The IUCN Red List status for Solitary Eagle is Near Threatened, due to its moderately small population size (1000-2499 mature individuals), and likely declines due to habitat loss (BirdLife International 2015). It has a resident distribution of about 699,000 km2 (BirdLife International 2015). It is considered Endangered under Mexican law (NOM-059 SEMARNAT 2010). This species is also a tropical resident of high tri-national concern (Mexico-U.S.-Canada) to Partners in Flight (Berlanga et al. 2010). Based on determinations of habitat loss, Berlanga et al. (2010) estimated that at least 50% of its population has been lost in Mexico during the last century.
