Migration update

The osprey centres may have closed for the season but the Tweed Valley osprey saga continues, with the start of migration journeys, families parting company, and plenty of drama, with a helping hand for one of the main nest chicks.

Tweedledum rescued and taken to SSPCA

The Environment team for the Tweed Valley Osprey Project continued to monitor the main nest after the season closed. They were alarmed to discover that one of the main nest chicks, Tweedledum (LL7), was spending far too much time back at the nest site, was not feeding properly, and eventually was weakened to the state of being flightless. The decision was made to recover the bird and take him to the SSPCA at Fishcross for assessment and treatment. There, he was examined by a vet and given a full health scan. He was found to be underweight, with a few broken tail feathers. After a short period of TLC, and after being fed with lots of fish to gain strength and aid recovery, Tweedledum was released back at the nest site.

Tweedledum begins to migrate

He has since got his mojo back, and on 10 September left the nest area and moved over to Yarrow Valley to begin his migration. He spent the night there, before flying further across the Borders to Minto. He then roosted overnight in farmland before heading eastwards to the coast.

He spent 3 days in the area between Craster and Long Houghton and took a circular flight out to sea, then returned inland to roost on 14 September. Then on 15 September he headed south to Warkworth on the River Coquet, where he settled and seemed to have found a good fishing and roosting spot. He doesn’t appear to be in a hurry to leave the Northumberland area and progress his migration journey just yet.

Tragedy for Tweedledee

His sister, Tweedledee, also migrated. What was so surprising is that she set off on a very similar route, starting on 8 September with a journey to the same area of Northumberland coast. She also spent 4 days in the area, and did not progress further south. The data has been scrutinised and there appears to have been no contact between them. They were never in the same place at the same time, but considering they did not leave together, the similarities in behaviour are interesting. She ventured quite a distance out into the north Sea, only to double back up to Bamburgh, and then back inland. The last data showed that she was at a business park in North Berwick at Windmill Way on 15 September. However, on 17 September we received the tragic news that she had been found dead and her carcass had been recovered in Wooler. She was emaciated and so had not been feeding. This perhaps explains why migration never progressed further once she reached the coast.

LK8’s strong migration journey

In contrast to the journeys made so far by the siblings from the main nest, LK8, another fledged bird from Tweed Valley Project area from a nest site just a few kilometres away from the main nest, has also migrated. His route couldn’t be more different to the other birds.

LK8 journey

LK8 ‘s migration route so far. He has almost made it to France on 17th Sept.

He left his nest area on 12 September and headed straight overland in a south easterly direction to Barnard Castle in County Durham, where he roosted overnight before continuing his journey to Yorkshire, then Bury St. Edmunds, and on to the coast of southern England, crossing Southend on Sea, and continuing down to finally roost near to Hastings on 15 September. In just four days, he reached the English Channel and was ready to make a crossing, whereas the main nest birds spent four days in Northumberland. It doesn’t seem that the journeys are distinct from each other due to any atmospheric conditions, but as we now know that Tweedledee has died, the delay in migration was likely due to the birds being in poor condition. Hopefully Tweedledum will do better beside the River Coquet in Warkworth before continuing his journey.

LK8 continued migration on 17 September and the last data received showed that he had almost reached the coast of France. Hopefully will have made it there in safety by now.

FK8 and Doros

Our final satellite tagged bird for the Tweed Valley Osprey Project this season is now known as Doros. It stands for Dornoch osprey, and the apt name was created by one of our volunteers, Marjorie. Doros is the daughter of FK8, one of the tracked ospreys from the back up nest in 2014. This is her first offspring but she will not be winning any great accolades for mother of the year.

Doros fledged on August 14 and after making her first flight, her mum left her at the nest and returned to her favourite hunting grounds in the Forsinard Flows. She made a 180km round trip for three consecutive days, popping back to check on her daughter, and then left for Portugal. She is now back on her territory at Sines in Portugal, yet her daughter, Doros, is still in Dornoch at the nest site and hasn’t ventured much further than the estuary or the forestry plantations nearby. Presumably her dad stayed with her to provide the final stages of parenting and hopefully any day now she will also make a move south.

Osprey season 2018

Families begin to break up

20180817_14-52-11SS and Tweedledee

SS and Tweedledee

The osprey breeding season is now drawing to a close. The birds that have successfully managed to rear young this year are beginning to separate as couples, with the females departing first from the family group, while the males tend to the offspring for the final stage.

The young have all fledged now and are at various stages of development. Most are still staying within close range of their natal sites, occasionally taking short jaunts to practice flight, following the adult male to fishing grounds, and maybe even attempting to hunt for themselves. Young ospreys will rely on their father to keep bringing fish until they are literally starved out of their comfort zone, and forced to move when the fish supply and visits from Dad cease.

At the main nest, Mrs O has not been seen for quite a while but SS has still been bringing in fish to the nest. LL6 (Tweedledee) has been seen feeding herself, at one point consuming a whole trout that he has given to her.

FK8 takes a well-earned break

nothward trips for FK8

Further north in the Dornoch area, we have evidence of the female leaving the family early. FK8 (a female osprey raised in Tweed Valley from the back up nest in 2014) has successfully raised her first chick this year, and she has been fitted with a tracker just like her mum.  Although she fledged on 14 August, she has not moved far from the nest site, apart from a few trips along the edge of the estuary and into a forest plantation.

Her mother FK8 however took an amazing ‘motherhood away day’ on 16 August. She left her daughter and headed north, back to her previous summer haunts and her favourite lochs in the Flow Country.  She was away from the nest site for 8.5 hours and covered a distance of 180km.

She travelled fast on a northward-bound journey, riding the tail wind, then caught the southbound tailwind to return along the scenic coastal route back to Dornoch. She averaged a flight speed of 21km per hour, and flew at varying altitudes from as low as 25m to as high as 626m.

She visited two lochs, and then retreated to some higher ground where she stopped for an hour. Presumably she was feeding, and perhaps sitting on top of a fence, post because the google earth image showed no visible landscape features such as trees to perch on.  She then made the long, leisurely coastal flight home to her nest. She spent 17 August at home, and will have been able to see that her daughter was doing well on her own.

The next morning, 18 August, she was off again at 4.25am with the first light of dawn. She took a direct flight back to her northern haunts, arriving at Loch an Ruathair by 6.13am. This was followed by a trip across to the east coast, returning to Dornoch by 6pm. On 19 August, it looked like she was going to stay fairly close to her nest site, but she diverted by late morning to Loch Migdale, and then on to Invercharron Woods and the loch below.

By 2.30pm she had again ventured north to her old territories, going all the way up to Loch Tuim Ghlais, 82 km north from the Firth of Dornoch. Her daughter has not ventured far from the nest site in all that time, and FK8 is away all day, only to return in the evenings. It would seem that she is keeping brief contact with the nest site, partner and her daughter, but is not providing any other support for her offspring at all.

Soon, both of these birds will migrate. FK8 spends her winters in Portugal. It will be interesting to find out where her daughter ends up, and if they have any further interaction with each other.

Tweed Valley Project Area Summary

This season has been reported as the worst year of the project since 2007, when only 9 chicks fledged in the Tweed Valley Osprey Project area. Three of the sites had birds arriving very late in the spring this year, and their partners didn’t arrive. Although later on in the season they were joined by new partners, they were too late to breed. In total, 15 nest sites were checked this year, with 11 sites occupied by 1 or more birds, but only 5 sites were successful in raising chicks, with a total of 10 chicks raised this year in the Borders.

At two of the sites, the nests and contents were blown out by Storm Desmond, and the chicks lost. One site was a constructed nest on a telegraph pole supplied and erected by Scottish Power to replace a fallen tree, but only the male returned. Later in the season he did meet a new mate, and hopefully they will breed next season.

Before the start of 2019’s season, there will be repairs made to nests damaged by storms, as well as some newly-erected nest platforms in suitable locations. Hopefully we can look forward to a better season next year.

The Darvic ring numbers that were used for this year’s osprey young for the Tweed Valley project area are LK7, LK8, LK9, LL0, LL4, LL5, LL6, LL7, LL8, and LL9. All are blue with white lettering. We will continue to update the news with details of the tracked ospreys once they start migration.

Last to go

Tweedledee fledges

20180806_11-20-32 LL6 with fish

Tweedledee with a fish

The main nest osprey juveniles have fledged. LL7 (Tweedledum) was the first to brave a flight attempt last week, while his sister was slower and more reluctant to go. The time leading up to her first flight was spent on her own in the nest, followed by a gentle feeding session with her dad SS, as he very carefully pulled off fish morsels and passed them from his beak to hers.

Once she was full, she stepped back. Mrs O quickly proclaimed her hunger and dropped down from the perch into the nest, calling loudly as she took the remaining fish from SS.  Then daughter and father pottered about for a while, cleaning their beaks by rubbing them on sticks in the nest. LL7 was absent, and missed out on a meal while the rest of his family dined. Once all the food was gone, SS left the nest and flew off, leaving LL6 at home with Mrs O.

For the rest of the afternoon LL6 (Tweedledee) undertook some serious wing flapping, with small hops and jumps across the nest. Mrs O called and squawked from the left hand perch, perhaps encouraging her to try to fly.  LL6 attempted a wing-flapping, side-stepping manoeuvre down the side branch of the perch, and a few moments later she took off at last, with mum following behind.

Mrs O attacks her son Tweedledum

Tweedledum (LL7) managed to return to the nest to feed, but his attempts can best be described as clumsy. On 8 August he was in the nest, with Mrs O on the left hand perch. She suddenly flew down and pecked at him, quite viciously and without warning.

He dropped down flat in defence and then she lunged at him, forcing him towards the edge of the nest. It seemed such an aggressive act towards her son, especially as up to now she has been such a good mum. Was she encouraging him to fly again? Or was he holding on to a bit of fish, while she was hungry too?

Balancing act

Tweedledum balances on his fish

The next day after his mean encounter with his mum, Tweedledum was seen in the nest with a fish in his talons but he was clearly not accustomed to dealing with prey by himself. He held onto it with both feet, while doing a balancing act like an amateur skateboarder, wobbling from side to side trying to maintain an upright position whilst bending his head forward and down to take bites with his beak.

He spread his wings and tail to help his balance and to protect his meal from having to be shared with mum. SS and Mrs O sat together on the left hand perch watching him while he ate and occasionally glancing skyward, as though watching something – not with alarm, or because they were unsettled. They just seemed watchful, so perhaps their daughter was close by, or flying overhead.

Fit to burst

On Friday 10 August, Tweedledum was at the nest with his Dad. He was feeding himself, and when he had finished he looked a most peculiar shape as seen from the front, with a bulging crop like a twisted balloon made animal. We’re not quite sure what happened there!

Fk8’s daughter fledges

FK8, the Tweed Valley Osprey from 2014’s back up nest, nested in the Dornoch area this summer and her daughter fledged on 14 August. The young female osprey had been making a few movements locally around the nest site, and the tracking data indicated that there was some movement around the trees nearby. On 14 August she left the nest site at just after 9am and flew to the shore of the estuary. She stayed for an hour before making another short flight and another stop, then turned to the west along the shore, finally heading into the forest plantation, flying northwards. She stopped there at 4.15pm.

Ready, Steady, Go!

Contented family life

The osprey family at the main nest seemed to be very relaxed and contented for most of the time this week. There is a very definite sense that the season is coming to an end. The young adult ospreys Tweedledum and Tweedledee are fully grown, and are ready to fledge at any time. Their proud parents have been seen sitting close together on the left hand perch above the nest. Looking like a two-headed osprey at one point, they were so close together, a scene we never would have believed possible with Mrs O, given how territorial she used to be. There is now a very close bond between the two adult birds, and SS is the accomplished dad once again, guiding his young offspring through the final stages before they spread their wings and fly.

Flight ready

Getting ready to fly

The young birds have been wing flapping and catching up on lost time during the heat wave. In particular, Tweedledum, the male bird, seemed determined that he was going to take to the skies. His sister was slightly more reluctant. She vigorously flapped her wings and teetered on the edge of the nest, looking like she was determined to go, but her feet gave her away. She was clinging on to a big stick in the hopes that it would anchor her down until she was really ready.

Her more adventurous brother really got the whole flying activity figured out, making little practice flights from one side of the nest to the other, and short, open-winged jumps to and from the perches. Before he finally attempted to leave the nest, there was a lot of balancing on the edge and peering down to the ground. The two young birds watched the scene below them intently, building up the nerve to go, and perhaps realising for the first time just how high up their nest is.

Feeding or flying

Feeding time has also been more relaxed. SS has been seen bringing fish to the nest and feeding both the young birds himself. Occasionally, feeding has ended abruptly for LL7 (Tweedledum), as he focused his attention on his wing-flapping practice instead, and left his food.

Fish must be in plentiful supply, as SS has also brought fish for Mrs O, which she shared with the young after taking the head for herself. The whole of the body of the fish was eaten by the young birds, with Tweedledee taking control of the meal before leaving a portion for her brother to finish.

Lift off for Tweedledum

Take off

Up, up and away

Finally, towards the end of the week, the serious business of flight dominated Tweedledum’s schedule, and eventually he plucked up the courage to go. His tracker showed that he left the nest at 6am on Sunday morning on 5 August. He was away, flying off above the forest and across to the edge of the plantation before coming to rest. He remained there for the rest of the day.

When volunteers came into the osprey centre on duty on Sunday they were concerned that there was no sign of him, especially when Dad brought fish back to the nest for Tweedledee and she fed herself. Perhaps the first flight was a bit daunting, and even hunger hadn’t convinced him to return to the nest until he was willing to try out his flight technique again. Those aerodynamic wings will give the bird great lift off and flight with little effort, but the tricky bit is learning to steer into landing sites, such as the nest or a tree top.

Meanwhile, back at the main nest without Tweedledum, the parents and his sister seemed unconcerned. This could have been because they knew where he was and could hear him calling close by.

No return

dad and daughter

SS and daughter Tweedledee waiting for Tweedledum to return

By Monday morning Tweedledum had still not returned to the nest site, and this was becoming worrying. His tracker had not updated and so he couldn’t be traced from his location at the edge of the forest. A quick search nearby was made, and three airborne ospreys were seen flying overhead. Knowing that Tweedledee was still in the nest, the conclusion was drawn that mum and dad were flying with their airborne son Tweedledum, and that thankfully all was well.

Right at the end of the day on Monday, Tweedledee also made her first flight, and a very brief visit back to the nest was made by Tweedledum. Since then, the young have stayed off the nest and only the parents were seen on there with a fish on Tuesday. Hopefully, they will use the nest for meal times, and we will be able to watch them for a while longer on the live camera before they leave us.

In memory of Robert

Sadly, one of our dear osprey volunteers Robert Jamieson has died. He was a great member of the volunteer team and loved the osprey project. He always gave his time so generously and made visitors to the centres welcome, telling them all the latest osprey news and updates. He will be greatly missed by all of us.

Getting ready for flight

Not long to go

The chicks at the main nest are now in their seventh week. They are fully feathered, and look chunky and healthy. With only a week to go before they are ready for flight, we might have expected to see a lot more wing-stretching and flapping to test the wings out in recent days, while they have been sitting in the nest. However, with the recent very hot weather, they have been conserving their energy until it was needed.

The weather took a dramatic change, bringing us thunderstorms with lightning and torrential rain, which gave the chicks, Tweedledum and Tweedledee, something else to contend with. Mrs O no longer has to do the motherly umbrella over her young, as their own set of feathers are waterproof now too. They just had to sit it out and wait for the rain to stop, and for Dad to bring some fish in. Fishing must have been tricky for Dad (SS), with rain dappling the surface of the water and making visibility very difficult.

SS feeds his son and daughter

SS not only brought a good fish in for his family, but he also fed the young birds himself. Mrs O is reaching the stage were her work is almost done, and she can relax her efforts a bit, as the chicks race towards adulthood and independence. SS still has a lot of work to do, and must continue to provide for his family even when the young birds fledge. He will bring fish back to the nest for them to return to and feed.

Once they are flying, the young birds will soon need to learn to find fish for themselves and master the most difficult part- actually catching them. This will all take time, and fortunately they will have back up from their Dad. It is usually the female bird that will leave the family more quickly. Mrs O will need to begin to prepare her own body for migration by building up her reserves, and getting into tip top condition ahead of her partner. SS has been continually hunting and fishing all summer, and must be very fit already, so his readiness for migration should take less time.

FK8, first time mum

FK8, the female tagged osprey from Tweed Valley that has nested in the Dornoch area has successfully raised one of her chicks. The other chick didn’t survive, but we don’t know what happened. The remaining youngster will be ringed and fitted with a tracker this week. The nest site that she has occupied is a very established site and has been productive for many years. FK8 is the new female at this monitored site.

Nobody knows what happened to the original bird but she never returned this year, and FK8 jumped in to take her place. She is possibly with the original resident male, or it could be a totally new pairing. As a first time mum, she has done well to raise one of her young to adulthood. We should hopefully have more news about her next week, and photos of her ringed offspring.

Return of PW3

We have received some backdated news about a bird from Tweed Valley that has returned this year. PW3 is a male osprey raised here at one of the original nest sites, one that has been occupied since 1998. To date 34 ospreys have fledged from this nest location, making it one of the most productive nests in the area. PW3  fledged in 2016 and was one of a brood of three, with two sisters in the nest with him.

He was spotted on his migration in 2016, 45km south west of Paris, fishing at some lakes on his way south, but hadn’t been seen since. This summer, he was spotted and photographed at Bakethin Weir, Kielder Water by Mrs Mitch Teasdale on 25 June at 6.13pm, and her husband got a great photo of him. We know that he didn’t stay at Kielder though, because on 28 June he was again spotted back on home turf in the Borders, flying and fishing at St. Mary’s Loch in the Yarrow Valley. As a two year-old male he will be looking for territory for next year. That may well be in the Tweed Valley Osprey Project area, seeing as he is spending the summer here.

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.

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.

Ringing the chicks

Main nest chicks

20180713_11-55-45say what

Twinnies – the osprey duo

This week has seen rapid development of the chicks in the main nest as they become more like little ospreys. Their plumage is now covering them in gorgeous spangled brown and white feathers over much of the body, head and wings. They have white bellies, whilst their head crest is white with brown streaks, and a ginger patch at the back, with a distinctive dark eye-stripe. Their plumage is really beautiful and much more attractive than the adult birds with their plainer colouration.

The chicks are noticeably stronger and can fully stand up on their sturdier legs, stretching their wings and flexing their muscles as they sit in the nest. Their parents have definitely done a good job rearing them so far! They will be six weeks old this week and will be capable of flight in another two-or-so weeks’ time.

Intruder alert

The parents have protected them well, including from repeated intrusion by a nosey osprey. Mrs O called out in alarm and held her wings outstretched across her young offspring, while SS stood behind her also calling out in high pitched alarm. SS didn’t feel the need to give chase though, choosing to stand his ground and join in the slanging match between family and intruder. This was enough to send the invader packing and shows the experience of the older bird SS, who knew not to waste energy on an aerial attack – especially on a bird who was probably just being nosey!

A so – so year

Further afield in the Tweed Valley Project Area, at least three nest sites have been unproductive, with birds not returning this year and others not finding a new partner.

Ringing the chicks at a Tweed Valley nest site

3Lhpe

Three juvenile female ospreys in premium condition

The successful sites which have produced chicks have been visited under license and the birds have been ringed with the unique BTO identification ring on the right leg and the large coloured Darvic ring with letters and numbers on the left leg. Volunteers from the osprey project were lucky enough to be invited to see the ringing take place at a nest site deep in the Tweed Valley Forest Park on 12 July.

The osprey parents have chosen to build their own nest and not use the artificial platform which was installed for them. They chose a really windswept and spindly larch tree for their home, and have built a substantial structure on the top, commanding a lovely clear view across the valley. Eve Schulte from Forest Enterprise had the daunting task of climbing the tree to lower the chicks to the ground to the waiting Tony Lightley and Malcolm Henderson, who hold the licence to ring birds and train the new members of the team for ringing in the future.

Trio of Females

DSC00078 3 females Lhpe cropThere were three superb large juveniles in the nest; all females. They were an impressive size and really beautiful birds. They were fitted with blue Darvic rings on their left legs, the fitted rings for each bird were LL0, LK7 and LK9. The birds were weighed and their wing lengths measured and recorded. This data is collected and used as an indicator of the sex of the birds.

Females tend to be over 1500 grammes with a wing length of more than 300mm, while the males are smaller and lighter. These females were a really good size and weight, with one being 1850 grammes, with a wing length of 340 mm. The other two were very similar. They were returned to their nest and soon settled back down. During the ringing procedure one of the parents had flown close by the site and would have returned to the young once the team left.

It will be a very short time before all three of these magnificent lady ospreys take to the skies. It was a privilege and a joy to see them.
