Cocoi Heron

The Story

I made this photo of a Cocoi Heron (Ardea cocoi) at La Charca de Guarinocito in La Dorada, Caldas, Colombia. The Cocoi Heron ranges from Central America to the Strait of Magellan. It uses almost any body of water or wetland away from dense forest, including lake shores, swamps, rivers and estuaries. It prefers fish and mammals as prey over insects. The Charca de Guarinocito is an old channel of the Magdalena in La Dorada, protected since 1988 and now delimited by Corpocaldas at 167 hectares. IUCN lists the Cocoi Heron as Least Concern, with a stable population.

I used a Pentax K-1 with the HD Pentax-D FA 150-450mm f/4.5-5.6 for this one, at 1/160 sec, f/5.6, ISO 100. In 2025 Corpocaldas zoned the charca for preservation, restoration and sustainable use, recognizing its role in community tourism and artisanal fishing.
