Surely the intent would be to not sound like a Bulgarian bird, so that when you next have to revert to this system Iliana will realise it's you and not just think 'oh, it's a bird'.... But then you're in Norway not Bulgaria so maybe it's more important to not sound like a Norwegian bird... but worth taking into account that there is probably more overlap between possible Bulgarian birds and possible Norwegian birds... or maybe not, what with the acclimatisation societies and all that.... I should probably stop before I get you anywhere near as confused as I'm getting myself...
I think it's safe to say my bird call sounds neither like any Norwegian bird, nor Bulgarian. Or any bird really. Except for maybe a cockatoo...those things can be noisy and tuneless AF.
Naw, now I miss Canberra and my uninvited 5am wake up calls.
