The 'doves' are seagulls!! Or 'Sh!te hawks' as we call them here LOL!!
The island with all the monks buried is Iona. It's just off the Isle of Mull and you get the ferry there from Oban.
Unfortunately, the animal park you refer to (Oban Rare Breeds) has now closed down. It is greatly missed. We went every year around Spring to see all the new babies.
I think you'd hardly recognise Oban anymore it has changed so much in the past 20 years. Although McCaig's tower is still there!
I know it is difficult bringing dogs to UK. I would like to take my bitch to the continent but this year left it too late for her Pet Passport.
If you do make it to Scotland you must let me know and come and visit.
