mintoni has a generation length of 8.6 years. Species Density The density of this species is believed to be similar to that of the lined forest falcon, at 1 pair per 20-67 hectares. However, densities as high as 3-4 pairs per kilometer have been reported at dawn during dry season. Movement The cryptic forest falcon is believed to be sedentary. It is not migratory. Threats and Conservation Status The IUCN classified the cryptic forest falcon as least concern in 2016, which is consistent with its 2004, 2008, 2009, and 2012 assessments. This is largely due to its extremely large range. This range however, is decreasing. An analysis of forest cover change from 2000 to 2012 showed that this species lost 22% of its habitat within three generations, leading some to believe it should be considered globally Near Threatened. While its population size hasn't been quantified, it is believed to be decreasing. This decrease is largely based on its habitat loss due to deforestation. It is suspected to lose 34-51% of its habitat over three generations (26 years). Atlantic Rainforest Population The population in the Atlantic rainforest, was believed to be critical or extinct upon the species classification, due to habitat loss in that region, as well as no specimens being collected after 1933 (originally classified as lined forest falcons, later recognized as cryptic forest falcons). Until 2012, when it was rediscovered in Southern Brazil. Further research is needed to quantify this population and its remaining range in the region. This population is likely critically endangered. History Specimens of the cryptic forest falcon were historically categorized as lined forest falcons. It was first recognized as a new species by Andrew Whittaker in 2002, when he heard its distinctive vocalizations. Museum specimens verified that it also slightly differed from other members of the genus in physical characteristics. Whittaker subsequently named the species Micrastur mintoni, in memoriam of shore-bird ornithologist Clive D. T. Minton, Whittaker's mentor.
