23 - 25 March 2012: Kapar power station. 6. Small stuff

These are mostly pics taken on the smaller ashpond roost. For the last few years, this was the main roost, but now that the pond is dry, it's mainly used by sand plovers and stints.


































In the late afternoon sun, the Greater Sand Plovers in breeding plumage looked stunning.

































At this time of year, the different moult timing of Greater and Lesser provide an additional clue to identification. On the whole, Greaters moult into breeding plumage about two months earlier than Lessers, so most birds in breeding plumage are Greaters and vice versa. On the other hand, leg colour at Kapar was of no use - all species showed yellowish legs - courtesy of the light-coloured mud they'd been wading in!





































It was hot out there!

































Exceptionally, some Greaters show a blackish border to the breast band - fewer than 1 in a thousand I would guess. I photographed a similar bird in April 2008.


















































It was interesting to see the variation in the amount of orange in the crown and upperpart plumage.


















I think this is probably a female.















I spent some time trying to find a 'mongolus' Lesser Sand Plover, recently mooted as a full species. This dark bird (left) with some smudginess on the fore flanks was the closest I came, but after some scrutiny I decided that it was still just a 'schaeferi'. I've yet to identify any other taxon of Lesser in Malaysia.




















While on the subject of plovers, here are a couple of big Grey Plovers from the big pond.
















When they're in breeding plumage, you can see why the Americans prefer to call them Black-bellied Plover.



















What do you make of this then?




































This should make it easier - a Broad-billed Sandpiper. You weren't thinking of that other 'billed Sandpiper' were you?


















Oh, and there was one nervous-looking Terek in the plover roost - this one really does have yellow legs!.























This is that other-billed sandpiper - Spoonie! (hopefully you can find it!). Looking for a Spoon-billed Sandpiper at Kapar is a truly herculean task - the birds are crammed together, milling about constantly, and sifting through hundreds of Red-necked Stints in the slim hope of scoring what is probably the only Spoon-billed Sandpiper for hundreds of miles is possibly one definition of obsession!






















You've got it now, right? Check out the unstreaked breast sides, white forehead and large head. Single birds have been recorded at Kapar in 2001, 2002, 2007, 2008, 2009, 2011 and now 2012. I wonder if perhaps there are just one or two individuals involved in all these sightings? If they survive to adulthood, Spoonies are known to be long-lived, so I think it's possible that this is the same bird coming back year after year to winter on the Klang Islands. It's sobering to think that this one bird could represent half a per cent of the world population now.


















The gap between this picture and the previous one hides an hour of tension - from the moment the bird slipped out of view behind another bird (with only me having seen it!) until we managed to locate it aqain right at the back of the flock as the clock ticked round to 7 pm. That exhausting period was spent with seven of us (we were joined by Ang) intensely scrutinizing every stint through scopes repeatedly. At times like this, even I would question whether wader-watching is 'fun'! Hard slog and eye-strain, more like!


















Fortunately this time the bird remained stationary, and more or less in view, for long enough for everyone to get least a fleeting view through my scope.

If you want to see a Spoon-billed Sandpiper, I would recommend going to Kok Kham in Thailand, but if you want the immense satisfaction of finding your own on home turf (along with the pain of spending hours and hours of fruitless searching!), then Kapar is, in my view, the ultimate testing ground! For better pics of perhaps the same bird, see here and here.

23 - 25 March 2012: Kapar power station.5. Terns and Gulls

Gull-billed Tern and Caspian Tern are rare species pretty much everywhere in Peninsular Malaysia. I can't recall having seen either away from the Selangor coast, yet at Kapar, they seem to be always present.



We counted 1070 at the high tide roost, with many coming into breeding plumage.







The flock made interesting shapes when they periodically flew up in panic attacks which seem common to all tern species!




































Sometimes the waders got up as well, lending extra texture and colour. These were mostly Great Knots.



Pairing up?



They look pretty hulking alongside White-winged Terns!



But if Gull-billed Terns are the Hulk, then Caspians are King Kong! There were 32 of these beautiful monsters present.





Regal on the deck or in flight.



It's always worth searching through the Gull-billed flock carefully for something rarer. See what other tern species you can find here (Answer below!).



Ah - here's something a bit different!



An adult non-breeding plumaged small gull with a strangely dark bill and rather white head apart from the dark earspot. Small gulls with blackish bills are exciting in these parts, but as always, it's good to start with the common species first!



Unfortunately, the combination of wing pattern (especially the dark underside to the primaries visible on the left wing on the landed bird), dull red legs and overall proportions reveal that this is not a Saunder's or Bonaparte's Gull, but a Black-headed Gull with an aberrantly-coloured bill. On 1 April 2000, some fortunate visiting birders found South-east Asia's first Laughing Gull right here. It was no April Fool, and I'd love to see it repeated, but ... looks like it won't be this year!







Answer:


White-winged Tern (circled in blue); Common Tern (circled in red).

23 - 25 March 2012: Kapar power station.4. Shanks etc.



Here are all the Tringas, or shanks, on offer at Kapar. Four species - have a go at identifying them, then see how you got on at the bottom of the post.



Well, obviously this is a (Common) REDshank!



This is a mix of Common Redshanks, Terek Sandpipers and Curlew Sandpipers. The redshanks and Tereks moved off before it got light.



A Common Greenshank (front) with three Nordmann's.



The thin white line! Remarkably, there were periods during which the commonest Tringa in view was Nordmann's Greenshank. I counted 46 birds, the joint highest count at Kapar over the years (46 were also counted on 3rd Jan 2010). 40 are in this video - see if you can find them all! I think it illustrates well how easy it is to underestimate/undercount birds at roosts. They so easily get lost behind each other!





A couple flashing those pearly underwings!









Ever since I found my first one at Beidaihe in 1986, when we barely knew what one was supposed to look like, NGs have been special birds for me. So having this flock in view for three days was a great treat.











I still have some way to go on my flight shots!







Answer: (front to back) Marsh Sandpiper, Common Greenshank, Common Redshank, Nordmann's Greenshank (and Bar-tailed Godwit).
