Near Lake Eufaula in the spring of 1984, gray squirrels enlarged the entrance holes of 2 Eastern Bluebird (Siala sialis) nest boxes to approximately 70 mm in diameter. In an attempt to stop any further destruction I began to reduce the local squirrel population, leaving the carcasses in the nearby woods for the scavengers. Before the front of the damaged boxes could be replaced, a pair of Tufted Titmice (Parus bicolor) nested in one of the boxes and fledged 4 young. I decided to wait and repair the boxes in the fall.
