Only thing that has really worked is when Red Tail Hawk comes around. All he leaves is feathers. Doesn't come around often enough.

A funny back story, but once my neighbor saw all them dead birds, he used a shovel and quickly scraped all the dead birds into the trash. The neighbor stood outside wondering where his homing pigeons went to, never knowing their real demise.

I use a fake owl the only downside is that you have to move it from time to time.

This is true of all visual or auditory deterrents (fake predators, flashers, predator calls) - if they don't change the birds get used to them and will return.

Possibly, but far more likely you are seeing a Cooper's Hawk.

No stripes on tail are those of Red Tail.
