The adult female is nearly the same in colouring as the 

 male, but larger in size, exceeding him by about an inch and 

 a half in length. 



The young birds have the legs paler in colour ; the cere 

 and orbits almost white, sometimes intermixed with blue ; 

 the head, neck, and all the upper parts are dusky, with rust 

 coloured and yellowish edges. 



The egg figured 9 in the plate is that of the Hobby. 

 Some of the eggs of this species, as described by Montagu, 

 are bluish white, with olive srreen or yellowish brown blotches.
