the uncommon common kingfisher @ lorong halus Jan2012

Managed to catch a glimpse of this now somewhat more common but previously thought uncommon (in Singapore) Common Kingfisher. Perhaps it is more commonly seen during the migratory season each year.
It flew in to perch just a little above the water and occasionally bobbed its head and looked around. It flew off shortly thereafter.

halus wetlands lechate fishing @ Jan2012

Was at the new Halus Wetlands (it opened less than a year ago in March 2011) and joined quite a few people appreciating the ambience of the wetlands. PUB has done a wonderful job creating the wetlands.

“The Lorong Halus Wetland will provide a new space for members of the public to enjoy not just the tranquility and greenery of the wetland, but also the new habitat that this wetland has created for birds, butterflies, dragonflies and other wildlife,” said Mr Tan Nguan Sen, PUB’s Director of Catchment and Waterways. “We hope that through this site, the public will understand the functions of the wetland, be drawn closer to water and in their own way help to keep the water clean.”

However, there were quite a few people fishing there. In the words of a fisherman, "there are no signs what!".  Well, there were no signs at the pond itself but there was a prohibitory sign at the far corner of the wetlands which did not see many visitors. Some things are beyond everyday comprehension!


There were also people with full loaves of bread...also fishing....i.e. feeding the fish with bread.
Note that the flour in white bread is often bleached using potassium bromate or chlorine dioxide gas. I suppose if it is safe enough for human consumption, then it should be ok for fish...maybe. The fish were certainly enjoying it. And besides, there are no signs restricting the feeding what!
Fish living in treated lechate water could not possibly complain about stuffing themselves with bleached white bread.

Everyone thought that one of the fishermen who was using a bigass artificial lure had finally caught the  whopper he deserved in the treated lechate water pond....only to realise that he had got his line caught on the lotus plants lining the pond. It took some considerable effort but in the end, he managed to yank the line free. Of course there was some collateral damage to the plants ... but well, ... there are no signs what!
(Alas, even if there were signs ...who would stop them?)




I wonder what PUB's position is on fishing at the treated lechate water pond.
Is it allowed? Is it safe? Are the fish OK to eat?
If the fish are not safe to eat, then perhaps PUB should quickly put up signs to alert visitors 
not to fish at the treated lechate water pond.  
P.s. a No-Smoking restriction would also be a good idea as there were already a lot of ciggarette butts lining the pond edge.

You might ask...what is lechate?
Now that you know what lechate is about, would you want to eat any fish from a treated lechate water pond?

caterpillar v ant horde @ rifle range trail - Jan2012

This may be a bit gruesome for some people...you have been warned.


It was a tussle of life and death between the caterpillar and the ant horde. The caterpillar must have been in the canopy overhead and dropped onto the trail where the ants quickly came across it. The frenzy was amazing and the caterpillar's writhing was painful to watch. Such is life in the undergrowth! 


Quotes about ants :
"The foreign policy aim of ants can be summed up as follows: restless aggression, territorial conquest, and genocidal annihilation of neighboring colonies whenever possible. If ants had nuclear weapons, they would probably end the world in a week." - Journey to the Ants - Bert Holldobler & Edward O. Wilson

"... human societies send their young men to war, weaver-ant societies send their old ladies." Bert Holldobler & Edward O. Wilson

"At high tide the fish eat ants; at low tide the ants eat fish." --Thai Proverb

"Ants never sleep." - Ralph Waldo Emerson

"Don't step on ants... they're people too." - a quote from the ANTZ movie

"The constant creeping of ants will wear away the stone." --unknown

... "Like me with the anthill in my backyard. I spent days watching the ants, trying to figure out which ones were good, and which ones were bad, but they all just looked like ants, so I started smiting all of them." "Well that's not --" "I was smiting them with the garden hose, and with lighter fluid, and with the lawnmower, and to be perfectly honest, I think I went a little crazy with the shovel. Those ants could have been praying to me all day, I wouldn't have heard them." "There was nothing they could do about it." "But, I don't think --" "Really, it's the same with us. There's nothing we can do about anything either, so why worry about it? Hey, this is making me feel better." "Well, that's good, but --" "I guess all we can do is live our lives with as much kindness and decency as possible, and try not to dwell on God standing over us with a giant shovel." ... - Dewey and Teacher in 'Day Care' episode from Malcolm in the Middle

two little grebes @ Jan2012

I was told that the Little Grebe is an uncommon bird species in Singapore. It is not normally resident in Singapore but there have been some pairs and young seen over the years in a few select spots. I had no idea that the lil' grebe was a water bird resembling a small duck. I initially mistook an ashy tailorbird in a bush for it but was soon corrected by a puzzled more experienced birder when i described the little grebe I was looking at as 'in the bush'.

The little grebe made occasional pips when communicating with its partner who was at another corner of the pond. This bird was capable of quite a bit of underwater swimming as I lost track of it when it dived in and reappeared some distance away from the dive-in spot. An amazing dive and great escape tactic!
Clip 1 : swimming and diving :-

Clip 2 : Here is a clip of two little grebes going about their daily routine : -

I noticed that the birds seemed to take turns tending to a floating nest in the middle of the pool although the male bird seemed to do more preparing the nest whilst the female occasionally inspected it and sat on it later.

Clip 3 : courtship preliminaries :-
The male bird dives in near the nest and comes up with a bill full of muddy decaying vegetative matter (@0:11) and plonks it down on the nest edge whilst the female is sitting on it. Presumably, this would dry out eventually in the sun forming a better base to nest on. After he plonks down the material on the nest edge, the female bows her head (@0:24) and the male moves towards her rear. He seems to be getting slightly excited...building up courage. He slowly edges himself against the nest (@0:39) whilst the female keeps her head pointing low into the water as if she was targeting some fish in the water.  However, (@1:00) the female decides to get up and re-position herself whilst the male gets noticeably more excited. The male, interrupted, drifts away though not far from the nest.

Clip 4 : copulation :-
After drifting away, the male bird lingers close by until the female again bows her head (@0:59). The male then moves to her rear and against the nest but decides that the moment is not quite right and moves away. At 2:22, the female yawns and begins preening herself. The male follows likewise at 2:39. At about 2:46, both rub the back of their heads against their respective bodies. The female continues preening herself whilst the male floats for a while before yawning again and then rubbing the back of his head again. The female continues with her vigorous preening and plucks out a feather tuft at 3:31. The male floats back at about 4:00. Once he gets close, the female adopts her bowed head position and the male moves towards her rear yet again. At 4:21, the male begins to get excited again.
(!)
At 4:44, the male cannot contain his excitement any longer and jumps up and onto the female. He lowers his rear onto her rear and rubs his rear on her. Meanwhile, the female rhythmically turns her head from side to side. At 5:03, the male extricates himself slowly before quickly jumping off the female. Both then stand looking around for a few seconds before both take to the water in separate directions looking for food and grooming themselves occasionally keeping in touch with singular pips.

golden orb web spider @ bukit brown - Jan2012

I had come across golden orb spider webs at many locations around Singapore before and I had always wondered why these spiders had been called so. I had never noticed anything 'golden' about the previously sighted webs.

I had just visited what was supposed to be the largest graves at the Bukit Brown Cemetary (distinctly visible on Google maps) and was on my way out when someone else in the group spotted a large orb web close to the path.
Click on the map pic above for a larger view. The grave is below the 'X'. Compare the size of the grave to the houses lining Lornie Road. It's gianourmous!

The orb web had 3 layers parallel to each other with one large female orb web spider on the central layer with a smaller red male towards the top of the same layer which the female was on.

The clip was shot at about 11 am and the sunlight hit it from almost directly overhead. The golden appearance of the web was clearly visible. It was then the name of this group of spiders made sense. An 'A-Ha' moment for sure.

A while later, i came across another golden orb spider. This one seemed to be bothered by tiny flies which were harassing it. This one also had a noticeable golden tinge to the web.

stinkhorn fungus @ bukit brown Jan2012

Came across this unusual fungus first at about 10.30 am and then later at about 2.30pm when i went back to the same fungus specimen to see how it had wilted.
Would not have paid it much attention to it and would have passed by without paying more attention to it but was lucky to have Angie Ng around to explain what it was and that piqued my interest enough to get my nose down close to it to smell it. There were numerous tiny flies and a rather large housefly settled on the fungus. One had to get really close to the fungus to be able to get a whiff of the mild stale scent which was attracting the flies.

The fungus is actually below ground and the umbrella-net surrounding a central stalk which is seen is actually the 'flower'. The stale scent attracts the flies and they help to carry the fungal spores away.

When i went back at about 2.30 pm, the central stalk and umbrella net had wilted considerably.

banded woodpecker cooling off @ bukit brown 15Jan2012

I spotted the first Woodpecker just outside of a large hole in a tree. This was just before the tomb with the red-turbaned guards. It flew to an adjacent palm tree whilst another woodpecker (the subject of the video clip) flew in to use the hole in the tree.

After a first woodpecker had abandoned the tree hole, the second one flew up to the tree and inspected the large hole before reversing itself into the hole and disappearing into it. Judging from the splashes, it was having a bath in the water collected in the tree hole. The water could not have been very clean as the bird's feathers looked grimy when it finally came out at about the 3.45 mark.
At the 1.54 mark, you can hear the first woodpecker chasing a third intruding woodpecker away. The 'rapid-fire cackling' was really loud and the chaser bird did not seem bothered with passing close within a few feet of me. It must have been really focused on the intruding woodpecker to have ignored me at such close proximity. It continued chasing the third bird some distance into the surrounding trees.


From a conversation with a friend who is a more experienced birdwatcher, it seems that the cackling had come from a Common Flameback Woodpecker (a.k.a Common Goldenback).

The bathing woodpecker (Banded Woodpecker) saw fit to momentarily stop its bath and looked around to see what the fuss was about. Then, rather nonchalantly, it resumed its bath. The entire bath took about 4 minutes.

Time  : 11.15am, 15 Jan 2012
Place : Bukit Brown Cemetary, the tree at the red-turbaned guarded tomb.

fireworm fished @ labrador 17Jan2012

This bristleworm was 'fished' out by a night fisherman. He had skewered a live bait fish and plonked it down into the water for about 15 minutes afterwhich he decided to check on his lure. What he pulled up did not resemble the bait fish. On closer look, there was a strange worm-like creature enveloping the entire bait fish. The bait fish was about 8 or 9 cm long and the worm was just a little longer than it.
The worm had many many tufts of gold and yellow coloured bristles.
Slowly, the bristleworm or rather 'fireworm' regurgitated the fish which had long stopped moving.
It was later realised that the worm had, during the regurgitation, hooked itself on the hook that was originally on the fish.

Over about 10 minutes, it managed to wriggle the tip of the hook towards its mouth but still had a very obvious problem with the business end of the hook.

Before long, the line was cut and the fireworm was thrown back where it came from. The idea of hook removal was abandoned as the worm would have been impossible to handle and more harm may actually be inflicted on it if a plier was used to remove the hook. 
I hope it manages to extricate the hook out under water. ... if not then the hunter becomes the hunted and something else will probably devour it.

Labrador No-Fishing Fishing Check - Jan2012


Are the no fishing signs at Labrador Park and Nature Reserve being followed?
uh, it's a family affair ... mum & 2 sons right beside the formerly 'no' fishing sign ...
(mum was grumbly after she was politely reminded that it was a 'no-fishing' zone. They were slow to pack up but did so after they were politely reminded of the two signs.
There are two prohibitory signs at the lookout point. 
One on the railing and the other high up the lampost above the circular float.
 The more accessible one on the guardrail had some modification done to it by an anonymous hand ... wonder if the prohibition is obvious to all who may be capable of making the right sense
of it through all the fishing lines. Some reading between the lines required (pun intended). 

No matter ...
... if you can't fish on one side, you can always try the other side... 
it all depends on how far you can throw your line.

 but why bother with moving away when you can stay put 
assured that no one will ever give you a ticket

This guy was at the main promenade (no apparent fishing prohibition) and had what seemed to be the longest and biggest rod and he had an unusual technique which required a lot of space ...wonder if he hit any ships? He did not seem to catch anything though. 
The vid clip shows another fisherman in the background with a green sun hat who narrowly misses another park visitor when he carelessly swings his fishing rod's line in the direction of the passing visitor. Good thing the visitor was keeping a proper lookout and avoided the recoiling line, hook and weight in the nick of time.
That's not the whole story ... is there more?
what is left behind during or after all that fishing?

carelessly disposed packaging


discarded bait bags etc waiting for the wind to blow them into the sea

 bait bits ...  stale flesh

discarded line ... no tripping please

 zipties used to hold the rods to the rail

 more discarded packaging

dead fish ... prize or bait?

 sargassum seaweed gets pulled up by many a fisherman
and who dispose of the seaweed on the seawall and sometimes on the footway

 some fishermen occupy the entire viewing platform and make use of the benches for bait preparation
 rod holders secured to the guardrails ... Some guardrails appear to have been damaged by such abnormal use of them.

 more discarded line

 discarded zipties
 more tape and plastic used to secure the rods left behind after the fishermen pack up and leave

another bait preparation park bench 

a wall display ... hmm......

another wall display ... hmm hmm ...



nil desperandum ... C'est la vie

The prompt response from NParks! Hooray!




Good that NParks is stepping up patrols!

Berlayar Creek - some animal residents - Jan 2012

 Here are some of the animals seen at the Berlayar Creek mangrove :

 a swimming giant mudskipper

 an orb spider tending to its web

(in the open field adjacent to the mangrove)

what can you see in this pic of the huge tree?
The tree is located on the Keppel Golf Course beside the Berlayar Creek mangrove.
Can you see a large nest?
And what about a bird? Two birds?
See if you can spot the two white-bellied sea eagles!
here is one :

some other animals seen but not digitised :
white egrets/herons (not sure which species)
kingfishers (not sure which species)
There were lots of other small birds pip-pipping and chirp-chirping between the trees.

Another rarely seen animal on the mudflats is the horseshoe crab. See if you can spot if when you visit the mangroves during a low tide day.

Berlayar Creek fishing check walkabout 08Jan2012

Sunday morning was bright and sunny with clear skies. The tide was at its highest at about 2.9m @ about 10am. 
 The high tide presented a different view of the mangroves the flooded forest version where the mud was all covered up and lower leaves of the trees lining the mangrove were partially submerged.



 Lots of people were out having a  wonderful morning walk.

The new coastal walk provided for new vistas previously unavailable. 

There was no one seen fishing on the coastal walk this morning. 

However, there were numerous signs that there had been some fishing earlier. 
Bits of prawn shell and flesh strewn on the walkway... 
ciggarette butts strewn about ready to be blown into the water below 
 more ciggy butts and prawn shells

One of the yellow bags contained empty worm casings which can be purchased from bait shops. 

prawn flesh blobs left on the wooden quardrail.
These stink up the immediate area and will give an unobservant visitor a nasty surprise if one touches it. 
 litter left behind by care-less park visitors ... perhaps there needs to be more litter bins?
or should park visitors be expected to exercise their better judgment to hold on to their trash until they get to either end of the coastal walk? The author is for the less-trash-bins approach but this is obviously presenting problems for some less-capable visitors.


 two partially deflated balloons at the surf's edge - not good for sea turtles!

 old driftnet stuck in the Bukit Chermin seawall

someone has already tried to modify the 'no fishing' sign.


Driftnet (see previous post) and overnight fishing via rod & line seems to have already taken root at the coastal walk.
All this in less than a week from its opening.
Ironical that but for the coastal walk, there would not have been the increased threats of driftnet fishing (well, it used to happen before the boardwalk was created and where the fishermen would abandon their long nets to the waves once they felt no further use of an entangled net), increased litter such as ciggarette butts and an assortment of plastic making its way directly off the boardwalk and into the marine and mangrove ecosystems.

Be careful where you step when you are on the coastal walk...watch out for discarded hooks, lines and bait meat etc. If you are a care-less fisherman, well, you own the walk.

On hindsight, perhaps Berlayar Creek and the Bukit Chermin coast should have been left as it was with no public walkway. This would have better protected the biodiversity of the mangrove creek and coastal shore areas. We are certainly not improving the protection which should be accorded to Singapore's only mangrove within 15 minutes of its Central Business District. How many countries can boast of such a mangrove? It deserves better.
