Observed By:Dave Hinchliffe
A fiddler crab, sometimes known as a calling crab, may be any of approximately 100 species of semi-terrestrial marine crabs which make up the genus Uca. As members of the family Ocypodidae, fiddler crabs are most closely related to the ghost crabs of the genus Ocypode. This entire group is composed of small crabs – the largest being slightly over two inches across. Fiddler crabs are found along sea beaches and brackish inter-tidal mud flats, lagoons and swamps. Fiddler crabs are most well known for their sexually dimorphic claws; the males’ major claw is much larger than the minor claw while the females’ claws are both the same size.
…and seeing a bunch of them in mating season prancing around and jousting with each other like single males in a village disco is a very entertaining sight.

Slow Worm (Anguis fragilis)

Last Observed: December 2015

OK get ready. The slow worm isn’t actually a worm. And it isn’t a snake. It is actually a lizard without any legs that isn’t a snake. Yes they exist, this is one. Got it?
The Anguis fragilis, or slow worm, is a limbless lizard native to Eurasia. It is sometimes called a blindworm. Its German name, “Blindschleiche”, is derived from the Old High German plintslîcho meaning “blinding creeper”, perhaps because of its lustrous scales.
Slow worms are semifossorial (burrowing) lizards, spending much of the time hiding underneath objects. The skin of slow worms is smooth with scales that do not overlap one another. Like many other lizards, slow worms autotomize, meaning that they have the ability to shed their tails to escape predators. While the tail regrows, it does not reach its original length. They are common in gardens and can be encouraged to enter and help remove pest insects by placing black plastic or a piece of tin on the ground. On warm days, one or more slow worms will often be found underneath these heat collectors. One of the biggest causes of mortality in slow worms in suburban areas is the domestic cat, against which it has no defense.

Black-Headed Bulbul (Pycnonotus atriceps)

Last Observed: December 2016 – Koh Chang
Last Observed By: Paul Dunn
The black-headed bulbul (Pycnonotus atriceps) is a member of the bulbul family of passerine birds. It is found in forests in south-east Asia. It has a mainly olive-yellow plumage with a glossy bluish-black head. A grey morph where most of the olive-yellow is replaced by grey also exists. The distinctive taxon from the Andamans has most of the head olive, and is increasingly treated as a separate species, the Andaman bulbul, (P. fuscoflavescens). The black-headed bulbul resembles the black-crested bulbul, but has blue eyes (though not reliable in juveniles), a broad yellow tip to the tail, and never shows a crest (however, some subspecies of the black-crested are also essentially crestless, but they have red or yellow throats). The black-headed bulbul mainly feeds on small fruit and berries, but will also take insects. It commonly occurs in small flocks, comprising 6-8 individuals.
Don’t confuse the black-headed bulbul, which has a black head, with teh black-crested bulbul, which has a black head and a black crest, or ornithologists will scorn you.

Their body colour ranges from grey-brown to blue-brown. Lesser false vampire bats live in rock crevices, caves, foliage and hollow trees, depending on availability, as well as hanging and sleeping on trees in general.(bush-crickets or katydids) found in China, Japan, Nepal, India, Thailand, Singapore and Indonesia.

Last Observed: December 2016 – Koh Chang
Last Observed By: Paul Dunn
The black-capped kingfisher (Halcyon pileata) is a tree kingfisher which is widely distributed in tropical Asia from India east to China, Korea and Southeast Asia. This most northerly of the Halcyonidae is resident over much of its range, but northern populations are migratory and they wintering south of their range to Sri Lanka, Thailand, Borneo and Java. It is distinctive in having a black cap that contrasts with the whitish throat, purple blue wings and the coral red bill. The species is mainly found in coastal and mangrove habitats but can sometimes be found far inland.
It is a medium sized bird growing up to 28cm in length.

Observed By: Paul Dunn
Kallima inachus, the orange oakleaf or dead leaf, is a nymphalid butterfly found in tropical Asia from India to Japan. With wings closed, it closely resembles a dry leaf with dark veins and is a spectacular and commonly cited example of camouflage. It’s also a very rare case where the butterfly looks more interesting with its wings closed rather than open.
