On the way to One Degree 15, I heard a Large-tailed Nightjar and a Sunda Scops-owl on Sentosa.

Out on sea, we got Swinhoe's Storm-petrels heading east, and Bridled Terns heading west.

As well as the usual cast of terns, like this Aleutian Tern,


and this Great Crested Tern.


The buoys, like this yellow buoy, is a good place to look for perched terns.

Singapore Strait 29Apr17

From JS
On 29 April 2017, we joined the pelagic trip (2x boats) organised by See Toh and Francis. Straits of Singapore is probably one of the last few frontiers for birdwatching in Singapore. There are still a lot of knowledge to discover concerning the movement of seabirds through this part of the world. With a bit of fortuity, a vagrant may appear - which is the case in other waters of the world. For birdwatchers seeking an additional tick for their Singapore list, the Straits of Singapore is the place to explore.

Setting off at 7am from Sister's islands where we had just cleared customs, we headed eastwards towards Horsburgh Lighthouse, our key destination for the day. For the first one and a half hour, we saw nothing. The weather was not favorable with dark clouds before us. Our first bird was a pair of Little Terns. Following which, we encountered an Arctic Skua in the distant. Thereafter, it was just Bridled Terns and Short-Tailed Shearwaters capturing our attention. To think that a couple of years ago, the latter was not even recorded and our count has exceeded 10 by the time we had reached Horsburgh Lighthouse!!!


Bridled Terns


Short-tailed Shearwaters

At Horsburgh Lighthouse, I was honored to finally record the Black-Nest Swiftlet for my Singapore list. To do so, I had to spot the birds on the black nest built below the window ledge of the buildings on the outcrop. Tough work!

Another interesting sighting at the lighthouse was a pod of three Indo-pacific Humpback Dolphins including one calf. To demonstrate our delight for the sighting, we actually spent additionally time circling the outcrop two times in search of them. Alas, they did not show again...


Indo-pacific Humpback Dolphin

Heading back, we stayed close to the Indonesian side of the International waters. This rewarded us with further sightings of Short-Tailed Shearwaters, Bridled Terns, three White-Winged Terns (including one individual moulting to breeding plumage) and an Aleutian Tern in breeding plumage. Great sightings, especially the birds in breeding plumages.


White-winged Tern


Aleutian Tern

Hoping to find something different, we checked the yellow buoys off the coastline of Indonesia and found resting Lesser Crested Terns, a new bird for the trip.

Just as we were leaving the last buoy to head back to Singapore, we saw an all-dark bird gliding at the surface of the waters. The flight of the bird resembled that of the Shearwaters. Thus, I was too quick to identify it as just another "Short-Tailed Shearwater". Thankfully, See Toh was quick to point out something unusual about the bird - it had pale upperwing coverts. This was no shearwater, it was a passing Bulwer's Petrel!!! Out of our excitement, we actually made a U-turn and attempted to look for the bird. The bird was probably long gone by then but we just wanted so much to re-find it. The significance of the sighting was simply the bird has yet to be recorded in our Singapore checklist. Any sighting of the species could mean a step closer to its inclusion...


Bulwer's Petrel

After seeing 10 species of seabirds, including a potentially new species for the Singapore checklist, all the participants were in fine spirit. All of us would like the birds to come closer to our boats but as with any pelagic outings, nothing is certain. The potential of finding new birds or the risk of going home empty handed makes pelagic outings so interesting. With eagerness, we await our next pelagic adventure...

  1. Bulwer's Petrel (Bulweria bulwerii) 1
  2. Short-tailed Shearwater (Ardenna tenuirostris) 27
  3. Grey Heron (Ardea cinerea) 1
  4. Brahminy Kite (Haliastur indus) 1

Batu Gajah, Sawah Ring, Sg Balang, Parit Jawa, Malacca Strait 22-23Sep12

From KH

Con, Danny and I joined Ang and his friends for birding at the padi fields and Malacca Strait.

We spent the first day in the padi fields and what a hot day it was. As the padi fields were pretty dry, there were not many waders, although we did find Wood Sandpipers, Common Sandpipers, Pacific Golden Plovers and Red-wattled Lapwings. Herons (Purple and Little), egrets (Cattle, Little, Intermediate and Great) and bitterns (Cinnamon and Yellow) were common in the fields. Other birds of note were a Watercock, Oriental Reed Warblers and Grey Wagtails. In one of the rivers, there were Common Moorhens, Purple Swamphens and Lesser Whistling Ducks.

At Sungei Balang, there were many grassland birds - munias (White-rumped, White-headed and Scaly-breasted), Baya Weavers, Zitting Cisticolas and a Paddyfield Pipit. We managed to locate two boxes with Barn Owls in them. As it was still too early for raptors, we only saw Black-winged and Brahminy Kites.

The second day, by contrast, was really wet! It rained on and off the whole morning. While having breakfast, a pair of Oriental Pied Hornbills on antenna were a welcoming sight. After breakfast, we took a boat trip from Parit Jawa to the Malacca Strait and spent about 4 hours out in the sea (around 9 am to 1 pm).

Lesser Adjutants - the iconic birds of Parit Jawa.

Lesser Adjutants

First, we encounter the commoner terns, like Little Terns, White-winged Terns and Great Crested Terns pretty near the coast and at the kelongs.

White-winged Tern

Great Crested Tern

As we went further out, we started seeing Bridled Terns heading south. We counted about 100 birds by the end of the boat trip.

Bridled Tern

The first star bird of the trip appeared around 9:45 am. It was an Aleutian Tern - a lifer for the Malaysian birders. The bird can be told apart from others by the white forehead, thin black bill, thin black trailing edge on the secondaries, white leading edge and pale rump.

Aleutian Tern

Before long, we encountered our first Swinhoe's Storm Petrel - another lifer for the Malaysian birders. We would see another two later. Finally, we spotted a pod of dolphins on the way back.

The final count of pelagic birds:
Swinhoe's Storm Petrel 3
Aleutian Tern 1
Common Tern 2
Bridled Tern ~100
Lesser Crested Tern 1
Great Crested Tern ~50
White-winged Tern ~10
Little Tern ~5

And water birds at Parit Jawa:
Lesser Adjutant 15
Grey Heron 5
Little Heron 3
Little Egret 5
Greater Sand Plover 1
Lesser Sand Plover >20
Common Greenshank 1
Common Redshank >20
Common Sandpiper 3
Terek Sandpiper >20
Whimbrel 1
Black-tailed Godwit 2

Sungei Balang, Parit Jawa, Malacca Strait, Muar 25-27Nov11

From JS

On 27th Nov, Con, my father (Danny) and I went for a short half-day (exactly 3h) pelagic along the Malacca Straits. The highlights being seeing a lot of feeding Aleutian Terns (probably the most common tern along the Malacca Straits at this point of time) and a lone passing Swinhoe's Storm Petrel - unfortunately, no photos for the latter. Additionally, we had a very close encounter with a large pod of >10 dolphins, including a jumpy baby.

Briefly, we started from the fishing village of Parit Jawa and headed out to the International Waters. Based on the few sighting records off Malacca Straits (Kedah) and Singapore Straits for the month of November, we were expecting a "dry" session and according to the local fishermen, there was a real chance of a "bird-less" outing. The first hour was literally (sea)bird-less, minus the few barn and pacific swallows. Fortunately, we had some dolphins as company for the first part of the second hour. After reaching close to the mid-point of the channel, we had our first sighting of a seabird, an Aleutian Tern. This followed by more sightings of Aleutian Terns before culminating with a rough count of 7 flying birds in a 100m radius of our boat (Poor visibility due to haze and impending storm), excluding 3 on driftwood (not rubbish!). On the way back, I spotted a lone Swinhoe's Storm Petrel heading in the direction of the Indian Ocean. Rounding up the trip, we saw a pair of Common Terns resting on a drift wood. Although the pelagic trip was done on an ad hoc basis, seeing some of our regional migrants appearing along the Malacca Straits may be newsworthy itself.

List of Seabirds seen along the Malacca Straits (MS) and Parit Jawa (PJ):
1) Little Tern (>10 at PJ and MS)
2) White-Winged Tern (>20 at PJ and MS)
3) Whiskered Tern (1 adult was seen at PJ)
4) Great Crested Tern (2 at MS)
5) Aleutian Tern (>10 at MS)
6) Swinhoe's Storm Petrel (1 all-dark petrel-like bird was seen and suggested to be of this species because of flight (close to the water surface with slight changes in direction, typical of passing Swinhoe's Storm Petrels along the Singapore Straits), darkish appearance, pigeon-headed and paler upperwing coverts.)
7) Common Tern (2 at MS)

Other notable sightings: Indopacific Bottlenose Dolphins (2 pods of >10 and >5 respectively. Both pods were seen heading towards Singapore Straits with one pod spending some time at the fishermen's net.)

Singapore Strait 20Aug11

From Colin

The NParks supported monthly Singapore Straits pelagic survey went out again on Saturday and this time we made it all the way to Horsburgh Lighthouse. Highlights were large numbers of Bridled Terns, an adult Long-tailed Jaeger, two different Lesser Frigatebirds and at least one 1st summer Aleutian Tern (which may be a previously undocumented plumage). Thanks as ever to Con Foley for his photos of all the best birds:

Our route and the localities of the above are posted on this map link.

In terms of the Bridled Terns there were 80-100 on and around the rocks and buildings of Horsburgh Lighthouse including many birds of the year indicating evidence of successful breeding. There was then a separate feeding flock of about 40 birds comprising largely of young individuals foraging on flotsam along with the Aleutian and 2-3 Common Terns about 18 km west of Horsburgh. In addition throughout the day there were large numbers of predominantly adult birds passing east through the Straits with a final count of 148 birds involved in this movement. We had a day total of six tern species, and that didn't include Lesser Crested!
