Same place, same day, but very four different birds. Here are some Herring Gulls from Peterhead yesterdy. Above (right) is an odd, petite bird, especially a small and pointed bill. In flight (see the two images below) it showed very silvery and contrasting inner primaries. It has retained juv scapulars and an odd tertial pattern.
A very pale bird, but combined with a rather extensively dark tail and well barred rump . Pale panel in the greater coverts scared me for a moment (ie. you never know, we might get a 1w Slaty-backed Gull one day) , but actually these coverts are rather well patterned and simply worn/faded (rather than being the uniform panel seen on SBG).
Its tail and upper tail coverts are nothing to get excited about.
