The videos for June 30 gave me a heart attack.
First "De Val" (the fall) shows all three chick out on the limb at about 4:30 am. One of the chick decides to try to leap from the branch to the top of the nestbox. There is a lot of wing action and talons scraping on the sloped roof, but the chick slides off and falls. They show this part in slow motion as well, so you can clearly see the chick fall from view.
Then "Avonturier" (adventurer) shows two chick at between 7 and 8 am outside the nestbox and in the background you can see the third chick making it's way back up the branches till it is back with it's siblings. YAY! Way to go chick!
