Oberhausen: male is back:

What a big annd wonderful surprise: the little male fledgeling suddenly appeared back on the platform. Begging for food no doubt, when the female was landing here around 8 in the evening. he was putting up quite a spectacel this little guy. And what a great flyer he is. He did come back all the way up to the nestbox. .
He stayed for a while and left, and came back. All three together for the night again.
