Tragedy strikes Tweed Valley ospreys

parents with dead chick and egg

Parents at the nest with tiny dead chick and un-hatched, never to hatch egg.

This week, when we should have been celebrating the arrival of a second new addition to the Tweed Valley osprey main nest, we are instead grieving for the loss of both the little chick and the egg, which never hatched out.

It is heartbreaking and tragic news and for a third season running, poor SS has lost his family. We had high expectations for this season, as all looked set for success. The female, although a bit unsure of what to do, was given a gentle demonstration of how to feed the little one by SS. She managed to get into the swing of things and the tiny chick looked as though it was going to thrive. She had been continuing to incubate the second egg, which was expected to hatch up to five days later than the first egg.

However, since the death of the chick and the unsettling effect this has had on the birds, the egg has been neglected and haphazardly incubated, meaning that it has had long periods to chill and is unlikely to hatch at all.

Jay sees an opportunity

The tiny dead chick was left in the nest to the right of the egg and an opportunistic jay popped down to try and steal it for a free meal. The jay was firmly seen off in a blur of wings by the female AS6, as she launched herself from the perch at the jay in the nest, while SS remained on the perch where they had been sitting together. On Monday at around 10am the adult male removed the lifeless body of his offspring. The female didn’t seem to know how to behave and brought sticks and moss onto the nest and fussed about. She was occasionally sitting on the egg and rolling it but then giving up and flying off, or sitting to the side and preening her feathers.

Why did the chick die?

We do not have any conclusive reasons why the chick died, but most worryingly the volunteer on duty heard and recorded the sound of somebody moving about near to the nest on Sunday on the live camera, after the chick had died. The adult birds were spooked and very distressed. Any disturbance that may have occurred when the chick was alive would have resulted in the adults leaving the nest and the helpless youngster would have succumbed to the cold or damp due to the weather. This would also have factored in the egg chilling at a crucial point too. The chicks are utterly defenseless when they are very young and have no way of keeping warm or dry without the protection of a parent. Disturbance remains the biggest threat to their survival during the most vulnerable stage of their lives.

We have narrowed down the time of when the chick died on the Saturday evening or early Sunday morning and there will be a thorough investigation, to piece together what happened.

It may be that the cause of death was due to natural circumstances as she was a first time mother and it can take time before she gains experience of how to defend and care for a family. However her partner SS is very experienced and has raised many chicks in his lifetime.

Disturbance of ospreys and the law

Disturbance of breeding ospreys is a criminal offence and offenders will be prosecuted.

The legal status of ospreys in the UK is a schedule 1 species under the Wildlife and Countryside Act 1981; this affords it the highest degree of protection.

It is an offence to intentionally take, injure or kill an osprey or to take, damage or destroy its nest, eggs or young. It is also an offence to intentionally or recklessly disturb the birds close to their nest during the breeding season. Violation of the law can attract fines up to £5,000 per offence and/or a prison sentence of up to six months.

The Nature Conservation (Scotland) Act 2004 widens this protection and provides additional protection for the osprey in Scotland.

Back-up nest ospreys

We hope to bring happier news about the back-up nest osprey family and how their two chicks are doing soon.

FK8’s grand tour of Scotland

FK8 is still making her grand tour of the UK and has moved from the area of Thurso that she seemed to take a shine to and has now moved further south. She spent some time in the area near to Bonar Bridge and the last data set that we have shows her travelling just south of Fochabers. She will certainly have a good knowledge of the UK landscape and good places to roost, feed or find other ospreys in Scotland, which all bodes well for when she will be ready to breed next year.

    I feel so sad reading your latest report on the osprey family, the loss of a chick and egg and the impact it has had on the parents. I am a volunteer for NTS Threave Ospreys, we have Black 80 and Blue KC on the nest and they have hatched four chicks this year. We had a scare with a would-be intruder a couple of years ago, he was equipped with climbing equipment but luckily was intercepted in time. I feel sorry for all of you staff and volunteers, we look forward so much to seeing the ospreys prosper, hope for better luck next year.

      Thank you very much, we are all devastated to lose the little chick and to watch the poor couple deal with it.

    I just realized a horrible thought what might happen that sometimes does on other wildlife cams – please don’t turn off the cam for the season now! Some bird cams decide to do that if a nest fails. The CamOps think there’s nothing for viewers to watch. I hate that. There’s always important stuff to watch. For instance, at the Montana nest here in the US, Iris’s nest has failed (there’s only one egg left & it’s no longer viable), but she & her new mate this year – Louis – have been using the tragedy to develop an incredibly strong bond. It’s been wonderful to watch. I’d love to see if the same thing happens w/ SS & his new mate, AS6. Please don’t turn off the cam before it’s time!

      I hope that it will be left on to find out how the couple behave and to continue to monitor them. Thank you

    I visited today with my parents and sister,unaware of what had happened.I had heard that there was at least one chick and was surprised to find none and one egg that wasn’t being sat on.We watched for about half an hour,trying to figure out what was going on.The female wasn’t interested in the egg and at one point did a little ‘tidying’ around it.The male was very vocal,as if trying to communicate something to his mate.We realised something was badly amiss.I agree with the contributor above that the cam should be left on.I’m sure there’s lots to be learnt from how the birds ‘deal’ with what’s happened.It’s just so sad to watch it.
