I know this isn’t strictly about birding but who doesn’t like Eastern Bluebirds?

So this spring I put up two bluebird nest boxes (X-Box design on EMT posts) only to have the bluebirds repeatedly evicted by house sparrows.

A few times I ready about using fishing line to deter the house sparrows, and it has actually worked! I attached two horizontal beams to the tops of the houses and then hung monofilament weighted with large hex nuts.

That was about six weeks ago and now we have a bluebird family in one and house wrens in the other.

Edit - on my lappy so I’ll post some links

    I wonder if this would work for my feeders, how clever! They’re such a menace.
