I want to get the songbirds back in our area but there's too many magpies, crows and herons.

One year we had 3 sparrows for a month or so and then they vanished.

We also get a single robin most years but couldn't tell if it's the same one.

I've planted trees and bushes with berries, I've got a bird house feeding station that the pigeons and magpies get into.

If I do anything that may scare the bigger birds it would also scare the smaller birds, such as a fake owl or falcon cries played on a speaker.

Going to put up 3 small bird boxes on the side of the house that doesn't get direct sunlight all day and see if that helps in a few years.

We have cats in the area too so I'm not surprised the birds stay away.

I wonder if playing birdsong would attract them or just put them in danger?
