Characters. Apart from the differences in structure recorded 

 above, the male can be easily told by the varying gloss on the 

 head, and the large patch of white on the sides of the face. 

 The female has the head and neck greyish-brown, with a white 

 spot on the ear-coverts and a white wing-speculum.
