This image is from the same series as the previous one posted yesterday. Slender-billed gull. Scientific name: Larus genei.
This is a 1st Winter bird.
Canon EOS 1D Mark IV, Canon EF 400mm f2.8 L IS USM, EF1.4x II, ISO 800, f9, 1/1600, full frame image.
I was handholding and it flew straight towards me and the wing tips got cut.
