This Greater coucal was not learning to fly, rather it had been soaked during a particularly heavy tropical rainstorm in Phuket – the shot was taken in July 2020. The second shot shows this strange and ungainly bird once it had regained its equilibrium and was about to fly down to the ground to feast on a lunch of snails.
