Saw three Thick-billed Green-Pigeons (Treron curvirostra curvirostra) in the very early morning under dark skies on a dead tree; 2 males and 1 female. Some images of the males (all 3 images shown here). It had rained in the early morning and they were preening.
I managed to record one call made by a male. Like other Green-Pigeons it is a low frequency (< 6kHz), whistling, melodious, rambling call.
