Purple Swamphen (Porphyrio porphyrio).
Location: Tamar Island wetlands, northern Tasmania, Australia
I've often felt that the common name of this species is something of a misnomer. When I encountered it, this particular bird was in the middle of a thorough bath which really brought out its colors, including that incredible shade of blue - more commonly obscured when the birds are smeared with mud. The tight framing is mostly original and was necessary to eliminate distracting details in the foreground and background - but perhaps it works as a portrait?
Equipment: Canon EOS 7D, EF 100-400 L IS II, at 400mm, centre spot servo AF, handheld, shutter priority, 1/500 sec, f10, ISO 400, spot metering
Processing: Adobe CC Lightroom/Photoshop, slight crop to about 90% of original frame width, some specular highlights on the upper beak surface were removed, and a couple of reeds overlapping onto the bird were cloned out.
