ashy tailorbird @ SBWR 24Jul2011

This little bird was quietly hopping from branch to branch on the cherry tree just past the entry pavilion on the way to the main bridge. Seen at about 7pm. 

This amazing little bird sews its nest on the underside of the large leaves.

crabbed by a lizard @ chek jawa 23July2011

This malayan water monitor was making its way around the mud lobster mounds fringing the mangrove boardwalk. The mud lobster mounds being akin to condominiums housing many different animals also shelters climbing crabs. One particular crab was a tad slow in getting out of the way of the approaching lizard and got caught by the lizard. Looking around to make sure he was not going to be disturbed, the lizard finally chomped down and swallowed the crab whole.

pacific swallows @ Chek Jawa 23July2011

Not sure exactly which species of swallow these belong to. They were seen taking a break on the Chek Jawa House No. 1 jetty railing. They could be either Pacific Swallows or Barn Swallows. Both look very much alike to an armchair birder. However, the Barn variety seems to have a black breast band whereas the pictured birds do not but have a brownish chest instead. They are more likely Pacific Swallows.

oriental pied-hornbill @ Chek Jawa 23July2011

This hornbill showed up at a palm tree close to the Chek Jawa Information Station. It's arrival was announced by a distinctive loud shreeking call. It went about picking ripe palm berries and ate a few before it flew off deeper into the surrounding foliage. Perhaps it had decided that the noisy irritating humans did not deserve an up close encounter with it. Do remember to remain quiet in the reserves and parks so that the animals are not spooked away!

retreating mudskippers @ Chek Jawa 23July2011

These gold-spotted mudskippers in the exposed seagrass lagoon were retreating from the returning tide. Returning tides bring bigger predatory fish and so the mudskippers have to get to their burrows or onto higher ground such as rocks or nearby mangrove trees to get out of harm's way. They were originally in the Halophilla uninervis seagrass patch close to the floating pontoon and made their way about 150 metres towards the mangrove trees towards where the boardwalk path joins the walking trail.

There were a fewbirds like herons around on the seagrass lagoon shallows and these birds would have made a quick meal out of a mudskipper. However, the birds generally avoid the boardwalk area especially where there are people about making it relatively safe for the mudskippers which keep close to the boardwalk. The schooling behaviour of the mudskippers was interesting to watch where the other mudskippers, not wanting to be left behind, had to keep following the others in front. Safety in numbers.

poaching fishermen @ Chek Jawa 23July2011

looks like poaching fishermen are all over the place... this morning at Chek Jawa's Northern shore too.

the two chaps were wearing matching green tops.

white-bellied blind snake @ Ubin 23July2011

Came across roadkill 'probably by bicycle' beside the road close to Ubin town.
It was about 36.5cm long.  


the head ... with very tiny eyes...and a very tiny mouth...

the pointed tail end which may help to serve as an anchor point for this burrowing snake to transfer muscular pressure to its head when burrowing headlong into soil.




the snake was measured at the NParks' Volunteer Hub by Lioe

about 36.5cm when stretched out straight.





in cheap white wine (i.e. alcohol) used as a preservative

note the shiny patches on the outer skin....could this snake be ready to shed its old skin? Normally the upper half should be a nice even black.



the specimen will eventually be passed on to the RMBR.

R.I.P. Great-Billed Heron @ SBWR


The pic above was taken on 18 June2011.
It shows a rare great-billed heron in the hands of its rescuer, albeit a little too late...

A frequent park visitor and an avid photographer, Peter W. had seen the heron struggling in the water almost totally encased in a driftnet near Platform 1 and had alerted the park rangers. However, despite the immediate reaction by the park rangers, it had already drowned by the time human assistance came to it. The bird must have gotten stuck earlier that morning and the rising tide made it a race against time for the hapless bird. By the time the first visitors had made their way to Platform 1, (which is a long way from the entrance and a favourite amongst nature photographers), the bird was already on its last few breaths slowly suffocating with each rising wave.

Poaching fishermen have been a frequent problem at the Sungei Buloh Wetland Reserve. These fishermen are usually based 24x7x365 at the nearby Kranji Reservoir Park where they conduct their wholesale and retail fish business. It is doubted that any of them have a proper AVA or NEA licence.

Many other animals can get caught in these long driftnets which can stretch for over 100m. These range from endangered horsehoe crabs (by the hundreds), birds, otters and even crocodiles.

Read about earlier posts on the illegal fishing :-

and about how the driftnets keep catching animals if they are not removed :

and about the crocodile which had drowned in a driftnet in 2008 :

Read also about Project Driftnet http://projectdriftnet.blogspot.com/ which is a volunteer effort to locate and remove such driftnets which have been abandoned or carelessly discarded by their fishermen owners.

It is hoped that the authorities will take a firm approach to eliminate the use of such nets and other forms of fishing in the areas both around as well as within the now biodiversity-rich wetland reserve. We cannot afford to lose any more of our already endangered animal treasures.



P.s. . The departed bird lies in state at the Raffles Museum of Biodiversity Research.

poaching kayakers @ SBWR 17July2011

These 3 kayakers were out early on Sunday 17July 2011. They entered Sungei Buloh Besar at about 0830 and headed up the river towards the Main Bridge casting their lines.

Later, they were near Platform 1. One of the park rangers called out to them advising them that Reserve area was a 'no fishing' area. Whilst not pretending to be blur, but nevertheless refusing to release the fish already caught, they moved a little further out constantly casting their lines whilst occasionally paddling.

The trio continued to fish a little further away from the shore although well within the mudflat intertidal area. They even cast their lines close to the barge conducting shore restoration works. Later, they moved towards Pulau Buloh, which is still part of the Sungei Buloh Wetland Reserve, and continued fishing.

In the meantime, the resident pair of otters showed up on the sandbank at Platform 1 before swimming up Billabong Buloh (the other way around Pulau Buloh). Fishing lines occasionally get irretrieveably stuck on out of sight objects below the water and fishermen cut the lines sacrificing the hooks and lures. The lures continue to attract fish, birds and possibly even the resident otters and where the exposed sides of the hooks continue to pose an everpresent threat to anything moving past them. Good thing the otters were safe this time.

Recently, on 18 June2011, a great-billed heron was seen splashing for its life after getting stuck in an abandoned driftnet near Platform 1.

Sadly, before the park rangers could rescue it, it drowned.
[pic by Peter W.]

After about an hour, the kayakers reappeared in the waters near Platform 1 constantly casting their lines and occasionally catching fish despite the clear earlier warning given by the park ranger. They eventually headed towards the Kranji Nature Trail.

There was a recent newspaper article about kayak fishing becoming more popular. It is hoped that such kayak fishermen respect the sanctity of the nature reserve and keep well away from it. Help us conserve what little we still have.

A note to others who may think about following these kayakers :-

A quick look at relevant legislation :-

brittlestar @ punggol - July 2011

This 2+2+1 armed bottlebrush brittlestar was quickly moving along the shore. It seemed responsive to light and was generally moving away from the light despite it not having eyes. It must have some other way of detecting the light. Three of it's arms were noticeably shorter than the other two and the brittlestar probably was on the giving end of a meal session of a fish or an octopus. The shorter arms were in a state of regrowth. Amazing for such a tiny animal. Despite this, it showed very little if any signs of being at a disadvantage.

burgundy anemones @ Punggol 01July2011

Here's a clip of a few burgundy anemones (Bunodosoma goanensis) at Punggol.
These anemones were localised around a few specific boulders a little further along the shore. Sporting a deep dark burgundy colour, the average diameter (from tentacle tip-to-tip) was about 6 cm. There were about 20 anemones visible on the boulders in the group. Strangely, we did not see these anemones further along the shore.

painting doubles @ SBWR 26June2011

Tham Pui San was having a painting class at SBWR at the main hide and two of the participants were a pair of twins about 3 (or 4) years old. They were merrily mixing paints like pros and dabbing their art paper, creating swirls and slowly forming their interpretation of the scene before them.

Value of their art? Priceless!

otters @ Chek Jawa 03July2011



(Apologies for the shaky video!. Shot from a distance of about 200metres away.)
Some of the Seagrassing team spotted three large otters at Chek Jawa this morning. These are presumably Smooth-Coated Otters (based on the large size of these animals). They were running along the shore during a low tide from near the elevated boardwalk at the start of the mangroves towards the Northern part of the shore. The otters eventually 'disappeared' around the rear of Chek Jawa towards Johor. The video shows two of the otters trotting along the Northern shore.
