The highest priority for future research on Crested Eagle is to better document current ranges and densities. At present, densities are only estimated in a handful of locations and overall population estimates are very vague. Without accurate population estimates, there is uncertainty regarding the conservation status of this species and what special actions are required. Accurate data on population densities throughout the range of Crested Eagle would significantly assist in managing this species. There are additional gaps in our knowledge about this species. (1) It is not known if Crested Eagle migrates or moves significant distances through its life, as does Harpy Eagle (Harpia harpyja). (2) Additional information is needed about mating behavior and selection of nest sites. (3) The extent to which human disturbance affects Crested Eagle distribution in general or especially during the nesting period is unknown. If this is a significant threat, conservation efforts could focus on areas with nesting Crested Eagles or on minimizing particular activities that disturb the birds. (4) Information is needed on the effects of logging on Crested Eagle.
