Problems with ID

Adrian photographed this Wheatear on Thursday March 22nd at Badaan Farm - while AJ had it posing in front of him, I was also observing the same bird but from another location 100m away but from the right side and rear. A second Wheatear was on the ground close by, both were females. The one on the ground appeared to be Northern but this one remained unidentifiable from where I was however, it did show some characteristics of a pale throated Black-eared Ssp melanoleuca. The bird was very obliging staying on its little rock perch for some considerable time however it only ever presented both of us a single view, it did not turn around unfortunately, it flew while I was changing location to get better views so I missed seeing it in flight. Its stance did not indicate Isabelline O isabellina examples of which where also numerous around the farm and from the back it did not look like a Northern O oenanthe. Since AJ had it in his sights I stayed well back - I could wait to see AJ's photos before attempting any ID.
After he posted these images on Bird forum a lengthy discussion has developed over whether it is a female Isabelline O isabellina or Northern O oenanthe - We would be interested to hear other opinions as to species ID, personally I am still undecided but votes in mail favour an Isabelline most likely a male
