Picture taken during my recent trip to the remote Xinjing province in Northwest China. The giant Swan goose, probably a mom, was seen swimming calmly and gracefully together with a flock of goslings in a pond, but for whatever the reason at the moment, it all of a sudden started flapping its massive wings and chasing one of the babies. Nikon D800, AF-S Nikkor 80-400mm G ED at 400mm, f/8, 1/500 sec., ISO 160. Cropped and lightly adjusted on Lightroom 6.
