I recorded this video from my rolling bird blind (aka my truck) one August morning near Hinton, Alberta. Equipment used was a Nikon D4 and a 600mm Nikkor lens with a 1.4 teleconverter, 2.7 crop mode, HD video. Things are unfortunately a little bit shaky at times due to the difficulty in keeping a large lens stable on a bean bag. You will hear the sound of a passing vehicle early on in the video as the hawk was near a roadway. Hope you enjoy!
