The youngsters on Nests 1 and 2 are still spending most of their time dozing, preening and eating but in the bouts of exercise they are gradually becoming better coordinated. This video from 8 July shows several wing flapping sessions from all four juveniles.
Their feathers are still growing – in the image below they look well developed on VP.
But from this angle you can see the sheaths are covering a large part of some feathers.
VY is the most advanced at controlled flapping – unsurprisingly as she is a few days older than the other three. This was yesterday afternoon and she is now able to add the odd hop to the flapping!
The smaller size of Nest 2 results in the odd biff when one of the youngsters exercises near the sibling.
The chicks on Nest 2 are still being fed by Mrs 37 whereas on Nest 1 YA is delivering a fish then leaving the pair to feed themselves.
But usually Mrs YA lands and takes over for a time.
On 9 July around midday there were intrusions at Nests 1 and 3. It could have been the same osprey travelling between the two nests from the timing. Initially the male and then the female on Nest 3 tried to escort the intruder away but either it returned several times or there was more than one osprey.
