Idea for protecting baby birds and new canes from squirrels
I've ordered some birdhouses and I don't want the squirrels to get any baby birds that might hatch someday.
There are 14" square wire grids, powdercoated metal, that companies make in a kit to make storage cubes. A few years back the guinea pig community started using the grids to make guinea pig homes. The kit comes with little connectors or one can use zip ties.
What about enclosing birdhouses with a grid cube (the openings are 1 1/2", enough for birds to get in but not squirrels) and also enclosing a tender new cane?
