Distribution in the British Islands. — A Rare Visitor. It has 

 possibly occurred three times : — an adult, Mayfield, Sussex, 

 Jan. 1845 ; an immature, Orford, Suffolk, Oct. 1867 ; and 

 an immature from Thetford "VVarren, Norfolk, spring of 

 1883, which is doubtfully authentic. An immature Falcon 

 killed at Hatfield Broad Oak, Essex, Dec. 1901, and referred 

 to this species, was undoubtedly a dark female Peregrine. 



General Distribution. — The Gyr-Faloon breeds in northern 

 Scandinavia, Lapland, and northern Russia, extending west-

 elsewhere.
