| Proposal (#60) to South American Checklist Committee
Change English name of Larus belcheri from "Band-tailed Gull" to "Belcher's Gull" Larus belcheri, endemic to the Humboldt Current of central South America, has long been called Belcher's Gull [e.g., Murphy 1936]. It became a victim of Eisenmann's irrational war on patronyms for birds south of the US. Meyer de Schauensee (1970) used Band-tailed Gull on the recommendation of Eisenmann and most authors have followed suit. With the split of the Atlantic coast Olrog's Gull, L. atlanticus [as in 7th ed.], this is a good opportunity to revert to Belcher's Gull for the Pacific coast birds. 3 reasons 1. Avoid confusion of pre- and post-split Band-tailed Gull;

Plenge, Lima, 2 October 2003 =============================================================================== Comments from Stiles: "[YES]. ... had AOU not gone with Belcher's I would have been perfectly happy to keep Band-tailed (appropriate, if not exclusive/diagnostic). However, since we are an AOU committee it would seem a bit odd if we were to come up with different English names, no? And Belcher's does have the advantage of being a mnemonic for the Latin name.. so, yawning slightly, I'll go with Belcher's." Comments from Stotz: "I tentatively vote YES, change to Belcher's Gull. I guess my argument here is that this is a split atlanticus from belcheri, and should be accompanied by an English name change to avoid confusion. Given that the species is apparently a vagrant to the Gulf of Mexico and Panama, I think it makes sense to be clear that birds belong to the Pacific taxon, and not to an undefined entity that could include both." Comments from Robbins: "[YES] I have no strong feelings concerning this one, but given that AOU has adopted "Belcher's" as a name, I'll vote in favor of following them, i.e., "yes" on this proposal. Comments from Jaramillo: "YES Change to Belcher's Gull. An unattractive name, but one that does have benefits. I do like the idea of splits having brand new English names, and the retention of the old name to refer to the entire group/complex. So in this case we could use "band-tailed gulls" to refer to the two, and the patronyms Belcher's and Olrog's to refer to the individual components. Band-tailed Gull has a long history, but most of it pre-split, changing a name now to partially accommodate for the split seems perfectly reasonable to me Also note that the tail band is not diagnostic, second year Kelp Gulls have a nice black tail band often and are commonly misidentified as Belcher's Gulls because of undue importance given to the tail band in making the identification, hey if it's in the name it must be important. This is not a reason to change a name of course, I am just pointing it out to note that the feature is not really diagnostic." Comments from Zimmer: "I vote "YES", for reasons of symmetry, to avoid confusion with pre-split (broader) "Band-tailed Gull", and, because (as pointed out by Alvaro) the emphasis on the tail-band does cause birders to misidentify subadult Kelp Gulls with tail bands." Comments from Nores: "[YES] Si estoy de acuerdo de cambiar el nombre de Band-tailed Gull por Belcher´s Gull. El diseño de la cola de Larus belcheri es igual que el de Larus atlanticus y por lo tanto el nombre es de Band-tailed Gull es válido para las dos especies."
