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.

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.

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.

otters teasing a croc @ sg buloh - march 2014

Was at SBWR observing a Striated Heron run about a small island chasing bugs near a large snoozing reptile with sharp pointy teeth when there was a commotion towards the right. The heron had also stopped in its tracks and looked to the right as if with some concern that the tranquility of the morning was about to be interrupted. I panned right to see some dark slithery shapes crawling up the slope.

These were two smooth-coated otters out for a morning (it was about 7.45am) swim through the reserve. The basking saltwater crocodile immediately sprang to life doing a 180' in a split micro-second snapping at one of the otters when it came too close to it.  Otters and crocodiles do not share a cordial relationship and frequently gnash teeth at each other.

The two otters, with the smaller one doing most of the work, taunted the crocodile (guesstimate at slightly over 2 m long) repeatedly. Both otters kept 'barking' at the crocodile whilst moving around the crocodile. The larger (quite obviously a male) otter appeared to keep a slightly wider minimum distance from the crocodile as compared to the smaller otter. After getting taunted quite a bit, the crocodile lunged at the closer smaller otter moving about two feet forward in a flash.

Both otters then decided they had had enough and slinkered off to the far side of the island before disappearing under the water submarining (notice the trail of bubbles appearing under the water) further into the northern corner of the pond leaving the crocodile to resume its siesta.

These two otters were first seen about a month before. They have been seen occasionally visiting various seawater and freshwater ponds in the reserve. They seem especially sensitive to human contact and generally stay away from people. This was unlike another lone otter also occasionally seen in the reserve which seemed relatively unbothered when in close proximity to people. There had been a family of 7 otters (2 adults and 5 pups) in the reserve at the start of the year but this family disappeared shortly after the year started. It is possible that the two otters seen in the clip are from that group of five. If so, one might wonder what happened to the rest of that group. The larger male otter had a noticeable wound on the rear right of its tail near its rear right leg. Perhaps that was received from another close encounter with a crocodile.

close encounters of the otteriffic kind @ SBWR 02Jan2014

At about 4.30pm, Jeffrey Teo, a regular visitor to the reserve and an avid photographer, was out and about the SBWR paths when he came across an otter. This otter bounded up the path towards him and JT started taking photos. It soon stopped a few metres away from him and stood on its hind legs calling out. To JT's surprise, another 7 otters came running up the path towards the first otter.
[all photos (c) Jeffrey Teo - Jan 2014]

 The 8 otters started rolling around on the ground scratching themselves against the gravel stones. They did not at all mind the presence of JT as he kept on squeezing all the value out of his camera recording this once in a long-long-time experience. 

 The otters eventually walked right by him and entered the water as a group swimming away. JT made sure he kept still as the otters trundled by him. 

Just the day before, JT had seen (LINK) a lone otter on the seawall barrier which looked like it had an injured rear left leg. The week before he had seen a group of 10 otters playing on a sandbar during a low tide period.

What a fabulous way to start the year!
Jeffrey, thank you once again for sharing!!

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.

3 otters @ SBWR 30Apr2011

Here are the 3 smooth otters going off on their evening hunt (about 5pm). Interesting how the otters form a wall of teeth as they move through the water in close formation. This is a great way to corral fish into the shallows for easy catching. Or to look out for the resident crocodiles submerged in the water!

The otters swam up the main river and crossed the central embankment of smud (sand and mud). From the video, it looks like the first otter crossing the smud was a female with the distinctive nipples visible below its abdomen. The other two otters seemed a little smaller than the first one. There used to be up to 10 otters at one time a few years ago. Where did the rest go?

There have also been otter sightings at various other local shores like Pulau Ketam, Pulau Ubin, Chek Jawa, Changi, Pasir Ris, Woodlands Park and even Pulau Semakau!
