AQUILA CHEYSAETUS (L.) 

 Golden Eagle. 



A very rare casual visitant. 



The instances of the visits of this noble species to any part 

 of England being extremely rare, as evidenced by its absence 

 from most county lists, Yorkshire would seem to have been 

 favoured by them to an unusual degree, no less than six 

 instances of its occurrence within the limits of the county being 

 recorded ; chiefly during the winter months. 



From the fact that the White-tailed Eagle in the dark plumage 

 of immaturity has been so frequently confounded with the present 

 species, the writer has made the most careful enquiries as to the 

 identification of the following, and many other supposed 

 occurrences which were communicated.
