First there was one, probably Dad. Then, yesterday, there were three, Dad, Mom and junior shown above. Dad had been sitting guard in the same hole for about a month, then a few days ago he was seen perched on a branch, then yesterday the whole family was seen perched up high in the same tree; that is, unless there is an other young one not yet spotted???

In the above image the one young owl is looking down from high up in the tree. The shot is not great as the light was bad.
