CROWS OR SOMETHING DIFFERENT
Can we get something different at night other than crows? Owls being spooked out of trees perhaps? Feral Cats hissing? **** i'd settle for a pile of snakes over having to avoid another murder of crows.
Owls: Only at night. They sit in trees and, like the current crows, can be spooked by hunters passing under them or making noise near them.
Cats: Night and Day. Sitting under houses? On fences? mostly found near compounds they hiss (or whatever) when disturbed
