Birds from France (1 Viewer)

I just got back from two weeks in Brittany and have a few birds I'm not sure of. Birds 'a' and 'b' were taken from the ferry from Plymouth to Roscoff when we were fairly close to Roscoff. Bird 'c' was taken on a boat trip to the Sept Iles Nature Reserve. I think c is Manx Shearwater or 'Puffin des Anglais) and a is some type of shearwater but I'm not sure which.

Here's c...

Pics 1-3 IMO show Sooty Shearwater.( The only other dark Shear is Balearic in these waters.) And have discounted "dark/poor capture" by elongated rear end, as opposed to shorter, with feet projecting, on a BS. Also, general overall structure, long wings and, in pic 3? That light section evident on left wing where primaries meet secondaries.
"C" is a Balearic Shear.
The other 2 photos? I get the impression of 2CYR Gannet?
Though of course I could be the wrongest person ever! But I think I might be a bit right in some of this...:cat:

Thanks very much Phil. I'd guessed at sooty shearwater for the first but have no experience of them. I was also thinking of gannet for the second - there were lots of them about. The third one, the guide on the Sept Iles tour told me it was a 'Puffin des Anglais' which translates as a Manx Shearwater but again I have virtually no experience of sea birds. Can I put this down as a Balearic then? That and the sooty are firsts for me.

Bird C is quite clearly a Balearic Shearwater ( which is relatively common along the coasts of Brittany, especially at this time of the year). I can make out very little on the 3 photos for bird A but, IMHO, these also look more like Balearic rather than Sooty (quite scarce except under ideal weather conditions here). Bird B seem to be a Gannet as Phil has suggested. The further west you go along the north coast the more scarce Manx becomes and on the west coast of France, where Balearic is the default small shearwater species, we get quite excited about seeing a Manxie !
