frequently seen and taken the nest on Osey Island, in the parish of 

 Steeple, on Ramsay Island, and at Paglesham. His cousin, Mr. Robert 

 Laver, has shot the old bird from the nest, which is generally that of 

 the Carrion-Crow." Dr. Bree has since written to say that the trees in 

 which the Hooded Crow used to breed have been cut down in one of the 

 localities whence he kindly endeavoured to obtain specimens. 



Messrs. Gurney and Fisher mention a pair having once nested near 

 King's Lynn in 1816. 



There is reason to believe that the Hooded Crow breeds occasionally 

 in North Wales, where the birds have been noticed so late as May. 

 Further information on this point is very desirable. 



The Hooded Crow has been known to breed near Scarborough 

 on two or three occasions (Yarrell, and 'Zoologist,' p. 6142). A 

 bird which bred at Hackness is still preserved in the Museum at 

 Scarborough. 



Mr. Selby marks the Hooded Crow as breeding occasionally in 

 Northumberland ; and Mr. J. F. Crellin reports it as breeding annually 

 in the Isle of Man. The bird breeds throughout Scotland, becoming 

 more abundant northwards. 



In the neighbourhood of Glasgow, Mr. JR. Gray describes the 

 Hooded Crow as constantly pairing with the Carrion-Crow, and says 

 this is the rule rather than the exception ; and in Rennie's ' Field 

 Naturalist' (1833, p. 279) Mr. Blyth records that the same observation 

 has been made near Inverness. This circumstance is greatly in favour 

 of the opinion that the two birds are races of the same species, 



Blasius treats the Hooded Crow as variety /3 of C. corone.
