Skua on the Lookout - 5D3, 24-70 @ 38mm, f/9, 1/250s, ISO 100.
I find Skuas to be hard birds to like. They generally get their food by stealing it from other seabirds and in Antarctica they go after Penguin chicks. To top it off they are also aggressive. I guess they are the thieving jerks of the animal kingdom.
