If you're not counting birds that aren't breeding, I wonder about your geese, duck- and waderlists!
Eurasian Scops Owl must be one of the easiest owls to see anywhere in its range. I wonder where in Spain you are, that you have a hard time connecting with this one...?
That's a really funny idea. I have seen from up close and in great detail Arabian, Africa, Pallid and Collared Scops Owl, easy peasy lemon squeazy. I have heard countless Eurasian Scops Owl across several countries (including the Czech Republic!) and all I ever saw was a distant flying smudge.
