The then-wife and I had only been "verbally" abused while walking
in the same area.
A neighbor said he used to have a tree abutting the driveway.
Grackles/Starlings would nest, doodooing up his car, so he
bought a bag of Brazilian nuts or the like, and a slingshot. The
nut was big enough to carom off the branches, encouraging
the flock to leave en mass.
A Wrist Rocket. One of the best personal weapons a home owner in a residential area can own.
Redwing Blackbird: Native species, usually benign. Lives in and near marshland. Good insect eater. Leave alone unless they need “incentive to relocate”.
Starling: invasive alien species: KILL if possible, otherwise drive away by any means possible. Eat native birds’ young, grain, and anything you don’t want them to. Did I mention KILL THEM if you can?
