BROOKLYN - The MTA was not pleased to see fake advisories popping up at some of the city's subway stops. 

Fans of the "Lord of the Rings" posted signs informing commuters of "great eagles" and other supernatural creatures flying between stops. 

The notices coincide with May 1, which is a significant date in the popular fantasy series. 

An MTA spokesperson said in a statement, "If someone's idea of a cute sign has the potential to confuse even a single one of the MTA's almost 6 million subway riders, then we're going to take it down as fast as we can find it."
