Dennis and I did a run around on Saturday and we didn't see Hart or Joli at all anywhere in the Logan territory where they know they like to hang out. This isn't a concern, it isn't unusual for pairs to disappear for hours or even a day or two during the pre-nesting period. Jules and Beau used to do it all the time, kept thinking they were going to find some equally terrible to nest on but then they would return and go back to their original horrible spot. Hart was like a ghost last year, almost never found him around the nestsite, didn't mean he wasn't paying attention, just that he like to hang out further away than Cowboy did. Beau was like this when Jules was nesting - hard to find him anywhere near the nest or her until we moved their chicks at banding, then we had no problems finding either of them.
