My guess is also, that it has been very warm or even hot in many parts of
Africa in recent days (is nearly 100c above average?) What with the dust
plume that Martin mentioned, this must have had a significant impact on
movement.

I've not seen anything of them. I doubt that they would have come here
knowing that the warm wet weather would be provident. It is more likely
that they were forced to move early by the conditions in Africa. However
it appears that they could just have been so well fed by all that
cyclonic stuff they are getting over there, that they were ready early.

They tend to migrate in flocks made up of similar generations if I
remember correctly. Perhaps these birds are first broods? I presume they
breed in both countries?
