Why Is a Group of Eagles Called a 'Convocation'?

The Majestic Lexicon: Why Eagles Gather as a 'Convocation'

English is uniquely obsessed with specialized collective nouns for animals, a linguistic tradition largely inherited from medieval hunting manuals and aristocratic pastime books. While common animals earned simple plurals—like a herd of cows or a flock of sheep—apex predators and game birds were granted poetic, highly specific designations. Among the most striking of these is the term for a gathering of eagles: a convocation.

Historical Origins and Etymology

The word convocation derives directly from the Latin convocatio, meaning "a calling together" (from con-, meaning "together," and vocare, meaning "to call"). Historically, the word was primarily ecclesiastical or academic, referring to a formal assembly of clergy or members of a university. Applying it to eagles likely stems from both their imposing, almost regal demeanor and observations of rare communal gatherings, such as during seasonal migrations or abundant feeding sites where dozens of these solitary raptors might temporarily congregate.

In medieval Europe, texts like the Book of Saint Albans (1486)—a foundational treatise on hawking, hunting, and coat armour—codified many of these terms of venery. While 'convocation' captures the dignified gravity of these birds, English lexicography offers several alternative terms depending on context:

• A Tower: Refers specifically to eagles soaring high in the sky, evoking their mastery of altitude.
• A Booth: An archaic term occasionally used when eagles are nesting or perched.
• A Blether: A lesser-known historical term, sometimes denoting a noisy gathering.

Modern Nuance and Psychological Resonance

Psychologically, collective nouns for majestic animals tap into our innate tendency to anthropomorphize and mythologize nature. The word convocation imbues eagles with an almost human sense of council, wisdom, and deliberate governance—fitting for a creature that has served as a universal symbol of empire, freedom, and divine power since ancient Sumerian and Roman times.

While rarely used in strict scientific ornithology—where behaviorists simply speak of 'eagles' or 'flocks' in migration contexts—the term survives strongly in popular culture, trivia, and literature as a testament to the rich, imaginative tapestry of the English language.
