Footage retrieved from Nest 3 has revealed the final two Kielder juveniles have fledged.
Archer fledged on 28 July between 08.00 BST and noon. She was 59 days old. The likeliest time for her departure from the nest is around 10.30. At the equivalent of 10.31 there was a fix – which Paul considers accurate – about 50m from the nest. (Many fixes are not in the correct position when the ‘object’ is stationary.)
In both the 1 hour recordings later that day Archer was absent from the nest.
The 3rd juvenile is Nest 1A’s Ayle.
It wasn’t until Sunday’s footage that we saw Archer flying.
Since then, she has had a few flights. But the frequent rain has inhibited her – and the other fledglings – from gaining experience.
The final youngster to fledge was Acomb. The maiden flight could have been this one, on 30 July at 07.55.
As can be seen from the first 2 images, Ayle is still spending plenty of time at Nest 3. There are some extremely interesting recordings. Another post will cover the behaviour later today.
