Slight wind and no gusts? Sound like vortex shedding. It is not uncommon with tubular mast like structures. But in the worst case if the shedding frequency matches the poles own natural frequency it can start amplifying the deflection until the strucrure fails.

That’s the seagull perched on top before I got the phone out. He’s was sitting there for ages 😆
