This was a little later in the Bat Falcon series, the sun was beginning to set at Calakmul. No funny leg poses or facial expressions, just a more natural regal pose from one of these incredible birds. Definitely one of my top highlights of my 2 week Mexico adventure. Calakmul, Campeche, Mexico December 23, 2009. Taken with a Canon EOS 50D and a Canon EF 500mm f/4L IS USM with a Canon EF 1.4x II Extender.
