Apparently its the sound of high air pressure that moves the nozzle actuators when the pilot moves the throttles and changes the position of the nozzles..
I always thought it was like a hydraulic sound in the nozzles, but its actually the sound of air pressure that moves the nozzles.
Hope that settles it! If you want to look it up its called 'CENC' or 'Convergent Exhaust Nozzle Control'
CHIRP... CHIRP CHIRP... CHIRP
Now that's a pretty majestic chirping bird :)

Yes, this is the most interesting sound in aviation to me.
I heard first in Kecskemét last summer by the F-15A/C at landing, but in Lakenheath this sound happened when the E model switched the afterburner.
Strange P&W sound.

Awesome video, I lived at RAF Lakenheath for 3 years from 2001-2004 and still to this day don't know what that sound is lol.
