After very heavy rain which clearly mussed the feathers, this Greater Coucal was caught mid-preen, the wing feathers fanned out to dry while much attention was given to the rest. It looks a little miffed at my intrusion, even though I was about 30 metres away and hiding behind the lens.

Canon 90D with Sigma 150-600 f5-6.3 zoom at 600mm. ISO 2000 1/400 at f8, handheld, processed and cropped in LR.
