Another lovely day at Loch of the Lowes with typical April sunshine and showers! Both our ospreys are continuing to incubate and strangely there haven’t been any fish deliveries to the nest during the day- it seems our female must be fishing for herself during her breaks off the nest. This is not unheard of but interesting- perhaps a bit of a role reversal? She almost landed on top of her mate this afternoon and gave him a good fright too- strange!

The male made a mistake when he left the nest to chase an intruder. When the old Lady returned after a few minutes it was too late and the crow had a tasty osprey chicken meal. :cry:

:hi: Thanks Ferenz for sharing pics.
It is very sad that this year no chicks are hatching.Nature go here own way. I only hope that will be not the last time i see the Lady.
Lady and Laddie are sitting on eggs all time and they given not up but the time is over. Now we must see what happened in future .

I found this video on Youtube it is the nest in Tweed Valley Ospreys. The same situation i saw in the nest by Lauma and Perkon. I think that behavior is not so seldom in the world of ospreys. :nod: Feeding chicks is going "hand in hand". It is so lovely.

Osprey Diary 26th June 2014
Osprey Diary 26th June

Posted on June 26, 2014 by rangeremma
Our ospreys have now incubated their unsuccessful eggs for a staggering 74days to no avail. This shows just shows how remarkably persistent and dedicated they are as parents and just how strong the instinct to incubate is in birds such as these.

Many people have been asking why they haven’t give up incubating yet: The answer is that the birds don’t have an access to an accurate calendar, so they will continue until any possibility of hatching has passed, possibly when day length has changed so much they can tell it is obviously too late. There is also the possibility that they now know the eggs won’t hatch, but don’t know what else to do with them- the instinct to nurture is so strong.

I have also been asked a lot why they birds don’t know the eggs are infertile? Unless the eggs are badly damaged , they won’t smell rotten even if they are a bit addled inside. Both adult birds have been listening to the eggs , and by now must be aware that there is no chick noises from inside.

It is clear over the last 2-3 days that our birds behaviour is changing and they are finally beginning to loose interest. For the first time the female hasn’t incubated overnight every night as normal, and yesterday she sat almost the whole day on another nearby tree, not on the eggs.

Therefore we have decided it is now the right time to intervene and remove the eggs for scientific analysis, before they are further damaged or stolen by crows etc. This will hopefully give us some clues as to why the eggs haven’t hatched.

So if you see our professional climber Sam on the nest camera today, please don’t panic- he’s operating under license and will be as quick and careful as he can to minimise any disturbance to the adult birds. Every year our female osprey has a climber at her nest to ring her chicks and is usually remarkably tolerant, circling overhead and calling but not being overly aggressive, so we would expect her reaction to be the same.

Sad ending.

continued;
5pm Update:

Thanks to our SWT climber Sam ( to whom we owe a big thanks!) the unhatched eggs have been safely removed today from the nest. The birds were remarkably unfazed by the intervention and though the both circled overheard for a while there was remarkably little alarm calling and certainly no aggression. This is in marked contrast to the females usual constant alarm calls when we usually approach her nest to ring chicks.

The eggs themselves have both been found to be intact- no signs of cracks or holes in them or damage that would have been sustained in the crow attack earlier in the season.

We will now be taking the eggs to the National Museum of Scotland’s Ornithological Curator for further analysis to see if we can get any answers to why they haven’t hatched.

Osprey Egg News 8th July

Posted on July 8, 2014 by rangeremma

Our ever helpful friend at the National Museum of Scotland, Bob McGowan , has taken a professional look at our osprey eggs which were removed from the nest after the birds gave up incubating unsuccessfully for 74 days.

Our initial observations were that one egg ( the rounder one) was much smaller than average and only weighed 39.1gms, whereas the oddly elongated one was a more normal weight of 52.9gms. By contrast last years unhatched eggs weighed 46.9, 49.8 and 50.6gms.

Both eggs were intact and showed no sign of structural damage, ruling out the crow attack as the cause of hatching failure. The eggs were candled- a light process similar to xray- and it was immediately obvious that there were no embryos inside either egg. In other words, there were no partly developed chicks inside , and the couple of incidents when the male osprey left them alone and cold for a period during later incubation can also be ruled out as the cause of hatching failure.

The eggs were then carefully blown- the rather smelly contents removed and examined closely. One egg ( the smaller round one) was completely ‘blank’, and had not been fertilized at all and had begun to dry out. Unfertilized eggs are common in nature and we have had instances of this before in this nest.

The second, longer heavier egg had a few spots of blood among the fluid, which means it was fertilized initially but development probably stopped at a few days, very early in the incubation period. We cannot say why this happened , but again this is not unusual in eggs when an embryo is not viable or conditions are not right.

So the conclusion to all this is that the cause of our breeding failure is a fertility issue, rather that any fault during incubation. By far the most likely cause of this is our female ospreys advanced age , though there is a slight possibility that it might be the male who has the fertility issue ( he could be firing blanks so to speak) or that we have a case in in breeding depression ( a term scientists use to describe the low fertility of a pair of animals who are too closely related and therefore not a good genetic combination and don’t produce many viable offspring) .

We cannot blame either bird for the lack of breeding success this year, but we have to accept that this pairs fertility is now been low for 3 years and may always be so.

Lastly, what was fascinating as ever was to see our eggs in the context of the reference collection in the museum with ospreys eggs from all over the UK- there was a fascinating wide variation in colour and size of course. What was truly heart-breaking though was to see at least two full clutches of osprey eggs that had been robbed by human egg thieves from nests not 5 miles from Loch of the Lowes in the 1990′s. These had ended up in the collection after the thieves had been caught and prosecuted and their collections confiscated- how sad that these may well have been the potential offspring of some of our birds descendants, cruelly denied the chance ever to hatch. What a sad reminder of why we still need to do osprey nest protection watch and how close the threats have come in the past to our precious birds.

A Spiky Tale: Hedgehog Rescues at Loch of the Lowes

Posted on July 23, 2014 by rangeremma

This month began with a bang, not only did the volunteer assistant rangers and I get our first sighting of a pine marten, but we also came across a wee hedgehog looking rather lost and confused in the road. We observed and watched its behaviour for some time to decide whether or not it was a true orphan and required rescuing. It soon became apparent it was not alone as we were being watch by a very still, but super alert adult hedgehog on the wall above the road. First thoughts were that the juvenile had fallen from the wall and couldn’t find its way back up to its mother, but it is very unusual for hedgehogs to be out during the day as they are nocturnal creatures and spend their days sleeping in a nest. A few steps on and the story unfolded, as a second juvenile was found frantically running up and down . This now began to look more like a case of possible nest disturbance – possibly by a person or dog or accident when nearby farm equipment was being moved. Juvenile hedgehogs live in family groups in nests and tiny babies will only leave a nest if there is a problem or when they are at weaning age and ready to learn to forage for food at night. Young hedgehogs will make a very shrill, loud, call if they are in distress and this is exactly what we began to hear.

Hamlet the Hedeghog
Hamlet the Hedeghog

Did you know? In hedgehog families the Males have no role in rearing the young called ‘urchins’. The female gives birth, after a 35 day pregnancy, to typically 4-5 babies. She will have prepared a nest as a nursery under a hedge or in a pile of leaves, or frequently a shed or outbuilding.

In this case it appeared their nest had been accidentally disturbed on the local farm and sadly 2 other siblings had already met their fate on the road. So the luckier two juveniles and adult hedgehog were picked up, with the plan to release in a safer location after dark that evening.

When and how to assist a hedgehog

A hedgehog is in real trouble if:
◾ The hedgehog is out during the day, and is looking wobbly or disorientated.
◾ The hedgehog is asleep away from its nest e.g. lying in the middle of a garden or path during the day.
◾ It is a single orphan on its own- after surveillance to check if mum is around.
◾ Once you have established that a hedgehog is in need of aid, pick it up with thick gloves and put it in a cardboard box with newspaper and an old towel. Thick gloves help, as their spines can hurt and they sometimes bite, it also prevents the transfer of human smell.
◾ If the hedgehog is very dull/flat a hot water bottle wrapped in a towel, (or any plastic bottle filled with warm water), can be provided. Ensure the hedgehog has ability to move away from heat if it becomes too warm.
◾Do not try to force the wee hog to eat or drink – this can be traumatic and keep handling to an absolute minimum to prevent stress.
◾ A small bowl of water should be provided and then contact and take the hedgehog to a professional wildlife rehabilitator.
◾Always get expert advice on what to feed your hog- the wrong food can make them very very ill.

At dusk we attempted to release the hedgehog family, the adult female and one juvenile did set of from the box foraging and finding their way, but sadly the smaller of the two juveniles began a high piping distress call and circling frantically. It was therefore decided that he needed to be assisted and after initial first aid from the staff here at Loch of the Lowes he was taken to a professional wildlife rehabilitator.

Rearing of orphaned hedgehogs is not easy and should be undertaken by wildlife trained individuals. If you uncover a nest with urchins (young hedgehogs who have not been weaned and usually have very few spines) you should not disturb it, but covered over again and left. The mother will usually return, if there is no human scent on the babies.

If you are ever unsure about what to do contact your local specialist wildlife rescue centre for advice or the SSPCA 03000999999 or RSPCA 0300 1234 555 .

The happy postscript to this story is that “Hamlet”, as the smaller hoglet was named, has progressed quickly in care and has now been successfully rereleased here on the reserve to re-join his family. However, another unrelated wee hoglet was also found on our footpath by a member of the public last week and so we had to repeat the whole process- but this wee one is also doing well.

All's well that ends well. :shake: PS photo of Hamlet didn't copy. :mrgreen:

Wildlife Diary July 29th: A plea to drivers
Posted on July 29, 2014 by rangeremma

Here at the Scottish Wildlife Trust we strive to protect and encourage wildlife of all sorts, from the large and glamorous species such as Ospreys and Pine Marten, to the wee cuddly things like Red Squirrels, beautiful things like butterflies and dragonflies, right down to the less glamorous but equally important invertebrates, amphibians and underwater life. We do so much work protecting , surveying and improving habitats for wildlife, it breaks our hearts when there are unnecessary losses from preventable causes- the worst being road casualties.

Unless you’ve been lucky enough to visit the Loch of the Lowes reserve, you may not realise that our beautiful loch has a small rural road running along one side. This one lane road has the reserves lochside woods one one side and our neighbours arable fields along the other so wildlife are often attracted across it.

The sad fact is that this road has seen a high number of casualties every year, and this year has been especially bad. Since January this year we have lost:

1 Fallow Deerred squirrel

4 Hedgehogs

2 Red Squirrels

3 Brown Hares

1 Tawny Owl

1 Oystercatcher

1 Mallard Duck

5 Pheasants

Dozens of toads, frogs and mice.

Please take care this summer for wildlife on the road- this time of year there are lots of young animals out and about who have very little experience and can be especially vulnerable. Dawn and Dusk are the worst times for wildlife on the road so PLEASE SLOW DOWN especially near woodland areas, and near ponds, lochs or rivers. thank you!
