Many raptors rely heavily on auditory cues when hunting in visually complex habitats.
Harpy Eagles rely on acute hearing and subtle forest acoustics to detect prey movement. Expanding road networks and mechanized logging introduce persistent low-frequency noise into previously quiet habitats. Background noise can mask the faint rustling of sloths or monkeys moving through leaves. Reduced acoustic clarity may lower hunting efficiency. In species with low reproductive rates, even minor decreases in prey capture success can affect chick survival. Sensory disruption compounds structural habitat change. Quiet forests support effective predation.

Anthropogenic noise alters animal behavior across trophic levels. Prey may modify movement patterns, while predators lose detection advantage. In dense canopy systems, sound is often as critical as sight. Acoustic degradation may therefore have invisible yet measurable demographic effects.
Managing infrastructure development to preserve quiet buffer zones could support apex predator persistence. The Harpy Eagle’s sensory adaptations evolved in natural acoustic environments. Sustained mechanical noise reshapes ecological interactions in ways that are difficult to reverse.
