Another Rutland visitor to the Dyfi Osprey Project

If you have been following the website recently you’ll know that one of our two-year-old Ospreys, 12(10), recently visited the Montgomeryshire Wildlife Trust’s reserve at Cors Dyfi. She hasn’t been seen there since, but earlier today another Rutland Osprey made a brief visit. This time it was 00(09), the three-year-old female who arrived in Rutland in late March. With the Dyfi breeding male, Monty, away fishing 00 made quite a nuisance of herself before her half-sister, 03(08) – or Nora as she is now better known, finally left the nest to chase her off. Before she did Emyr  and the Dyfi Osprey Project team managed to get this photo of 00 to confirm her identity.

00(09) intruding at Cors Dyfi

Since her return in March, we’ve seen 00 at least once every week – often intruding at our established nest sites. We’ve often wondered how far afield she’s exploring during her absences from Rutland and today’s sighting at Dyfi sheds new light on this.

So what is 00 doing? Well, put simply, she’s looking for a mate. Despite the fact that three different three-year-old males have recently returned to Rutland, none of them have settled at a nest yet. 00’s repeated intrusions at our established nest sites shows that she is keen to find a vacant territory – and a male to share it with. As the video below shows, she even spent a day on the Manton Bay nest before the return of 5R’s regular mate. As we’ve said before, Roy Dennis’s satellite tracking of Rothiemurchus – a three-year-old male Osprey from Scotland – demonstrates how much young Ospreys often range, and 00 is no different. If she was to find a lone male at a nest in Wales then there is every chance that that’s where she will stay – it’s what happened to Nora after all. This again shows how crucial our work at Rutland Water will be in the birds’ re-colonisation of southern Britain.

This latest sighting really does demonstate the value of ringing. It goes to show that whilst satellite tracking has added immensely to our knowledge of Ospreys, ringing is still incredibly important too. It also shows that although Dyfi and Rutland are 130 miles apart, this is no distance for an Osprey. We last saw 00 in Rutland on Tuesday this week. I wonder how long it will be before we see her again? We’ll be sure to let you know.
