under trees. Adults are about the size of a large dog.

Tell me more

Formosan sika deer once roamed all across the plains and low forests of Taiwan in enormous herds. About a hundred years ago, they almost disappeared from the wild. People realised what was happening and decided to do something about it. A small group of deer were carefully looked after in parks, and slowly their numbers began to grow again.

Today, thanks to those efforts, there are several wild herds living in protected places like Kenting National Park in southern Taiwan. The deer have learned to live in coastal forests, near grasslands and even close to villages. Park rangers keep track of them and make sure they have plenty of food and water.

Baby sika deer are born in early summer, covered in extra-bright white spots. The spots are so clear at first that they almost glow. The babies stay hidden in the long grass for the first few weeks while their mothers come to feed them. The spots blend in with the spots of sunlight that fall through the leaves.

Males grow antlers each year - big branching ones that look almost like the bare twigs of a tree. The antlers fall off in late winter and brand new ones grow back, a little bigger than before. By autumn they have a full new pair, ready to use.

Discussion prompts

  1. 01Why might spots that look like dots of sunlight be helpful for a baby deer in the forest?
  2. 02People helped sika deer come back from almost disappearing. What does that tell us about what humans can do for wild animals?
  3. 03Antlers fall off and grow back every year. What other parts of plants and animals do you know that grow back?

Classroom activity

On a sheet of brown paper, paint or stick on white spots in random patterns. Hold the paper under a tree and look at it through dappled light. Can you see how the spots blend with the sunlight? Discuss why camouflage is one of nature's cleverest tricks.
