292 BRITISH BIRDS. [vol. xv. 



Great Skua {Stercorarms s. sktta). 



On September 22nd a Great Skua was seen by Mr. A. H. 

 Macpherson to attack a Black-headed Gull at Cley, which 

 after rising to a considerable height disgorged its food into- 

 the sea, where the Skua quickty followed it. There has been 

 a good deal of confusion about this bird, and some of the 

 Norfolk records — e.g., Cromer, July 1872 — are hardly to be 

 trusted. 



Black Grouse {Lyrurus tetrix). 



Two handsome hybrids between this species and the 

 Pheasant were shot, as I learn from Mr. H. S. Gladstone, at 

 Hunstanton Hall in November, the Grey-hen parent having 

 been the produce of some imported eggs. As far back as 1866 

 Stevenson mentions Black Grouse as being occasionally shot 

 on this estate, and both here and at Sandringham there is 

 ground which is not unsuited to their habits, yet it would 

 be too much to believe that any descendants of the native 

 race still exist.
