  author={Francisca Helena Aguiar-Silva and T{\^a}nia Margarete Sanaiotti and Benjamim Bordallo Luz},
Abstract The Harpy Eagle (Harpia harpyja), the heaviest and the most powerful bird of prey in the canopy of the Neotropical rainforests, is critically endangered in some parts of its range, mainly due to hunting pressure and habitat loss by deforestation. In this study, we found that the diet of five breeding pairs of Harpy Eagles in the central Amazonian rainforest over three years was dominated by two species of sloths (Bradypus variegatus and Choloepus didactylus) in terms of number of… 

Prey Composition of Harpy Eagles (Harpia harpyja) in Raleighvallen, Suriname

The diet of Harpy Eagles living in the Central Suriname Reserve primary forests is described and literature data is reviewed to provide an accessible reference to all known reports ofHarpy Eagle prey species, enabling a better understanding of the ecological effects of apex predator.

Resource availability and diet in Harpy Eagle breeding territories on the Xingu River, Brazilian Amazon.

It is believed that it is important to consider the protection of remnants of forested areas in the landscape matrix surrounding the breeding territories to maintain the food resource availability and allow all pairs to successfully reproduce.

Deforestation May Trigger Black-and-Chestnut Eagle (Spizaetus isidori) Predation on Domestic Fowl

In anthropogenically transformed habitats, some birds of prey feed on domestic animals, triggering conflict between people and predators. To manage this conflict, it is important to understand the

Feeding Ecology of the Long-Legged Buzzard and Diet Overlap with Sympatric Bonelli's Eagle On Cyprus

The Long-legged Buzzard is a relative newcomer to the island of Cyprus, where it is sympatric with the larger Bonelli's Eagle, a potential competitor for both food and space (nesting territories).

Tropical deforestation induces thresholds of reproductive viability and habitat suitability in Earth’s largest eagles

It is indicated that 35% of the entire 428,800-km2 Amazonian ‘Arc of Deforestation’ study region cannot support breeding harpy eagle populations, and the results suggest that restoringHarpy eagle population viability within highly fragmented forest landscapes critically depends on decisive forest conservation action.

Trial Restoration of the Harpy Eagle, a Large, Long-lived, Tropical Forest Raptor, in Panama and Belize

Re-laying induced by collecting eggs for artificial incubation increased the number of viable eggs laid per female each breeding season up to six, but may have reduced female reproductive lifetime.

Abundance of Harpy and Crested Eagles from a reservoir-impact area in the Low- and Mid-Xingu River

Abstract In the Brazilian Amazon, two monospecific genera, the Harpy Eagle and Crested Eagle have low densities and are classified by IUCN as Near Threatened due to habitat loss, deforestation,

Juvenile Dispersal of Harpy Eagles (Harpia harpyja) in Ecuador

Abstract The movement ecology of Harpy Eagles (Harpia harpyja) is poorly known due to the difficulty observing this species. We studied the movements of two juvenile Harpy Eagles before and during

Abundance of Harpy and Crested Eagles from a reservoir-impact area in the Low- and Mid-Xingu River.

Evaluating occurrence of large raptors in the Brazilian Amazon using the environmental surveys database from Belo Monte Hydroelectric Power Plant found terrestrial surveys (RAPELD method) were more efficient for detecting large raptor detection than standardized aquatic surveys, although the latter were complementary in areas without modules.



Predatory behavior of crowned hawk-eagles (Stephanoaetus coronatus) in Kibale National Park, Uganda

Results indicate that primates form the vast majority of all prey items and that a non-trivial fraction of the entire primate population at Ngogo succumbs to crowned hawk-eagle predation each year.

Spatial and temporal patterns in the diet of the Andean condor: ecological replacement of native fauna by exotic species

The results show the abundance of the invasive species in northwestern Patagonia and support the idea that native mega-herbivores are ecologically extinct in this area.

Crowned eagles rarely prey on livestock in central Argentina: persecution is not justified

The results show that crowned eagles rarely prey on livestock, and advocate reducing human-wildlife conflicts by imple- menting management and conservation measures and by educating local communities with respect to the ecological role of crowned e Eagles and other predators.

Notes on the Harpy Eagle in British Guiana

In British Guiana, from December, 1959, to May, 1960, the authors made many observations at the nest sites of two families of Harpy Eagles, either from a blind or from other concealment in the immediate vicinity of their nest trees, and think these are among the first detailed observations ofHarpy Eagles in their native habitat.

A Preliminary Analysis of a Neotropical Mammal Fauna

The abundance and biomass of species of nonvolant mammals on Barro Colorado Island are estimated and compared with data from other areas. The edentates, particularly the sloths, are shown to be


A male and female Harpy Eagle (Harpia harpyja), both reintroduced captive-bred subadults, were observed on Barro Colorado Island, Panama for 89 and 205 days, respectively, between June 1999 and August 2000 and the female eagle was observed to capture solitary arboreal prey significantly more during sunny weather and the dry season.

Poachers Alter Mammal Abundance, Seed Dispersal, and Seed Predation in a Neotropical Forest

The hypothesis that poachers reduce the abundance of herbivorous mammals, and that this, in turn, alters seed dispersal, seed predation, and seedling recruitment for two palms in central Panama is evaluated.

Curiosity killed the bird: arbitrary hunting of Harpy Eagles Harpia harpyja on an agricultural frontier in southern Brazilian Amazonia

in southern Brazilian Amazonia, severalinterviewees reported Harpy Eagle kills, which arepresented and discussed here. Whilst the extent ofits effects on the local Harpy Eagle population isunclear,

Harpy eagle sightings, traces and nesting records at the “reserva Natural Vale”, a Brazilian atlantic Forest remnant in espírito Santo, Brazil.

We present 25 records of sightings, feathers and nests of the Harpy Eagle Harpia harpyja in the last 27 years and also the first detailed description of a nest of a Harpy Eagle in the Brazilian

Birds of Conservation Concern in Eastern Acre, Brazil: Distributional Records, Occupancy Estimates, Human-Caused Mortality, and Opportunities for Ecotourism

This work conducts point-count surveys, recorded opportunistic encounters, and estimated occupancy for the globally threatened, near-threatened, and restricted-range birds of eastern Acre, Brazil, and interviews with local hunters suggest that H. harpyja and M. guianensis are rare to uncommon and widely persecuted throughout CMER, although interest in community-run ecotourism presents opportunities to increase conservation of these and other rare species.
