Just a very quick update. We have just had news that Mrs O now has not one but 3 eggs! No new pictures so far, but we’ll post some as soon as we have them… It’s a brilliant start to the breeding season here in the Tweed Valley.
A time to celebrate
There is plenty to celebrate in Tweed Valley this week – we have fantastic news! Mrs O has laid two eggs, and also PX1 has flown into the UK and travelled to the far north, currently residing in Findhorn.
Paxman Osprey PX1 returns
The migration of PX1, (Jeremy Paxman’s osprey) suddenly resumed on 3 May. He had been taking time out from the journey in the Dordogne in France, and his data stopped updating after 26 April. It suddenly began to transmit again on 3 May, and we could see that he had left the area and headed into Normandy, where he spent a couple of nights. He teetered on the edge of the coast for a while, before making the crossing of the English Channel.
PX1 arrived in Dorset on 5 May at Tyneham, and flew over the Brandy Bay cliffs at 11.45am. He then proceeded northwards to the Bristol Channel and to Newport at 4pm, going on to cross Wales, flying on into Shropshire and finally Herefordshire, where he spent a night in the plantation forestry behind the village of Combe.
The next morning he left the area and flew westwards over Welsh countryside to Anglesey, where he changed course from Benllech, heading out into the Irish Sea. After an epic three hour sea crossing, he arrived at Barrow-in-Furness in Cumbria at 3.40pm. He spent time in the estuary and presumably caught fish to keep him going, then from Ulverston he made an overnight stop in Roudseawood Nature Reserve. On 7 May he left the area at 7am, headed to Keswick and then Carlisle.
Now in Scotland
PX1 was on course for his northward mission. Flying high, he entered his original homeland of Scotland in brilliant sunshine and high temperatures which must have been a pleasant homecoming. He flew over Hawick and Galashiels at a high altitude of over 900m, so there wasn’t much chance of anyone spotting him.
He headed for Aberlady Bay and crossed the Firth of Forth, dropping to 187m over the sea and down to 119m over East Wemyss. He never broke his journey, continuing on to Perth and then east of Pitlochry where he spent the night not far from Knockando. He was on the move at 5am on 8 May for a lochside fish breakfast, before flying up the Spey Valley and into Findhorn Bay by 8am. It is great to see that this bird has returned safe and well back to Scotland.
Mrs O – a mum to be
The other great news from Tweed Valley this week is that Mrs O has made her choice and settled down in the main nest with partner SS, and has now laid two eggs. The first one was laid on Thursday 3 May and the second on Monday 7 May.
She is a changed personality – motherhood-to-be obviously suits her because she is quiet! No more squawking from Mrs O – instead, she has been incubating the eggs. Mrs O and SS make a handsome pair, periodically looking down into the nest to observe their prize eggs.
Please note: Repairs to the Tweed Valley Osprey Project’s live web feed are currently being carried out – we will have more news for you next week. Thanks for your patience.
Hedging her bets
The intriguing antics of the ospreys at the main nest and the back- up nest no.2 continue this week. No pairs have settled down yet, as we would have expected by now. Mrs O is merrily stringing along two male ospreys, visiting both nest sites and being fed by both males. There have been multiple mating attempts by SS with Mrs O at the main nest site and most of the time she appears unreceptive. Since last weekend, she seems to have accepted the advances of SS, and if this has been a successful pairing, we could expect an egg to be laid any day now.
Mrs O is hedging her bets though, as she was over at the back up nest no.2 on Sunday when an eager male bird (FK0) flew down on to the nest. He was so keen to mate with her that he dropped his fish. She dipped down into the nest, making his attempt futile, so he flew off leaving the fish behind. Mrs O was not one to be ungrateful, immediately tucked in.
Hopeful homemaker FK0
Throughout the rest of the week Mrs O has spent more of her time at the main nest site with SS. The ‘back up’ nest has been frequently visited by FK0, who has been nest-tidying and removing moss from the centre, perhaps hopeful that his home-making will show his readiness to a potential partner for egg laying. If he is expecting Mrs O to be his settled partner, it’s likely he has been duped. Her infrequent visits to the nest with him amount to far less than the time she spends at the main nest with SS. She did not raise young with SS last year, and is keeping her options open for a fertile pairing. By flitting between nests and partners, she has the option of laying an egg in either nest, and pairing up in a summer partnership with either bird. It would take a Mystic Meg prediction to foresee which nest and male she will choose.
The third male, CL1, who was also seen with Mrs O on the back up nest has not been seen since, so perhaps he has moved on. Both CL1 and FK0 are Borders-bred ospreys, and it is good to see them both back on home turf and eager to breed in this area.
Tweed birds elsewhere
Further afield we have news of other Tweed Valley ospreys starting a successful breeding season for this year. FK4 has taken up residence with a female bird called Angel at Loch Doon and he has become known by the name Frankie.
White ringed EB (another Tweed Valley female) has returned to Kielder again this year and is back at her nest site with her partner. She has already settled down to incubate her eggs.
With settled pairings and news of eggs from Tweed Valley birds further afield, we are eagerly anticipating some domestic settlement with the nesting birds presently in Tweed Valley this year. While Mrs O is holding court and driving other females away, we could have to wait a little longer.
Migration journey’s end for FK8
We have good news of the migrating bird FK8, a four year old female. She has returned from Portugal and migrated to the far north of Scotland, taking up residence in the area near to Loch Slethill where she has spent the past two summers. This is part of the RSPB reserve on the Forsinard Flows, and we did send a request to the RSPB that they might assist her by putting up a nesting platform in a suitable location, but sadly they declined. She is old enough to breed this year and should she find a mate in the area – they would have to build a nest themselves, and often fail at their first attempt due to poorly constructed nests blowing out, or due to picking unsuitable locations.
Paxman osprey ‘en vacances’
The Paxman osprey, PX1, has remained in France – which was unexpected because his migration journey from Southern Mali and up through Spain and across into France looked to be typical of a bird making its way back to the UK. He landed in the Bordeaux region on 14 April and has remained there since.
The whole area where he is residing forms part of the Aquitaine basin, which drains via the Dordogne and Garonne to the Atlantic Ocean. He is currently staying on the tributary of the Dordogne, the River Isle – a 255km river which is tree-lined and in lush countryside, offering perfect fishing conditions for a young osprey. He doesn’t appear to be in any hurry to come to the UK any time soon. He is exploring the region, fishing in good rivers and roosting in trees along the river system. Seems pretty good for a non-breeding osprey to be ’en vacances’ in such an inviting environment.
A Misbelief that osprey pairs are settled
We were beginning to relax into the osprey season, safe in the belief that after the upset of losing the wonderful male osprey 8C, that at last things were beginning to settle down. We were led to believe that we had two pairs now settled onto both of the nests, with cameras on them – we had seen pairings of Mrs O with SS, her partner from last year, on the main nest and they had been mating. We believed that the widow of 8C had paired with the newly arrived (and much welcomed) bird CL1, a Borders-bred bird, in the ‘back-up’ nest.
However, it seems we have been led up the garden path by our ospreys here in Tweed Valley so far this year, because just about all we thought was true, we now find out is not at all. It is difficult when watching the live streaming of footage to discern the exact ospreys on screen, in particular the females without Darvic rings.
Footage from our osprey cameras, recorded this week
So after a week of film footage (see above) and new sightings of birds, it was time to watch the footage back in a painstaking frame by frame analysis to find out exactly who’s who in the Tweed Valley pairings!
Such a surprise was in store…
It appeared that SS had settled with Mrs O on the main nest as they had both been there, and although we couldn’t even begin to describe it as a beautiful reunion, we were at least pleased that a firm bond must exist if they were beginning a second season together and were hopeful that this bond would grow in time. They have been mating and SS has been providing fish, perhaps a little grudgingly. Then the cameras went down due to the mast link, so we haven’t been able to watch the main nest all week.
Mrs O leads the game of thrones
Meanwhile, the ‘back up’ nest camera has been working fine. We were a little disappointed to find that the nest was mostly empty, with no further sightings of the female with CL1 as reported last week. Instead a male bird arrived with a blue Darvic ring with white letters, which was believed to be FK0. He was with a female. This female was large and seemed very vocal on our camera. A BTO ring was spotted on the right leg, but no Darvic ring.
The enterprising Mrs O demanded a fish from the diminutive young FK0. He obliged and he scraped the nest out, mated with her. We wrongly thought that Mrs O was the female widow of 8C – a case of mistaken identity. So after that shocker, the footage from the previous week was then checked frame by frame, to see if we could find out which bird CL1 had, in fact, been with… and surprise, surprise…
It was Mrs O!
We know this because she only has a BTO ring on her right leg. She squawks constantly, and is a very large female with quite a distinctive forehead pattern of chocolate coloured feathering.
So now we find ourselves in the midst of an intriguing osprey drama, whereby both nests at this stage are really up for grabs, in terms of who settles down where. SS will definitely hold territory on the main nest if he is able to do so, but will he be with Mrs O? Or has she decided to flit further down the valley and hitch up with one of the younger male birds that are checking out the vacant back up nest site?
Where has she gone?
And what has happened to the poor widow of the late 8C? It looks as though she has been toppled from the nest by the very dominant Mrs.O, and yet the throne is still fair game, and open to any available male osprey that wants to take the title. But would that title include the right to take Mrs O for a bride? That could be a formidable option.
Males seem intimidated by her and adopt a defensive posture, and mostly get mobbed for fish, but will she settle at a site with a bird that can provide for her? She is checking out all the available males, and will no doubt (given that she has lots more choice now with a vacant site) choose the best male bird and nest site. She is in a very prominent position in osprey society just now.
We thought that Mrs O was a bit on the deranged side given all the squawking she does, perhaps attributing this trait to too many heavy metals present in fish she feeds on, but maybe now we are seeing a true strategy of ‘survival of the fittest’, whereby a dominant female bird has the choice of sites and the pick of the males available to her. How wrong and misjudged we can be. Mrs O is the osprey Queen of Tweed Valley just now.
What will the situation be next week?
We shall have to wait and see….
Celebrating good news
So many things can change in just a matter of a week within the Tweed Valley Osprey Project. This week is all about celebration, as we have good news from both of the osprey nests with live cameras.
The unlikely couple SS and Mrs.O
On the main nest, Tweed Valley’s star of the osprey show for the past 14 years, male osprey white leg SS, has returned. His partner Mrs O has also returned. Mrs O does not have a Darvic ring, but she has a silver BTO ring on her right leg, and her distinctive squawking could be heard long before she was spotted actually flying down onto the nest. It is an odd pairing for this couple as they met last season but didn’t have time to raise a family, but she ensured that SS fed her and they remained together. He adopts a defensive posture on the nest whenever she is around and she repeatedly calls loudly, following him around the nest. They have mated, and hopefully they will grow a more relaxed and gentle connection over the course of the summer, especially if they have chicks. There have been signs of another osprey dive bombing the nest too, but we can’t see who the raider is.
A Borders bird takes the place of 8C
The recently widowed unringed osprey partner of 8C has paired up with a new male. This is superb news, as this is a very productive nest site and the female is an experienced bird, mother to PX1 and PY1. The new male bird is one of the Borders’ own – he is a blue ringed bird, CL1, from a nest in 2012. As one of a brood of two, his sister was a large bird, about 200g heavier than he was as a fledgling. He has come to our attention a few times previously in his six years of life so far, because as a young fledgling he travelled to Ireland, to County Wicklow, where he was spotted. He has also been photographed in Senegal, and made a brief appearance to visit the Dyfed ospreys on camera a few years ago too. Perhaps he enjoys the notoriety and fame, because the nest site he has claimed as his own this year has live camera viewing too!
This is going to be an exciting time to watch two pairs of ospreys at their nest sites in Tweed Valley at the same time and be able to compare their progress simultaneously.
We have had a few teething problems with the technology to begin with but this is about to be rectified shortly and the birds will be able to be seen on the live webcam too on the Tweed Valley Osprey official blog site for Forestry Commission. They are also on camera seven days a week at the Glentress Wildwatch room and at Kailzie Gardens Osprey and Wildlife Watch centre.
It is an incredible feat of technical wizardry that allows us to view these birds, involving large distances of wireless data transmission over hills and valleys. Several masts on the hilltops need to be aligned to send signals point to point, while a power supply using solar and wind, because of the remoteness of the nest sites, adds to the difficulty of maintaining constant images. So, occasionally technical hitches require us to be patient until they can be resolved. But thankfully, we can have the pleasure of viewing these osprey nests and seeing their lives pan out as they raise their families this season.
Satellite tracked birds
We have news of satellite tracked bird FK8 and are thrilled that she has safely made it on migration back from Portugal to Scotland. For now, she has settled in the area around the Dornoch Estuary.
The Paxman osprey, PX1, has travelled safely to France and is having a break from his journey along the Garonne River in Bordeax . He has been there since 12 April and was still there on 17 April, fishing the river and roosting in nearby trees north of the river. Once the weather changes to high pressure in the next few days, that should allow him to push on further north and hopefully into the UK.
A tragic start to the season…
We received very sad news that the adult male osprey from the ‘back up’ no. 2 nest was found dead at the weekend. It was a very tragic accident, as yellow 8C dived into a pond that was netted to prevent predators such as herons taking the fish. Unfortunately, he got caught up in the netting and drowned.
Prevent ospreys flying into netting
For any land owners that have ponds which are stocked with fish and have netting to protect them, please try to discourage any diving bird such as ospreys from attempting to make a dive by creating a visual deterrent, such as bright coloured netting and tapes or flags that flap in the wind, making movement which should deter the osprey from entering.
What next for 8C’s partner?
It is so sad to lose this magnificent male bird when only last week we were celebrating his return with his partner. They had taken up their old territory and had been filmed mating at the nest site. The nest had been scraped out in readiness for egg laying. This year for the first time we have cameras on this nest, relaying live streaming of images in real time back to the visitor centres at Glentress Wildwatch Room and Kailzie Gardens. His lonesome female partner has been seen sitting at the nest with a very uncertain future ahead of her.
Satellites tracked 8C’s Offspring
His legacy will live on through his satellite tagged offspring FK8, PY1 and Jeremy Paxman’s bird PX1, and thankfully we will be able to follow their progress.
Time to find a new partner
At least the tragedy has happened right at the start of the season before there were any chicks, and it does give his partner time to meet another male this season, as birds are still arriving. We hope that she finds a partner and that the nest site remains productive. It will be an interesting few weeks to watch the nest and hope for an arrival of a new suitable male. He will have a lot to live up to, as 8C was an awesome male, a large bird with a distinctive chocolate colour, patterned, with feathering on the neck which from a distance made him look like a female.
The main nest definitely has one occupant but the osprey has only been seen with his back to the camera so far. Although we are really hoping that it is white leg SS, we cannot say for certain at this point.
We are sorry that the web camera is not yet up and running on the Tweed Valley Osprey Forestry Commission web site but we have been assured that all technical hitches will be sorted soon and there will be live pictures from both nests for the first time this year, which will be really exciting. So at this point in the season we have no idea how the ospreys pairings will turn out at the two nest sites on camera, but we just hope that they are both occupied and our birds find good partners.
We now know that FK8 has started her migration journey and the last data we had for her showed that she was on the move northwards through Portugal.
The Paxman osprey, PX1, has made amazing progress. Since the data lag in March has now been resolved, we now have tracking points to show his journey north through Morocco. He then crossed the Alboran Sea, headed east of Gibraltar and onwards into mainland Spain. Next, he flew parallel to his original southward migration route, up into the mountains of the Sierra Nevada, making use of the uplift from the thermal air currents as he continued parallel to the Spanish coast, until finally veering off in a northwards direction. He was last tracked just south of the border of France, near to a small town in Spain called Cuarte at 11.56 am on 10 April. He will no doubt reach the UK very soon and it will be really exciting to see where 8C’s son, PX1, will explore.
Will he come to the Tweed Valley?
We sincerely hope so!
Tweed Valley birds are back
Great news from Tweed Valley Osprey Project in 2018 – birds have started to return to their territories. We have the cameras set up and ready for watching ospreys at the two centres at Glentress Forest Wildwatch Room and at Kailzie Gardens Osprey and Wildlife Watch Centre.
Has SS returned?
So far, we think that the ‘back up’ nest 2 pair (8C and unringed) have returned safe and well. Birds were seen up at the nest but we have no confirmation of ring numbers yet. Ospreys have been seen at the main nest but, we have no confirmation which birds they were. We are hoping that it is SS with his partner but will have to be patient to find out for certain.
If he is back, then this would bode well for him, as a good early return could signify better luck for a successful breeding season after his disastrous season last year. Poor weather over the Easter weekend and more snow has meant nests are covered in the white stuff yet again, and no birds were seen at either nest, presumably because of this.
Jeremy Paxman’s osprey – PX1 migrating north
We are delighted to find out that PX1 the bird that was filmed being ringed on Jeremy Paxman’s programme, ‘The River’ (and hence given the ring number PX1 as Paxmans bird) has started his northward migration and is on his way back to the UK. He has spent two winters in Southern Mali, near to the gold mines at Sanso. He has barely moved from the region in that time, finding all his needs met by the landscape, which provided good roosts and plentiful fish in the lagoons and river systems.
We have contacted Jeremy to let him know the good news that his bird is on his way to return to the UK, and Jeremy said:
“How wonderful to have such an insight into the life of another creature. I’m thrilled. What magnificent birds they are!”
Jeremy will be following his bird’s progress closely, and we will send him the details of PX1’s journey as he progresses on his first return migration as a two year-old osprey.
He set off on 28 March at just after 10am and flew 271 km to roost in a remote and arid landscape with clumps of trees and bushes dotted about. He set off again just after 6am on 29 March and flew 10km further north, then he circled the area for a while before pressing on to cross the Mauritanian border and into a more lush vegetative landscape about 20km from Adel Bagrou.
We have not received any further data since then, but we can expect a lag due to there being few phone masts in the remote region from which to pick up signal. We are now very excited waiting for an update of data transmissions to find out how he is progressing.
Waiting for news of FK8
We are also waiting for an update from FK8, the female osprey in Portugal, as we would expect her to be travelling to her summer grounds in the north of Scotland too. She will be 4 years old this year, and fingers crossed will find a mate and raise her first brood.
