I recently had the honor of spending 12 days with Bob and Ann Walton in Central and Northern Thailand. They have birded 50 some years and seen over 8000 species so it was a challenge to find lifers for them. This Red-billed Scimitar Babbler was to be the last of the lifers with me which tallied up to 32 for the 12 days we had together.
Dave Sargeant had tipped me off to a place at Doi Lang where he had previously seen these birds. Sure enough, a pair of them came in to playback and stayed around for some time.
This was only my 2nd encounter of these birds in Thailand so I was very pleased.
I haven't been able to find many pix of the birds online so I suppose it isn't that common anywhere in it's range.
