A record number of osprey chicks have been observed at Foulshaw Moss Nature Reserve in Cumbria, marking a significant success for conservation efforts. Five chicks have been ringed and tagged this season, surpassing the previous record of three.
Cumbria Wildlife Trust attributed the increase to a new breeding pair joining the established long-standing pair. The new pair, identified by their leg rings as Blue 717 and Blue 476, returned to the reserve and successfully raised three chicks this year. Paul Waterhouse, the trust's reserve officer, expressed delight at the return of this pair, noting that their performance was typical for less experienced ospreys, having fledged only one chick in their first year.
The long-standing pair, known as Blue 35 and White YW, also continued their breeding success. These birds are estimated to be around 18 years old, nearing the upper end of their typical 25-year lifespan, making each year of successful breeding a valued outcome.
This species returned to Foulshaw Moss Nature Reserve in 2013, following a substantial habitat restoration program. Conservationists are monitoring the nesting sites, with one of the nests being particularly close to a public boardwalk, raising concerns about potential disturbance. Visitors are reminded to be mindful of the birds and to use designated viewing areas, such as the nearby hide, responsibly.
The tagging and ringing of the chicks allow conservationists to track their movements and gather data on their life history. The young ospreys are expected to migrate to the Iberian Peninsula or West Africa starting in September.
