Lanzarote shearwaters - all Cory's? (1 Viewer)

Hi - took these at some distance on the west coast of Lanzarote and thought at first they were all Cory's. But looking more closely I wonder if they are? Checked with a local birder who confirmed Cory's for all, but would appreciate a second opinion. Many thanks.

Can you say what you're seeing that makes you doubt they're Cory's? They all look like Cory's to me.

Thanks Andrew - mainly inexperience! The dark head patches on 5, 6 and 8 made me wonder but it's the first time I've ever seen Cory's and I'm not familiar with the variations.
