THE LARGEST BIRDS THAT FLY 333 



tained in the month of August, weighed 9J lb., and 

 measured between the extended wings 6 feet 7 in. 

 Another two-year-old bird, procured in Ross-shire 

 in September 1897, weighed 11 lb. ; a third, killed 

 at Kylemore Castle, Gal way, in October 1889, 

 weighed 12J lb. An immature White-tailed or Sea 

 Eagle, shot at Brighton, weighed 10 lb. ; another, 

 killed at Arundel, barely 10 lb. ; while a fine old 

 bird in fully adult plumage, from Stornoway, Lewis, 

 weighed no less than 162- lb. This is the heaviest 

 White-tailed Eagle of which I have any note. It 

 has been referred to by Robert Gray {Birds of the 

 West of Scotland, p. 17) as being in the collection of 

 Sir James Matheson, Bart., of Stornoway, and the 

 finest British example of the Sea Eagle he had 

 ever seen. He adds, " compared with three or four 

 other Sea Eagles in the same collection, its size, 

 indeed, appears quite extraordinary, and had the 

 specimen been darker in colour it might have 

 readily been mistaken for the Northern Sea Eagle 

 of Pallas." 



It might be supposed that the Imperial Eagle 

 would be larger and heavier than the Golden Eagle, 

 but from actual comparison this does not appear to be 

 so. Thus the Golden Eagle measures 3 feet to 3 feet 

 4 in. in length, 6 feet 6 in. to 7 feet 6 in. in expanse 

 of wing, and weighs from 9 lb. to 12 lb., while the 

 Imperial Eagle measures only 2 feet 6 in. to 3 feet in 

 length, 6 feet 4 in. to 7 feet i in. in expanse of wing, 

 and weighs on an average from 6 lb. to SJ lb. 



As for the Lammergeier, it will be found on 

 comparison of measurements and weights, that
