About
Bald Eagle (Haliaeetus leucocephalus)
The national bird of the United States, admired for its striking white head, powerful talons, and remarkable eyesight.
Physical Characteristics
Bald eagles are large birds of prey with a wingspan reaching up to 2.3 meters. Adults are easily identified by their striking white head and tail contrasting with a dark brown body, along with a sharp yellow beak and powerful talons.
Habitat and Distribution
Bald eagles are found throughout North America, typically near rivers, lakes, and coastlines where fish are abundant. They require tall trees or cliffs for nesting close to open water.
Hunting and Diet
Bald eagles are opportunistic hunters and scavengers, feeding mainly on fish caught in dramatic swooping dives, but also preying on waterfowl and small mammals or scavenging carrion when available.
Conservation Status
Once endangered due to the pesticide DDT thinning their eggshells, bald eagles have made a dramatic recovery since the chemical was banned in the 1970s. They are now listed as Least Concern, a celebrated success story in wildlife conservation.
