Batam pelagic 05Oct24

From KH

Danny, JS and I went on a pelagic trip at Batam again. This time with James Hogg.

Setting off from Harbour Front, in Singapore waters, we logged 2 Bridled Terns, 2 Great Crested Terns, 5 Little Terns and 4 Swinhoe's Storm-Petrels. Good start for pelagic.

In Indonesian waters off Batam, we got a good haul of 249 Swinhoe's Storm-Petrels, as well as 1 Aleutian Tern, 2 Gull-billed Terns, 2 Great Crested Terns, 4 Little Terns and 30 Bridled Terns.


Back in Singapore waters, 2 Aleutian Terns, 2 Great Crested Terns and 20 Little Terns.

The pelagic won't be complete at this time of the year without Swinhoe's Storm-petrels.

Singapore Strait 06May17

From JS
Facing stormy weather from the west, we headed out into the Straits of Singapore. Unlike last Saturday's outing, we had a mission to find a Swinhoe's Storm-petrel for Subaraj's client. Of course, the mission is only binding to Subaraj. We were just interested to find any birds that are passing through our waters.

We had a great start when Frank spotted an all-dark bird flying in the distance. Photos captured revealed a Short-tailed/Sooty Shearwater.


Next, we saw feeding Little Terns everywhere we go.

Just when things was starting to get quiet, we spotted four dark blobs on the water aka sitting ducks. It must a relief for Subaraj when the birds turned out to be Swinhoe's Storm-petrels. Great! A new tick for the diehard birder. Honestly, Singapore's waters are really good for this species - much to the boredom of the residents... Nevertheless, we have learnt to find joy in the subtle behaviors and one individual even went to the extent of feeding right before our eyes. It was tiptoeing on the water as it repeatedly bowed its head to scavenge floating "food". Alas, its "food" was the plastic waste strewn all over the waters. *:(( crying


Besides the four storm-petrels, we encountered a further dozen more and another single Short-tailed Shearwater.


That was the end of the five minutes of excitement. We floated around for another two hours without any notable sightings. Again, when things had gotten too quiet, eight terns flew passed our boat, heading westwards. Frank got a bit skeptical about their preliminary identity, Bridled Terns. Thanks to his skepticism, we found two greyer individuals among the eight and they were Common Terns of the longipennis race in breeding plumage, sporting an all-black cap and white tail streamers. Lovely!


Since it was past noon, we decided to head home. Facing St John's island, we spotted another all-dark bird, gliding above the surface of the water. The flight was rather slow with more gliding than flapping. My preliminary id of the bird was Short-Tailed Shearwater while Frank was leaning towards a Storm-Petrel. We were both wrong. It was none other than the area's third sighting of the Bulwer's Petrel.


The appearance of the Bulwer's Petrel brought life to the boat. Yes, the bird has been seen a week ago. But, who would believe that a pelagic bird would linger for a week? The id of the bird was cast in stone and the only questions in our heads were "was it in Singapore's waters?" and "are Bulwer's Petrels passing through our waters regularly?" Such trivial questions make the aftermath of seeing a bird more fun. The experience lingers longer when there is some reflection. Amazingly, the Bulwer's Petrel, a bird not recorded in our last couple of dozens of boat trips, was to be our last bird of this memorable trip. What a great closure!

After the boat trip, Danny, JS and I went to Imbiah to look for the Hwamei, but none were found...

There were also not many birds, but we did see Coconut Lorikeet, bulbuls (Olive-winged, Yellow-vented) and other common birds.

Singapore Strait 5May12

From Colin

We took the boat out Sat an east along the north shore of Batam on Sat morning returning via Changi and west along port limits. It was initially rather slow with small numbers of terns, a handful of Swinhoe's Storm Petrels and some distant all dark shearwaters that were too far and moved too fast to be identified. Then on the return, along the edge of port limits east of Kusu Island we hit a passage of storm petrels and recorded 91 birds moving rapidly east in the space of about 15 mins.

Final totals for the days were as follows:

Swinhoe's Storm Petrel 96 (minimum) - a record spring count?
Shearwater sp (all dark) 4
Lesser Crested Tern 30
Black-naped Tern 8
Bridled Tern 2
Little Tern 2

The other highlight was a group of 5+ Bottle-nosed Dolphins north of western Batam.

Singapore Strait 15Oct11

From Con

From Colin

Although it was quieter than September and we didn't get quite so far out we recorded the following:

Aleutian Tern – min. 7 (all winter plumage)
Swinhoe’s Storm Petrel - min. 9 (no noticeable movement, mostly disturbed off the sea in pairs)
Bridled Tern - 73 all moving east
Crested (Swift) Tern – min. 44, with a noticeable movement to the east
Lesser Crested Tern - 6
Little Tern – 1
Long-tailed Jaeger (Skua) – 2 ( harassing the terns off the north eastern end of Batam)

Finally we also returned via the Grey Heron colony at Pulau Bukom, where there were about 16 active nests and a nearby white phased Reef Egret, plus a Great-billed Heron on Pulau Jong on the way past.

Route is at the below link.

We were out again on the monthly NParks supported seabird survey boat again on Saturday (Sept 17th) and migration was in full swing. The most numerous birds were Bridled Tern with a total of 597 all moving east, however in second place were Swinhoe's Storm-petrel with a total of 510 almost all moving west. The Bridled were moving throughout the day and all across the channel, but almost all the Swinhoe's were seen between 07.45am and 10.45am along the Indonesian side of the shipping lane north of Batam. Despite these vast (record?) numbers other birds were in short supply with about 20 Aleutian Terns (mostly moulting adults) being the only other notable sightings. The other interesting sighting was watching a Swinhoe's Storm-petrel sat on the sea picking at a small dead fish floating on the surface.
