Observasjonsdetaljer
Ad Caspian-ish Gull present 10.48-10.54 when flew west. Mantle darker than Herring, head unstreaked, dark eye, skinny bill with no obvious gonydeal angle. Primary pattern seemingly out of range of pure cachinnans though with a near complete band on p10 which was extensively black and only a small white patch on p9. Smaller than the Herring and presumably a female.
