I do not understand to what you are referring by "is hardly known and of little importance culturally".
Your statement is completely unrelated with the parent article. Contrary to what you say, the golden eagle is by far the best known species of eagle and the one with the greatest cultural importance.
The golden eagle (Aquila chrysaetos) is the species of eagle that has become the state symbol of the late Roman Republic and then of the Roman Empire.
Inspired by the Romans, during the last couple of millennia many other states have included the golden eagle in their heraldic symbols and several of them are still using it today.
Even much earlier than the Romans, at all Indo-European people the golden eagle had a special importance, being the bird used as a messenger by the God of the Sky, later known as Zeus in Greece and as Jupiter at the Romans. Already the Hittite texts from 3500 years ago have many references to the golden eagle.
The golden eagle is also the species that has been the most valued as a domesticated hunting bird in Central Asia.
The use of the "bald" eagle by USA has also been inspired by the Roman golden eagle, but the original species was replaced with a native American species. The golden eagles have survived in small pockets spread over a very large area from Western Europe to USA, so they were not representative for USA alone.
While the sea eagles, to which the American "bald" eagle also belongs, are bigger than the golden eagle, the golden eagle is stronger for its size and she is able to hunt bigger prey in proportion to its size. Only some jungle eagles, like the harpy eagle, are definitely stronger and able to carry heavier prey.
