Common they well be, but I'm an admirer of this whole family of clever, characterful birds.
Common they maybe where you come from but I've never seen one here, in this part of Perthshire.
I too am very fond of this family of birds lordro. They can certainly hold a mirror up to themselves! They remind me of when I lived on the Pembrokeshire coast and a pair used to hunt right next to my cottage - although I'm not very knowledgeable about birds, I now instantly recognise their call. Sorry to hear about the lack of magpies in your part of Perthshire Bill!
Just a wee note on why I eventually used the common name "Eurasian Magpie". Although it's not required, I try to use unique common name for all the species I find (in case, for example, I take a photo of a magpie in the States or a magpie in Australia, both of which are viewed as different species - not by all for the US one I admit). It's fairly important for me to do that as I maintain a database of the species I've seen and it's good to have the common name as a unique field as well as the Latin name.
I would have changed the identification to reflect the common name, but by the time I had decided on which one to use, so many people had agreed with the original identification that it wouldn't have made any difference. The next time, if I try to identify a species myself, I'll work out what common name I am going to use beforehand, rather than just accept the suggested one without thinking about it. Ah, the trials of being interested in nature...
