Thailand Nov-Dec 08: 1st - 3rd Dec - The Golden Triangle



Burma/Myanmar on the right of the river, Thailand on the left.

Due to my daughter's ambition to set foot in Laos and my ambition to catch up with some good waders around the Mekong, we spent 2 nights in 'The Golden Triangle'. I hadn't realized that this has become the actual name of a town - not sure what its original Thai name was.



The Golden Triangle - so named because at this point three countries meet - Laos on the right, Burma straight ahead, and Thailand on the left (oh, and the rest is the mighty Mekong river!). Also probably so named because it was formerly the area where 'black gold' aka opium poppies were grown, and is now the area where 'pink gold' (aka western tourists) is still enriching the area.



A short boat ride took us to Laos, where you can buy an assortment of health drinks containing pickled creatures - in this case a Pangolin, a lizard and a large snake. There was also a captive bear available for the tourists to gawp at, and shops sold an assortment of products made from elephant ivory. These sad sights reminded me of southern China in the 80s, although I had hoped never to see them again.

On our first morning in the Golden Triangle, we came across a fruiting tree in the middle of the tourist shops.



It attracted several Black-crested Bulbuls...





































...a very obliging Plain Flowerpecker





...a female Scarlet-backed Flowerpecker for comparison





...and, briefly, a bee-eating Yellow-browed Warbler, as well as numerous Olive-backed Sunbirds.

But it was the waders I was really hoping for, in particular Small Pratincole and Long-billed Plover, so the next morning we found our way down to a sandbar on the Mekong to see what we could see.



Dawn on the Mekong - a little chilly, but breathtakingly beautiful.



There were a number of plovers around, including this interesting pale-legged Kentish, but not a Long-billed in sight.



Amazingly, after my first South-east Asian Common Ringed Plover in Sabah just a couple of months ago, we found another on the banks of the Mekong, defending territory aggressively against all-comers, in this case, a Little Ringed Plover.
































































Covering all the angles!





The early morning chill was enlivened by the arrival of several small groups of River Lapwings, with their odd, distinctive stiff-winged, heads-up flight.



On arrival they would energetically display to each other.



Morning formalities completed, they then flew off elsewhere.



The spot we had chosen turned out to be a fine one for observing snipe - in this case, a Pintail Snipe.



I confess I find snipe on the ground very difficult to identify - I just don't see enough. This is another Pintail I believe.



There's quite a range of colour tone between the front and back birds. After much pondering, I have tentatively identified the front bird as a Common Snipe, on the basis of the rather thick dark loral stripe, longish bill and tail, and the dark background colour to the scapulars.



A couple of Pintail Snipe in flight, showing the typically deep chest and round wingtips of Pintail and Swinhoe's and toes projecting beyond the tail tip, which favours Pintail over Swinhoe's.



I was able to confirm their identification as Pintail Snipes when the rear bird obligingly fanned its tail, revealing the pinlike outer tail feathers.



Feeding snipes are very aggressive toward other snipes invading their space, giving me a good chance to see birds in flight. Identification in flight is much more straightforward than when they are on the ground. Here a Common Snipe (left) shows its largely white underwing and white trailing edge to the secondaries. The wings are narrower and sharper than the Pintail Snipe's (right). Pintail and Swinhoe's Snipe have almost crake-like rounded wingtips, lack the pale trailing edge to the wing, and have rather brown upper primaries and secondaries. In addition, the buff edged wing coverts usually create a prominent pale upperwing patch which contrasts with the flight feathers.



Pintail (and Swinhoe's) Snipe have uniformly barred underwings, as can be seen here.





...compared with the more contrasting underwing pattern of Common Snipe.



The white trailing edge of the Common Snipe's wing is well seen here.



And the lack thereof on Pintail Snipe here.





In flight, Swinhoe's might be expected to show more white in the outer tail region than Pintail, by virtue of its broader, paler outer tail feathers. This Pintail Snipe shows very little.



This is a Common Snipe (though I only know that because I saw the wing pattern before it flew in front of the sun!)



I was really pleased to photograph this Green Sandpiper. It's a vagrant to Peninsular Malaysia, and is often mistaken for the much commoner Wood Sandpiper. The upperparts are really dark, making the white rump really stand out. Note also the thick black tail bars, quite different from Wood Sandpiper.



The underwing is blackish too, as opposed to the pale barred underwing of Wood Sandpiper. If you use your imagination you can just about make out this feature here!



And finally, a Temminck's Stint doing its best impression of a Spoon-billed Sandpiper (anyone who thinks Spoon-billed Sandpipers are unmistakable reckon without the fairly frequent occurrence of Muddy-billed Stints - see another example here).

So, no Small Pratincoles or Long-billed Plovers but a pleasing selection all the same!

13th March 2010: Pulau Burung, mainland Penang

I was at the Red-throated Thrush site at dawn to see what would hop up onto the dead trees.



The first thing to attract my attention was a group of three Asian Koels, one of which was holding a feather. No idea what they were up to!



Next up was a preening Lineated Barbet.





Then I spotted a Banded Woodpecker sunning itself at the top of a dead tree.
























Later on it went down the trunk and started excavating a hole.





A Dollarbird was an interested bystander!



Along the coastal bund, the female Common Kingfisher had successfully caught...something - not sure what.

Being a Saturday morning, the Landfill site was fairly crawling with bird photographers in cars. I went past one carload photographing White-browed Crakes and a Lesser Whistling-Duck with ducklings - hope they got some nice pics!










































Even though they are a common bird, I couldn't ignore the Blue-tailed Bee-eaters in the golden early morning light. Stunning!



There are so many birds at Pulau Burung, and they are very habituated to people in cars, with the result that you sometimes encounter an unusual problem for photography - bird too close! This Slaty-breasted Rail was a good example.

The same was true of snipes. I was very keen to photograph some, but they were mainly on the grass verge besiede the road, and so flushed before I realized they were there. At last though, I got lucky.



A Pintail/Swinhoe's feeding out in the open only metres away!





The dull buff edge on both sides of the lower scapulars, and the barred median coverts showed that this was one of the Pintail/Swinhoe's pair, and not a Common Snipe. The problem was, which one?!





The large, squarish head, with the eye set well back favoured Swinhoe's, as did the thickish yellow legs (covered with greyish grime), but I knew I would need to see the outer tail feathers to be able to identify the bird for certain.



This is a sketch of three snipe species' tails from Paul Leader and Geoff Carey's paper on the 'Identification of Pintail Snipe and Swinhoe's Snipe' from British Birds. The dark grey-filled feather is (roughly) at the centre of the tail, so the picture shows only the left side fanned open.The blue-filled outer feathers are the important ones for identification. On Common Snipe, these are similar in breadth and shape to the other tail feathers. On Swinhoe's, the outer feathers become progressively narrower toward the outside, while on Pintail, the outer feathers become abruptly very narrow and pin-like, without much gradation from broad to narrow.

There are usually two chances to see snipe outer tail feathers in the field. One is when they engage in territorial disputes with other birds, when they will fan and raise their tails. The other is when they preen.




I watched this bird for over two hours, and it only preened the tail briefly twice in that time! This was the first occasion...



...And this was the second. On neither did the bird fully fan the tail. Nonetheless, on the first photo, you can see the tips of the undersides of many of the tail feathers.



The feathers on the left side appear to become gradually narrower, fitting the Swinhoe's pattern.

The second picture reveals that the tips of the upperside of the central tail feathers are white. Leader and Carey state, "The central rectrices of Swinhoe’s Snipe may also be conspicuously tipped pale, often white, unlike Pintail," so this seems to be another pro-Swinhoe's feature.



Although not useful for identification purposes, it was interesting to see that the tertials on either side of the bird were at different stages of moult. On the right side, the upper two tertials were new and still growing, while the lowermost one was old and retained very little patterning. On the left side, all the tertials were old and unmoulted.





A couple more pictures of the bird after it had climbed up onto the bund next to the road.

With the bird sitting so close to the road it was only a matter of time before it was flushed, so I had my sound recorder on in the hope of recording the flight call. When it was finally flushed, however, it was completely silent! Leader and Carey say that "When flushed, Swinhoe’s Snipe calls less frequently than Pintail Snipe, and a flushed snipe which is silent is most likely to be the former." However, I am always wary of arguing from silence!







The very short toe projection beyond the tail tip is another pro-Swinhoe's feature which Leader and Carey indicate might be valid. Check out the short toe projection on this vagrant Swinhoe's Snipe in Finland.



Another view of the outer tail on the bird in flight, though probably not conclusive on its own.



My four best shots of the tail!

Wells states that, on the evidence of the analysis of hunting-bags in the 1940s and 50s, Pintail Snipe is overwhelmingly the commonest of the three snipe species in the Peninsula (97 - 99+% of all shot birds analyzed were Pintail). This contrasts with my own admittedly meagre sample; all Pintail/Swinhoe's Snipes I have identified to species this season have been Swinhoe's. Wells suggests that one potential bias in the analysis results is the "partitioning of winter habitats between species, relative to those most often shot over," with the suggestion that Pintail prefers drier, harder substrates than Common and Swinhoe's. In the same way that hunters might prefer to shoot in drier habitats, birders tend to prefer birding in wetter habitats, or at least, it may be true that birds are easier to observe in the open when there is open water. Whatever the case, it may be dangerous to assume that Pintail/Swinhoe's Snipes are 'most likely to be Pintail' based simply on past data.
