Oddly enough, within town, they're remarkably tame. Maybe with enough humans around, they learn that we're not a threat, and it's costly to evade a non threat. Likewise the turkeys. My daily bike commute goes past a public golf course, and there's usually a pair of cranes there, sometimes with little ones. They ignore me.
I suspect that depends on the nesting status. Long ago I worked in an office building where a mated pair would frequently raise their chicks outside the front door, and before the eggs hatched they would aggressively harass anyone walking to the building.
