I was delighted to look underneath the cardboard pieces in the stacked toybox planters and see two little eggs sitting in the nest. The birds make such frequent use of this excellently concealed and protected nesting spot that i get the nature channel all spring even though i have no tv service.
She laid an additional egg every so often until there were 6 sitting in the nest. Some birds sit on unfertilized eggs until it becomes apparent that they will not hatch. Then they break the eggs or roll them from the nest and vacate. So the question is, “Are these eggs fertilized?” One can hope. 🙂
