NOTES ON THE TWO SPOTTED EAGLES INHABITING 

 THE EUROPEAN CONTINENT. 



J. H. GURNEY, F.Z.S., 



Northrepfis, Norzuich; Member of the British Ornithologists' Union; Author of 

 i A List of the Diurnal Birds of Prey etc. 



The European Spotted Eagles (so called from the conspicuous white 

 spots which the upper portion of their plumage exhibits whilst they are 

 in immature dress) are divisible into two races or subspecies, for which 

 I adopt the names used by Mr. Dresser in his ' History of the Birds 

 of Europe' — viz., for the larger race that of Aquila clanga Pallas, 

 and for the smaller that of Aquila po?narina Brehm. 



Mr. Dresser (op. cit., vol. 5, p. 500) gives the following wing 

 measurements of A. clanga, viz. : — 



Males ... ... ... 19*50 in. to 21*30 in. 



Females ... ... 21-0 in. to 21*80 in. 



Of A. pomarina he gives the measurements of but one specimen, 

 an adult male from Danzig, with a wing measurement of 1770 in. 



Mr. Seebohm in his ' History of British Birds,' vol. 1, p. 106, 

 records the corresponding measurements of several additional 

 specimens of both races, with the following results: — 

 AQUILA CLANGA. 

 19 Males ... ... 20*o in. to 21*50 in. 



9 Females ... ... 21*0 in. to 22*0 in. 



AQUILA POMARINA. 

 16 Males ... ... 18*0 in. to 20*0 in. 



10 Females ... ... 19*0 in. to 21-0 in. 



The following wing, measurements have been taken by myself 

 from specimens in the Norwich Museum : —
