© The Neotropical Ornithological Society. Through efforts of the Wildlife Conservation Society, poaching in an important Scarlet Macaw (Ara Macao cyanoptera) nesting area in the Maya Biosphere Reserve in Guatemala had been reduced to zero by 2004. However, during long-term monitoring of the nesting success of Scarlet Macaws in the Maya Biosphere Reserve, unexplained or unknown disappearance of chicks from nests was common despite the aforementioned reduction in poaching. To determine the cause of these disappearances, we installed five video camera surveillance systems in the nest cavities during the 2008 nesting season. Fatal attacks on chicks by Collared Forest Falcons (Micrastur semitorquatus) were recorded at three of these nests. This result highlights natural predation as a limiting factor for the recruitment of new individuals into the Scarlet Macaw population in the Maya Biosphere Reserve even when poaching is suppressed.
