Best fed osprey

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

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.

A sad loss

Another week has passed and still no sign of the original female osprey. The saga at the nest site has become, at times uncomfortable to watch. The male bird white leg SS, (a firm favourite of mine in the avian world) has always been described by me as such a fine bird, a devoted and loving partner to his female. For over ten years we have watched the calm and peaceful private life played out on our screens at the two centres between the pair of ospreys. We have tried to resist attributing human emotions to their behaviour traits but this has been hard to do when we have witnessed them cuddled up together, or we have seen the male feeding the female with all the same level of gentleness that would be used when feeding delicate and fragile chicks. We have witnessed the pair making joint decisions about the layout of the nest adornments of sticks and moss and watched them present a united front against any other intruder birds.

Now that she has gone and we think that she may have died, as she would not abandon her home and family by choice, we are witnessing scenes of passively aggressive take-over. Powerful and emotive words to describe wild animal behaviour and a little over the top some may think but we have a situation whereby the male seems to be being pushed into a new partnership, like it or not.

Moving on

All he has ever known is to hold this territory over the summer and raise a family with his partner. It is what he has done all of his adult life and he is now 16 years old.
The new female has moved herself in, uninvited, I might add! She has pursued the male despite his defensive posturing, and turning his back to her. She knows this is a great site, that he is a loyal partner, proficient provider of fish, has fathered many offspring successfully and holds the best territory in the valley. She wants the nest site and she wants him! Mr Blue Leg Ring that she had appeared to be with seems to have been dumped.
I feel so sorry for White leg SS, as he seems to have no option but to stick with her. He cannot lose his territory and his own partner has disappeared. His instincts will be to try to keep the site, he cannot keep it on his own and the new female is doing all she can to make her presence a permanent one. She beseechingly calls to him when they are both there. A reluctant truce seems to be taking place as he returns to the site and instead of the usual pattern of him delivering a fish to his partner, this new bird snatches it from him, leaving him looking a little bemused. She grabs the fish from him and then flies off and he usually takes off too. This is hardly the romantic fish pass, touching talons kind of moment…it’s more of a smash and grab.

What will happen next?

We have no idea how this will develop, it’s now probably too late for this season for any more eggs, so this female has missed her chance to breed most likely but by staying with SS a bond could develop and next season, if they both make it back to this nest site, the chances are that SS will breed with her. It is also equally likely that a new pair could force them off and take over the site as their own. So all we can do is watch and see what will happen.
We are hoping that maybe we can obtain recordings from the ‘back up’ osprey nest for the rest of this season to see how that family is getting on.

Glentress Buzzards

We also have a live camera on a buzzard nest, with three chicks at Glentress and these are proving very interesting to watch. There is considerable size difference between the three chicks. The largest seems almost ready to take flight and has been seen exercising the soon to be tested pair of wings, while the two smaller chicks don’t appear to be ready yet.
One of the parents dropped in a black bird, possibly a jackdaw as food for the brood and they were seen tucking into a good meal. Buzzards do fairly well from road kills and scavenging as well as hunting and will eat a varied diet, often seen down on the ground hunting for earthworms. Not terribly raptor like or fierce really, it’s a bit of a wildlife let-down, a slight disappointment even, to see a buzzard hopping round a field looking for earthworms.

Heron takes to the skies

The heron chick at Kailzie has finally flown!  We were worried that it was going to stay at the nest indefinitely, that it was hoping mum and dad would continue to feed it. Hunger has probably driven the young bird to leave the nest and test out its wings. We watched the arrival of a young heron on the river camera checking out the slack water where the burn runs into the Tweed and we hope that this is the youngster from the nest that we have been watching.
