The Black Eagle. 



Up to the time Gates wrote the second volame of the 

 ' Catalogue of the Birds^ Eggs in the British Museum' the 

 only existing account of the nesting of this fine Eagle was 

 that of Hume in ' Nests and Eggs of Indian Birds,' and it 

 is not quite certain that the eggs described by him are those 

 of this Eaglcw 



In the first place, the nests are described as having been 

 built on ledges on the faces of clifis, whereas all nests taken 

 since have, without exception, been found on trees ; again, 

 in one of these supposed Black Eagles^ nests there were 

 three eggs, but no one else has ever found more than two in 

 a nest, and very rarely more than one. The colour of — or 

 want of colour in — -the fourth single egg almost certainly 

 shows that it was not that of the Black Eagle, which lays 

 very richly-coloured eggs. Finally, the lining membrane 

 in the eggs described by Hume is paler and moi'e yellow 

 than in any of those since obtained. 



Probably the first authentic egg of the Black Eagle is
