Be quite they said they would be right back !
Well the Bluebirds did not accept the boxes in the yard so they went to a neighbors. My neighbor was graceous enough to let me share in his Bluebirds. I cleaned out the mess the Sparrows made and as soon as I did another male Bluebird was checking the boxes out again. Meanwhile at my neighbors, they thought there was two little ones well evidence is pointing to three !!! lol You can see they will not be in the box much longer. EVIDENCE three little heads !!
