For this year’s opener, I’m starting with AG’s recent comments (end of August 2023-February 2024) which give an insight to what’s been going on at Llyn Brenig.

“There are some posts on the Brenig Osprey Project Facebook page with camera trap images and videos of voles, foxes and a family of otters. There is also an appeal for additional viewing equipment. The osprey watchpoint has a new verandah which will be a better base for scopes.There is a volunteer recruitment event at Llyn Brenig on 25 February if anyone in the region wants to join the merry band.All details at www.facebook.com/brenigospreyproject”

“Just a little more info on preparations at Llyn Brenig. The nest is on a pole in the water just into the reservoir from a peninsula, which was tree covered, As explained in the conservation plan plan prepared by Tim Mackrill, the trees have been felled over the last 2 years (they were mature and ready for use as timber). The brash from the felling has been gathered up and used to create a barrier across the peninsula in line with the hide which is there. Some tree stumps were left near the nest last year after the first stage of felling were used by the ospreys as perches for eating, and are still there. Last year the hide could not be used in moderate or high winds due to the risk of trees falling on it; that is no longer a concern. If you scroll up to Glider's post on 31 August above you can see the trees which have now been felled, and the hide in the middle of the line of trees.
Both cameras are still streaming - there is snow on the hills around the reservoir this morning.”
Background to the nest:-
Again, 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 in 2022 and successfully fledged 2 chicks, X6 Olwen (F) and KA9 Gelert (M)
LM6 lost her blue darvic ring on the nest. It was later recovered by Welsh Water and kept for display.2023 saw LJ2 and LM6 return to breed and successfully raise 2 female chicks 7B5 (Dilys) and 7B6 (Mari)
