It’s been a very slow start to the Tweed Valley Osprey story this year because we’ve been waiting for the arrival of our main nest birds.
At just about the point when we believed that white leg SS was not going to return this year, he amazed us all, by returning with a stunning new partner. The new female is a blue ringed bird with the letters AS6. We now know – courtesy of the Kielder Osprey project and some keen osprey followers, Ann and Paula – that this bird originated in Ross-shire from a site at Muir of Ord in 2013. She made a stopover at Kielder on 17th April where she checked out the nest site there. We wonder where did white leg SS meet her? Did they pair up when she arrived at the Borders or had they already met beforehand? They both appeared together at the nest site for the first time on Wednesday 20th April and then were both firmly established by 21st April when the female was first identified by Tom who was on duty at the Wild Watch room at Glentress.
The pair managed to eliminate all of the competitors for the nest very quickly and have taken their place on the nest site. We can expect eggs soon and for the first time, we will have late chicks in the Tweed Valley Osprey Project, so this will be a long season. Any chicks will be hatched almost a month later than usual for this site and so it will be interesting to see if this has an impact on the survival rate of the young birds. Fingers crossed for some good weather and plentiful fish.
Contenders for the throne
Prior to the return of White leg SS and his new female partner blue AS6, ospreys had been visiting the nest and one bird was thought to be the female from last year. This was an unringed bird that sat on the perch next to the nest and seemed to be expecting that her partner may return. We are not sure if she is still around or whether she has moved on.
A blue ringed bird seemed to have taken up residence for a while and was coming in to feed there each afternoon and he was spotted early in the day too.
Paula, a follower of the Tweed Valley Ospreys made some keen observations on the live streaming camera and took some great photos for the project, of the birds seen at the nest from the internet. We have no clear image of the ring number of this bird but we think it could be CJ1.
Another visitor to the site while it was still vacant was a blue ringed bird and the lettering appeared to be CL7, this was one of the chicks that was ringed at the original back up nest in 2013 with the children from St. Ronan’s School as they took part in the 10th anniversary project to produce the Tweed Valley osprey book, Time Flies.
News of Tweed Valley ospreys further afield
One of the Tweed Valley Osprey Project birds has returned to Kielder where she has finally overthrown the partner of the male bird there and has settled in. She is White leg EB and came from a Tweed Valley nest in 2007 and was one of a brood of two. She has been popping in to Kielder for a few years now and had a fling with the male bird ‘37’ in 2014 before the resident female returned and sent her packing! This year though she seems to have won her prize and remains at nest number 2 with male 37. EB is now sitting on eggs.
FK8 satellite tagged
FK8 is the young Tweed Valley female bird that flew to Portugal on migration when she left Peebles and she is still there. She has settled into an area in the west of Portugal near Sines and she has a leisurely life, spending her time between two reservoirs but mostly at the Barragem da Morgavel.
The mother of FK8 was found dead at the end of last season, she was a green ringed bird DN and her partner was yellow 8C. However, the good news is that there are reports that birds have settled on their nest site this season. More ospreys moving into the area mean that vacant nests do not remain vacant for long usually. We have checked our remote camera and can now reveal that the new female at this site appears to be a white ringed bird but we cannot read the letters yet. She is sitting on three eggs.
We are delighted to have received reports that another Tweed Valley bird, blue ringed CK4 has also been spotted in Portugal. On February 11th Georg Schreier photographed CK4 with another unringed osprey, flying over the salt pans and channels just west of Faro airport in the Park National da Ria Farmosa. He reported that there have been about 10 ospreys overwintering in that area within a 30km stretch and along the coast.
A Spanish Visitor
We have just received news that another Scottish bird from the Tweed Valley back up nest no.2 has been overwintering in northwest Spain. Antonio Sandoval Rey sent in a video link to see a blue ringed osprey ( PV0) being mobbed by crows at the Abegondo-Cecebre Reservoir near A Caruna City.
This bird is from a brood of two in 2015, a third egg was found in the nest at ringing time with a fully formed chick inside it but it had a double shell and the chick had been unable to break out.
