Spotted v swamp harrier

["Philip Veerman" <>]

Perhaps you could start by telling us which books you have access to. I 
wouldn't want to go to the bother of retyping what is well shown and set out in 
the standard field guides.

Apart from the obvious colours of an adult Spotted Harrier and white rump of 
the adult Swamp Harrier, juveniles can be difficult. However these are other 
comparative features: the Spotted Harrier always is heavily barred on main 
flight feathers and the Swamp Harrier is much less so. The Spotted Harrier 
always has spots on the wrist area of the upperwing and the Swamp Harrier never 
does.
