Probable Slaty-backed Gull on January 1st pelagic

Well, I’ve done it now.


I’ve convinced myself that a 2nd cycle gull I photographed offshore on the pelagic trip from San Diego is a Slaty-backed Gull. Or, perhaps it is a Slaty-backed x Herring, but how would one tell?


Perhaps others have photos of it too. I was trying to show a 1st cycle Herring Gull to other passengers, but this odd bird kept getting in my way….


9 photos and descriptions are added to the eBird trip list as “Larus (sp.)” which is true even if I botched the more specific ID.
