If 90% of the population call them seagulls, and 99% of the population understand what you mean when you say “seagull”, then yes, they are actually called seagulls
50 species of gulls and every last one of them is a cunt.
The very first line of the Wikipedia entry on Gull says: "Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. ". Colloquially speaking all gulls are seagulls.
https://en.wikipedia.org/wiki/Gull
The entry lists 54 species of Gull, and indeed from a pedantic perspective, none of their common names are “seagull”. Nor are any of their binomial names Latin for “seagull”. But there is Larus pacificus, either very calm or associated with the ocean of the same name. Also there is Larus atlanticus, and Larus Marinus (pretty dang close).
I’d just like to interject for a moment. What you’re refering to as a Gull, is in fact, Sea/Gull, or as I’ve recently taken to calling it, Sea plus Gull. Gull is not an categorization unto itself, but rather another component of a full identity made useful by the kingdom, phylum, class, order, family, genus, and species components comprising a full identification as defined by its scientific classification.
