I will not let you reproduce
In the United States, the House Sparrow is one of three birds not protected by law (the others are the European Starling and Rock Pigeon, also introduced species). House Sparrows sometimes kill adult Bluebirds and other native cavity nesters and their young and smash their eggs. The House Sparrow is partly responsible for the near extinction of Bluebirds in the United States.

I keep a homemade “carcass” in my freezer and would love to add rotten sparrow eggs over the layers of scrap meat and fat to the container in the freezer. I’m hoping my carcass attracts a fox or coyote someday, but it’s more likely I’ll be feeding a pregnant racoon. Maybe she’ll leave my suet alone.
The House Sparrows have claimed this bluebird box as their own. It’s one of the only nests you can legally disturb. Here I am disturbing the nest with a stick, my favorite disturbing tool since childhood. The bluebirds sleep in the boxes, but only build nests in the spring and summer when they’re making babies.
The bark peeled away a few weeks ago and revealed this crack full of corn.
