Stalking Heron, Hidden Buffalo (Copyright (cc) 2009 B Kahuna) 

YALA NATIONAL PARK, Sri Lanka -- A grey heron (Ardea cinerea) makes itself an observation deck on the back of an almost completely submerged water buffalo (Bubalus bubalis spp.) at the Yala National Park.

Captured on 21^st June 2009 with a Canon EOS 30D (EF 75-300mm 1:4-5.6 III and Kenko 2X Teleplus Pro 300 teleconverter) on aperture priority (f/5.6) and ISO 800, manually focused. The enhanced contrast was achieved by setting the Picture Style to Clear. The lens was zoomed at 300mm giving an effective focal length of 600mm. This would be equivalent to 960mm in a 35mm camera due to the 1.6X field of view crop on the 30D.
