The Orange-headed thrush should probably be called the orange-head-and-bodied thrush with bluish-grey wings if accuracy was an issue. It is a common woodland resident across India and Southeast Asia.

It is a ground feeder and feeds on insects, spiders and the like.

Crab-Eating Macaque

Crab-Eating Macaque (Macaca fascicularis)

Observed By: Jonathan Milnes, David Vinot, Everyone!

You can’t miss Koh Chang’s macaque monkeys, they seem to be everywhere. But this didn’t used to be the case. There are two possible reasons for this. Firstly they might have been hunted for food back in the days before National Park protection. Secondly these monkeys are a species that is an opportunitsic hunter and scavenger that adapts very well to living off the waste that comes with human development. So whilst it is a species that is native to Koh Chang’s environment numbers have grown rapidly around the tourist centres of Koh Chang as the source of food around here is abundant.

This species of Macaque, also known as the Long-tailed Mazaque for obvious reasons, is plentiful and not at all threatened precisely because of this affinity with human environments. In fact they can be something of a pest and you most definitely shouldn’t feed them. Here’s why;

– Crab-eating Macaques are quite at home on Koh Chang and have no problem acquiring their own food
– Monkeys are wild animals, not pets
– They bite
– They can also carry rabies and other deadly diseases
– They are often run over by cars
– The Jungle Book was a Disney cartoon not a documentary

So be very careful around these Monkeys, enjoy watching them but keep your distance. Imagine there was a wild tiger standing next to you, or an angry King Cobra, or a pack of rats. Or all three.

Common Mock Viper

The Common Mock Viper is a small species of snake that grows up to 65 cm in length. It is native to Asia.

Perhaps the most startling fact about this species is that the male posesses three penises. Really. You’d think that this would be a problem for a snake but the specially evolved hemipenis can be retracted when not in use. Only one of the three hemipenes is used at a time and they commonly have barbs or hooks. It is truly a strange and  amazing world.

As its name suggests the mock viper resembles a viper but does not come from the same family. It is rear fanged and possesses a very mild venom that isn’t harmful to humans.

What a brilliant picture this is of the splendid Asian water dragon. This mighty lizard can grow up to 1 metre in length and live for up to fifteen years.

These lizards are most commonly found along the banks of freshwater streams and are mainly tree-dwelling (arboreal) living and active mainly in the daytime (diurnal).

Kukri Snakes or Oligodon are a genus of snakes that comprise 75 species. And this is one of them. They live mainly by stealing the eggs of birds and reptiles and typically are less than 1.5 metres in length.

They are not venomous or considered dangerous to hymans. They have large teeth at the back of their throats that are specially adapted to slicing open aggs as they are being swallowed and thereby speeding up digestion.

The name of this tiny freshwater turtle is probably longer than the animal itself. The species is native to Cambodia, Southeast Thailand and Vietnam.

It is apparently nearly indistinguishable from the Eastern Black-Bridged Leaf Turtle.

This checkered keelback is giving an excellent demonstration of how snakes can dislocate their jaws to swallow very large meals – a handy skill.

This species is a large nonvenomous snake that is also known as the Asiatic Water Snake.

This fierce looking lizard sports a black mask-like marking around its eyes as well as a crest of yellow spines down its neck and back and intricately patterned scale markings.

It is apparently a very local species to Koh Chang being found only in Eastern Thailand and the Cardamom Mountains of Western Cambodia (hence the name Cardomomensis). It is also a relatively newly discovered species and we’re certainly lucky to have it as a fellow Koh Chang resident.
