Larger duck, uncommon in Brisbane surrounds. I was lucky enough to come across 500 or so of them in a massive group, on both sides of a small creek's banks. I couldn't get super close as they were on private property, so this is a reasonably heavy crop. The R3 is great, but when I have to crop, the drop in IQ from lack of pixels on feathers shows. I will eventually get a used original R5.
