Clare Island Survey — Aves. 20 31 



Harelda glacialis (Linn.). Long-tailed Duck. — Less regular winter visitor 

 than the foregoing ducks to Clew Bay, Achill, the Mullet, and Killala 

 Bay : is more frequent on the north coasts of Connaught and Ulster 

 than on the south coast, but it visits Dingle Bay and Kilkee. 



Though marine in its habits, it has been shot on Lough Corrib and 

 Lough Derg, and at Killarney. 



Somateria mollissima (Linn.). Eidei; Duck. — Has occurred on Achill 

 (R. B. Sheridan), and has been obtained a few times on the Mayo coast 

 ( Birds of Ireland, p. 212), also on the coasts or islands of Donegal. 

 Galway, and Kerry ; more frequent on the north coast. 



Somateria spectabilis (Linn.). King-Eider. — An immature male was shot by 

 J. B. Sheridan, on Achill, 12th December, IS92, and identified by the late 

 Dr. E. B. Sharpe. This is the only record from our west coast. 



Oedemia nigra (Linn.). Common Scoter. — Winter visitor to Achill, Clew Bay, 

 and Blacksod Bay, remaining on the latter sometimes until June. On 

 Killala Bay, where it is a regular winter visitor. Warren has shot Scoters 

 on 5th July, 1889, and 31st August, 1900. 



As this bird has bred in Ulster, its nest should be looked for in Mayo. 

 It is found as far south as Dingle Bay in winter, but is apparently more 

 common on the coasts of Ulster and Leinster. 



Oedemia perspicillata (Linn.). Surf Scoter. — An immature female was shot 

 at Dugort, Achill, by J. B. Sheridan, 25th October, 1890, and identified 

 by A. G. More. An adult male and female, now in the National Museum, 

 Dublin, were shot on Killala Bay by Robert Warren and the late 

 A. C. Kirkwood in the winter of 1896-1897. These are the only records 

 of this American species from the west of Ireland. 



Mergus merganser, Linn. Goosander. — 'Wallace, Belmullet, states that one 

 was shot, 3rd November, 1911. Good, Westport, says that he has seen a 

 few specimens on Lough Mask, but, except on the east coast of Kerry, the 

 Goosander seems to be very rare along the western shores of Ireland. 



Mergus serrator, Linn. Bed-bueasted Merganser. — Breeds numerously on 

 the great lakes of central Mayo, and some nest on Lough Carrowmore. Pike 

 recorded a nest on Achill Sound, and H. M. Wallis another at Burton 

 Port in Donegal, though few are found near salt water ; but in summer 

 Mergansers are seen among the islands up Clew Bay, and in winter Hocks 

 appear there and visit Achill Sound, Clare Island, Blacksod and Killala 

 Bays. On the latter Warren has seen in June a hundred or more, chiefly 

 immature, swimming in a pack, such as the late Major Trevelyan has 

 described on Lough Erne in August.
