The young start to leave the nest box on average alter 19 days, and then the forest becomes a very lively place. The young birds fly rather badly and flutter about from tree to tree enthusiastically making a "sirp-sirp-sirp' like call. The parents producc a similar sort of call and this serves to keep the young in contact with the parents. For the first few days the young are relatively immobile and cannot follow their parents. Their anxious cries reveal their whereabouts not only to the parents, but also to enterprising predators such as crows, which often take young during this short but vulnerable time. Once the young have left the nest they do not return.
