KITTIWAKE. 249 



It is frequently seen inland in spring, following the 

 courses of the rivers, and Mr. James Garnett of Clitheroe 

 ssijs that it invariably, and in pairs, comes up theEibble 

 in April and May, when the young salmon are making 

 for the sea. Stragglers, especially after stormy weather, 

 have been seen everywhere, and in winter it is more 

 or less numerous all along the shore, being generally in 

 company with the Common and Black-Headed Gulls. 



GENUS LARUS. 



GLAUCOUS GULL. 



Larus glaucus, 0. Fabricius. 



Occasionally seen in winter, but very rarely. The late 

 Mr. H. Durnford stated {ZooL, 1874) that he picked 

 up an immature bird, with a broken wing, on the 

 Formby shore, on November 8, 1873. 



HERRING-GULL. 

 Larus argentatus, J. F. Gmelin. 



Local Name — Silrci--hack. 



The Herring-Gull is found on the coast, and occurs 

 in flocks, especially about Walney Island, the year 

 through, but does not nest in the county. It is occasion- 

 ally seen following the courses of the rivers, and is shot 

 at rare intervals on the inland reservoirs. Mature birds 

 are uncommon.
