The Story
On June 25, 2017, I photographed this Cocoi Heron (Ardea cocoi) at the Charca de Guarinocito near La Dorada, Caldas, Colombia. It lives at almost any body of water away from dense forest, including lake shores, swamps, rivers and estuaries. In South America it is widely known as the garza mora. It is a large heron found across much of South America, mostly pale gray with a darker gray crest. The Charca de Guarinocito is an old oxbow of the Magdalena River that stays connected to the river all year.
I used a Canon EOS 70D and the EF400mm f/5.6L USM for this one, at 1/1000 sec, f/5.6, ISO 500. IUCN lists the Cocoi Heron as Least Concern with a stable population, and people living around the lagoon see the birds as an attraction for visitors and do not allow them to be hunted.
