After watching helicopter flight after helicopter flight for the past few days, all three chicks have fledged this morning within hours of each other!

First to go was the oldest, Merin. She is 54 days old.

Glesni hadn't realised that one of her chicks had fledged, and by the time she looked up she thought the unfamiliar sight of a juvenile osprey flying above was an intruding osprey.

Then at 11:39 Celyn was next to go followed by her brother shortly after at 11:40. Both flew to the station mast at Dyfi Junction before finally flying back to the camera pole.

The aggression we saw from Glesni at the end of the video is directed towards Monty - we saw this last year too. It is probably a response to Monty not going fishing, compounded by what must be a stressful and highly changeable time for her.

We all thought the commotion was over for the day until this happened...

Brenig (right) managed to land on his sister Merin, knocking her clean off the camera pole. He then did a fly-pass and knocked his other sister, Celyn, off. Both he and Celyn could not recover aerially and landed on the ground.

Grounded - was Brenig stranded?

Thankfully, both birds managed to take off again and were soon back on the nest, including big sister Merin. Monty returned shortly afterwards with a mullet, to everyone's relief!

Here are the respective ages of all three 2015 fledglings as compared to the fledging ages of previous Dyfi chicks.

Many thanks to everyone that entered the Great Fledge Competition and congratulations to Pamela (first prize) and Tilly and Joy!

Despite a four-day age gap between the oldest (Merin) and youngest (Brenig) chick, all three have fledged within around three hours of each other on the same day. This is highly unusual and the first time we have seen this happen in Wales. Maybe the heavy winds and rain of the last few days prevented Merin from fledging and by the time the weather had improved today, the other two had caught up developmentally?

All three juveniles will stay around for another five to six weeks, using the nest as a base. It's been a memorable and exciting day, let's hope tomorrow restores a bit more calm to the nest!

First flight successful, Celyn lands on the larch perch for the very first time
