1910. Campbell. — Birds of Inch and Zipper Lough Swilly^ 27 



the island. The Great Black-back frequents Inch during the 

 shooting season to prey upon the wounded birds, but I never 

 knew of it to remain, except on this occasion, during the 

 breeding season. It was interesting to find a nest on a low 

 sandbank, surrounded by fresh water, and some seventeen 

 miles from the open sea. The Lesser Black-backed Gull {L- 

 fiisais^ Linn.) is common, so is the Herring Gull {L. argejit- 

 atiis, Gmelin). On 24th May, 1897, I saw a Lesser Black- 

 backed Gull diving into the waves from some height, just 

 like a Gannet. I have a note of a Herring Gull living in semi- 

 captivity for 27 years. It went off for some time every year in 

 the breeding season, but always returned when the impor- 

 tant duties of this time were over. The bird is still living. 



The Common Gull {L. camis, Linn.) is fairl}^ common. On 

 17th January, 1892, I saw a Common Gull dive down and 

 pick a large living eel (about 14 inches long) from the water 

 near the shore. It carried it some way in its bill, and tried 

 to swallow it, but failed. However, it held on to its capture. 

 An immature Herring Gull took in the situation from some 

 distance, and coming up, seized the eel from the other bird, 

 and carried it off. 



I have one reported record of the Glaucous Gull {L. glaucus 

 Fabricius). On 3rd November, 1896. Constable Johnston, 

 R.I.C., told me of his sergeant shooting a large gull at Lins- 

 fort, Lough Swilly, which he sent through a friend to the 

 Glasgow Museum. He got a letter from the Museum saying 

 it was a Glaucous Gull. The Kittiwake (Rissa tridactyla, 

 Linn.) is fairly common, and comes up the lough as far as 

 Rathmullan. 



The Arctic Skua {Stercorarius. cnpidattis, Gmelin) has been 

 seen at Inch by Dr. H. Leebody, and by Mr. H. Williams on 

 9th September, 1892. The Razor-bill {Alca torda, Linn.) and 

 Guillemot {C/ria hoik, Linn ) are common. The Black Guille- 

 mot {U. grylle, Linn.) is not common in the lough. The 

 Puffin (Fratercula ardica, Linn.) is fairly common on Lough 

 Swilly. 



The Great Northern Diver {Coly7nd7is g/ada/is,Lmn.) is a fairl}^ 

 common winter visitor. Of the Black-throated Diver (C 

 ardicus, Linn.) I have one record. Dr. Henry shot a mature 

 bird on 7th November, 1892. 



The Red-throated Diver (C septe^itrioiialis, Linn.) is com- 

 mon in winter, and has been seen once by Dr. Leebody and
