I’ve been meaning to add a perch atop the bluebird house. Great idea.Rg
Watch those wrens my friend. They’re nasty little birds and will kill the bluebird chicks if they don’t destroy the eggs first. When we had wren houses up ( all gone now) one pair killed 5 of the other pair’s chicks. Pretty sure they were responsible for the demise of one clutch of bluebird eggs as well. Found them on the ground and in the nest box with little holes pecked in them.Rg
