Interesting, around here raptors hunt high, and if prey falls to the ground they abandon it; too dangerous to go down in the streets.
That's a hawk vs falcon hunting difference, not a city vs countryside one.
Quail won't take off if a falcon's shadow passes over them; they'll burst if a hawk's does.
I almost ran one over turning in a car park in Edmonton. Backed up and it was still standing on the pigeon glaring at me. I drove around.
