I believe you both to be right – and wrong. The common name is Black-billed Magpie (though Collins 2nd Edition does use common) according to Madge S. & Burn H. Crows and Jays Helm confirmed in Birds of the World Recommended English Names presumably to differentiate it from the Yellow-billed Magpie (scarce US species). However Madge & Burn recognise 13 subspecies with our bird being P. p. pica.
However taxonomy seems to be changing almost by the second these days so I’m quite prepared to stand corrected.
I agree, only changed the latin name to get other observations up. Ispot picked the english name. Seems to get more confusing every day.
I'm sure there must be other popular names -
What is it called in Welsh, for example?

Some say it's time to throw the textbook understanding of lichens out the window.
