Hi Simon
An interesting discovery whatever they are. Well done!
I have seen large nos. of Arabian (we used to call them Persian) Shearwaters in
Oman (Mirbat) and small nos in the UAE when I lived there. There do look good
for Arabian (which I think have also been recorded off Sri Lanka and India?)
but I remember a much darker underwing than this (more like a Hutton's
underwing). Have a look at some of Jans Erikens shots from Mirbat):

This could be moult / wear or the light / photos from you trip? Also I don't
remember the eye looking so prominent (almost Little like) although Arabian can
almost look like it has a poorly defined pale supercilium.
I've seen Audubon's on the Seychelles (I think this is now 'Tropical') and
their upper parts are a sooty black colour - but the white sides of the rump
are not always an obvious feature. In essence Arabian and Tropical (the forms I
have seen in the Indian Ocean) are like comparing a Balearic and Manx
Shearwater - colouration wise (this will mean more to Poms who grew up sea
watching off Cornwall!). These birds don't look like Tropicals I've seen in the
Indian Ocean.
This probably doesn't help much............!
