Rutland Osprey fledglings – Where are they now?

As chicks, our ospreys are fitted with darvic leg rings – these unique rings allow our Ospreys to be easily identifiable should they be spotted elsewhere in the world. So, where are our Osprey fledglings now? Many of them return to breed at Rutland, after 2 -3 years in West Africa, but some of them move on to new breeding grounds elsewhere in the UK.

Glaslyn Ospreys 

The Glaslyn site is located to the west of Snowdonia National Park in Wales. Ospreys first successfully bred at Glaslyn in 2005. Since then, 30 chicks have fledged – below are the Rutland fledged ospreys that have been linked with the site.


5F(12) hatched at an off-site nest in 2012. Her mother is the satellite tagged female 30(05), hatched at the Rutland Site B nest in 2005, and her father was the translocated Rutland male 08(01).

After fledging, 5F migrated to Tanji Marsh in Gambia for the winter. She was first spotted back in the UK in April 2015 at the Glaslyn nest – she did not breed in 2015 but remained in the Glaslyn area for the remainder of the summer. In spring 2016, after returning once again from Gambia, 5F was spotted mating with Aran (a bird already breeding at Glaslyn with another female!). She did appear to be incubating eggs for a while in the Glaslyn area, but the nest failed to produce any young. She returned to Glaslyn again in 2017.


11(98) was one of 64 Ospreys that were translocated to Rutland Water between 1996 and 2001 as part of a pioneering translocation project

11(98) was one of the chicks translocated to Rutland in 1998 as a chick from Aviemore in Scotland. Unfortunately, after fledging, 11(98) never returned to Rutland – he did however nest at Glaslyn, and between 2005 and 2014 he fathered an amazing 30 chicks, 26 of which fledged. He was last seen in September 2014, when he was 16 years old.

Dyfi Ospreys

The Dyfi visitor centre is located to the south of Snowdonia National Park in Wales. Ospreys first started breeding at Dyfi in 2011. Since then 13 chicks have fledged from the nest. 3 female ospreys fledged at Rutland have made their way to Dyfi, and 2 of them have bred successfully.


12(10) aka ‘Glesni’


12(10) ‘Glesni’

12(10), also known as ‘Glesni’, fledged from Rutland Water in 2010, was breeding female at Dyfi. Her parents are the well known Rutland pair 08(97) and 5N(04). Glesni breed with  ‘Monty’ at Dyfi from 2013. However breeding is not always easy for Glesni. In 2018 Glesni did not return and her mate is now breeding with another Rutland osprey! 




24(10) on the Manton Bay nest 10th May 2013

24(10) fledged from Site O at Rutland in 2010 – her parents are male AW(06) and an unringed Scottish female. 24(10) is yet to successfully breed, although that is not through lack of trying! 24(10) can regularly be spotted around Dyfi, and in the past has unsuccessfully tried to take over the nest Glesni shared with Monty. 24(10) has also been spotted at Rutland Water since fledgling. 


03(08) aka Nora

03(08) 'Nora'

03(08) ‘Nora’

03(08), also known as Nora, fledged from Site B at Rutland in 2008. Her parents are 03(97) (a translocated Scottish bird) and 05(00). Nora first bred at at Dyfi in 2011, with Monty. Remarkably, for first time parents, Nora and Monty raised 3 chicks, all of which fledged successfully and made it to Africa for the winter. In 2012, Nora and Monty returned to Dyfi to breed again. Unfortunately conditions were harsh, and in June of that year one of the worst storms Wales had seen in over 100 years struck. Against all odds, Nora and Monty managed to raise one chick. Nora has not been seen since departing from Dyfi in August 2012.

Male Osprey 07(97), one of the translocated Scottish birds to fledge from Rutland

Male Osprey 07(97), one of the translocated Scottish birds to fledge from Rutland










Male 07(97) was one of the birds translocated from Scotland to Rutland in 1997. He fathered the first Welsh-born osprey chick in 2004, near Welshpool in mid-Wales. Unfortunately, whilst 07(97) was seen at the nest site the following year, his mate Red6J (a Perthshire born osprey) did not return.



01(99) was another translocated Scottish bird that fledged from Rutland. She never returned to Rutland, but was seen at Welbeck Lake in Nottinghamshire in June 2001. The year after she was seen on an artificial nest in Dundee, and she bred successfully there between 2002 and 2004, raising eight chicks. Unfortunately she did not return in 2005.


As well as Glaslyn and Dyfi, and of course Rutland, breeding ospreys are present at many other locations around the UK. There are established osprey nests at Kielder in Northumberland,  Bassenthwaite in the Lake District, and Loch Garten, Loch of the Lowes, and Aberfoyle in Scotland, to name a few!
