THE ARCTIC TERN. 
STERNA MACRURA, Naumann. 
This northern representative of the preceding species appears to 
be the only Tern that nests in the Shetlands, while southward it 
decidedly predominates over the Common Tern in the Orkneys, 
the Outer Hebrides, and along the west coast of Scotland to the 
Isle of Skye. On the east side of Great Britain it breeds in 
several localities down to the Farne Islands, south of which it is 
only known on passage. In the west of England it nests on Walney 
Island, where, however, the Common Tern outnumbers it ; and the 
same must now be said of the Scilly Islands, on which, according to 
Rodd, the Arctic Tern was formerly in the ascendant. In Ireland 
it breeds on islands off the coast, from Wexford to Antrim, and 
more plentifully in cos. Donegal, Mayo, Galway, Kerry and Cork. 
On migration it is found on all our shores, but rarely inland. 
Beyond the British Islands the Arctic Tern occurs in abundance 
—during the short summer of the northern regions—as far as human 
foot has trod ; for Col. Feilden, when with H.M.S. ‘ Alert,’ obtained 
it above lat. 82° N., and Parry’s Expedition observed it beyond 
Spitsbergen, while it has been recorded from Franz Josef Land. In 
Asia, as well as in America, it is completely circumpolar in its range.
