11:00 a.m. A pair of BLUEBIRDS showed up at Bob’s birdhouses today! They were doing battle with a single HOUSE WREN when Bob came over to the house to get me. I went out with him to watch what was happening. The WREN was gone, and both BLUEBIRDS were moving from house to house, trying to decide which of the three they might want. I hope one of the houses suits them.
