As you can see, little brother is back home in the nestbox. We were hoping the rain would keep her glued to the nestbox even when we got close and the parents started freaking out. No rain but she didn't do anything foolish and we were very quick and minimalist in returning him to the nestbox. It was all over in about 12 seconds.
And yes, the other sister is fine. Dennis found her on his way to the Radisson as I was coming in with little brother. She's next door, many storeys above the street and it appears no worse for wear and in no immediate or particular danger.
Remember, no news is good news
The no news on other sister was definitely good news!!
