Thanks Philip. HANZAB isn’t all that clear on this age of harrier.

Hi
David,
Certainly is a Spotted Harrier. If not a fully adult, then a close to
adult. Very strongly barred pattern on wings are enough to be sure of that.
Stephen Debus' book has all you would want to know about ID of these things.

Philip’s reply about juvenile harrier rump colour has got me thinking about
a photo I took recently near Cameron Corner, in north-east South Australia. It
is of a harrier, and obviously a young one, but because it has a dark rump I
have identified it (probably mis-identified) as a Spotted Harrier. I think I
have always assumed that pale rump = Swamp Harrier and dark rump = Spotted
Harrier.
It troubled me at the time because of the dark rump, and because I thought
it looked more like a Swamp Harrier. What do you think?

Yes
Dennis is right. Although juvenile Swamp Harriers don't have a white rump, so
that is not of itself diagnostic but in combination with that juvenile Swamp
Harriers are very dark, it is. Even though the photo isn't clear, the easily
seen amount of spotting and bars in the wing and tail make it sure to be a
Spotted Harrier. Also Spotted Harrier is more slender than Swamp Harrier, which
the photo fits. I would expect more Spotted Harriers than Swamp Harriers out
Harden way.
Philip
It is a Spotted Harrier. No white rump, which rules out the
Swamp Harrier. Long legs, spotted plumage, Strong brown colour all fit
Spotted Harrier. See photo here
