The bald eagle became the United States national bird through a deliberate design process that culminated in the Great Seal of the United States, adopted by Congress on June 20, 1782.
Over months in 1776 and 1781, a committee led by figures such as Thomas Jefferson, Benjamin Franklin, and John Adams proposed various motifs before Charles Thomson’s final design centered on a bald eagle.
Congress chose the eagle as a symbol of strength, independence, and long life, and gave it a shield with thirteen stripes to represent the original states.
This official seal established the bald eagle at the nation’s symbolic center, a status later reinforced by law and enduring cultural use.
Background Leading to the Decision
In the decade before the bald eagle’s formal adoption, American leaders sought visual symbols that expressed their break from Britain and their aspirations for the new republic.
Artists, engravers, and committee members experimented with plants, animals, and classical figures as possible emblems for seals, coins, and official documents.
By the time the Great Seal committee convened, the idea of a distinctive national emblem was already prominent in political culture.
Committee Work in the 1770s and 1780s
Earlier committees in 1776 and 1777 proposed different designs, including the rattlesnake, which appeared on early flags and publications.
In 1781, Congress referred the question of a final seal to a smaller committee that included Jefferson, Franklin, and Adams, though their initial work did not immediately yield a final result.
Charles Thomson, secretary to Congress, synthesized these efforts into a single, coherent design that placed the bald eagle at the center of the Great Seal.
Formal Adoption by Congress
On June 20, 1782, Congress adopted the final design for the Great Seal, legally establishing the bald eagle as the national bird within the official emblem of the United States.
The legislative record notes that the eagle was to hold an olive branch and arrows, symbolizing both peace and readiness to defend the nation.
Thomson’s description accompanying the design framed the eagle as a representation of authority derived from the people, consistent with the Constitution’s later ratification in 1788.
Design Details of the Great Seal
The bald eagle in the seal is depicted with outspread wings, a shield on its breast bearing thirteen red and white stripes, and a banner in its beak stating E Pluribus Unum.
Congress specified that the eagle grasps an olive branch in its right talon and arrows in its left, intended to communicate a preference for peace while maintaining military capability.
These elements together created a clear, lasting image that linked the bird to the nation’s identity and governmental philosophy.

Rationale for Choosing the Bald Eagle
Committee members described the bald eagle as a bird of strength, longevity, and native distinctiveness, noting its presence only in North America.
The choice was also practical: the bald eagle was already familiar to Americans through prints, natural histories, and regional observation.
Although debates about the appropriateness of a predatory bird for a peaceful republic appeared in correspondence, the eagle’s visual power and symbolic associations ultimately prevailed.
Legal and Cultural Reinforcement
Subsequent statutes, including the Bald and Golden Eagle Protection Act of 1940, reinforced the bird’s protected status and reflected its national importance.
Presidential seals, military insignia, and currency incorporated the eagle, embedding it more deeply into everyday representations of the United States.
By the twentieth century, the bird’s image was firmly tied to civic identity, despite ongoing public affection for other native species.
Enduring Symbolism and Legacy
The bald eagle remains the focal point of the Great Seal and a widely recognized emblem of the United States government.
Its use in diplomacy, ceremonial contexts, and popular culture continues to communicate stability, authority, and national unity.
Ongoing conservation success has further strengthened its role as a living symbol of both the nation and its environmental heritage.
