Llyn Clywedog March - May 2023

Llyn Clywedog is a reservoir situated near the B4518 road north of Llanidloes, Powys, Mid Wales. The reservoir is owned and operated by Severn Trent Water, with oversight and regulation by Natural Resources Wales. A sailing club and a very active trout fishery operate on the reservoir. The fishery stock the lake with tens of thousands of trout every year. 

In 2005 Natural Resources Wales erected an osprey platform; this was eventually occupied in 2014, and has been used every season since then.

In 2022 the unringed osprey known as Dylan returned to the nest for his seventh season as the resident male. Since 2020 the resident female has been Blue 5F(12) (known as Seren - Welsh for Star). She hatched in Rutland in 2012. Previously she had for several years been unsuccessful in attracting the sole attention of a male to a nest at Pont Croesor. The previous unringed female (Delyth) did not return in 2020, and Seren 5F replaced her.  In 2020 Dylan and 5F Seren fledged 3 male young, in 2021 (a cold and wet season) only one male fledged, and in 2022 one female and 2 males. 5F Seren has regularly been seen in Africa in winter for many years - she was last reported as seen in the Gambia on 1 February 2023.

In 2022 5F Seren returned to the nest on 26 March; Dylan arrived on 5 April, which is later than he arrived in previous years.

There is no visitor centre or facilities. The nest can be observed from a temporary hide in a layby off the minor road. There is a footpath close to the nest which is closed and blocked off during the nesting season.

The nest is looked after by the area NRW ranger John Williams; he has a blog on this link. There is a more comprehensive history of the site in his blog. John goes well beyond the call of duty to support the ospreys and ensure that the cameras are running etc.

There is an active Facebook group for the nest on this link. The group tries to record all fish deliveries which are collated for analysis. 

There are 2 streaming cameras provided by Carnyx Wild. The  links for the live stream change every 12 hours, the latest can be seen on the playlist links below.

Camera 1 is a close-up of the nest. - playlist on this link

Camera 2 gives a wider view with two perches - playlist on this link This camera is not being transmitted at the moment due to condensation obscuring the view.

    Here's hoping y'all can see the fish that Seren is about to take off with - I hazsrd a guess that it was headless, more than that I dare not venture:

    Seren returned @ 07:08.

    I nabbed the 08:00 switchover so can sign off with a happy heart Heart eyes

    Haha I don’t know if I’d call it much progress yet Scylla, but I’m trying! Joy

  • 496 is home! He was the only chick who fledged in 2021; the other 2 eggs did not hatch. He landed on the nest at 18.44 this evening. From 2018 to 2021 10 chicks have fledged; 7 of them have now been seen as 2 or 3 year olds.

    Thank you for that thrilling news, AG Heart eyes

    Scuse my timeline being a bit out - I did try to stick with the embedded one but just couldn't read it.

  • Oh it is indeed thrilling news, thanks so much AG  - he knows his  (old home) and I am convinced at only just 2 years , he'll recognize his mater and pater  and no one  will convince me other wise so no reference to any  'expert'  knowledge please.      What a gem piece of news . How long have Dylan and Seren been together please anyone ?

    I only know that Seren took over from Delyth but not dates - but John Williams has done a nice history of the nest, I haven't read it yet because I'm rushing to give you the link while you're still around Slight smile

  • Delyth failed to return from migration for the 2020 season, which was the first year there was live streaming. 5F had visited Clywedog several times in previous years and been "seen off" by Delyth as the resident. When Delyth didn't return, she quickly took over as the beneficiary of Dylan's fishing abilities, and knowledge of the Clywedog.
  • Thank you Scylla, and yes, I've had a fab sunshine filled walk in the countryside
  • Thank you for the history AG  - really appreciate it . And  although I mourned Delyth was so pleased  for 5 F after her bumpy start in life

    That is fantastic news, thank you AG. What a record of return. It flips the records the other way around - wish all areas were as high as this.

    I remember watching 496 in 2021, he was such a well looked after chick. I felt sorry for him having no siblings but that was to his advantage I guess.
