Highs and Lows at the Tweed Valley Nests



Three tiny osprey chicks hatched



A hat trick of osprey chicks, have hatched this week. The first osprey chick hatched on 22nd May exactly 40 days since it was laid,  followed by the second and then the third chick on consecutive days.

The chicks are so fragile and tiny looking when they first hatch, looking like tiny fluffy ping pong ball heads with the characteristic dark eye-stripe marking their osprey identity.

After hatching, they wobble about and strain to reach up to mum as she leans in to feed them with tiny scraps of raw fish torn straight from the live catch brought in by her faithful partner, white leg ring SS.

After only a couple of days the chicks begin to find strength and they are reaching up and stretching and holding their heads steady, to receive meals. They grow at a phenomenal rate on the diet of raw fish which is superbly rich in protein. Dad will have to work really hard to make sure that he brings in enough fish to feed his family, so that they will become big and strong. He is a very good provider and this is his tenth brood of chicks this year with the same unringed female. They are very experienced parents and they take great care of their young.

Tragedy Strikes



Sadly, the heron family that was on camera with two chicks hatched and one egg still not hatched, has been struck by tragedy. Firstly one chick seemed to have disappeared followed by the second chick gone by the next morning. This just left the single egg and the next day when the cameras came on, even the egg had vanished. We keep seeing the sad parent birds dropping in to the nest and standing and looking but their whole brood for the year have vanished. We did not see what happened but we have witnessed the shadowy black form of a crow lurking in the tree top and it would seem that it must have predated on the young chicks and then returned to take the egg too.

We have often made reference to the contrasting parenting skills of the two species of osprey and heron. Herons make little effort to safeguard their young and leave them for long periods of time which leaves them open to all manner of dangers. The birds have paid a high price this year for their nesting strategy. The ospreys, by comparison are very attentive to their young and there is always one of the parents at the nest to guard their brood. They will see off any threat with tenacity and this has made them the successful breeders that they are on the main nest.

The chicks will grow quickly and the daily family life can be viewed on high definition camera in real time in the two visitor centres of Glentress Wildwatch room in Glentress Forest and in the Osprey and Nature Watch Centre at Kailzie Gardens.



Possible hatching dates for ospreys and herons....

The waiting game has begun in earnest as we watch the two live screens with the heron nest and the osprey nest on camera at Kailzie Gardens Osprey and Nature Watch Centre and the osprey nest at Glentress Peel Wildwatch room. The ospreys and herons at the nest are engaged in full time incubation duties and it is fascinating to watch the behaviour and different strategies adopted by the two different species towards their nesting activities and in the rearing of their young.



Glentress Peel Wildwatch

The osprey pair at the main nest behave as a very close partnership. The incubation duties appear to be equally shared and there seem to be genuinely affectionate moments between the two expectant parents. They sidle up close together, often the male will gently nudge the female until she is persuaded to rise up off the eggs and let him take a turn at incubating.


During this period a lot of nest scraping takes place and fiddling about with sticks to move from one side of the nest to the other, possibly a way to occupy the time. It is easy to tell the difference between the adults not just because the male has the leg ring white SS but he is about one third smaller than the female and has a pure white chest, whereas the larger female has a streaked chestnut band of feathering on her chest and the markings on the back of her head crest look like a chocolate coloured concorde. 

Heron adults appear to be identical to each other, the text books tell us that the parents share incubation duties but we have never witnessed a swapping over at the nest, so perhaps this only happens infrequently. We have not witnessed any interaction between parent birds and never know if it is the male or the female that is sitting on duty. Apparently the male heron is the larger of the two but only really noticeable in wing length and beak length which is not obvious at all when they are sitting incubating. Both birds are strikingly handsome with long black head plumes and sleek grey plumage with streaked black, speckled, neck feathering. They sit motionless when incubating for long periods and often we double check that the camera is still working, when suddenly, the bird will stand and reach down to turn the three blue/green eggs.

Osprey incubation takes between 37 and 42 days and the first egg was laid on 12th April, so we can expect that the earliest likely hatching date for the first egg could be 19th May.





Kailzie Osprey and nature watch



The heron eggs were laid on 20th April, 24th and 27th April and they take 25 to 26 days to incubate, meaning that we will have live hatching on camera anytime from the 16th May. Because they have nested so late this year it will be the first time we have ever seen the heron chicks when they have just hatched. We are very excited about watching the heron chicks develop this year as we get to see the family raised right from the very start. Heron siblings behave with a great deal of rivalry and there can be many dramas, often with older siblings killing off younger ones and even eating them.



Ospreys have never displayed such behaviour in the nest in the ten years that we have watched this family. The parents are very attentive to their young whereas the heron parents have a very different approach, delivering food and leaving the chicks for long periods in the nest alone.

The camera nest box became occupied with a blue tit nest building very early in April and then all activity seemed to come to a halt. The warm sunny weather seems to have kick-started the nesting imperative and the blue tit has been seen actively nest building again, although we have not seen any eggs yet. It would appear that the cold snap has caused the blue tit to delay laying which is good because they need to wait until there is a plentiful supply of caterpillars to feed any young. Last year they were caught out by laying early and the wet weather meant there were no caterpillars. We watched as one chick after another starved and the sad image of the blue tit removing dead nestlings is hopefully not to be repeated this year. Populations do fluctuate due to seasonal variations but over time should even out.

Two eggs now and counting!

A second egg has been spotted in the nest and this was first seen late on Monday 15th April when the volunteer on duty at the Glentress Wildwatch room realised that when the female was turning what he thought to be one egg, there were actually two! We will keep a watchful eye for more eggs over the next few days.


Proud Dad to be looks down as female reveals 2 eggs


The birds have begun their incubation duties and as ever the male bird from this pair is always keen to take his turn. Both birds appear to be relaxed and very settled. The eggs are gently and carefully turned regularly and the adult birds curl their talons in, to make sure that they do not accidentally pierce the eggs while they lean down and roll the eggs into a favoured position using their beaks.

The weather has been very stormy with high winds. The female has been hunkered down into the nest cup which she frequently scrapes and shifts about material, so that it is to her liking. The male bird has been perching above the nest looking down like the proud father to be.

More wildlife news from around Tweed Valley

The pond camera at Glentress is now showing lots of toads mating in the water. The one at Kailzie has revealed masses of frogspawn and frogs lumbering about.

Breeding condition - Bright orange base to the beak

At Kailzie Osprey and Nature Watch Centre, the ‘live’ heron camera is giving superb views of the female heron in impressive breeding condition.

Her beak has a very bright colouration with a vivid orange base and yellow tip. During rest periods at the nest she has been seen resting her long beak on the sticks in the nest. She continues to re-arrange the sticks and there is a lot more fresh grassy material which has been added to the top. There has been no sign of any mate, but she certainly gives the impression of a bird with egg laying on her mind!

The first swallows appeared hunting over Kailzie fishery today and the blue tit has begun to build her nest in the nestbox with a live camera link into the centre at Kailzie.

First Osprey Egg of the Year!

Female stands to reveal egg

At just after 3pm on Friday, the female osprey laid her first egg. Two volunteers were at the centre and spotted the egg when the female stood up.

One of the volunteers is new to the project and so this is a lovely surprise for her to be the first to see the egg and a great start to the season.

We believe that this may be the first osprey egg this year in the Scotland. The Tweed Valley birds have wasted no time since their return and have been spotted frequently mating at the nest site. We will keep a watchful eye for more eggs over the next few days. 

Male flies off with fish.



At around 5.30pm, the male was up on the perch next to the nest with a fish and taking a leisurely meal while the female took her place, to begin incubating straight away. Both birds appeared to be relaxed and very settled. 



Egg rolled into position and female begins to incubate again.

 
The male flew off with his fish and a few seconds later the female stood up, peered down between her feet and began to nudge the egg with her beak to turn it, which was clearly seen. She soon settled back down to incubate again, very satisfied that all is well and the position of the egg is just as she would like it.

A variety of breeding birds at the Osprey Watch Centres

Swallows

The swallow chicks have flown the nest. It is really good to know that this family have done so well during this wet summer. We will be watching to see if the parents come back to have a second brood as they usually do. They will choose a nest site near to the one they have just occupied and start again. If they do we will move the camera and watch the next stage of summer with this pair of swallows.


Feeding stations

It is good to see that there are many young song birds coming to the bird feeding stations at both Glentress and Kailzie Gardens. The young blue tits and great tits have yellow faces compared to the white faces of their parents. The black facial markings and bibs are the same as the adult birds. Young great spotted woodpeckers, nuthatches , chaffinches and greenfinches have also been spotted.


Red list species of conservation concern

Spotted flycatchers at Kailzie Gardens


The young flycatchers and their parents are really visible down the main drive into Kailzie Gardens, you can see them perched on the post and wire fences and swooping off to chase flies and return back to the perch. A short film clip of the flycatchers filmed along the drive can be watched in the osprey and nature watch centre. The parents and two youngsters can be seen as a family together during a torrential rainstorm.


Spotted flycatchers are described as being on the red list of birds of conservation importance according to the RSPB website. These are birds of the highest conservation concern that have severely declined in population and suffered a severe contraction of breeding range over the past 25 years. We are very privileged to have them breeding successfully at Kailzie Gardens.

Good weather brings out an abundance of bird life in Tweed Valley

The good weather has meant a surge in good blue tit food with the emergence of caterpillars and we have 4 chicks left in the box which are now looking like they will thrive. Good news after the unfortunate loss of chicks earlier in the month. They are well feathered and it will only be another week before they will leave the nest and head into the woods. Hurry down to the centre at Kailzie before you miss them!

The starlings have left their porch nest at the centre at Kailzie. We never saw them leave as they often go at dawn, we can only hope that the young birds outwitted the crows waiting to pick them off! The parent birds have been popping back to the nest and we are hoping they are going to try for a second brood. If they do we will be able to pop a camera in to watch them.



Oystercatcher nesting on the stoney ground
at Glentress

There is an oystercatcher nesting on the bare stoney ground outside the Wildwatch Room at Glentress. You may think this is a particularly stupid place to nest with so many people wandering about and disturbing her but is there method in her madness? The presence of so many people around prevents the crows from coming down and is actually helping.

A note to all mountain bikers and pedestrians please keep to the paths as there are quite a few oystercatchers nesting in vulnerable places around the centre buildings.


Our two heron chicks

The two heron chicks are really big now at two months old and they flap about and wander around the nest tree, we haven’t seen any purposeful take-offs yet, so it is doubtful if they are flying yet. The parents are still bringing food to the nest where they are feeding.

A foray of feathered activity around Tweed Valley



Our developing heron chicks at the nest



The heron chicks at Kailzie are really big now and they are becoming adventurous. The nest is a midden of rotting food at the bottom and white splashes of heron droppings all around the edges. This is such a contrast to the tidy and clean nesting ospreys.

The precocious chicks are beginning to wander through the branches of their nest tree to explore their world and possibly to escape the stinky reaches of their home.

While the chicks had gone walkabout we think a chick from one of the other nearby nests in the colony wandered on in to have a nose about and see if there was any free food scraps to be had.

This bird seemed much further advanced in feathering, with the pin feathers broken all along the shafts to reveal almost full primary and secondary feathers.

After a good rummage about in the bottom of the nest, the chick then stalked off to continue wandering though the branches.

The two heron chicks return to the nest when they are hungry and mum is due back to feed them.

When their mum returns to the nest with a full crop of fishy food, both chicks violently descend on her and begin tapping at her beak to regurgitate the food. It is like a wrestling match with both chicks competing to win the prize! Most often it is the largest heron chick that wins and gets a satisfied full stomach and the smaller skinnier chick has to take any scraps dropped into the bottom of the nest. We are hoping that this smaller chick will get enough to survive.

The blue tits have now completed their clutch of eggs and it looks like there are 10 eggs in the nest. The female carefully covers the eggs when she leaves the nest but she has now begun incubating and turning them regularly. When she stands up briefly we get a glimpse of the eggs.

The feeder cameras at Glentress are bustling with hungry forest birds such as flocks of siskins tucking in to the peanut feeders. The camera is set to capture, in superb detail, these little finches teasing the food from between the mesh of the feeders.

Incubation time for our ospreys

Male and female ospreys on the nest yesterday

The camera was working again today and we are relieved that the technical teething troubles seem to be getting resolved .

The High Definition images on the live nest today revealed that the male was incubating a mystery number of eggs. He was in the nest for a considerable time before the female returned and encouraged him to move over, so that she could take her turn to incubate.

We cannot see the eggs, but the expectant parents are turning and moving them, scraping deep down into the nest cup, which takes them further from view but is doing a good job of keeping the eggs safe and warm.

The new equipment allows us to take pictures and video clips of the nest which we will update on the blog and web pages.

The quality of the nest pictures really shows just how good the new equipment is. We hope to have any initial issues sorted soon so we can bring you top quality images throughout the viewing season at the Osprey Watch Centre .

More news of returning chicks!

We have heard that another Borders bird ringed in 2007 has returned to the Borders to breed. She has a white leg ring letters EB and came from a brood of two chicks originally. She has successfully raised a family of her own this year on Tweed Valley Forestry Commission land. This is more fantastic news for our project and it is always a delight to hear that youngsters reared here are surviving their migration journeys and are beginning to return. We do not know the identity yet of her partner.

WEX Club and childrens' event.

At Kailzie Gardens there is an RSPB Wildlife Explorers Group for young children to come and enjoy outdoor adventures and learn all about wildlife. The group meets once a month and is led by volunteers from the Tweed Valley Osprey Project and trained, competent volunteer leaders from RSPB.

The next meeting will be held on 8th August and we are inviting all children who would like to get involved to come along. ( Normally it is just for members and there is a waiting list to join).

We are planning to hold an osprey day of childrens events at the osprey centre at Kailzie Gardens starting at 2pm(8th August). Please ring if you would like to book a place for your child on 07908098026.

There will be osprey arty crafts and games, including the chance to take part in creating a giant papier mache osprey head for display at the centre.

We can guarantee that all involved will have a great time!

One of our WEX leaders Aly, is pictured above, holding an osprey chick at the recent osprey ringing event carried out by the licensed Forestry Commission, Conservation Manager , Tony Lightley.

New Theatre for Children- coming soon.

The scorching hot summer is wonderful for holidays but not so great if you are an osprey mum trying to defend your brood from the sun and the chance of heat stroke.
The experienced parents of the Tweed Valley are exceptionally good at keeping their youngsters shielded and so they continue to thrive. The male is such a good hunter and has found some good fishing grounds and is continuing to bring in good sized fish for his family.
The blue tits have all fledged at Kailzie nest cam and we will be editing the recorded footage to bring you a blue tit life cycle film which can be seen at Kailzie Gardens Osprey Watch.
A childrens wildlife puppet theatre is being created at Kailzie in time for the schools summer holidays, so bring your children along to meet the characters and they can play with the hand puppets and put on their own wildlife shows.

Welcome back!

Osprey Watch centre re-opens on Sunday 4th April

We are delighted to announce that our osprey pair have successfully returned from Africa and are back on the nest and we're looking forward to this, their 7th year in the Tweed Valley Forest Park.

The two osprey centres in the Tweed Valley at Kailzie Gardens and Glentress Forest will reopen on Sunday 4th April and will be open until the 31st August between 10.00am and 5.00pm every day.

We'll be bringing you updates on the blog so keep an eye out for the latest goings-on.

An Egg at Last!!!

The long wait is over - our female Osprey this morning laid her first egg at about 11am. After days of coming and going, she finally settled in the nest centre this morning and after about half an hour of agitated behaviour she started standing and using her beak to roll something beneath her- typical behaviour with an egg.

At noon we caught a glimpse of the egg, despite the centre of the nest being so deep.
This is hopefully just the beginning of her breeding season- with three eggs the historic norm for this pair of birds. They are usually laid a day or so apart, so we'll hopefully see more eggs over the next few days.

The male has been his usual attentive self today, bringing in at least two fish- the female didn't seem much interested in the second, having more maternal things on her mind! He also tried to take a turn incubating this afternoon, keen to take a look at the egg- but our female didn't give him much of a chance! He has certainly been hanging around the nest more than usual- a proud father indeed!

A Terrible Long Wait

Here in the Tweed Valley we are suffering a terrible wait for our first osprey egg on the main nest. Though we hoped it might appear as soon as last weekend, we are sure it can't be far off now! It is certainly still in the realms of reasonable timing since their arrival so we aren't panicking yet, but the wait feels like torture!

The good news is that the behaviour of the birds is all normal and certainly the female is looking very homely!

Further good news is that out of the 8 pairs of ospreys we know nested in the Borders last year, at least five are back so far this Spring, so things are looking good for the breeding season ahead.

I have has some enquires regarding ring numbers for previous years chicks form The Tweed Valley- I am hoping to publish a list next week with all the numbers you should be looking out for! Thanks for the interest- lets hope this year we will see more of this next generation of ospreys making it back to breed here in Scotland.
