Crowned Eagle Buteogallus coronatus inhabits open country in eastern and southern Brazil, Bolivia, Paraguay, and northern and central Argentina. Several authors have included Uruguay within the species' range, many of them indicating that it is presumably extinct in the country. Here we evaluate the available evidence concerning its presence in Uruguay by considering all original reports together with the species' past and current distribution and its habitat requirements. We conclude that unambiguous records in Uruguay are still lacking. Given that the species has recently been observed at several localities in nearby Argentina and Brazil, individuals may reach Uruguay sporadically, probably dispersing juveniles. Effective conservation measures targeted at Crowned Eagle habitat will increase the chances that this threatened raptor may yet colonise Uruguay. © 2014 British Ornithologists' Club.
