A freshly bathed male Satin Bowerbird.
The male dives in, shakes off the water & preens fastidiously, before doing it all again, & again for several minutes.
The green females come in late on a hot afternoon but the male seems to leave it until the light is fading.
Canon 5Ds R, EF 70-200 2.8II used in camera trap setup with Cognisys Sabre trigger & 2 580EX II flashes used at 1/16 power.
