croc on the path @ SBWR 08May2011

Was walking along one of the quieter paths with my boots making quite a mini-ruckus on the gravel eventhough I was trying my best not to when i looked up to see a tail disappearing off the path about 5 mteres ahead into the adjacent foliage. Instantly it occurred to me that the tail was way too broad and speckled to belong to a monitor lizard. It had to be a crocodile! I could not help but feel both surprised and shocked at the same time. Cautiously, i moved forward towards where the tail disappeared whilst looking out for the croc. It was down the embankment and near the water ready to plunge in if needed. The shade of the overhanging trees made it a bit difficult to spot the croc. One had to be looking for a croc to see it. It's speckled hide also camouflaged it very well. It did not seem bothered by a human with much less sharp teeth than it did. For good measure, it left its mouth open showing off its many many sharp teeth.

The croc must have been sunning itself soaking up the morning sun when it heard me coming. It pays to be attentive when in Nature Reserves ... and quiet.

otter makantime I @ SBWR 30Apr2011

This smooth otter was seen in the gallery pool at the SBWR visitor centre carrying what looked like a fish leftovers. It was a bony fish and it must have been rather large. The otter moved with it to the side where it was shallow enough for it to stand on its hind feet (and probably using its tail also as a third leg). It then proceeded to really bite into the bony fish carcass crunching into the bone.

Unfortunately, it looks as if it got a bone stuck in its teeth and it dropped the carcass to try to use its claws to dislodge the bone. Whilst it did so, it was distracted away from the approaching monitor lizards who could obviously smell the fish carcass. It soon dislodged whatever was causing it discomfort, looked around the murky green water for the fish and grabbed it before any lizard got to it. It then swam away with its catch to another part of the pool.

hunting herons @ SBWR 08May2011

A compilation of short clips of a few grey herons stalking and hunting fish (or prawns) for food. There is a segment of a juvenile grey heron having speared a small catfish and then dropping the catfish onto the mud in order to re-position itself for another deadly and forceful impaling strike. The bird then deftly beaks the fish in order to swallow it whole. And after that, it washes its beak in a nearby pool. The slow-mo replay @12.5% is still not quite slow enough to clearly capture the speed at which the stalking herons strike at their prey. Faster than a blink!

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 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.

plantain squirrel @ SBWR 30Apr2011

These squirrels are commonly found all over Singapore. This particular one was at the SBWR Mangrove Boardwalk at about 1pm actively biting into and eating the bark of what seems to be a Sea Hibiscus bush. Maybe it was looking for bugs below the bark but it sure seemed to bite deep into the branches.
