I know very well that what I am going to say will bring controversy but I firmly believe that all the names of birds that contain the word "common" should be replaced since that term is derogatory.
There is no doubt that the term is used to emphasize that the species is ordinary and of little value due to its abundance, despite other approaches that associate it with the land.
Common chaffinch, common redpoll, common reed bunting, common linnet, common yellowthroat, common nightingale, common redstart, common whitethroat, common kestrel...
We are often resistant to change and we don’t realize that change itself is constant. Changes trigger progress. Things move forward and develop because of them.
What you've posted isn't really controversial at all. What it is, though, is that it is very narrowly selective. Why do I suggest that? Just take a look at this typical dictionary entry:

My understanding is that the use of the modifier 'common' in ornithology and birding is limited to the meaning of the adjective as defined in my blue text in Section 1, which covers the principal usages.
If I read your post correctly, you consider all uses of the modifier 'common' in ornithology and birding to be limited to the meaning of Section 3, which covers a usage, a British idiom, that is far from major, and that all the rest of the ornithological world has to do is agree with you...
I agree that this British idiom is clearly based on snobbery and condescension, but that idiom has never been widespread in ornithological usage, if indeed it was ever intended that way.
