lone injured otter ? @ off Pulau Buloh - 01Jan2014





This lone otter was seen on 01 Jan2014 at about 10am atop the seawall barrier off Platform 1 Sungei Buloh Wetland Reserve by Jeffrey Teo, a regular visitor to the reserve. The period of observation was for about 10 seconds. The otter was harassed by a murder of crows which seemed to be waiting for it to kick the proverbial bucket. It got up and hobbled off the seawall into the water towards Pulau Buloh.

Jeffrey had the previous week seen a family of otters (about 10) at the western edge of Pulau Buloh and was concerned that this otter was by itself surrounded by quite a number of crows. The manner in which the otter got up and hobbled off the seawall barrier also indicated that all was not well with the otter.

From the last photo, it could possibly (?) be that this otter was somehow injured as its rear left leg was pictured rather high as if it did not want to apply pressure to it. It's coat also looks a bit reddish-brown at some spots (but this could be from the otter rubbing itself on the reddish brown soil seen atop the seawall.

If anyone is visiting SBWR over the next few days, please keep a lookout for any injured otter and inform the SBWR staff immediately. Thank you.

Thank you Jeffrey for highlighting this!

sleeping python, frightened squirrel @ sungei buloh - 21Dec2013

Was on the way out from the SBWR when another visitor pointed out a coiled up reticulated python sitting snugly on a limb of a tree beside the main path into the reserve. This was my first time seeing a python in the reserve but i have heard that the reserve has seen this and other pythons before including an assortment of other snakes, both venemous (like the rarely seen King Cobra and more often seen Pit Vipers) as well as non-venomous snakes. The reserve does also have other large reptiles such as the Malayan Water Monitor and the Estuarine Crocodile (Uh, No we do not have Komodo dragons at the reserve). 

This python was being harassed by a determined plantain squirrel and its mate. The squirrels were in a rather excited state compared to the snake which just sat still without flinching a scale. The squirrels kept calling out with loud pips and swatting their tails.  All the excitement was lost on the snake which carried on its slumber oblivious to the concerns of the squirrels.

milky stork buffet @ sungei buloh wetland reserve - Nov 2012

November was a rainy month. It had just started raining when I got to the safety of the shelter on the main bridge. The monotone scene proved uneventful for the most part until the croc showed up close to the main bridge. It did not do much at all except for stay still in the drizzle and occasionally blink its eyes. A while later, a lone milky stork flew onto an uncovered mudbank exposed by the low tide. It soon started looking for food in the shallow water. It dipped the end of its bill into the water and moved its head from side to side whilst walking with its bill slightly ajar ready to shut close the moment some movement was detected within the gap. 
Interestingly, it used its legs to test the surrounding water trying to scare any potential dinner towards its formidable bill. The clip shows the success of this technique where the bird does indeed catch some dinner as a result. After a few bites, it took off towards the Straits of Johor.

scarlet-backed flowerpecker @ sg buloh - 29Jul2012

This little bird with a bright red stripe over the top of its head caught my attention as it tried to deal with a rather large Indian Cherry tree berry at the entrance of the SBWetland Reserve. It looked like it was trying to squeeze the berry in its beak no doubt to extract the pulp. It occasionally tilted its head back to help the extracted pulp flow down its throat.

It was unperturbed by the much larger oriental-pied hornbills a few feet away in the same tree.

grey-headed lapwing @ sg buloh - Nov2011

5th Nov saw a buzz amongst birders when sharp eyes spotted a rare avian visitor the Grey-Headed Lapwing (Vanellus cinereus), to Singapore at the Sungei Buloh Wetland Reserve. Word soon got around and quite a number of birding enthusiasts soon made their way down to Hide 1C. Apparently, it had been some years before this species of lapwing had been seen in Singapore.

Identifying the bird was difficult for a novice with little clue what to look for as all the birds looked...brown. The others birders already there quickly pointed out what to look for and where to look for it.


The bird was resting in an area surrounded by many other shorebirds, plovers, etc. although it was a little edgy occasionally looking up at the sky, probably to keep an eye out for raptors. It made its way towards a log a little way from the shore before taking a bath and then getting back on another nearby log to dry off.

apathetic fishermen II @ Sg Buloh 07May2011

More fishing at Sungei Buloh. Sigh.

And it looks like this is an regular occurrence.

This time there was more than one net...six to be correct! Five were very long drift (or gill) nets [VLD net] and one was a throw or cast net. Three of the VLD nets were being cared for by 2 men on an improvised styrofoam float. Another 2 VLD nets were cared for by ciggy man on kayak (who had made an appearance in an earlier post). Ciggy man's friend joined him later on, also on a kayak. A mysterious 'darkman' (silhouetted against the morning sun) with the cast (or throw) net also was seen crossing the mouth of Sungei Buloh Besar on foot. This chap raised some interesting questions as he did not seem to catch anything despite his casts but he did go on to move some heavy deadwood on the eastbank shore....as if he had been tasked to manage that corner of the shore???.

First the duo on styrofoam with support motorboat. These guys used a motorised boat (SZ10404J) as their base. The motorboat was moored a bit further out in slightly deeper water and the duo moved to it to drop off their collection from each VLG net. From the looks of it, this duo netted a bumper crop of huge catfish and other fish. I wonder how much fish they can eat...surely they would sell off most of this catch. Where do they sell off this catch? (I wonder if AVA licenses them?).

the duo on their improvised floatation device checking on their 3 nets

the duo paddling their improvised floatation device back to homebase, their motorboat.

the duo got off their 'improvised floatation device and onto the mudbank west of Platform 1

They moved along each of their nets picking up fish with ease every few feet of net. An estimate of the distance covered by this group? 200m at least.

Ciggy man on red kayak was merrily checking his nets as well despite him abandoning his fishing on 01 May2011.

He was soon joined by his buddy on blue kayak. Both of them moor their kayaks and conduct their fishery business at Kranji Reservoir Park (rent free).

Then we have Darkman. Mysterious, with no face because of the sihouetting sun, he was observed casting his net a few times across the river mouth. But he had little luck - since there were two gill nets (managed by the Duo and Ciggy man) preventing fish from getting to where Darkman was.

Cast nets are usually much less successful compared to the VLDnets. Darkman made his way across to the eastbank and deposited his fishing gear into a large plastic jerry can cutout. Then he cleared up that isolated corner by moving some deadwood and also carried a long piece of driftwood out of his favourite corner. Was he clearing it up so that he could have a better corner to come back to on another morning?

We need to better protect our Nature Reserves. Fishing with VLDnets just outside of the river mouth will have a detrimental effect on the amount of fish entering the mangroves as the VLD nets effectively are a wall against entry. This may affect the resident otters and crocodiles as there would be a significant reduction on food items over time. These fishermen can be effectively considered resident fishermen as they are around 24x7x365 due to the proximity to their main base at Kranji Reservoir Park. It is probable that they are not licensed at all.

Further, the multiple VLDnets put up in parallel by the different fishermen are a maze for the otters and crocodiles to circumnavigate and there is a very real danger that these animals will get entangled up in the almost invisible nets. Indeed this has already happenned to a hapless crocodile recently. See this link for more info.

No Fishing please @ Kranji Nature Trail - 10Apr2011

Despite the iconic pictogram sign telling all that fishing was not permitted, it seems as if there is a lot of fishing going on along the Kranji Nature Trail.



Singapore's Northern shores harbour some very small stretches of surviving mangroves ecosystems which are the last refuge of many critically endangered flora and fauna. The section of shore seen in the clip is part of a short section where wooden stakes have been driven at intervals into the shore forming an enclosed area for a small mangrove tree nursery.

Abandoned fishnets have often been found along this area adjacent to the Sungei Buloh Wetland Reserve. The long gill nets are usually set up in the shallows over a stretch of 50 meters or longer depending on the length of the net. The wonders of plastic are such that these gill nets are made very long and light and can be bundled up into a small grocery bag ensuring great portability. However, they also last a very long time...perhaps forever.

The floats in the nets ensure that a virtual wall is set up to cover not only the surface of the water but right down in the water to a depth of about 1.2 to 1.5m depth. Depending on where the nets are set up, they could drape over the mudflat floor catching anything within the water column or on the mudflat coming into contact with it. Fish are the obvious target but these nets do also trap other animals unintentionally.

The clip shows two foreign workers arriving by bicycle at the Kranji end of the trail. One of them carries a gillnet bundle onto the shore whilst the other looks for a wooden stake to prop up the net. They walk into the shallows and promptly set up the net. All this takes about 10 minutes and the net is left to the forces of the tides for a few hours or overnight to do their magic in catching fish.

Improperly secured nets can become dislodged and float unrestrained over the mudflat getting caught in fallen trees or even on coral where there is a coraline shore. Such nets are difficult if not impossible to retrieve without cutting up large holes in them rendering them all but useless and so the fishermen leave then where they lie rarely if ever bothering to do the right thing by taking the time to extricate and remove the net. As a consequence, the nets survive in a tangled state and can do so for decades before they may be covered up by sand or mud.

The long nets continue to trap crabs and even birds (and sometimes even the odd crocodile). Many horseshoe crabs are caught in this way. Nets which have gotten loose from their moorings continue to sweep the floor of the shore trapping animals such as the horseshoe crabs. The Northern mudflats are one of the last refuges in Singapore for horseshoe crabs. The mudflats are an important feeding and breeding ground for these ancient creatures. A recent mangrove survey at the nearby Mandai mangroves found horseshoe crab eggs with living embryos in them. This shows how important our Northern mudflats are. This not forgetting that the mudflats are a well known transitory stopover for migrating shore birds. The Sungei Buloh Wetland Reserve which is adjacent to the Kranji Nature Trail does have a brood of resident otters as well and it is forseeable that these otters may get trapped in the nets as well much like the hapless crocodile.

Hopefully, with the ongoing plans for the expansion of the Sungei Buloh Wetland Reserve to cover the Kranji Nature Trail, the incidence of fishing by gill nets will disappear...at least from this small corner of Singapore.

pink-necked green pigeons @ Sg Buloh 10Apr2011

This pair of juvenile pink-necked green pigeons were happily eating their fill at about 1pm on a Singapore Rhododendron bush quite unperturbed by passing human visitors entering or leaving the park. As the bush was fruiting, the birds were gorging themselves almost non-stop.

oriental magpie robin @ Sg Buloh 10Apr2011

The Oriental Magpie Robin is a rare nearly extinct Singapore 'original' song bird. Sungei Buloh Wetland Reserve seems to be one of the few areas where you can see it.  The particular bird was seen at about 4pm near the screen just before Platform 1 and after the Main Hide 1A. It busied itself looking for dried leaves on the floor of the gravel trail ... probably for nesting material.

fishy sungei buloh~10Apr2011

Here is a small selection of fishes seen in the waters around Platform 1 at the Sungei Buloh Wetland Reserve : http://www.sbwr.org.sg/ 


Note the dark mass moving under the water. This is a school of juvenile eel-tailed catfish. A few Needlefish can be seen following the dark mass... possibly waiting for any prey escaping from the dark mass. A closeup of a Needlefish follows. Then a group of what seems like Bromides picking algae from one of the wooden stakes. The leopard-spotted puffer fish ends the clip looking for snails on the stakes. There were also what seemed to be a small school of cardinalfish in the shallows but these were difficult to capture on video.

Otters@Sg.Buloh 15Jan2011

Here's and 8-minute clip on the wild Smooth-Coated Otters of Sungei Buloh Wetlands Reserve.

The 2 otters were spotted swimming near the middle of Sg Buloh Besar and they had stopped briefly around a sunken tree stump before swimming submerged towards the central bridge occasionally coming up for air. Fish in the water scattered as the otters approached and some could be seen jumping out of the water to escape becoming lunch.

The otters swam under the bridge towards what seems to be a frequently used landing point on the near embankment. They then proceeded up the embankment towards the sand box overlooking a freshwater pond near the visitor centre's exhibition hall.

The otters then began a serious session of 'scratch that-itch' which lasted for about 25 mins before settling down for a late morning snooze.

stork billed kingfisher @ SBWR 11Apr2010

stork-billed kingfisher from BeachBum on Vimeo.

Came across this Stork-Billed Kingfisher at the near end of the central bridge at about 12 noon. It had just managed to swoop down from a branch into the water and catch a fish. As if to pose for the onlookers on the bridge (only about 4 metres away), it turned to face the spectators. It started to do quite a bit of gymnastics with it's catch flicking its head from side to side and whacking the fish against the branch as if reassure itself that the fish was well and truly dead. There was a chunk of flesh missing from about a third from the tail. Perhaps the kingfisher had torn that out during the dive and capture process. It spun the fish around in it's beak and swung it against the branch repeatedly. You can just about hear the 'slap'. At times, it looked as if the bird would only end up with the tail end in its beak. Luckily for the bird, the tail end separated and fell to the water below before the bird manouvered the rest of the fish into its beak and swallowed. It took about three minutes to down the fish.


There was quite a bit of background 'noise'.... kids running on the bridge and people chatting - some ignorant of the kingfisher, and a long long camo'd lens with a happy trigger finger and eyeball attached. Hope the others got some good pics.
