The first egg has been laid in the Friends of the Ospreys Pont Croesor nest. Egg laying behaviour was observed late yesterday evening and today Blue 014 and Z2/Aeron have been taking it in turns to incubate on the nest.
Congratulations to everyone concerned with the nest.

After the delayed start to egg laying we had been wondering if we would get a full clutch this year. We got the answer at 13.29 with the arrival of egg number three. This one should be easy to keep track of as it is much whiter than the first two.

Now incubation has started proper, Telyn’s (and Idris’) goal will be to keep their eggs as close to 36C (97F) as possible for the next month.
36C is the optimum temperature for osprey chick development.
Telyn achieves as she is warm-blooded, despite a cold frost this morning.

Remember these two from 2021?
Dysynni and Ystwyth. They're due back this month onwards.
Keep Calm and Look Up...

As we enter the month of May, when do eggspect the first chick to hatch?
Telyn is around mid-way through incubating now, so another three weeks or so - 21st May onwards.
Telyn hatched at her Rutland nest on 22nd May 2013 - so she will be a decade old this month. She could well have a chick hatch on her 10th birthday

Ospreys are continuously changing their inner-nest environment to best suit their needs throughout the season.
So right now we have soft moss and grasses as bedding for the eggs, whilst the outer walls of the nest have been built inwards, to protect the incubating parent from the weather.
The nest will look a lot different as soon as the chicks hatch and by the end of the season, Telyn and Idris will have enlarged and flattened it out so it serves as a landing pad. Nature's own aircraft carrier.
Very clever stuff.

Lovely tawny owl fledgling showing well from the Obs today - probably just hours out of the nest...

Science Sunday
We have seven high-resolution 4K cameras on and around the Dyfi nest.
These provide us with a detailed picture of the behaviours and ecology of our ospreys each year. They are also amazing at capturing visiting ospreys - even the ‘danglers’ that are only happy to show a foot or a leg before being ushered away by Telyn or Idris. That's often enough for a positive ID.
We get more and more intruding ospreys every year - this is a far cry from say 15 years ago when another ringed osprey in the area was a champagne-opening event.
As the Welsh population grows, the breeding territories act as an attractant to new, young birds looking to settle and breed in the vicinity of successful nests.
Male ospreys are ‘philopatric’, meaning they tend to return to the colony/vicinity of their birth to breed themselves - Tegid, Dinas and Aeron all good examples of Dyfi males that have returned to breed in Wales, all within around an hour’s flight from the Dyfi nest.
Over 99% of the world’s osprey population built their own nests, but we have several man-made platforms in Wales; a highly successful conservation tool to attract new birds, facilitating breeding dispersal and population expansion.
Here are the four ringed ospreys we have sighted already this season (there are many more that have been unrigned):
INTRUDER (RINGED) LIST 2023:
1. Blue Z5 – 18th April. A 2020 female - Tegid's daughter from private north Wales nest (Friends of the Ospreys).
2. Blue 379 – 1st May. Female from Poole Harbour (2021), so our first two-year old of the season.
3. Blue KA5 "ROLI" – 1st May. Blue 24’s son from Brenig (2019).
4. Blue KC1, 3rd May. A 2019 male from private north Wales nest (Friends of the Ospreys).
Hopefully 2021’s Dysynni and Ystwyth are on their way….

We had a change to our regular programming last night on the LIve Streaming - we were treated to a few minutes of the beavers that live on the reserve.
We hope to do this now and again throughout the season.
