Petrels & autumn

I'd call all 3 of those pics as Wilson's Petrels. Are the bottom 2 are the same bird?

Feel free to follow me around Derek, but from 3-9 October I'll be in Cornwall and Ellie may get a tad miffed if you appear at the breakfast table! But if I do find something (in Pembs or Cornwall), you and everyone else will know straight away.
