I'm convinced corvids recognise a gun. If I'm on my regular daily checks I'll always have hmr or recently 12bore semi. If see corvid in range, then they wait until I stop quad then soon as I start to move they're off. Yesterday, out to check water pipe, (no gun) had a crow basically shadow me the whole time! I stopped...got off bike...even held up pretend gun....not bothered!! Proper sods law.
