The harpy eagle (Harpia harpyja), or harpy, is one of the most remarkable birds of prey in the Americas, especially in the tropical forests of the Amazon region. Renowned for its impressive wingspan of up to 2 meters and weight of up to 9 kilos, this top-of-the-chain predator not only stands out for its imposing size, but also for its crucial ecological importance (SANTOS, 2009).
The royal hawk's distinctive plumage features a mixture of gray-blue tones, highlighted by a characteristic tuft of feathers and an elegantly striped tail. These features not only give the bird a majestic appearance, but also favor its camouflage among the dense foliage of tropical forests, a habitat that stretches from southern Mexico to northern Argentina (ROSA; DRUMOND, 2010).

As a predator at the top of the chain, it has a varied diet that includes mainly medium-sized mammals, such as monkeys and sloths, as well as small terrestrial mammals, and occasionally also captures large birds such as macaws and toucans (SILVA, 2007; BOWLER et al., 2020). Its agility when hunting, combined with its ability to fly silently between the treetops, reveals a remarkable adaptation to the complex forest environment.
In the reproductive cycle, the female usually lays only one egg every two to three years, depositing it in nests located in tall trees (UBAID et al., 2011). Both parents equally share the duties of incubating and feeding the chick, which remains under their care for 10 to 12 months, until it reaches independence (UBAID et al., 2011).
The harpy eagle plays a vital role in maintaining the ecological balance of tropical forests. As a top predator, it exerts significant control over the populations of its prey, helping to regulate the abundance and distribution of these animals within the ecosystem. This is essential to prevent the overpopulation of some species and to promote biological diversity in the region (SILVA, 2007; BOWLER et al., 2020). Additionally, it influences community structure in several ways: selective predation helps shape the dynamics of prey populations, indirectly affecting vegetation and other forms of life in the forest (ROSA; DRUMOND, 2010). Their presence contributes to maintaining a balanced and healthy environment, which is essential for the functioning of natural cycles, such as the decomposition of organic matter and the regeneration of the forest.
The conservation of the harpy eagle not only protects this magnificent species, but also benefits the rich biodiversity of South America's tropical forests. As a bird that uses and needs a large area of forest to reproduce, the harpy eagle is what is known as an umbrella species, favoring the protection of other animals that are at the trophic level below its own (SANTOS, 2009; UBAID et al., 2011).
Despite its iconic status and ecological importance, the Red-shouldered Hawk faces significant threats, such as habitat loss due to deforestation and forest fragmentation, as well as illegal hunting. The implementation of effective conservation measures, such as bills that focus on preventing the clearing of forests and illegal hunting of these animals, are essential to protect these magnificent birds and ensure the survival of their natural habitats (BOWLER et al., 2020). The Harpy Harpy (Harpia harpyja) has IUCN Status: Near Threatened (NT), which is a concern given that its population growth is very slow, and the destruction of large forest areas and indiscriminate hunting make the species threatened with extinction, since the species needs large preserved areas to survive and only nests in the highest trees.
In short, the red-tailed hawk is not only an emblematic figure of the South American rainforests, but also a crucial indicator of the health of these ecosystems. Its conservation not only protects this species, but also contributes to the conservation of all the biodiversity that shares its habitat in the rainforests (SANTOS, 2009; SILVA, 2007).
