I for one would leave them be if I came across them in MF. Mind you, in my interactions with this species I have yet to see one fly on approach, even close approach, all the ones I have dealt with have either done a stately slow walk away and/or then
just sit down. For those who have not seen it - a film by me of a typical experience of this bird

No, for best 'effect' you just need some young kid out for a walk to run among the 'birdies'. Hence my comment about public education, not just bird watchers.
