I photographed this vulture as he was flying about near a giraffe kill in the Sabi Sand Nature Reserve in South Africa. 40D, 100-400, ISO 320, f 6.3, 1/320.
Could also add a suggestion Would consider a higher ISO for obtaining a higher SS I think the bird could be sharper and might have to do with the 1/320 It is all a trade but think you would be coming out ahead !!!! Love the bg !!!
