Hi Kevin

These seemed a lot smaller, or at least chunkier (shorter-winged and stout
body) than shearwaters. I tried to look for the M marking to make them some
sort of Prion but I just couldn't see enough detail.

I wondered about CDP but as I've never seen one I wouldn't stick my neck
out and try to identify anything as a diving-petrel. And storm-petrel don't
hang around in flocks, do they?

I think the closest I can get is "dumpy seabirds a long way away." I think
I need to go on another pelagic!
