256 THE ORNITHOLOGY OF BERWICKSHIRE. 



Of the Laridse, or Gull family, there appears to be only one we can 

 properly designate a permanent resident, viz. the Larus ridibundus, 

 black-headed gull. Within our district this species has several breed- 

 ing stations, the principal of which are the pieces of water at Pallins- 

 burn, Paston, and Dunse Castle. Six species appear as periodical sum- 

 mer visitants, four of which belong to the Terns, a genus distinguished 

 from the gulls by their swallow-like form and a more rapid and power- 

 ful flight ; the other two are the herring-gull (Larus araentottusj y and 

 lesser black-backed gull (L.fuscus), the first breeding in great numbers 

 in the sea-cliffs. There is also one periodical winter visitant, the com- 

 mon gull (L. canus) y and five occasional visitants, among which are the 

 two large white-winged gulls (L. glaucus and L. islandicus), and the 

 Lestris Richardsonii y arctic skua, better known, perhaps, by the name 

 of the dung teazer.
