The national bird of the United States is the bald eagle, a powerful symbol chosen for its distinctive appearance and long lifespan. Officially adopted through a 1782 congressional seal design and reinforced in 1789 by Secretary of State Thomas Jefferson, the bald eagle embodies freedom, strength, and enduring governance. Protected by federal law under the Bald and Golden Eagle Protection Act and the Migratory Bird Treaty Act, it is recognized across currency, seals, and civic iconography. Below is an evergreen, factual profile of the species, how it became the national bird, and how to identify and support it.
What Is the National Bird of the United States
The bald eagle was declared the national bird of the United States in 1782 when the Great Seal of the United States was adopted. Its selection reflected ideals of liberty, perseverance, and majestic presence. Congress affirmed the choice through the official seal, and the bird has since stood as an enduring emblem of the nation’s identity. The decision was recorded in the congressional journal and has remained consistent across centuries of use.
Origin and Historical Adoption
1782 Congressional Seal Adoption
In 1782, the Second Continental Congress tasked a committee with designing a seal that would reflect the new republic’s values. The chosen design featured an eagle clutching arrows and an olive branch, establishing the bald eagle as a central emblem. Thomas Jefferson and other founding figures supported the image for its associations with authority and independence.
1789 Executive Recognition
When the Constitution took effect, the new federal government continued to use the eagle prominently. In 1789, Secretary of State Thomas Jefferson incorporated the design into the Great Seal of the United States, formalizing the bald eagle’s role as the national bird in official state documents and treaties.
Identification and Physical Traits
Adult bald eagles are unmistakable with their white head and tail contrasting against a dark brown body and wings. Their large yellow bill and powerful talons make them efficient hunters. Juveniles appear mostly dark brown with variable white mottling, gradually acquiring adult plumage by around five years of age.
- Wingspan: 1.8 to 2.3 meters (about 6 to 7.5 feet)
- Body length: roughly 71 to 102 centimeters (28 to 40 inches)
- Weight: approximately 3 to 6 kilograms (6 to 14 pounds)
Legal Protections and Conservation Status
The bald eagle is protected by several key federal laws. The Bald and Golden Eagle Protection Act prohibits take, possession, or sale of the bird, its parts, or nests without a permit. The Migratory Bird Treaty Act extends additional safeguards, and various state regulations reinforce habitat and disturbance protections.

Habitat, Behavior, and Diet
Bald eagles inhabit areas near large bodies of open water where fish are abundant, such as coastlines, lakes, and major rivers. They build substantial stick nests, often reused and enlarged over years. As opportunistic carnivores, they feed mainly on fish but will also scavenge or take small mammals and birds when available.
Conservation Success and Ongoing Challenges
Once listed as endangered due to shooting, habitat loss, and pesticides like DDT, the species rebounded after protections, habitat restoration, and DDT bans. By 2007, it was removed from the U.S. endangered list, though threats such as lead exposure, collisions, and habitat degradation persist. Continued monitoring and nest protection programs help maintain stable populations.
Cultural Significance and Public Perception
Beyond law and science, the bald eagle represents freedom and national unity in civic life. It appears on official seals, currency, and military insignia. Public interest remains high, supported by wildlife watching, educational programs, and media coverage focused on nesting success and conservation outcomes.
How to Identify Eagles in the Wild
Look for large birds with slow, steady wingbeats and a distinctive silhouette: broad wings, flat head, and hooked bill. In flight, adults show a dark body with a contrasting white head and tail. Juveniles are darker with white markings on the underwings and body. Listening for their sharp, whistling calls and observing perch sites near water can aid identification.
Community Involvement and Reporting
Citizen scientists can support conservation by reporting nests and disturbances to local wildlife agencies, participating in eagle counts, and avoiding disturbance during breeding seasons. Responsible viewing practices, such as maintaining distance and avoiding baiting, help protect these iconic birds for future generations.
