Raptor

맹금류

Definition

A predatory bird with keen eyesight, strong talons, and a hooked beak, including eagles, hawks, and owls.

Detailed Explanation

Raptors are apex predators whose populations reflect ecosystem health — they concentrate pesticides and heavy metals through biomagnification, making them sensitive indicators of environmental contamination. DDT-induced eggshell thinning nearly extirpated peregrine falcons and bald eagles before the pesticide's 1972 US ban; both have since recovered. Raptors regulate rodent and bird populations, and their decline can trigger rodent outbreaks with agricultural and public health consequences.
