On a photo tour of Botswana I came across an iconic bird, the Southern Ground Hornbill. These two were parading through a grassy area looking for dinner and they were finding it. Everything from small lizards to insects to rodents. Camera was a Canon 7D with a Canon 500mm f4 lens photographed from a safari vehicle. Settings as follows. Aperture was 5.6, speed was 1/800 sec and ISO was at 100.
