I am new to this forum and would like to say that this realy is a magnificent place to visit when wanting advice on birdtrips around Europe!
I am fortunate enough to travel to the Azores Islands this summer for 2 weeks during June. I was hoping that people here new of some places there that were good for bird photography.
I don't remember any fellows from the Azores. However you might be interested in the Surfbirds.com trip report sites where detailed infos could be found about the best sites. Note, they are the worth-to-visit birding sites which not necessarily the best photography sites.
