“A group of owls is called a parliament.”

The most reliable sources in the pool—HowStuffWorks (Sources 1-2, authority 0.75) and a mainstream newspaper explainer from Deccan Herald (Sources 3-4, authority 0.65)—explicitly state that a group of owls is called a “parliament,” while the remaining support comes largely from lower-authority reference-style sites (Birdfact, Grammar Monster, Inshorts) that are not clearly independently sourced. Because trustworthy sources do confirm “parliament” as an accepted collective noun (even if not the only one), the claim is mostly true rather than perfectly definitive.

The evidence directly supports the claim through multiple independent sources (Sources 1, 6, 7, 9, 10, 13) explicitly stating that "parliament" is a/the collective noun for owls, with Source 6 (Birdfact) and Source 7 (Grammar Monster) confirming it is "the most common" term—the claim uses "is called" which in English allows for multiple valid collective nouns to coexist, not requiring exclusivity. The opponent's rebuttal commits a false precision fallacy by demanding the claim assert uniqueness when standard English usage permits multiple collective nouns for the same animal (e.g., "a pride of lions" and "a troop of lions" are both correct); the claim is TRUE because "parliament" is indeed an accepted and most common collective noun for owls, and the existence of alternatives does not negate this fact.

The claim omits that multiple other collective nouns exist for owls (wisdom, congress, stare, hooting, study) as documented by Sources 6, 7, 8, 11, and 12, though all sources confirm "parliament" is the most common term. Despite this omission, the claim remains substantially true because the phrasing "is called" does not assert exclusivity—languages routinely have multiple valid collective nouns for the same animal, and stating one valid term does not falsely deny others exist; the claim would only be misleading if it said "is only called" or "the correct term is."
