I don't want to be too picky, but at least the eagle pictured on Germany is kind of wrong. While it is not specified which species of eagle the "Bundesadler" is, it is most definitely never depicted as a bald eagle (that would be the USA). More usuale would be a Golden eagle or a White-tailed eagle.
If you are interested in the history and background of the Bundesadler, here is an informative video. It's in German and I'm afraid there is no English version
I always find it weird when countries use animals that are not native to their country. Although in Scotland I'm pretty sure that unicorns actually exist somewhere. Or at least, they do if you drink enough.
I was in a bar the other night and overheard three very hefty women talking. Their accent appeared to be Scottish, so I approached and asked, "Hello, ladies, are you three lassies from Scotland? One of them angrily screeched, "It's Wales, you bloody idiot, Wales!" So I apologized and replied, "I am so sorry. Are you three whales from Scotland?"
Team unicorn, represent! I'd swear half the entrance doorways to our historic buildings have the lion and the unicorn carved above, and everyone still seems surprised by the "Scotland's national animal is a what now?" response.
E.g. Denmark even has 3 national animals listed and not just the swan in the picture: Red squirrel (national mammal), Mute swan (national bird) and Small tortoiseshell (national butterfly).
Unfortunately Italy does not have an official national animal, meaning no animals are enshrined in our constitution or any of our national symbols. However if we had one that would definitely be the wolf.
Probably Wikipedia but it's bullshit, it's based off a couple of random websites that make the claim with no basis. There's no animal being used as a national symbol in Romania.
The closest thing are the animals that appear on the coat of arms (eagle, bull, lion, dolphin) but the coat of arms is the national symbol not the animals. Otherwise you could say that the moon and walls are also symbols of Romania because they're also on there.
