Sightings at Sungei Tengah
I'd spent the evening at the Animal Concerns Research & Education Society (ACRES) Wildlife Rescue Centre, and as I walked out towards Old Choa Chu Kang Road to take the bus, I stumbled upon a few examples of local amphibians and reptiles along Lorong Pasu and Sungei Tengah Road.

Hello from SG (@HellofrmSG), Singapore's very own rotation curation project on Twitter, has just been launched, and our very first curator is journalist and history buff Eisen Teo (@eisen).
As part of his self-introduction, Eisen shared the etymology of the name of his neighbourhood, Serangoon:

Thoughts on Roadkill, Part 2: Invasives & Non-natives
On Monday, the Animal Concerns Research & Education Society (ACRES) posted the following image on their Facebook page:

Green iguanas are native to Central and South America. It is saddening and shocking to sight such exotic wildlife here in Singapore, smuggled in to meet the demand for reptiles as illegal pets. This poor adult male Iguana was found run over and dead on the roads on Sungei Tengah road, right in our neighbourhood - Another victim of the illegal wildlife trade being abandoned to fend for himself.

Moving away from animals for a while, this post will look at a plant that is familiar to most of us, and is linked to dragons by name.

Year of the Dragon: Singaporean Dragons

As mentioned in yesterday's post, Singapore is home to a number of agamid lizards (F. Agamidae). This post will discuss the several species of agamids that are found here.

Ball-cutter fish

Over the past week, you may have read about the discovery of a fish with a rather unsavory taste for a particularly vulnerable part of the human anatomy.

Ribbons: Terrestrial Nemerteans of Singapore
People with a fascination for marine life would probably have heard of nemerteans, commonly known as ribbon worms.

Most ribbon worms live in marine environments, with a small proportion adapted to freshwater habitats. Just earlier today, I learnt that a small handful of nemertean species have actually managed to colonise the land, and that they can be found in Singapore!

The Chironomids Part II: Millions of Midges

Then the Lord said to Moses, "Get up early in the morning and confront Pharaoh as he goes to the river and say to him, 'This is what the Lord says: Let my people go, so that they may worship me. If you do not let my people go, I will send swarms of flies on you and your officials, on your people and into your houses. The houses of the Egyptians will be full of flies; even the ground will be covered with them. But on that day I will deal differently with the land of Goshen, where my people live; no swarms of flies will be there, so that you will know that I, the Lord, am in this land. I will make a distinction between my people and your people. This sign will occur tomorrow.'" And the Lord did this. Dense swarms of flies poured into Pharaoh's palace and into the houses of his officials; throughout Egypt the land was ruined by the flies.
- Exodus 8: 20-24

In the previous post, I discussed some aspects of the biology and ecology of the Chironomidae, also known as non-biting midges. I briefly mentioned the tendency of many midge species to form huge swarms, which can have negative effects on human communities in the vicinity. This post will look at one such swarming event in Singapore.

Always bring your camera along...
Despite the great distance I have to travel to my workplace every day, one thing I appreciate is that there is a fair bit of wildlife that can be found; if you have been following my tweets, you would notice that I frequently mention random sightings of various wildlife in the area around my workplace; it most definitely helps that we are next to a military training ground with restricted access to civilians, and that there's a large amount of secondary forest and scrub in the immediate vicinity. True, most of my sightings are of creatures commonly seen in parks and gardens, but I still enjoy these encounters.
In recent months, I've tried to cultivate the habit of bringing my camera with me everywhere I go; one never knows when a perfect photographic opportunity might present itself. True, there's always the camera function in my iPhone, but unfortunately, the image quality can never match that of my Panasonic Lumix DMC-FT2.
Unfortunately, I rarely get the chance to capture images of the wildlife I manage to see around the workplace. In many instances, I am either busily occupied with work, or rushing to reach the office on time, and don't have the time to stop and fire off a few shots. Even with time on my side, a point and shoot camera like mine simply isn't suitable for photographing birds from a distance. Even though the plantain squirrels (Callosciurus notatus) are quite tame and spend a lot of time foraging along the road, I just haven't had many opportunities to take out my camera and get close enough before the rodent scurries off.
Today, while packing for work, I was wondering if I should bring my camera along, but for some reason, decided to leave it at home.
Of course, as luck would have it, I was to regret that decision.
I was right outside my workplace, when I noticed something on the small road.
It was a green crested lizard (Bronchocela cristatella), and my best sighting so far; I've seen these lizards from time to time, but they were almost always too far away to be properly photographed.
Of course, I immediately regretted not bringing my camera along, and had to make do with my iPhone.
The lizard was a very cooperative subject, which only made me feel even lousier for not having a proper camera in my hands. For once, I had such a perfect opportunity to get high-quality shots of this species!
Up until the 1980s, this species was very commonly found in various habitats all over Singapore, from forests to parks, gardens and agricultural land. However, with the arrival of the nonnative changeable lizard (Calotes versicolor) from the north, the native green crested lizard appears to have been displaced from most habitats due to competition from its relative. Today, the changeable lizard is the far more common of the two species in open areas, such as in parks, gardens, and scrub, and the green-crested lizard's last stronghold appears to be in the forests, which the changeable lizard avoids.
It's the closest I've ever gotten to a green crested lizard, and the only one that stayed in one spot long enough for me to take a few proper shots.
It almost looks as if it's smiling for the camera here.
Like their relatives the chameleons, many species of agamid lizard are able to change their colour to some degree to suit their mood or their surroundings. However, this green crested lizard wasn't doing a very good job of blending in with the tarmac.
Because it was on a road, I decided to chase it back into the vegetation for its own safety. It promptly skittered to the side of the road, leapt across a drain, and clambered into the bushes.
It was a nice little encounter with a reptile that we don't see very often these days. And I'm now making sure that I bring my camera to work every day.
