The new osprey pair are proving to be a real hit with visitors to the centres, and footage from the new ‘back up’ nest site shows the two handsome chicks are growing up fast. The ringed adult birds are absolutely, stunningly beautiful. The male bird is a powerful and proficient hunter and he is bringing in good sized fish which he passes straight over to the female which she uses to feed the hungry young ospreys straight away.
Home grown borders boy
We now have confirmation about the leg ring on the male bird and have discovered that yellow 8C is a bird which fledged from our number 1 ‘back up nest’ in 2004, in the Tweed Valley Project Area.
This is great news to know that birds born in the Scottish Borders are returning to breed in the area, and another proven success for the Tweed Valley Osprey Project.
We are still waiting to hear where the green ringed partner of yellow 8C has come from. We believe that the green rings date from the year 2005, but records so far reveal that she is not a Borderer! Maybe she is a Highlander, an English or Welsh bird. It will be interesting to find out and also it’s a good thing to strengthen the gene pool, to have local birds breeding with birds from outside the area too.
We ’ve had delightful news that one of the osprey chicks ringed at the ‘Back up 1’, nest site last year has been photographed on a sunny beach on the River Tinto, Huelva in Spain this summer.
The juvenile osprey has been fitted with a blue Darvic ring bearing the digits CL9 in white lettering. He is now a fully grown and magnificent looking adult, and – as can be seen from the photograph – is looking very fit and healthy while enjoying a summer break as a one year old bird. Next summer he may well look for territory for breeding and so it will be interesting to find out if he returns to Spain or heads back to the Borders.
Another Borders bred osprey has been spotted this summer over in County Wicklow in Ireland. This bird, bearing the blue Darvic ring CL1, was ringed in 2012 and his safe migration to Ireland really is very good news.
A few weeks ago I reported that a failed egg on the ‘back up 2’ nest site had been analysed and revealed a second shell layer over the top of the egg which it would seem prevented the osprey chick from breaking out. We had never encountered anything like this before but one of the volunteers within the osprey project, John Savory, has a science background and revealed that research into egg abnormalities shows that eggs can sometimes have double layers due to prolonged delay in laying of the egg. This, as far as we know has not been encountered in wild birds before.
The heron nest has become something of a sunny afternoon hammock for a sleepy heron taking afternoon siestas. It looks like it’s one of the adult birds as it has the distinct long, black head plumes and feathery chest finery which the young bird hasn’t grown yet.
