marsh harrier at rest @ sg balang - Dec 2014

It was about 6.15pm at Sungei Balang and the sky was turning slightly dark due to ominous rain clouds on the edge of the ricefields. It had rained heavy for about an hour earlier in the afternoon and the everything was still a bit wet. Only about 10% of the fields were brown having been harvested sometime earlier and left unplanted. The remaining 90% were very green and flooded. Quite a few of the resident raptors such as brahminy kites and black-winged (or -shouldered) kites had been active flying about looking for dinner. The menu would have contained frogs and snakes mostly. The rats would likely only appear after the flooded fields have been drained and the padi harvested.

On the way out through one of the paths, a short frond bore an unmistakeable form. At first glance through the warp of the windscreen, I thought it was a juvenile brahminy kite. Slowly approaching closer, this was realised to be a marsh harrier. After taking some initial record shots, moving the car closer slowly proved a good ploy. The car was about 5 metres away and the engine switched off. The cover of the car provided a good vantage point for the camera to be carefully extended out and rested on the sideview mirror casing angled appropriately at the bird's direction. The bird eventually flew off showing a characteristic white band on its rump. 

I'm guessing this was a juvenile female eastern marsh harrier. It also had a dash of white at the top rear of its head which is partially visible at certain parts of the clip. A most beautiful bird. Glad it took some time out to share its beauty.

(There is a residual hum in the background and that is presumably from the motorised sprayer in use by one of the farmhands about a hundred metres away.)

barracuda, fish eagle and lots of fish @ SBWR - Dec2014

Lower tides over a mudflat makes for an interesting phenomenon. The smaller fish accumulate above the shallow mudflats corralled by predatory fish such as barracuda. As the smaller prey fish school themselves into tighter shoals, space becomes a premium and when you are chased by a hungry barracuda with a full set of very sharp teeth, the only way is up. The prey fish get into such a tight grouping that the barracuda literally explode into the group and out of the water in an effort to get dinner. That was already unexpected but then the forward section of the group began to jump in a continuous chain resulting in another unexpected sight. What was thereafter another unexpected consequence was to see one of the area's resident white-bellied sea eagles (or 'fish' eagles as they are also called) swoop down in an excited attempt to grab some jumping fish. The eagle was unfortunately unsuccessful despite its persistent fly-bys. It was a pity that an osprey which had been sitting on a kelong stump close by had flown off a few minutes earlier. It would have been interesting to see if the osprey would have been better at catching jumping fish than the fish eagle. Ospreys of course don't mind getting wet when going after fish.

Note however that SBWR is a Nature Reserve and has a 'No Fishing' rule...unless of course you are a fish-eating raptor, watersnake or a crocodile. Fishermen (even those on kayaks) will get paid a visit from the NParks and also the Police Coast Guard patrols. Bring a pair of binoculars instead and enjoy the show.

barracuda cant jump @ SBWR - Dec 2014

Barracuda can jump and they can jump high. The clip is being played back at 25% normal speed. The intention was to capture the shoal of smaller nasi lemak fish jumping and it was not expected that their predators would also be seen displaying their aerial acrobatics exploding out of the water after their prey fish. 

What a magnificent show of natural behaviour!


Note : SBWR is a Nature Reserve and a 'No-Fishing' zone unless you are a barracuda, raptor, water snake or ... a crocodile and there are loads of these helping to keep the waters of the reserve in check.
P.s. the penalty for fishing within a nature reserve is a hefty fine. 
(It's not worth the fishing actually. Bring a pair of binoculars instead.)

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.

shield bugs on fish-tailed palm @ SBWR - Nov 2014

These 20 or so shield bugs were taking an afternoon siesta below a fish-tailed palm leaf. Not much movement except for one or two of them. There was one which was more red than the others which seemed metallic. The palm was itself very close to the mangroves and it was likely that these bugs had transferred themselves from further within the mangroves to the palm.

osprey & fish @ SBWR - Nov2014

Ospreys are impressive fishing birds. Sungei Buloh Wetland Reserve has seen a return of the migratory ospreys. This one sits atop a favourite perch visible from the quiet Mangrove Boardwalk section.

It had been sitting quietly the water from the bare branches for about half an hour towards the late evening. At about 6.30pm, it flew off returning about half a minute later with a fish in its talons.

The fish was very much alive as it thrashed about in the sure grip of the osprey. The osprey had to spread its wings each time the fish thrashed about to steady itself on the bare branch. This went on for a few minutes with the osprey trying to sneak a bite on the fish.

Finally after about 5 minutes, the fish stopped moving and the bird settled down to its dinner.

Find out more about this amazing bird and the Sungei Buloh Wetland Reserve.
