The Story
I made this photo of a Hoatzin (Opisthocomus hoazin) at Ecohotel La Fortuna in Yopal, Casanare, Colombia. It is a noisy bird, with hoarse calls that include groans, croaks, hisses and grunts. Hoatzin chicks have two claws on each wing, which they use to climb back to the nest after dropping into the water to escape predators. It was once thought to eat only arum and mangrove leaves, but it is now known to eat the leaves of more than 50 plant species. It lives in swamps, riverside forest and mangroves of the Amazon and Orinoco basins. Yopal is the capital of Casanare.
I used a Pentax K-1 with the HD Pentax-D FA 150-450mm f/4.5-5.6 for this one, at 1/500 sec, f/5.6, ISO 6400. IUCN lists the Hoatzin as Least Concern, with a decreasing population.
