Jonathan saw it first about a mile off, but it wasn't clear what it was, so we followed it up, soon seeing a large, long-tailed babbler flushing from in front of us. Some pishing brought it in, whereupon it was immediately obvious what it was, those lovely black and white striations on the nape wrapping round and hugging the bend of the wing made it immediately identifiable. We swore a bit and then Chamnan and Virak brought the car over so that Jonathan could get some great photographs. It sang on and off from the top of low scrub for about an hour. I got a sound recording. More details to follow in the December BirdingASIA - free with OBC membership - if you're not already a member then you should be!
Also on site were five male Bengal Florican, five Comb Duck and lots of seed eating birds, Red Avadavat, Asian Golden and Baya Weaver, plus two Lesser Adjutants.
15 JUNE UPDATE
Jonathan and I returned to the site with Ashish, Howie and the SVC guys. We had a great time and saw about eight Rufous-rumped Grassbirds in just a few hours before it began to pour with rain. Plenty of other good birds about: Bengal Floricans, three species of weaver, munias, lots of Openbill Storks with a few Painted Storks and a Spot-billed Pelican thrown in for good measure.
This is a really exciting site which unfortunately won't be accessible again until the next dry season...I'm looking forward to heading back in the winter!
Here are some of Ashish's photos from the day:
