Crested Hawk-Eagle (Nisaetus cirrhatus)

The Crested Hawk-Eagle is a striking raptor with bold plumage, prominent crest, and powerful build, renowned for its predatory prowess within Sri Lanka’s wet zone forests. It is an apex predator of mid-sized birds, reptiles, and mammals, and its stealthy hunting techniques and keen eyesight make it a master of the forest canopy.

🌎 Habitat & Distribution
🌳 Habitat

This species inhabits dense wet zone forests, forest edges, and montane forests, where tall trees provide ideal perching and nesting sites. Crested Hawk-Eagles prefer undisturbed forest interiors with open canopy gaps that allow them to hunt effectively.

📍 Distribution

In Sri Lanka, it is commonly observed in Sinharaja Forest Reserve and its buffer zones, extending to other wet zone lowland and mid-elevation forests. Its presence is indicative of healthy forest ecosystems with abundant prey availability.

🦅 Behavior
Feeding Behavior

The Crested Hawk-Eagle is a diurnal predator, relying on stealth and powerful strikes to capture prey. Its diet includes medium-sized birds, mammals, reptiles, and occasionally amphibians. It often hunts from a high perch, scanning the surroundings, before swooping down with remarkable speed and precision.

Social Behavior

Primarily solitary and territorial, Crested Hawk-Eagles defend their hunting grounds aggressively. They maintain pair bonds during breeding season, but outside of that, individuals are rarely observed together.

Vocalization

The species emits piercing, high-pitched whistles and loud, rapid calls during territorial disputes or when alarmed. These calls are often heard early in the morning or late afternoon.

Breeding & Nesting

Nesting occurs on large, tall trees, where a robust stick nest is constructed, usually hidden within dense foliage. A typical clutch contains 1–2 eggs, incubated primarily by the female, while the male provides food. The species requires mature forest habitats to ensure nesting success.

⚠ Conservation Status

Crested Hawk-Eagles are listed as Least Concern, yet they remain vulnerable to deforestation, hunting, and habitat fragmentation. Preservation of large tracts of wet zone forest is essential to maintain populations of this apex predator.

📸 My Wildscape Encounter

I photographed the Crested Hawk-Eagle in the Sinharaja buffer zone, using a Canon 80D with a 150–600 mm lens. Observing this formidable raptor highlighted its strength, agility, and precision hunting techniques.

This encounter reinforced the importance of patient observation and understanding forest predator behavior, offering a unique glimpse into the life of Sri Lanka’s top avian predators.
