LLYN BRENIG - MARCH/APRIL 2023

Link to August 2022

With last year’s male LJ2 arriving on the 6th of April and partner LM6 the 10th of April, I thought I would start a thread now for the new season in case they return earlier after a successful breeding season last year. The nest and surrounding area has recently been prepared by Welsh Water for our pair’s arrival.

Background to the nest:-

Many thanks to AG  who wrote this preface to the Llyn Brenig thread for us below.  (I’ve just edited extra information)

Llyn Brenig is a reservoir on the border between Denbighshire and County Conwy in North Wales. It is managed by Welsh Water;  the osprey project is a partnership between them and North Wales Wildlife Trust.

One pair of ospreys (Blue HR7 (M) 2014  Lake Menteith, Scotland and Blue 24 (F) 2010 nr Rutland)  raised a single chick here each year from 2018-2020,  Z9 (F) Luned, KA5 (M) Roli and KC5 (F) respectively. Sadly, KC5 died after fledging, colliding with a wind turbine.

Neither of this breeding pair returned in 2021, when the nest was taken over by 2 Scottish birds, LJ2 (male) and LM6 (female), both 2018 chicks. The nest was vandalised the night after LM6 had laid her first egg; while the two could not continue to breed they did stay close to the site until normal migration time.

A new nest was erected in 2022 with additional security and a streaming camera in place. A new hide was also built.

LJ2 and LM6 returned and successfully fledged 2 chicks, X6 Olwen (F) and KA9 Gelert (M) 

LM6 lost her blue darvic ring on the nest. It was recently recovered by Welsh Water and kept for display in the exhibition later this year.

  • Thanks Janni - the unringed female is still there.

    Close up of her as curious to see if by any chance there was a metal ring as we know LM6 has lost her blue darvic.   

    But no - no rings - we still await LM6

  • Thanks Janni, you’re now officially our chief spotter at this nest!! SmileRaised hands

    Thanks Karen for doing what I was going to do re checking for BTO ring!

    Interesting then, a new bird at this nest. We watch and wait. Blush
  • Oh Glider, that is a responsibility! I know you are a super supporter of this nest and I always check to see if you have made a comment before I submit one! So I think of myself as laying down a marker so you can check back to see what's been happening!

    I will continue to check on the nest and post anything that appears new or different. Then I can see what information you add to the story.

    Now that’s what I call teamwork! BlushThumbsup 
    It really was a lovely nest to watch last year although I only started watching closely after the first egg had hatched as there was concern that LM6 wasn’t feeding the chick.

    I’m super excited to see LM6’s arrival this year and everything else from thereon. The chicks last year were absolutely amazing. Two hearts

  • The unringed female stayed on the nest most of the time until around 18.15. I didn’t see LJ2 return to the nest whilst she was there. (Just short of 2 hours) She did make a couple of contact chips when she first landed. She also moved a stick or 2.

    Not too dissimilar to LM6 (bottom)

    Samples from the first and longest visit:

  • Thanks for the videos Scylla, it’s great to hear the Osprey chipping, see the wind stroke her feathers, the water rippling along with the glistening reflections of the sun dancing on the surface.

    What a difference being able to have videos on this site at last, much appreciated. Heart eyes
  • LJ2 lands on the nest 09.38 and announces his arrival.

  • Wonder if he was off visiting yesterday afternoon? Glaslyn folks were half expecting to see him!

  • 09.46 surveying his territory. Where are you LM6, I’m waiting!


    He moves to the perch. I can hear geese. Probably including the greylag that had her sights on this nest!
