BIRDS OP ARRAN. 307 



WIDGEON (Anas penelope). Common in winter. 



EIDER DUCK (Somateria mollissima). Rare; occasionally 

 finds its way into Kilbrannan Sound. 



VELVET SCOTER (Oidemia fusca). Very rarely seen. 



COMMON SCOTER (Oidemia nigra). Yery rarely seen. 



POCHARD or DUN BIRD (Fuligula ferina). Occasionally 

 met with in the lochs of Arran and Bute. 



SCAUP DUCK (Fuligula martta). Of less frequent occur- 

 rence than the preceding species. 



TUFTED DUCK (Fuligula cristata). Occasionally procured 

 in the lochs of Arran and Bute. 



GOLDEN-EYE (Fuligula clangula). Not unfrequent in 

 immature plumage. Old birds may be said to be rare in 

 the two chief islands. 



B/ED-BREASTED MERGANSER (Mergus serrator). I cannot 

 find any authentic instance of this bird having bred in either 

 Bute or Arran, though I have no doubt it is resident in the 

 last named island. 



GOOSANDER (Mergus merganser). This handsome bird is 

 yearly becoming more plentiful in the Firth of Clyde. 



RED-NECKED GREBE (Podiceps rubricollis). Uncommon. 



SCLAVONIAN GREBE (Podiceps cornutus). I have seen 

 pairs of this bird in calm days off Arran in the beginning of 

 summer. Specimens in full summer plumage have been 

 sent this year (1872) from the outer Hebrides. 



LITTLE GREBE (Podiceps minor). Common on all the 

 lochs, where it breeds. 



GREAT NORTHERN DIVER (Colymbus glacialis). This 

 large and handsome diver is frequently seen off Arran at the 

 end of spring. Some birds linger till the first week of June, 

 and are then in their brilliant breediug plumage. A most 

 beautiful specimen was shot off Carradale, in Kilbrannan 

 Sound, in the last week of May, 1872. 



BLACK-THROATED DIVER (Colymbus arcticus). The same 

 remarks apply to this as to the preceding species. I have 

 seen specimens caught as late as May 29th.
