Flight of Tweed Valley Osprey FK8 during May and June 2015

FK8 has remained in Portugal but has extended her range from Portimao to an area further north.
9th /10th May. An overnight roost in the Penina Golf Course trees. This is 5km to the west of the usual haunts, along the River Arade near Portimao.

11th May, further exploration of the region, casting much further afield into a wide band north and west. After leaving the golf resort FK8 explored some of the artificial lakes in the countryside. This could be due to the summer drop in water levels in the rivers and streams.

Storks nesting on pylons and rooftops in the area of Portugal where FK8 has explored and their huge nests on the tops of the artificial poles may be a familiar sight reminding her of the treetop eyrie that she fledged from in the Tweed Valley last summer 2014.

The image above shows the journey on 22nd May. FK8 moved to the north and west of Portimao region and explored the artificial water bodies (reservoirs ) above the Rio Mira.

On 24th May FK8  made a steady journey to visit the artificial reservoir called Barragem de Morgavel. The west coastline of Portugal on the Atlantic Ocean can be seen to the left of the image above. A roost point on the lakeside is marked with a yellow ring.

The trend of movement seems to be generally northwards and seeking out large water bodies as the spring weather warmed up. If river levels were dropping then fishing may have become more difficult and hence the move to deeper water bodies with better fishing prospects.

What a difference a week makes

The chick in the main nest is growing at an astonishing rate. In one week, the change in this young raptor is very noticeable, as it is so much larger than last week, with a fine covering of feathers. There is very real hope now that this osprey will definitely make it to survive and fledge. There are times when the male brings a fish into the nest and the female shows little or no interest in taking it from him. This is possibly because he is doing so well to provide for his family that sometimes when he presents a fish, the female is not hungry and so doesn’t assume that the chick is hungry.
Sometimes he will fly off with his catch only to return with a portion of it later, having eaten a good meal for himself from it.

Shelter from the storm

The female osprey did a good job to shield the chick during torrential downpours at the weekend and was seen covering three quarters of the chicks body with her own, as the onslaught of raindrops, reminiscent of stair rods pelted down on them.

Predator versus predator

On Sunday, white leg SS brought in a pike, the pale stripes down the olive green body were clearly visible, marking it as a juvenile or Jack Pike. Even so, the length of the fish was considerable and was at least the same length as the osprey body and must have weighed practically the same as an osprey almost. With incredible skill the osprey had managed to capture a tremendous predator and not only catch it without coming to any harm but to then lift it clear of the water and carry it in his talons all the way back to the nest.

This photo was taken by Angus Blackburn in 2012 of SS bringing a smaller jack pike back to the nest.

SS bringing in a jack pike 2012, photo by Angus Blackburn

It would have made a spectacular performance to watch SS catch this fish, as pike are ferocious predators which are incredibly powerful. When in shallower areas of lochs, amongst vegetation they are ever watchful for anything which they could prey upon.  They predate on smaller fish, amphibians, even waterfowl such as ducklings and are not averse to cannibalism!

The long snout of a pike houses rows of very sharp, backward pointing teeth which make it impossible for anything within their jaws to escape. Their method of hunting, particularly in the summer months, is to lurk in the shallows and then burst forward at phenomenal speed to give chase to their victims. Ducklings’ little webbed feet would be seen from below and then the pike would strike and pull the hapless youngster into the deep. Jaws springs to mind – a very scary film  about  a great white shark grabbing its victims from the depths below. In a similar fashion, pike can be likened to the ‘Jaws’ of the freshwater loch!

The osprey hunting method is to fly above a body of water, scanning the water below with their fantastic eyesight and then ‘plunge dive’ from a great height, talons outstretched, as they drop into the water and lock on to the target fish. The curved talons would sink into the flesh of the fish like an angler’s hook and then the osprey must heave its body on outstretched wings, out of the water and become airborne again. Once it has gained height it gives a mid-air shake to remove some excess water and then arranges its toes around the body of the fish, gripping it with its talons and the Velcro-like spicules on the underside of the feet help to lock the fish securely from dropping, as it carries it away like a torpedo.

At this point, the fish would still be alive and as anglers who have ever landed a pike will know, an angry, threatened pike can deliver a nasty bite. White leg SS must have perched somewhere on his return at some point, to kill the fish before delivering it to his family, as the lower jaw was missing. That must have been quite a battle to overpower it and using its strong hooked beak to attack the fish from the head to remove the lower jaw and render it powerless.

This is raw nature, where two top apex predators meet and only one can survive. Thankfully, it was osprey that was the victor and the experience and skill of white leg SS once again is demonstrated and we can only admire him as the true champion that he is. A slight slip or misjudgement in his technique could cause him considerable danger from a pike bite.  What a privilege it is to have this mighty bird spend his summers here in Peeblesshire.

Monster sized chick

The one surviving osprey chick in the main Tweed Valley nest is growing so fast. It is now four weeks old and has a good covering of true feathers rather than the flimsy grey down which is not weather proof. The wing and tail feathers are beginning to break through along the shafts and altogether the chick looks very much like a proper little osprey now.
When food is brought in by the male bird, the chick has been fed to overflowing and the processing of all of this protein is creating a pot-bellied – but healthy looking – bird.

The lack of experience of the female bird is still apparent at times, but she did shield the youngster from the rain storm on Thursday which is good news. Both adults have been spending time together at the nest with the chick and sometimes the mum seems to lack any sense of awareness around her youngster. The female was on the perch above the nest on Monday and the chick was clearly hungry, but it was dad that carried out the feeding task and had some of the fish for himself too. As the chick reached the point of being full, the female joined them in the nest and he proceeded to tear strips of fish off and fed her.

Roomy nest

A full youngster was clearly seen to be appreciating the spacious and roomy nest all to itself early on Monday too, as it was lying down spreading out its wings and kicking its legs back into fully extended stretches. This is certainly a luxury home for one. The chick has been keeping the nest clean and always ensures that when it needs to toilet, it fires the stream of white waste out of the nest. This is often jet sprayed onto the right hand perch giving a whitewashed appearance to the branches beside the nest and the surrounding foliage.

stick moving and whitewash

Both parents were sitting in the nest beside the chick on Tuesday morning, both seemed to be highly alert and were watchful as though there was an intruder bird about or some cause for alarm but the young osprey seemed oblivious to any danger and proceeded to do a bit of stick moving around the nest, something it has witnessed its parents doing regularly as a spot of nest maintenance.

FK8 update

FK8, the one year old Tweed Valley Osprey has remained in Portugal. The bird migrated from Peebles at the end of last summer, but rather than heading all the way to Africa and along the Gambia River as most ospreys do, she stopped off in Portugal and stayed there all winter. She took a short trip across the Gulf of Cadiz in Spain in March but headed back to favoured haunts in Portugal a few days later. With the Portuguese summer well under way the fishing areas in Portimao where she was staying will have dried up considerably with dropping water levels and fish would have moved in to better areas too. We assume that because of this she moved further north in May and since then has spent her time between two reservoirs the Barragem de Morgavel and the Barragem de Campilhas.

Best fed osprey

osprey one chick fed 21st june

The osprey chick being fed

It has been a tense week watching the Tweed Valley Osprey main nest camera, as with only one remaining chick we have been worried that the inexperienced new mum may not give the young developing bird the attention and care needed to see it through this vulnerable stage of its development. Thankfully, the advantage this little one has is that when dad brings a fish in, the meal no longer has to be shared with two other siblings and that has made mealtimes a gorging fest! I don’t think we have ever seen an osprey chick fed to the point where food is hanging out of its beak before now. Struggling to swallow the last bits because its belly was just full up!

This is good news because lots of rich protein packed, raw fish will ensure growth and as the chick matures the grey fluffy down will be gradually covered by weatherproof feathers and this will help to give some protection from the elements. The female bird did protect her youngster from a torrential downpour at the weekend which was another good sign that she is doing her job properly now. She will hopefully shield her youngster from the midday sun should we ever see it again, through the veil of grey clouds that have appeared this week.

Blue tits starve

Sadly, the little family of blue tits have all perished. The cold wet weather has persisted long enough to cause a distinct lack of caterpillars which are needed to raise a brood of blue tits. Seven hatched out and one by one they have died as they have not had enough food and even one of the pretty little adult birds has died in the nest, probably worn out from its efforts to find food.

Heronry news

22nd june 2015 heron

An adult heron at Kailzie

The empty heron nest at Kailzie has been receiving visits from one of the adult herons and the bird has been doing some nest tidying. They will hold the territory until it is time to breed again but they will not attempt a second brood this year. They nest colonially in a heronry and this is a small one which consists of only five nest sites on this site.

Volunteers, buzzards and goshawks

On Tuesday 17th June, some of the volunteers were treated to a visit to watch the buzzard chicks being ringed and some impressive goshawk chicks, deep in the Tweed Valley Forest.
Licensed bird ringers from Forestry Commission Scotland, Tony Lightley and Eve Schulte carried out the task and were able to show the enthusiastic volunteers from the Tweed Valley Osprey Project these truly wonderful birds. It was an emotional experience to engage with these wild creatures of the forest and a real privilege.

The buzzard chicks were really vocal and super raptors to observe at close quarters but they were totally overshadowed by the far superior and impressive goshawk. These chicks were large, feisty and very vocal with reflexes in their talons of lightning speed. Their sturdy thick legs made the buzzard legs seem like matchsticks by comparison.

The buzzard chicks

The familiar buzzard is seen regularly throughout the Borders and feeds on carrion, earthworms, rabbits, mice, voles and birds while the goshawk which looks almost identical to a sparrowhawk but is as big as a buzzard, is a secretive, stealthy hunter which glides silently through the forest and can wheel and flip vertically in fast flight, to negotiate branches when giving chase to prey such as a woodpigeon.

Tragic news for Tweed Valley Ospreys

Two chicks in the nest have succumbed to what appears to be overheating exposure on the hottest days of the year so far. On Thursday 11th June – a really hot sunny day which is a rare occasion here in the Scottish Borders – the male bird was away from the nest leaving the female with the chicks and despite the hot weather, she was not shielding her young chicks from the sun.

Three vulnerable chicks exposed to the heat of the midday sun

When the male brought a fish in, she took it from him and fed herself, ignoring the chicks and leaving them exposed to the heat. Later in the afternoon, the male bird returned to the nest with another fish, with the head removed which he had already eaten and presented this to his partner. She was then seen to be feeding one of the chicks and the others could not be seen.

At 12.15pm the female flew off the nest and the male fed a chick. Only one chick could be seen at this point with the other two thought to be still in the nest. The next time any conclusive footage was recorded was on Friday 12th June, when one chick is seen to be active and two chicks were not moving in the nest. At this point the male brought in a fish and the female was up on the perch and she was not interested in the fish and the male then flew off with it. No interest was shown in feeding the remaining chick. It was not until 15.25pm when the male returned with fish again that the female took the fish and fed the remaining chick.

At this point many flies could be seen in the nest and the two chicks were now presumed to have died. We do not know if the bodies of the chicks have been removed as they cannot be seen but there is definitely only one remaining active chick.

On Sunday 14th June, the remaining chick was then left alone and vulnerable in the nest as both parents flew off and eventually the female returned and settled down on the nest to brood it.

home alone chick

Home alone chick

On Monday 15th June, both ospreys were at the nest and paying no attention to the one chick, the female was on the left hand perch and spent hours preening and the male took off only to return with a stick for the nest, both parents then spent considerable time moving the sticks around while the hapless youngster trundled about the nest and kept trying to get underneath mum. After their spell of nest adornment, the male flew off and the female resumed her position on the perch leaving a lonely and probably fairly hungry chick in the nest. There were so many flies around it and landing on it and at times it seemed quite feeble and then would have an energy spurt and begin waddling about. At this stage it would seem like a miracle if it survives.

15th June sticks and chick

Survival chances

With only one chick, the chances of its survival should be good, as all of the fish brought in would not have to be shared meaning good growth, but what is of concern is the lack of attention that the parents are paying to their surviving offspring. We can only watch helplessly and hope that the parent birds will resume their duties for their only one. It does further confirm our suspicions that this female is not experienced and is possibly a first time mum, as she doesn’t seem to know how to look after the young or know what she is doing.
Things went so well at this nest site for 10 years, that it is a bitter pill to swallow having two tragic years consecutively. Fingers crossed that over the next couple of weeks, the osprey pair get their mojo back after losing two chicks and put their all into rearing the one.

Blue tits

In the camera box with the blue tit family there are now only four chicks. Struggling to find any green caterpillars due to the cool spring means essential food for the growing youngsters is not available, and so one of the chicks has not made it. The parents removed the body from the nest and are concentrating their efforts on the remaining brood. The hot weather of last week would have brought about a sudden boost to the caterpillar population hopefully and this will be good news for blue tits.

Barn owls

Volunteers for the Tweed Valley Osprey Project were given a treat to visit a family of barn owls being fitted with BTO rings by Eve Schulte, Conservation Ranger for Forestry Commission Scotland.

Barn owls are another schedule one species from the Wildlife and Countryside Act which makes them a species of serious conservation concern. Their numbers in the region crashed considerably after two very severe winters in 2009 and 2010, and only now are they beginning to pick up. It was lovely to observe in close up, a brood of 3 owlets with their wizened faces, ranging in size from the large, eldest chick to the tiny, fluffy youngest. Hopefully, if the bank vole population and field mice are in good numbers this year then this little family will successfully fledge shortly. Their parents are a beautiful sight to see hunting at dusk, floating across the sky like ghostly images with their beady, black eyes peering out of their white disc faces and shrieking out their eerie banshee like calls.

Three chicks hatched

On Thursday 4th June, two tiny chick heads were spotted for the first time in the nest. It is uncertain whether they had both hatched on the same day or more likely one came a day earlier. The proud parents were very attentive and the male, white leg SS, brought in a fish which the female took and tore off small strips of meat which she offered down to each little osprey in turn to feed.

3 chicks days old with mum and Dad

Later that afternoon the male brought in a second fish and was very attentive towards his partner as he fed her.

On 6th June at 1.25pm, the female stood up and it was noticed that her brood had increased to three as the third little tiny head could be seen.

Alive and flapping

The family are doing very well so far and white leg SS, has been bringing in good sized fish. He hasn’t taken any for himself prior to delivery as he has passed over the entire fish to his partner which must have only just been caught as it was still flapping. In fact the tail end of the large trout caught on Sunday 7th June was thrashing about so much it was bouncing off the chicks’ heads.

Visitations

A cheeky jay has been seen frequently perched on the side of the nest, but both parents have seemed not in the slightest perturbed by their visitor.

The jay was picking up items from the back of the nest and eating them and then flew off with a chunk in its beak. We can only assume it must be some leftover fish. Fish supper at the jay residence must be a welcome break from acorns then! The ospreys are not concerned that these morsels have been taken from the nest and clearly don’t perceive the jay as a threat, which is strange, as the jay is certainly capable of taking the tiny osprey chicks at this stage of their life. Maybe, the clean-up operation to remove fish debris discarded by the osprey family is welcomed for now, particularly as the chicks would never intentionally be left alone while they so small.

Hatching expectations

swap over main nest

We are expecting the osprey chicks to hatch this week, after a long incubation period of 35 to 40 days, little chicks should break their way out of the eggs were they have developed. They have a small tip on their beaks called the egg tooth; this is a tool that they use to chip the eggshell open from inside of the egg. They lose the egg tooth soon after hatching and begin to feed on raw strips of fish presented to them by their mother.

Intruder alarm

There was a bit of a shock this week as there was the unexpected appearance of a third osprey at the nest on Monday, this cheeky intruder briefly flew down into the nest, next to the incubating female but thankfully, white leg SS, was close by and immediately did his job and came straight down into the nest and then chased off the intruder. It happened so fast that we couldn’t see if it was a male or female bird. SS was away for about 10 minutes and for the whole time, the female looked very unsettled and alarmed. She was very alert and with her head up, looking skyward – presumably there was a bit of sky chasing above her that we were unable to see.

He returned to the nest and landed beside her and then was quickly off again and the female was alarm calling once more. He must have been successful in chasing the intruder away, as he returned and things settled again. Later he left the nest once more but the female looked content and so he had presumably gone off to hunt for fish.

Vulnerable chicks

Being so close to hatching, this week and the first couple of weeks after the chicks have hatched, is the very worst time for upsets, such as intruder birds, as the chicks will be at their most vulnerable stage. When they first hatch they can barely hold their heads up and are very wobbly until their muscles begin to develop and they gain in strength as they quickly grow on the protein rich diet of fish.
We are apparently due a bit of warm weather which will be a help for the young family, so that feeding can take place. The female has to stand up and away to the side of the chicks to feed them, which would be an impossible task in the high winds and torrential downpours of late.

CL6 after ringing

Return of anniversary young osprey

In 2013, we celebrated the 10th anniversary of the main nest pairing between white leg SS and the unringed female. As part of that celebration we worked with the children of St. Ronan’s Primary School in Innerleithen, to produce the book ‘Time Flies’, to tell the story of the Tweed Valley Ospreys.

The children were treated to a visit to the main nest site to see the young ospreys being fitted with their Darvic rings and the ringed birds were CL4, CL5 and CL6. The rings were chosen to correspond to their class name P4/5 and the following term they were to move to P6

This week we received a report from Joanna Dailey from Kielder Osprey Project that CL6 was photographed at Bothal Pond in Northumberland on 30th May 2015. Here is a photo of the bird taken by Frank Golding and published on Bird Guides.
The bird was watched for about 10 minutes, getting mobbed by crows and oystercatchers and then headed off to the east.
The school has been informed about the birds progress and hopefully the children will be really pleased to know that this bird that they saw as a young fledgling, is now a migrating adult and is fit, looking good and back in the UK.

CK2curtesy osprey safari

CK2 Esthwaite safari

More news has been received from Dave Coleman about the Tweed Valley bird CK2, at Esthwaite in the Lake District. She is in fact breeding and a photograph of her with a male ringed bird was sent to us. The picture is not clear enough to make out the identity of the male but more news about the birds there can be found on the Osprey Safari Facebook page.

FK8 is scouting in Portugal

FK8, the year old Tweed Valley satellite tagged osprey, has moved from her winter quarters in Portimao in Portugal, to a more northerly part of Portugal close to Sines. She is ranging across long distances and scouting and exploring the area. With summer well on its way, the Portuguese river levels will have dropped significantly and fish will have moved to deeper waters and maybe it is this reason that she is now seemingly fishing reservoirs and deeper waters.

Blue tits hatch

The blue tits in the camera box have hatched at Kailzie and the tiny bald nestlings are simply gorgeous. Mum and dad are working hard and delivering green caterpillars to them.
The mystery, slowest nest builder ever, seems to be adding a bit of moss regularly to the other nest box camera but it may be too late in the season for it to be a viable nest for raising a family.

Goshawk family

Fantastic new footage of a goshawk family has been added to the Glentress viewing facilities in the Wildwatch Room. This is a real treat to observe this shy and impressive rare predator.

Peaceful incubation

The long wait for the incubation period to come to an end seems tedious to us but for the resident ospreys at the main nest eyrie, life has become routine and fairly steady. If ospreys were thankful creatures I am sure that they would be grateful that they are not being harassed by other ospreys wanting a nest site. They seem to have been left to get on with their breeding season with little intrusion so far from other ospreys this year. Could this be because they are a new pairing and the female is strong and young, therefore presenting themselves as a force to be reckoned with? Do other ospreys intrude and cause bother only when they believe they are in with a chance to usurp a weaker individual? It is purely speculation but given that so many established pairs of long standing have had intruder birds and eggs kicked out of nests by rival males at other UK sites and the problems we had last year with our old female, it is a possible consideration.

Hatching time

There is not long to wait now for hatching time and we expect little osprey heads popping up in the nest sometime in the first week of June. This is an exciting time for the Tweed Valley Osprey Project to witness on screen the behaviour of the new mum with the very experienced older male. He has 11 years’ experience of being a successful father and rearing chicks to fledge. We are speculating that this is perhaps the females’ first brood.
Much of her time is spent preening her feathers while he is sitting on the eggs. The breeding season and the long wait for eggs to hatch is an opportunity to moult and grow some pristine new feathers.

A cheeky little female chaffinch took a wander across the top of the nest while the female osprey was incubating and she seemed to help herself to a bit of moss from the nest to take back to line her own nest presumably.

Blue tits

The blue tits on camera at Kailzie now seem to have a complete clutch of eggs at seven in the nest. This is less than most years and is also later than usual due to the cold delayed spring.

Return of the spotted flycatchers

We are delighted that spotted flycatchers have built a nest in the open fronted nest box with a camera on it. The last time they used this box was in 2007, we recently cleared some branches from the area in front of the box and it seems to have been just the right thing for the flycatchers. Flycatchers apparently like a completely clear flyway into their nest site because branches could become perches for predators to use to look into the nest.

Wild food at Kailzie

A Wild Food at Kailzie event will take place on Saturday 30th May from 11am to 4pm in the gardens, with a chance to discover what is edible and growing around us. There will be pond dipping to look at natural predators feeding in the ponds and song birds will be getting a treat as Lynn Walker will be building the Feasting Tree which we hope visitors will help to fill with delicious bird tucker. Come along and make some delicious pudding for birds to feast on and make a feeder of your own.

There will be children’s games and also some live bird ringing taking place in the osprey centre where there will be a chance to see songbirds close up before being fitted with a BTO ring and released unharmed. Donations collected on the day will be for the Tweed Valley Osprey Project.

On the move north

The satellite tagged osprey from Tweed Valley is on her travels again. Having spent what seems to have been an idyllic winter in Portimao in Portugal she briefly took a trip to Spain almost as far as the Strait of Gibraltar in March and then returned to her favourite haunts in Portugal where she has been settled ever since.

full journey of FK8 to May 11th 2015

However, with the onset of summer and the rising temperatures causing river and water levels in general to drop, the osprey, one year old female has begun to move in a northerly direction following the coastline of the Atlantic exploring water bodies in the form of reservoirs and the larger Portuguese rivers. She was last tracked at the Barragem de Morgavel near to the Rio Mira on 25th May.

Dad the incubator

The novelty of carrying out much of the incubation of her eggs by herself has worn off for our resident female osprey. We suspect that she is a young, possibly even first time breeder and she was so pleased with her fine clutch of eggs that initially, she was resistant to allowing white leg SS, to take a turn to incubate. Well a few weeks of the endless sitting and nothing much happening, must have played a part in changing her mind, as she is now taking extended breaks and leaving a bemused SS alone to incubate.

On Monday 18th, male SS was alone in the nest and sitting on the eggs for most of the day, he was there when the cameras came on and he did not get relieved from his duty until 3.15pm.

The next day, once again, white SS was on incubation duty for most of the morning until just before midday he flew off and she returned within a couple of minutes of him leaving and took over. She had just settled down after turning the eggs and rearranging some nesting material when an almighty hail shower burst. A very fed up looking osprey could be seen hunkered down low with hail stones literally bouncing off her back.

hailstones cropped

They have a few more weeks to go yet before hatching time. The earliest likely date for hatching would be from 3rd June to 7th June.

Intruder ospreys

Now that the pair are established this season, there seems to be a more settled atmosphere at the main nest site and although we have seen an occasional alarm calling and the shadow of an intruder bird flying over the nest, most of the time they seem to be left in peace.
It is thought that intruder birds played a part in the downfall of the previous female which led to her leaving the three young chicks to die in the nest last year, as there were certainly other birds about and the new female wasted no time to move into the nest site, the very next day after she had gone.

Other osprey sites around the country have not been so lucky this year with eggs being kicked out of the nest at Loch Garten by an intruder male bird and Kielder nest sites have had multiple intruder birds harassing the resident pairs. Luckily their eggs have not been damaged. One of the intruder birds causing mischief was a Kielder returning youngster.
When intruder ospreys check out nesting pairs they possibly assess the situation and size up the competition. They may be seizing upon the chance that one of the pair may be a weaker or aged bird that can be displaced to make way for them to move in on a nest site with a resident bird in breeding condition that holds a territory. It has certainly worked for our new Mrs osprey and it would seem that another bird is trying to push out Odin the male at Loch Garten in a similar fashion.

When ospreys fail to breed they often build another nest close by (known as a frustration nest), we do not really understand the purpose of this nest. Is it a ‘back up’ nest in case they lose the territory of the one they hold and they intend to use it themselves, or is it to perhaps distract intruders away from their site and hope that they may take that nest instead?

The number of intruder osprey incidents causing nest upsets and failures is perhaps a good argument for putting up some more artificial nesting platforms to provide an opportunity for a pair in breeding readiness to move straight in.

However, some healthy competition for nest sites may be of benefit to the breeding population too, in a way that osprey breeding success comes from the strongest and best birds in their prime, as the weaker ones are driven off site. Survival of the fittest ensures that the weaker, sickly birds do not get to breed and therefore the offspring are perhaps born to only the best of the osprey stock.

2012 brood

Tweed Valley returner

A Tweed Valley osprey has been reported to have been seen at Esthwaite Water in the Lake District this spring. It is a ringed bird, CK2 which is one of the birds which fledged from our main nest in 2012. Great news that CK2 has made it back to the UK successfully and has been seen and we are waiting to hear more news about whether the bird was just passing through or if it is nesting there.

Bird box news

Blue tits have had a slow spring due to the weather but the pair that have moved into the nest box at Kailzie now have seven eggs and another box which we had assumed had been abandoned had some new nesting material today, so it looks like a pair of late breeders are ready to move in.

Sparrows have moved into the sparrow box on the outside of the osprey centre building, these birds like to nest communally and at least two pairs have moved in.

At Glentress the house martins have been very busy near to the pond area outside the Wildlife Watch room and they are taking advantage of the rainy weather causing messy puddles where they are gathering beakfuls of mud to build their mud cup nests which must be in the houses below Glentress judging by the direction the birds are flying off to.

Three eggs

a fine pair 11th May

We can now confirm that the main nest pair have three eggs and the long process of incubating them has begun. White leg SS and his previous partner of 11 years had the whole egg and nest ‘set up’ managed like a well-oiled machine. They took turns to incubate and the female would get long breaks away from the nest, while SS took his duty of sitting, in her absence. The new Mrs SS could possibly be a first time breeder, she is unringed, so we do not know her history but her behaviour sometimes suggests that this is quite a new experience to her. Certainly, he is a new husband but she seemed to be a little slow to take up her duties in the beginning when the eggs were first laid. However, now she is into the swing of things, she is at times reluctant to leave at all. White leg SS would drop down from the perch into the nest and was there to take a turn but she didn’t budge at first. Over the past few days though, hunger and perhaps a need to take a stretch, has forced her to allow him some incubation time and they seem to be getting more familiar with their new routine.

We already know that SS is a super dad and has previously raised 10 broods safely through to adulthood and we hope that the new partner will prove to be a really good mum too. Even if she is inexperienced, she will soon learn how to look after her chicks when they finally hatch, which will be in mid-June.

Traffic stopper

On my way to the osprey centre, travelling along the A72 on Tuesday 12th May at just before 9am, traffic flow was interrupted by road works and a convoy system, involving a long wait to get going again. While sitting in the queue of traffic at a standstill, I got a fantastic view of an osprey fishing along the River Tweed right in front of the Cardrona Village Store. The osprey was being mobbed by a pair of crows and three common gulls but was determined to carry on fishing. It continued along the river towards Peebles and I was disappointed when the convoy started off and I had to drive on!

Oystercatcher island

The tiny island roundabout at Cardrona is home to the nesting oystercatchers again this year. On a small scrape of shingle in the island, the bird is sitting on eggs and her partner often sits on the road bollard like a little black and white sentry guarding his mate. The same crows that were giving the osprey a hard time, unfortunately seem to be watching the oystercatchers too. They did this last year and after a long term of incubation,  the eggs and birds where gone, nobody saw them hatch or leave and so we were never sure if they hatched and were led quickly to safety by mum and dad or were gobbled up by the waiting mobsters. Perhaps they were successful, seeing as they have chosen the same nest site again.

A pair of oystercatchers have been checking out the ground in front of the Wildwatch room at Glentress and looked like they were prospecting for a nest site too.
First spotted flycatchers

On 12th May the first spotted flycatcher was back at Kailzie Gardens and had taken up its old hunting ground along the main drive. It likes to perch on the fence posts along the drive, taking acrobatic leaps into the air and giving an aerial chase after flies and then returning to its perch.

Osprey FK8

The Tweed Valley satellite tagged female osprey is still in Portugal, around the Portimao region of the Algarve. Her movements are concentrated in the area around the River Arade and the reservoir to the north of the region.

Penina golf course roost

In early May, she ventured across further to the west to check out and roost overnight in a large Penina golfing resort. As the Portuguese summer progresses many of the smaller river tributaries dry up and the estuarine waters become hard saltpans so we may find that FK8 will move on again. We will have to wait and see what happens. A full round up of FK8’s latest movements will be posted soon.
