A Landmark Bluebird Achievement
First Time In Four Years
As I have mentioned before in my Dark Legacy post, for the last four years or so I have had a bluebird pair with some type of genetic defect. This theory was backed up when Julie Zickefoose suggested I crack open an unhatched egg and confirm there was no viable chick in it. They would build a nest in my box, lay eggs and then the heartbreak began. Without predation, some of each clutch of eggs would just not hatch. Then, of the two or three that did, only one and rarely two would actually fledge.
