In case of interest, here are my Railbabbler records, most from TN and all those seen were after whistling/playback...
#Way Kambas: 1 calling and seen well. First heard to call from fairly open area of forest next to the main track a few kms from the clearing. Quickly glimpsed moving through the dense ground cover (a reasonable view with the smooth, rufous back seen well, leaving me quite astonished). Then responded to our whistles and furtively circled at about 10m, occasionally allowing further brief views. Once ran along an exposed log giving a fantastic view of the whole bird. Also seen to fly a couple of times.
#2 calling in the muddy gully close to Yong hide. Brilliant views of 1 over 30 mins, at ranges down to 3m. Calling frequently in response to my whistles, the blue airsacks inflating as the bird stooped with its chest to the ground on each call. A Garnet Pitta also came in close calling but didn't show.
#1 heard only near Simpon
#1 calling and seen briefly from trail back from Kumbang
#Way Titias: 1 probable heard only during the walk out
#1 calling for a long time on Jenet Mudah and eventually glimpsed with the naked eye
#1 heard only on the swamp loop
#1 calling and watched on and off for 30 mins beside the river crossing near Kumbang hide. Incredible views, down to 3m and on the trail at times.
Paul, they were variously in March, April, July and August so quite a good spread. Great to see you briefly in Sussex the other day...!
Sorry, just went back and looked - I used the avibase web pages that Paul mentioned. There’s a Pen Malaysia option tucked away...
The important gen is I'm now in Kuala Tahan and contrary to popular belief several places serve beer and there's a shop selling beer, wine and spirits.
