We met enormous bird with blue head with a silver Mohican, a golden brown chest and enormous spotted feathers reaching out behind — like those of a peacock. It was the elusive and rare Great Argus. In the clearing the Argus was tidying away the dead leaves, preparing a space to dance in, to impress and woo a female. The mating call is beautifully simple, a two-toned caw, unmistakeable.
