The phrase “parliament of bats” does not appear in major encyclopedic references, linguistic corpora, or zoological literature as an established collective noun for the species Chiroptera. Standard sources on collective nouns commonly identify “colony,” “cloud,” or “cave” as the terms most frequently associated with groups of bats. Consequently, the expression lacks verifiable recognition as a formal or widely used term.
Possible interpretations
- Etymological rationale – The word “parliament” has historically been applied metaphorically to groups of animals perceived as gathering in a deliberative or communal manner (e.g., a “parliament of owls”). Applying the same construction to bats may stem from a similar perception of their nocturnal congregations in roosts, though no documented origin has been identified.
- Literary or colloquial usage – The phrase could arise in creative writing, humor, or informal contexts where an author seeks a vivid or whimsical collective noun. No citation from reputable publications verifies such usage.
- Comparison with related terms – Given that “parliament” is an established collective noun for owls, it is plausible that the term has been analogously extended to bats by some writers, albeit without broader acceptance.
In the absence of verifiable sources, “parliament of bats” should be considered a non‑standard or informal expression rather than a recognized term in zoology or lexicography.
