“…Each of these breeders hold over several adult individuals, and other private breeders have a smaller number of adults and young animals totaling several dozens in Brazil [110]. Meanwhile, The Peregrine Fund has developed a huge amount of know-how on Harpy Eagle reintroductions during a directed restoration effort for the species in Mesoamerica [64,111–113]. In addition, the Brazilian Harpy Eagle Conservation Program successfully released several rehabilitated individuals [61].…”

The highly interactive nature of predator-prey relationship is essential for ecosystem conservation; predators have been extirpated, however, from entire ecosystems all over the Earth. Reintroductions comprise a management technique to reverse this trend. Species Distribution Models (SDM) are preemptive tools for release-site selection, and can define levels of habitat quality over the species distribution. The Atlantic Forest of South America has lost most of its apex predators, and Harpy Eagles Harpia harpyja —Earth’s largest eagle—are now limited to few forest pockets in this domain. Harpy Eagles are supposedly widespread in the Amazon Forest, however, where habitat loss and degradation is advancing at a rapid pace. We aim to describe the suitability of threatened Amazonian landscapes for this eagle. We also aim to assess the suitability of remaining Atlantic Forest sites for Harpy Eagle reintroductions. Here we show that that considerable eagle habitat has already been lost in Amazonia due to the expansion of the “Arc of Deforestation”, and that Amazonian forests currently represent 93% of the current distribution of the species. We also show that the Serra do Mar protected areas in southeastern Brazil is the most promising region for Harpy Eagle reintroductions in the Atlantic Forest. Reintroduction and captive breeding programs have been undertaken for Harpy Eagles, building the technical and biological basis for a successful restoration framework. Our distribution range for this species represents a 41% reduction of what is currently proposed by IUCN. Furthermore, habitat loss in Amazonia, combined with industrial logging and hunting suggest that the conservation status of this species should be reassessed. We suggest researchers and conservation practitioners can use this work to help expand efforts to conserve Harpy Eagles and their natural habitats.

“…Densities as low as 3 to 6 nests per 100 km 2 (Vargas-González & Vargas, 2011) make the ornithological community celebrate every nest discovery (Pereira & Salzo, 2006; Rotenberg, Marlin, Pop, & Garcia, 2012; Ubaid, Ferreira, de Oliveira, & Antas, 2011). Half a century of research on the species has identified over 50 nests that allowed the collection of more than one thousand individual prey remains (Miranda, Campbell-Thompson, Muela, & Vargas, 2017). Nevertheless, these discoveries were made by indigenous people, poachers, loggers, and other people involved in a diverse range of land uses.…”

Apex predators are in widespread decline, in many occasions as a consequence of the demise of their prey. Harpy Eagles (Harpia harpyja) are the largest extant eagles on Earth and keystone predators in the tropical forests they inhabit. Although Harpy Eagle prey composition has been described by a number of studies, diet data from primary forests are rare on the literature. Here, I describe the diet of Harpy Eagles living in the Central Suriname Reserve primary forests and review literature data to provide an accessible reference to all known reports of Harpy Eagle prey species. In Central Suriname Nature Reserve, Harpy Eagles made frequent use of game prey such as large primates, large birds, and terrestrial animals, besides what is considered their staple prey, sloths. Nine new prey species were recorded, most of them game animals. This totals 102 prey species when summed with literature data. This information provides new insights into the autecology of Harpy Eagles in Neotropical forests, enabling a better understanding of the ecological effects of apex predator.

“…Despite their large trophic spectrum and evidence that mammalian mesopredators are regular prey of both species (Lourenc ßo et al 2011), research has until now only focused on the effects of Eagle-Owl presence on intraguild avian predators. This natural recolonization process could be used as a before-after-control-impact (BACI) experimental design integrating methodological aspects described in the previous section (monitoring mesopredator spatial (Miranda 2015, Miranda et al 2018. Further research is needed on the role of these large eagles on mesopredator habitat use and population dynamics in diverse ecosystems.…”
