It's taken some years to get the birds to use this house. You can see where the squirrels gnawed and tried to increase the opening but never moved in. I have wanted and finally got CA Bluebirds to nest. These two chicks came after three before and one didn't make it. I'm hoping they will return next year. We'll see. Birdhouse by Marlene. Thanks for watching and leave a like @GT-dr6tp
