Gweilch y pysgod yn Llyn Brenig

The osprey, a majestic and magnificent bird driven to extinction in Wales but now is making a comeback due to the efforts of conservation projects like the Brenig Osprey Project, writes Sarah Callon, North Wales Wildlife Trust’s BOP Project Officer.

The Brenig Osprey Project was started in 2013, a partnership project between North Wales Wildlife Trust and Dwr Cymru Welsh Water, at the water company’s visitor attraction Llyn Brenig.  Five nests were erected as ospreys had been previously spotted in the area.  In 2015 one of the nests was chosen by CU2 “Jimmy”.    

In 2017 a pair, female Blue 24 and male HR7, visited the Brenig nest.  (Blue 24 hatched at Rutland Water in 2010, granddaughter to White 03(97) a male osprey who was translocated to Rutland Water in 1997).  To everyone’s delight in 2018 the first chick at Llyn Brenig was hatched; Blue Z9 Luned.  Blue 24 and HR7 hatched one chick, KA5 Roli, in 2019 and another, Blue KC5 Dwynwen, in 2020.  Sadly Blue 24 and HR7 did not return from migration in the spring of 2021.

2021 saw two new ospreys take over the Brenig nest; female Blue LM6 hatched Menteith, Stirling in 2018 and male Blue LJ2 hatched in South Argyll in 2018.  Everything was going to plan for this new breeding pair and on the 30^th April 2021 LM6 laid her first egg.

That evening, however, in devastating and dramatic circumstances, the nest pole was illegally felled with a chainsaw.  A terrible wildlife crime had been committed and the newly laid egg was lost.

A temporary replacement nest was put up in the hope that the pair would lay more eggs but they did not.   A tremendous public reaction of support and donations meant that 24-hour security could be put in place to prevent this happening again.  LM6 and LJ2 did however stay around the area and set off for migration.  During that winter BT Openreach donated and installed a new nest pole, LM6 and LJ2 returned to the new Llyn Brenig nest in the spring of 2022, much to the project’s relief.

The 2022 season was a most successful season, especially after the devastation of the previous year.  Two chicks were successfully raised by LM6 and LJ2 to migration; Blue X6 Olwen and Blue KA9 Gelert.  We hope to see them return to the area in 2024 as two-year olds. 

2023 was also successful season as again two chicks were raised to migration; Blue 7B5 Dilys, hatched 27^th May and last seen at Llyn Brenig 30^th August.  Also, Blue 7B6 Mari, hatched 29^th May and last seen at Llyn Brenig 26^th August.

We are excited to see what 2024 will bring!
