Could anybody help me to identify a Tern I have trouble to recognise? Photos taken from very far off, on a windy overcast day. (Sorry for the lack of clarity.) Netherlands, August 20 2018, Island of Terschelling, Waddenzee side.
The Tern has short red legs (visible in some of the images) and perhaps a slight red base to its bill. Its size is quite small, compared to Common Gulls in the background and Black-headed Gull left.
Confusing me is the light tip of the bill. Its small size and red legs seem to rule out Sandwich though.
Common is very likely of course, but do light tipped bill and strange (very long, unequally extending) shape of its primaries (way longer than tail it seems) fit Common? I'm equally hesitant about Artic (short apparent tail fits Artic even less).
Regards, Frank
