Discovery @ Sungei Buloh Wetland Reserve

Fifty Ninth Discovery Posting:

During this week, I was at Sungei Buloh Wetland Reserve (SBWR) almost everyday, from Tuesday (13 May) till today (16 May). Why was I there? It was to guide different groups of students from two different schools, Queensway Secondary and Qihua Primary school.

Anyway, for people who wants to find out more about the reserve, you may visit their website @ http://www.sbwr.org.sg/

In this posting, I'm going to share some of the fauna I saw over these few days.

First 'discovery' is a Malayan water monitor which can be seen if you're lucky (picture below)Discovery Note:
1. Monitors can survive in habitats that wouldn't be able to support other large carnivores as they are cold blooded, that's why they need to bask in the sun.
2. In addition, they eat anything that they can swallow. From tiny insects, to crabs, molluscs, snakes, eggs (of birds and crocodiles) and even other monitor lizards. They even eat rubbish, human faeces, and even dead bodies.

3. The Water Monitor's main hunting technique is to run after prey that it has spotted, rather than stalking and ambushing.
4. Water Monitor Lizards are highly mobile. They can swim, run faster than most of us can run and even climb trees.

5. Like snakes, they have a forked tongue that they stick in and out regularly to "smell" their prey and other tasty titbits.


Second 'discovery' is harder to spot, because usually you will need to listen hard to locate where they are and then look hard to pinpoint their exact location. A cicada (picture below)!
Discovery Note:
1. Cicadas make one of the loudest sounds in the forests.
2. Only males cicadas make the distinctive sound, they make the sound to attract female cicadas to mate with them.

When one walk around the reserve, we advise either silence or to talk very softy if you need. Why? Cause if you make too much noise, you will rouse the third 'discovery' and they will run away. What am i talking about? A Plantain squirrel is what i am talking about(picture below)!
Discovery Note:
1. Plantain squirrels eat mainly fruits and nuts but also snack on insects and other titbits that they come across including bird eggs
2. Plantain squirrels forage mostly in trees and undergrowth and rarely come to the ground.
3. They are active during the day, more so in the morning and evening.
4. They rest in hollow trees and some construct a nest out of leaves and twigs, in tree branches or large bushes.
5. To find out more about the plantain squirrel, click here.

And sometimes if you're really lucky and sharped-eyed, you might spot the fourth 'discovery'. A stork-billed kingfisher (picture below)!
Discovery Note:
1. Stork-billed Kingfishers are the largest Kingfishers found in Singapore.
2. They are rarely sighted because they are shy and less noisy than other Kingfishers.
3. Stork-billed Kingfishers eat mainly fishes, using their large heavy bills to good effect to catch and kill their prey.
4. Want to find out more about them, click here.

And if you are really really very lucky, you will get to see... can you spot it? Let's take a closer look (picture below). A crocodile! Fifth 'discovery'.
Discovery Note:
1. Crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.
2. They feed mostly on vertebrates like fish, reptiles, and mammals, sometimes on invertebrates like mollusks and crustaceans, depending on species.
3. They are an ancient lineage, and are believed to have changed little since the time of the dinosaurs. They are believed to be 200 million years old whereas dinosaurs became extinct 65 million years ago
4. Crocodiles are ambush hunters, waiting for fish or land animals to come close, then rushing out to attack.
5. As cold-blooded predators, they are lethargic, therefore survive long periods without food, and rarely need to actively go hunting.

It was a great experience, going to SBWR for four days straight! Thanks to all students who were in my groups, I hope all of you have had a great time too! =)

Discovery @ KNT & SBWR on 15 Dec 2007

Thirty eighth Discovery posting:

(Entry @ 17 Dec 2007: Correction of ID for both butterflies in this posting. Thanks to Commander for pointing out the mistake => Got the ID for second 'discovery' too, thanks, Ron!)

Just yesterday morning (15 Dec), together with a few members of Semakau and Naked Hermit Crab Guides, we went for a walk along Kranji Nature Trail (KNT) and Sungei Buloh Wetland Reserve (SBWR).

As usual, our speed was a bit slow due to the fact that we were looking out for things along the way and photographing them whenever we spot anything. Anyway, the first 'discovery' of the day are two Dark Brand Bush Brown butterflies if i'm not wrong. (picture below)

Entry @ 17 Dec: The ID for first 'discovery' should be Nigger.
Discovery Note (Updated):
1. This is a common grassland butterfly from the same family as the Dark Brand Bush Brown.

2. The caterpillar of this butterfly is believed to feed on grasses, particularly, Lallang.

And not far away afterwards, i spotted an insect landing on a plant nearby. This is second 'discovery' but i am wondering what this insect is. Anyone can help me with the ID (picture below)?

Entry @ 17 Dec: This insect is the assassin bug.
Discovery Note:
1. Many assassin bugs have been known to bite humans when not handled carefully.
2. For some species the bite is known to be very painful, sometimes causing allergic reactions, and bites can become infected, as with any wound.

And nearby (again), someone spotted this beautiful spider. The ID of this spider might be the Mangrove Big-Jawed spider from the family of Tetragnathidae. Third 'discovery' (picture below).
Discovery Note:
1. When disturbed, it will run away from the web and lie motionless on a leaf or branch nearby.

2. Males are easily identified by their large and prominent jaws, thus their common name.

As we walked into the trail, we spotted a number of St. Andrew Cross Spiders, here's one of them (picture below) and this is fourth 'discovery'.
Discovery Note:
1. These spiders get their name for the way they hold their eight legs in pairs to form an X shape.
2. This X is called the St. Andrew's cross because it is believed that the saint was martyred on a cross of this shape.
3. Besides their standard orb-web, these spiders also build addition white opaque zig zag lines on their webs.

Fifth 'discovery' should be a grasshopper (picture below).
Discovery Note:
1. Those species that make easily heard noises usually do so by rubbing the hind femurs against the forewings or abdomen, or by snapping the wings in flight.


Sixth 'discovery' is a Cabbage White butterfly (picture below). Oh ya, sorry everyone, i kept saying this is White Cabbage =P. Anyway, i was following this butterfly for about 50 meters plus before i got this picture which you see.

Entry @ 17 Dec: ID for sixth 'discovery' should be Psyche.
Discovery Note (Updated):
1. The Psyche is a small and delicate butterlfy.
2. It is relatively common in Singapore.
3. Although it has a weak flight, it can go on flying for long periods of time without making a rest stop, no wonder it took me so long to get one photo of this.

When we reached the mangrove boardwalk of the SBWR, this Malayan Water Monitor Lizard was happily basking in the sun before our voices made it move to another quiet spot (picture below). Sorry.. oh, by the way, seventh 'discovery'.
Discovery Note:
1. Among the largest lizards in the world, Malayan Water Monitors can survive in habitats that wouldn't be able to support other large carnivores.
2. One is because they are cold blooded and thus doesn’t need to use energy to maintain their body temperature.
3. In addition, they eat anything that they can swallow. From tiny insects, to crabs, molluscs, snakes, eggs (of birds and crocodiles) and even other monitor lizards. They even eat rubbish, human faeces, and even dead bodies.
4. The Water Monitor's main hunting technique is to run after prey that it has spotted, rather than stalking and ambushing.
5. Water Monitor Lizards are highly mobile. They can swim, run faster than most of us can run and even climb trees.
6. Like snakes, they have a forked tongue that they stick in and out regularly to "smell" their prey and other tasty titbits.

And along the sides of the boardwalk were some very beautiful flowers from the torch ginger (picture below). Eighth 'discovery'.Discovery Posting:
1. This is also called the Sceptre of the emperor, maybe due to the beautiful flower?
2. The showy pink flowers of a tall perennial look almost too pretty to eat but their flavour is an essential ingredient in some dishes.

3. But its flowers are only used for food before it blooms.
Think rojak.

As we walked on the boardwalk, we spotted an Atlas moth resting on a leave just next to the boardwalk (picture below). Wow! This is my first time seeing a real Atlas moth. Ninth 'discovery'!Discovery Posting:
1. The Atlas Moth has the largest wing surface area of all moths.

2. It is so named because its wing patterns resemble maps.

3. The Atlas Moth's wings have triangular transparent "windows" whose purpose which no one knows yet.

4. The wing tips are hooked and some say resemble a snake's head complete with eye, to scare off predators.

5. Atlas Moths are found only in Southeast Asia and they are common in Singapore, especially from November-January.

The last feature, tenth 'discovery' is a spider which i don't know which species it belongs to. But according to the others, the white thing is its eggs. Interesting! There are many other things which we saw, like jumping spiders which jumped from one camera to another and Siyang's back, many other spiders, misc insects and of course Homo sapiens. =)

Finally, it was really a wonderful outing due to the company and weather. So thanks to everyone and the weather. =)
