The 4th species, Sunda Laughingthrush can only be found in Sabah & Sarawak.
Yesterday birding/photography didn't produce many birds. The weather was dry and the bird seems to be hiding. Anyway, I am happy to find my last Laughingthrush, which is my lifer.
Met MikeBirder up there, he is using the new Canon 7D and same lens as mine.
