Fish hawks are squirrel hawks too! Never knew. My brother lived in Katy and had some nice oaks in his back yard and a couple of bird feeders. His method was a pellet rifle. One year he got like 250 or some number like that.

Really cool!

one way to keep any kind of animal away from something is just spray the device with chemicals like roach / wasp spray, bug spray, poison, tree poison, etc, animals do not like chemicals.

my mom had those birds building mud nest under the porch, we tried all kind of stuff to keep them out. 2 months ago i washed the nest away with a water hose and then sprayed the nesting area with wasp spray and WD40, what ever you have. they took off and have not come back, they dont like chemicals of any type

I know what ur saying but everything is a chemical/has chemistry . Food, water , & what they/we breathe …. All chemicals. Foreign chemicals not common to the local environment ….. yes that would probably dissuade local wildlife .
