Shearwater - Tenerife (1 Viewer)

Hello

Just returned after a trip to Tenerife.. Saw this Shearwater, but doesn't feel comfortable to come with a sure ID.. Guess it's a Scopoli's shearwater .. But my book divides between Calonectris diomedea borealis and Calonectris d. diomedea.. Can't see much difference between these two anyway?

Can anyone help?

A Cory's-type shearwater. Taking it any further seems (check The Book) to be difficult, dodgy and subject to much individual variation. It seems that the (large) amount of dark on the outer primaries favours regular Cory's shearwater. Perhaps.

It’s a Cory’s shearwater, C.d.borealis for two reasons;
1) undersides of the primaries (wingtips) are solidly dark
2) Cory’s is an abundant breeding species in the Canaries whereas Scopoli’s breeds in the Mediterranean and is an uncommon visitor to the Canaries (although hard to identify so i’m sure a lot get missed)
Cheers
James
