Watch: Mid Wales osprey chicks fledge on same day

While the oldest Merin was first off the nest followed by sister Celyn, the youngest Brenig was quick to stake his claim to the skies by pushing both his sisters off their perches once he took to the air.

Despite a four-day age gap between Merin and Brenig, all three fledged within around three hours of each other – something which staff at the Montgomeryshire Wildlife Trust said is very unusual.

Emyr Evans, from the Dyfi Osprey Project, said: "After watching helicopter flight after helicopter flight for the past few days, all three chicks fledged within hours of each other.

"First to go was the oldest Merin at 8.22am. 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 11.39am Celyn was next to go followed by her brother shortly after at 11.40am. Both flew to the station mast at Dyfi Junction before finally flying back to the camera pole.

"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, the other two had caught up developmentally?"

Mr Evans said he had thought the excitement was over for the day, but Brenig had other ideas.

He said: "Brenig managed to land on his sister Merin, knocking her clean off the camera pole. He then knocked his other sister, Celyn, off. Neither he or Celyn could recover aerially and landed on the ground.

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

Fledging involved the juvenile bird leaving the confines of the nest in a controlled flight.

All three juveniles will stay around for another five to six weeks before setting off for Africa. They will then remain abroad for two years until they mature before returning to the UK to mate.
