So, the ECB has opened this survey to get an idea if people would like to see birds on the next set of Euro bank notes.

Okay. My phrasing might be a bit leading as there are other topics they present as options to thumb down before they ask about the birds (like European virtues and culture expressed as hands). But really, in the end... they just want your OK to put birds on bank notes.
If you have some time for this: lend them a hand!

Survey on Euro Banknote Themes

@nblr I will laugh if a sandpiper ends up on any of the bills. More so if it is not the 100 euro one. (100 guilder bills had them and where hence nicknamed "snip" a name still sometimes used for the 100 euro bill)
