The second species is the Bluebird. We walk Peanut up at Lorimer park which butts up against Fox Chase farm. The farm is owned by Philadelphia Parks Commission and has acres of pastures and cows that are tended by the 4-H club. Someone, a long time ago, installed Bluebird boxes on the fence posts. I remember seeing Bluebirds in the park years ago but haven't seen any lately and wondered why.
At a recent DVOC meeting, the speaker told us that Bluebirds need clean boxes to build their nest. It dawned on me that the Fox Chase Farm boxes were probably filled with old nest material so I went around and cleaned out 9 boxes and purchased 5 new ones to install where I saw long stretches without an old box.
My work paid off! Today, Connie and I saw Bluebirds at 3 of the boxes including one of the new boxes.
