Question Last year we had a pair of eastern bluebirds raise two broods (8 young total) successfully. This spring (I think) the same pair returned to the nest box and diligently built a new nest. They then have mysteriously disappeared and we have not seen them for one week. Nest is still in tact and it does not appear that the box or nest has been tampered a with. There is a predator cone on the pole. We put out a second box about 100 ft away and not in line of sight. This box was in place when they built the nest in the other, but the new box shows no sign of any activity at all.
Any clue as too what may have happened or the likelihood of their return?

Answer Hi George. They may have backed off a bit due to the cold weather. On the dark side a predator may have gotten the female. I wait 20 days and then if there has been no activity I remove the nest. If you don't already have my free Bluebird book please send me your mailing address. Nearly 3100 copies are out across the U. S., Canada and Bermuda. Good luck. Bluebird Bob Walshaw. PS See page 19 for why you should have several boxes.
