Tweedledum and Tweedledee – Tagged and ringed

Tweed Valley’s favourite chicks are ringed and tagged

Eve and tagged main nest chicks

The main nest chicks were 6 weeks old last week and so it was time for them to be fitted with their leg rings and the GPS trackers. Of all the ospreys in the Tweed Valley Osprey Project area it is the main nest chicks that tug at the heart strings the most, due to the connection via the live camera link. These youngsters have been watched and their fortunes followed since they first broke out of their eggs, and their life stories link back even further. We have followed the relationship between the two parent birds, Mrs O and SS, since they first got together last year.

A Proud Dad

They have proved to be fine parents/ SS, the proud dad, is now 19 years old and these two youngsters bring his total number of chicks raised to adulthood to date to 29. This is his first brood of chicks with first-time mum Mrs O. In 2015, one of his chicks FX9 was fitted with a tracker, but the bird vanished after only a week from fledging and the device never transmitted any further signal.

This year’s two special chicks will be the first of his extensive osprey offspring that we will be able to track. Forest Holidays have very kindly sponsored the tracking of these two chicks, and have paid for the data subscription for the next three years. This will mean that we can follow their migration journeys and their lives up to the point where they settle and begin to breed as adult birds. Two representatives from Forest Holidays (Pauline Lynch and Margaret Turner) were invited to watch the juveniles being fitted with their rings and trackers.

Eve Schulte climbed the nest tree and lowered the chicks to the ground to Tony Lightley, who fitted the blue coloured Darvic rings with digits LL6 for the female chick and LL7 for the male. Then Dave Anderson fitted the GPS trackers. This team from Forest Enterprise carried out the procedures under special licence from SNH and BTO as part of the ongoing monitoring of the ospreys for Tweed Valley Osprey Project.

Naming the birds

Forest Holidays invited members of the public to name the two chicks via an online vote, and the names selected are Tweedledum (LL7) for the male and Tweedledee (LL6) for the female. The names reflect their origins within the Tweed Valley, while also bringing to mind the curious little characters from Lewis Carroll’s book ‘Alice Through the Looking Glass.’ In fact, Carroll did not come up with the names – they were first penned in a poem by John Byrom, highlighting the petty squabbles between musicians. We have witnessed some squabbles in the nest between the two siblings, and now as soon-to-be adults, we hope that this pair will make a smooth transition into adulthood. We await their first tentative flights soon.

Handsome young male also tagged

A further young osprey from Tweed Valley Osprey Project area has also been fitted with a tracking device. This single chick in the nest identified by leg ring LK8 has been reared by parents who had three eggs in total, but two didn’t hatch. The un-hatched eggs are most likely attributable to the very hot summer leading to dehydration. This is the first osprey from this nest site to be fitted with a tracker, and it will be interesting to follow his progress and compare his life story to the main nest chicks from the same year as him.

Releasing Tawny owls into the wild

Eve releases a young tawny owl

Across the district, some young orphaned tawny owls have been released recently into vacant owl territories. The owls were rehabilitated by the SSPCA, Fishcross Centre, and Forest Enterprise staff Tony Lightley and Eve Schulte. They monitor the owls in the Forests, and were able to select sites for their safe release into the wild where previously occupied owl nest boxes had become vacant.

It was amazing to see these young birds make their first flights to freedom and into the wild. We hope that they manage to grow strong and establish themselves into their new territories, and maybe take up residence to breed in the boxes next year.
