Sandwich Tern – 1894

Sterna cantiaca

Although this species is not included in any of the lists, we feel certain that it must occasionally visit the Pembrokeshire coasts, the Milford Haven estuary, the neighbourhoods of Tenby, Fishguard, &c. But we must at the same time state that it is very rarely seen off the North Devon coast.
