Every European (and I guess non-Europeans as well) can vote what our next Euro design will be: https://surveys.ecb.europa.eu/10b/neweuro/
About ten different designs are available and about half of them feature birds instead of boring people.
I really like the bird designs as they symbolise freedom without borders. Hope one of them gets chosen in the end.
Yes, I saw someone on Mastodon say that birds have less and less habitat under the EU and that the notes are becoming the safest place for them at the moment .
