Black-headed gull in flight (Larus ridibundus)
Found this one on a lake. It was angry about me getting close. Those lake gulls are typically not aware of many people passing by because lake it was captured is wild forest lake. So the bird was unhappy of my presence. Full Flickr Version: Canon 6D, Canon EF 100-400L ƒ4.5-5.6 IS USM, at 400mm, ISO100, 1/500, ƒ/7.1
