Blue 24 is another Rutland female that has been returning to Wales since 2013.

 Blue 24 shows off her Blue Darvic ring which has somehow got damaged sometime in 2013

She spent the summers of 2013 - 2016 in and aroung the Dyfi valley and was persistent with her attempts to take over the nest and become the breeding female. She was unsuccessful.

 And another nest
 And another nest..

While she attracted the attention of a number of males including Monty, Blue 24 was not able to secure both an nest and the undivided attention of a male and so did not breed during her time on the Dyfi. 

Blue 24 has taken a liking to Monty - or is it his nest she's after?


Blue 24 was back early in 2016 (25th March) and valiantly defended the Dyfi nest from other female ospreys, including yet another Rutland bird, Blue 5F (2012)

Unfortunately however, as all four breeding females successfully returned to Wales that year Blue 24 was to be unlucky again.

Blue 24 is a beautiful bird with extremely white head plumage, making her fairly easy to identify from distance.

2016 was a challenging season for Blue 24. For the first time on the Dyfi we witnessed a polygomous situation develop where both Glesni and Blue 24 laid eggs fertilised by Monty. You can read the full details here.

In March 2017 the second nest platform was removed under licence from NRW. It was replaced at a more suitable distance from the main breeding nest. This action was taken in order to avoid another season with a polygamous breeding and the impact that could have on the main nest. Blue 24 did return to the Dyfi in 2017 but was absent for most of the summer.

After not seeing her for almost two month, on the 1st of September 2017, who should appear in the Dyfi nest? You guessed it, an end of season visit from Blue 24. Where had she spent the summer?

In 2018 Blue 24 successfully breed for the first time on a nest platform at Llyn Brenig in North Wales. She raised one chick. In 2019 she returned to the same nest and again raised a single chick. She does still pop in to the Dyfi nest from time to time!
