I have to admit--back in November, we were very worried that the birds may have moved on to another nest. It is normal that a nest is abandoned after six or seven years. We had heard from local folks that there were potentially two other nests within a few minutes flying time of our tree, and the fact that the birds were not hanging around very much had us concerned.
Based on the past few weeks though, things seem pretty much going the same as in the past. Let's keep our fingers crossed that it is a smooth start to the nesting season.
