Bonelli's Eagle is found in southern Europe and northern 

 Africa from Spain and Morocco eastwards to China, but has 

 not hitherto been recorded from southern Arabia. The wing 

 of the single specimen (stated to be a female) measures only 

 455 mm., which is small even for a male. Perhaps the bird 

 is wrongly sexed. The moult is almost completed, only two 

 oE the tail-feathers and two of the inner primaries on each 

 wino- remaiuing to be shed.

Only the male from Menakha seems to be fully adult, with 

 a bill bright yellow ; specimen " d" has the bill pale brown, 

 though the plumage appears to be the adult one ; the other 

 three birds are all in immature dress with black bills. 



The Arabian birds seem rather smaller than those from 

 Egypt. The wing of the adult Menakha male only measures 

 410 mm., while Hartert gives the average dimensions of the 

 Egyptian bird as 430-458, but in other respects the Arabian 

 birds resemble those from Egypt rather than the darker 

 M. parasitus of the Ethiopian region proper.
