The cubs are ringed when they are 18-25 days old and on Saturday it was time for the three down balls S0, S1 and S2 to get their marking.
- You want to see the spread of them, how they establish themselves in the country, says ring marker, Lars Lexén.
Probably heading south
For just over a month, the cubs are so big that they move out of the box to the roof of the silo and begin flight training.
- Then they are around here and trying to make some changes.
Then in September they will probably head south if they do not think this is a good place, then they will stay.
In the clip, you can see when the peregrine falcons are ringed in their home, just over 60 meters above the ground.
