Not really sure what the appropriate name is for this species as there seems to be some debate from this location.
No interactions present.
Yes, I am confused over what subspecies this should be. Collins Guide says koenigi for the Canary Islands, and shows meridionalis with a clear, thin white supercilium, which this bird lacks. But I have seen other sites say that Canary Islands birds are meridionalis. It all goes to prove that there is much to be sorted out within the Great Grey taxonomy.
Great pictures, whatever it is!
My Flickr photos...
Harris and Franklin Shrikes and Bush-Shrikes Helm 2000 p156 have the Canary Island subspecies as koenigi. Though they do devote almost the entire introduction to the difficulties of taxonomy.
