The Story
This Cocoi Heron (Ardea cocoi) was at Reserva Natural Hato Berlín in Trinidad, Casanare, Colombia when I photographed it. 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. Hato Berlín is a civil-society nature reserve on the Casanare savanna, about 10 km from Trinidad, where capybaras, caimans, turtles, monkeys and savanna and marsh birds can be seen. IUCN lists the Cocoi Heron as Least Concern, with a stable population.
I made this frame with a Pentax K-1 and the HD Pentax-D FA 150-450mm f/4.5-5.6, at 1/250 sec, f/5.6, ISO 200. In 2020 Hato Berlín opened an eco-lodge as part of the Safari Llanero, a project led by the Casanare Chamber of Commerce with Swiss cooperation to strengthen wildlife-watching tourism.
