pekan quarry otters @ ubin -17Oct2015

A late afternoon at Ubin's Pekan Quarry proved a good spot for birdwatching. The usual suspects showed up. A grey headed fish eagle, stork-billed kingfisher, two common kingfishers, a dollarbird, barn swallows, bee-eaters, a flock of asian glossy starlings, a white bellied sea-eagle, a couple of brahminy kites, a pair of straw headed bulbuls, two oriental magpie robins, an oriental pied hornbill and lots of grey herons.

Common Kingfisher 
Barn Swallow
Stork-Billed Kingfisher
The endangered Grey Headed Fish Eagle 
Grey Herons loving the first installation of the new floating wetlands at Pekan Quarry.
Grey Heron with Common Kingfisher
Oriental Pied Hornbill
The grey herons were enjoying the new floating wetlands installation. There were 4 to 5 islands of rafts lined with coconut husk fibres mat with some planted vegetation. Some of the herons, presumably juveniles, were actively picking at the reeds. This might be to practise their targeting skills. 

The floating wetlands were also a hit with a group (about five) of visiting otters, (likely smooth-coated otters). Otters have only occasionally been seen at Pekan Quarry and it was great to see them using the newly installed floating wetlands. It also looked like 2 of the otters were spraying the coconut husk matting with their faeces which may be a sign that they are claiming the area as theirs.

Hope the otters like the wetlands enough to make it a permanent home.

dark-sided flycatcher @ pulau ubin - Jan2015

This beautiful little bird flew onto a branch about two metres away and sat there for quite a long moment before flying off to another nearby branch. It did not seem bothered by the presence of a few wandering cotton (and some plastic)-clad bipedalled hominids, a small group of a much larger troubleful species on the planet. Dark-sided flycatchers are a migratory species which visit warmer Singapore during the northern winter months.

Flycatchers, as evident from their names, eat a lot of flies amongst other small insects. They therefore perform a rather useful service getting rid of a variety of small flying insects. No need for insecticides. There was an noticeable lack of mosquitoes within the mangroves but perhaps this is not totally attributable to the prescence of the migratory flycatchers.

Late January seems to be a late stay for this flycatcher as many of its species should be already on their way back up north. It was nevertheless a rare treat for the silly hominids.

thieving eagle vs. hapless great billed heron @ Pulau Ubin - Jan2015

I had just started to observe a great billed heron fishing on a shore when another bird flew into the frame snatching what seems to be a fish from the shore near the heron. The incoming bird was probably a sub-adult fish eagle, perhaps a grey headed but maybe alternatively a white bellied eagle.

The eagle flew off with its catch into the adjacent mangrove forest leaving the heron running after it in protest. Too late. Fishing birds have to make sure that they hold on to their meals lest another grabs it away.

Ubinday 30Nov2014 - birding and otters


Getting an early bumboat ride is always part of the joy of a trip to Pulau Ubin.

The friendly kampung dogs, (many of them originate from the kelongs nearby having been abandoned by their owners),  are ever-ready to greet early visitors. Some dogs adopt visitors for a few hours and tag along during the visit. They gleefully follow you all over the island.


But before tackling Ubin, a must have on a Sunday is the fabulous Lontong at Pak Ali's shop which is situated barely three steps away at the jetty.

3 plates are better than 1... so come with friends! 
(but make sure you order yours first before they do as the Lontong is in great demand)

Today was a day of sharing about what Pulau Ubin has to offer.
As part of the Ubinday event, there was going to be a birdwatching session at the Ubin Pekan Quarry kindly supported by NParks. 
Ubin is an island where secondary forests still cover most of the island and therefore provides for a great stop over for many migrating birds during the Northern winter months from October to March each year. Apart from the migratory birds, Ubin does also provide a home for many resident species, many of which are endangered due to habitat loss. Habitat loss is a real concern as more forested areas get developed on the mainland replaced by displaced granite, steel and glass. 

Getting to the quarry which is just about 5 minutes away from Ubin town is easy. It is a short walk past the Butterfly Hill which is another great place to see local species of butterflies supported by a thriving hill planted with host plants. Each species of butterfly needs a specific host plant to survive. Find out more at the Butterfly Circle blog.

With the heat of the rising sun quickly warming up the morning,  even the resident changeable lizard came out to bask in the sun soaking up the morning vista. What better place to recharge one's cells?

The Ubin quarries used to supply granite for Singapore's early urban expansion and much of the earlier public housing estates were built with Ubin granite. Once the quarries were abandoned, rainwater soon filled up the holes in the ground. From top to bottom, the quarries could be about 100m or more deep. 

Left untouched over time, the surrounding vegetation fluorished providing good perching points for various birds. Resident herons and egrets generally occupy the bare branches at the far ends of the quarry opposite the viewing point. One needs a spotting scope or a pair of binoculars to get see them up close.


The scopes were put to good use and the kids certainly appreciated the larger images of the birds.

Leave them alone with a scope and they are soon pointing at various perches around the quarry. 
A great introduction to birdwatching!
This one was a blue-tailed bee-eater which is a migratory bird seen in Singapore during the October to March period. There was also a smaller bird which was perhaps a flycatcher. The bare tree was about 300m away and the small birds were little blobs.  

There were lots of birds to be seen around the quarry and everyone happy to see the faraway birds up close through the magic of the scopes.

This is a dollarbird. .. a resident of Singapore forests.


Even 'kampung boy' made use of the scope.

NParks had arranged for 3 extra scopes and binoculars to be set up. Staff were also around to help visitors spot and share about the birds seen.
The herons and egrets use the edges of the quarry as a safe roost for the day.
This grey heron had its wings spread out in a V shape to better enable it to cool down since it was perching in sunlight. The birds still need to moderate the rate of heat absorption and they sort of 'gargle' their throats. This is called gular fluttering. The birds flap the membranes in their throat to help with evaporation which helps them cool down. 
Here is the same grey heron cooling itself the gular way...

David helps coach two young birders in the making. 

There was also the spectacular stork-billed kingfisher sitting towards the right of the quarry. This is Singapore's largest kingfisher and is certainly a very colourful bird. 

"What shall i look at next?"

We were lucky to have birding guru Subaraj join us at the quarry. Identifying birds became a whole lot more easier. 

 

Meanwhile,  the birding crowd swelled with the morning sun. 

Even the local media chose to use a scope to get close to the birds. 
(i think a short clip of the footage was used in the evening news)

This little girl had a little difficulty finding the birds but she soon got the hang of it and was soon counting them as fast as she could.

Far away, there was a brahminy kite high on a perch.  This is Singapore's most common bird of prey and is regularly seen near forest edges, open fields and coastal areas. 

We were lucky to have the PM of Singapore come by for a look at the quarry and its native residents. 
Good to have the PM come see rustic Ubin for himself. 
Let's hope Ubin's rusticism is maintained and preserved for future generations.


The species tally (what i saw) was as follows:-
Crow-billed Drongo
Blue-tailed Bee-Eaters
Chinese and Japanese Sparrohhawks, 
Grey-Headed Fish Eagle, 
Green Pigeons, Hill Myna, 
Himalayan and other Swiftlets, 
an assortment of Egrets
Black Bazas
Lesser Coucal
Eastern Marsh Harrier
amongst other birds.

The pick of the morning was the sighting of the Eastern Marsh Harrier. This was a super rare sighting for Ubin. Good that Subaraj was there to identify it.

What a fabulous morning of sightings and sharing!

Thank you to David for for his ever-ready willingness to share about birds (and also butterflies and bees) and his contagious enthusiasm about nature.

Later on, some of us went for a boat tour and we were lucky to see a family of 4 smooth-coated otters swimming free and wild in Ubin's mangroves.
(The kissing noises were made by the boatcaptain in his attempt to engage the otters in squeechy talk. Kissy squeechy noises are not encouraged though. The otters may get the wrong idea!). 

The presence of the family of otters is reassuring. The family was likely made up of a pair of adults with two juveniles. This means that the Ubin mangroves can accommodate the otters. We must ensure that the mangroves are protected or we may see the otters disappear from them. Fishermen should also be careful not to leave their drifters and ghost hooks behind as these do pose a considerable threat to the safety of swimming animals like otters.

Peregrine Falcon eating @ Pulau Ubin - April 2014

Was observing the peregrine falcon atop the communications tower near the Pulau Ubin police station. It seemed bothered by some buzzing bees and kept moving about the railing on the tower. It had been sitting for about 45 minutes before it flew off. I followed it as it flew almost straight about 50 meters before it grabbed another smaller bird in flight. The grab was quick and effective as it moved it's legs back holding the captured bird below. The falcon flew back towards the tower and settled on a platform. Unfortunately, there was no clear view and I had to move to get a better vantage point.

I moved towards the jetty near the shore and saw that a part of the falcon could be seen from that corner.  The falcon was plucking away at the feathers of the smaller bird which looked like a pigeon (or perhaps it was a mynah). Soon the air was filled with feathers. The breeze at the top of the tower carried away the feathers easily and many drifted down or away with the wind.

At about this time, a friend came by with some visitors to Ubin. They were thrilled to see the Falcon and the sight of it plucking away at the feathers of the preyed bird.

The group moved away to the basketball court near the NParks Volunteer hub to get a better viewpoint. Just a bit more of the Falcon could be seen but this was from a slightly longer distance and from an angle which was not much of an improvement. One could still make out the Falcon tearing apart the flesh and swallowing small chunks of meat.

Peregrine falcons are  probably the most widespread birds of prey on the planet. They are known to be more commonly seen in Singapore during the migratory season between the months of October to April. These birds like high perch points and are sometimes seen high up on tall buildings looking down to spot suitable prey. They have even been recorded in Singapore's Central Business District.

A peregrine falcon is usually seen atop this tower at Pulau Ubin during the months of October to April each year coinciding with the migratory season. This may be the same falcon which has been seen for quite a few years. It can sometimes be seen in the trees near the Pekan Quarry as well. As of 1st May 2014, it seems to have disappeared from the tower and may have flown back North.
Let's hope it returns later this year too!

sofa not so good @ Ubin-Jelutong 28Sep2013

Was out for a coastal cleanup along the first part Ubin's Jelutong shore. I had seen two rather unusual items on the second part of the shore (beyond the sluice gates) some weeks ago and wanted to take a closer look since the tide had not been suitable on the earlier occasion.

#1... a weathered yellow leather sofa.

 (you can see sofa #2 in the background - to the right - in the pic above)
 Turned upside down over a small heap of fishnets.
 a closer look at the discarded fishnets below Sofa #1

#2...another weathered yellow leather sofa
within 3 metres of sofa #1 and in a similar upside down position
(What are the odds of this occuring purely at random?)




Where could these sofas have come from?
Who put them there?
The wandering currents?
or a set of hands from nearby?
Where is the nearest human settlement?
Could the nearest human settlement have dumped these sofas on the shore?
If so, why?

P.s. The nearest peopled 'settlements' are from the offshore fishfarms just about 100-150 meters away. And they obviously do not seem to have a trash collection service despite having been where they are for ... decades.!!!!!?

smooth-coated otter @ Ubin-OBS 28Sep2013

Was treated to a rare sighting of a lone adult otter at the OBS-Ubin sandy shore adjacent to the the jetty. It nervously trotted up the beach and started to rub its body over the sand cautiously stopping every few seconds to look around. It was on the shore for just under two minutes and trundled back down into the water before disappearing with a dive.

sunda pygmy woodpeckers @ pekan quarry, Ubin - Feb2013

The former Pekan Quarry is a good spot for birdwatching. The rainwater collected in the quarry provides for a large body of fresh water which would otherwise not be available to the flora and fauna which can be found in the area around the quarry. Freshwater attracts and sustains an incredible diversity of lifeforms which is all interdependant on each other sometimes in the most subtlest of ways.

Sunda Pygmy Woodpeckers are known to be rather common all over Singapore and so it is no surprise that they can also be found on Pulau Ubin. They can also be found right in the city (see Link) if you take the trouble to look at the small birds flying between trees in the city.

These birds at the Pekan Quarry were busy looking for food on some bamboo at the edge of the quarry. There were insects in the bamboo and the birds did a good job of extracting the insects with their bills and tongue.

rufous woodpeckers @ chek jawa mangroves - Feb2013

February 2013 was a very wet month with some days having intermittent heavy rain from morning till the afternoon. The penultimate level of the Jejawi tower provided some shade from the light rain and also a great vantage point to look over the surrounding mangroves and forest. It's rare to see so much green in Singapore. 

During the brief lulls in the intermittent rain, some of the birds showed themselves. There were the oriental-pied hornbills, straw-headed bulbuls(quite a few), olive-backed bulbuls, magpie robins, black-naped orioles, pink-necked green pigeons, brown-throated sunbirds, crimson sunbirds, a white-bellied sea eagle, and a great-billed heron amongst many other birds.

A red streak flew across the scene and settled on a nearby tree. It was a rufous woodpecker. This was my third time seeing a rufous woodpecker. The first was also on Pulau Ubin although at the Jelutong mangroves which is on the Southern side of Ubin. The second was at the Berlayar mangroves. 

The bird was soon joined by another rufous woodpecker for a brief moment before the latter flew off to another nearby tree. Rufous woodpeckers are rarely seen resident birds. Habitat loss seems to be the main reason why these birds are not seen more regularly. We need to ensure that our already rare coastal mangroves and forests are conserved.

hermit crab house swapping @ Ubin - Dec2012


The clip shows two blue-striped hermit crabs in one of the mangrove pools (former prawn pond).
These crabs were both in Rodong snail shells. I was alerted to some house-swapping action by a knocking sound. One crab was tapping or knocking onto the other shell which was occupied by the other crab.



The loser was cajoled out of its shell by the aggressor and it ran out beyond the reach of the aggressor who promptly assessed the now empty shell. Finding it suitable, it climbed into the 'new' shell leaving its own free for the loser to lay claim to it.  The victor's former shell now empty was free for the loser to occupy which it did without much hesitation. Any protection was better than none and hermit crabs cannot afford to be 'naked' i.e. without a hard shell because their bodies are naturally unprotected and soft. 

With both crabs swapping shells, they quickly parted ways. Perhaps they may meet again on the other side of the mangrove pool ... and another battle may present itself. What a great way to recycle one's home!

the uncommon common kingfisher @ ubin - Dec2012


The Ubin mangroves seems to be a good spot for kingfishers.  At least 4 types can be seen with some patience (or good luck). The Common Kingfisher is nowhere near as common in Singapore as it is in Europe. It is rarely seen and is rather skittish preferring to fly off at first glimpse of the all too common mostly upright apes.

The birds seen in these clips may be the same bird or two or three birds which cohabit in one particular part of the mangroves. There were also stork-billed kingfishers, collared kingfishers, and even the rare black-capped kingfisher.

One particular characteristic of the tiny sparrow-like common kingfisher is its ability to hover at a spot. Despite their small size, they can fly past at an astonishingly fast speed...such that all you see most times is a blue blur.

The clips show the common kingfisher flying in and out from perches near the water surface and even momentarily hovering to target prey fish in the water. (Segments showing the kingfisher in action have been slowed down to 12.5% normal speed but even this seems too slow to appreciate the high speeds displayed by the dimunitive speedster).

peregrine falcon @ ubin - Dec2012

Last year, the telecommunications tower at Ubin village had a falcon on it at the end of October. This year, it seems to have been only seen first in early December. It sat actively looking around high atop the telecommunications tower. It did not seem to be bothered when a circling white-bellied sea eagle and later also a brahminy kite passed close by.
Singapore in within a long list of countries which is supposed to have resident peregrine falcons. However, it seems that the best time to see peregrine falcons is during the Oct to April period. This coincides with the migratory season for Northern hemisphere's winter.
It is thought that the telecommunications tower falcon is a migratory one as it is not seen for pretty much the rest of the year outside the Oct to April period.

Habitat loss due to human development continues to be a threat for seeing these falcons 'in the wild'. However, these falcons are frequently seen amongst high-rise buildings amongst a concrete jungle. They seem to thrive even in high-rise cities.

An 'unwelcome' net @ Ubin - Sept 2012

Sat 8th Sept was the first day for the annual International Coastal Cleanup Singapore event. 
As volunteers headed out all over Singapore's coastline and mangroves, some were on Ubin to do their bit for Ubin's shores as well. 

It was a great morning to go to Ubin. Clear skies and fresh air.

Alas, just off the jetty, there was a familiar sight. Someone had recently dumped a net, no, two fishnets on the rocks near the jetty. Perhaps the owners had known that a cleanup of the beach area was scheduled for the 8th. 

Disposal of unwanted nets by abandoning them on the coast is not new to Ubin. This has been going on for years, if not decades. Ubin's shores especially the Southern shore facing mainland Singapore have been used as a dumping ground for unwanted fishing nets used by sampan fishermen as well as fishfarm or 'kelong' nets. There are many many such nets lining Ubin's Southern coast. There are even some places on the Southern coast where fishfarms have abandoned large pontoon sections on the beach...left to the waves and time.

rufous woodpecker @ ubin - Sept2012

After a rather long hike through a forested area and temporarily dectivating a boar trap, a walk along Ubin's Jelutong mangroves was a welcome relief. These reddish-brown birds caught our attention as they flew through the mangrove trees. It was my first time seeing these Rufous Woodpeckers and there were four of them. I did not see all four of them but PH said that he counted four. They were about for about a minute before they flew further into the mangrove thicket. Rufous woodpeckers are common on the Indian subcontinent but they are not so common in Singapore.

yellow-vented bulbul @ ketam quarry @ ubin - may2012

Saw some rustling in the trees and it turned out to be a bird feeding. It was a yellow-vented bulbul which is a very common bird in Singapore. Not sure exactly what kind of tree it was but perhaps it was a  type of ficus???.

Location : at the Ketam Quarry hilltop 
Time : about 2.45 pm

Project Driftnet Singapore - Ubin 18Dec2011

Here's a short clip showing some parts of the morning's Project Driftnet effort.
Care-less fishing practices, unsatisfactory fish-farming protocols and a lack of adequate regulatory supervision cause long-term problems for biodiversity on the shores where the illegal dumping of non-biodegradeable fish nets persist.

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.
