One good Tern ... Where's the other?

Good weather persists.
From the sublime to the cor blimey.
Yesterday ...1/2doz shots around the camp-site.
Today ...200+ ranging from an intact limekiln on site, through pointy-shooty, touroid shots from the top deck of an open-topped bus touring "The English Riviera'' and ''four-eyed'' fish I correctly named as Anableps. (Nobody loves a smart-arse).
We still had time/energy to go through ''Living Coasts'' where, of all the exhibits (Including Penguins) these chaps caught our eyes.
I thought of a negativised Hercules Poirot and wondered what Pomade he uses?

BTW it's an Inca Tern. The rest of it was so unprepossessing and I didn't get a clear shot in flight.
