World renowned heron expert and co-founder the IUCN Heron Specialist Group, Jim Kushlan, visited the Pacuare Reserve in May 2015 to study the colony of agami (Agamia Agami) herons. He confirmed our understanding that only five breeding colonies are known and of those, the one at the Pacuare Reserve is the only one truly accessible. This colony could be drawing birds from all over Central America into this colony.
The IUCN Red List of Threatened Species has said "Based on a model of future deforestation in the Amazon basin, and its susceptibility to hunting, it is suspected that the population of this species will decline rapidly over the next three generations, and it has therefore been uplisted to Vulnerable."
Based on this, Pacuare Reserve is extremely lucky to see such a fantastic colony which is so accessible to its visitors.
