Bernie ,
Yes even at over 100 m, the crane was very aware of my distant presence .
It kept on turning and checking on me - frequently . I was tempted to get closer - but I would have been tresspassing on private property - a nono.
The last time I was in the vicinity an OPP cruiser quickly arrived ( cherries flashing) out of nowhere to politely check me out. My binos / birding explanation cleared me.
Thanks for your comment .
Jim
