First flight

Proud parents

Last Monday 27th July, myself and RSPB ranger John Clare witnessed the first ever flight of our eagle chick. The eaglet was due to turn 12 weeks old the following day and we’d usually expect chicks to fledge at around that age. We watched our youngster fly over the forest near the nest site, surprised to see the first flight going so well. The eaglet even managed to twist over in mid-air to threaten a buzzard which was coming too close! This flight backed up our thoughts on the sex of the chick, we’re pretty sure that she is a female due to size (females are up to 25 per cent larger than males). Throughout the day we enjoyed views of her back on the nest, she spent all day exercising and preening on an outer branch – maybe that flight was enough for one day! The adults, Iona and Fingal spent some time near the nest site for the afternoon and we witnessed them perched very close together looking very much like a couple, something we don’t see very often.

Crash landing

After such a good first flight it couldn’t all go swimmingly and we watched the fledged eagle crash land into conifer trees near the nest a few days later. She had been attempting to land on the nest itself and badly misjudged. This is natural and is all a learning process, it’ll take some practice to fully control that large wingspan, especially when dealing with trees. Since then she has spent some time down on the ground in the grassy clearing below the nest site. The weather hasn’t been great and may be making her reluctant to try flying again. The eagles look very vulture-like when they’re on the ground, demonstrating that they’re actually closely related. The image below is of Thistle, last year’s youngster, raised in the same nest site by Iona and Fingal. This is what our current eaglet will look like, although I’ve not managed to catch a photo of her yet!

Almost autumn

Trips will be running throughout August, and John is likely to continue running walks to look for the eagle family into September and October. My position ends mid-August, so I will be leaving at a time when the fledged youngster is learning how to survive and find food. The chick will probably stay with Iona and Fingal into October or November, and will then begin to roam wider areas. This a natural process, eagles will cover huge areas in the first few years of their life. White-tailed eagles reach adulthood at around five years old and will then settle down to create their own territory. During the sub-adult stage white-tailed eagles are fairly gregarious and often form social groups or roosts, especially during the winter. So if you can brave the wintery weather, our colder months are a perfect time to watch eagles in the UK. Along with white-tailed eagles, Mull wildlife throughout autumn and winter is incredible – otters and golden eagles don’t go anywhere, and in addition we gain many wintering bird species. Believe it or not, we’re already on the lookout for migrant birds and we’ll notice some of our summer residents leaving soon too. And we haven’t even had a summer yet!

Drastic deer

On most of our trips we’re seeing large numbers of red deer through the telescopes. These animals are mostly feeding higher up on the hillsides during summer in an attempt to avoid midges and flies. Red deer are a native species to the UK and are the largest species of deer we have, but due to the loss of our native predators like wolves, bear and lynx deer species are now present in very large numbers.

reddeerThey’re always a pleasure to see and at this time of year many of the stags are still growing their antlers, which are covered in velvet for now. Deer antler is one the fastest growing materials in the mammal kingdom, increasing by 1cm per day! Despite being a great sight, deer numbers do need to be controlled, as they cause many issues within our ecosystems. In large numbers with no predators, they prevent natural woodland regeneration, damage heather moorland and shrub and increase erosion and flooding. They can also cause real damage to timber plantations across the UK. The survey figures suggest that on Mull alone we have around 12,000 red deer. We also have some small pockets of fallow deer (a non-native species).  It won’t be long until the deer are moving to lower ground for the deer rutting season. Again, another great reason to visit Mull in the colder months. September and October here go by to the sound of roaring and rutting stags.

Fledged but not flown

The busy, busy period of country shows and beach games is just about over now, with Lifeboat Day tying it all up and the Scottish children are now back to school. This last month has flown by even faster than all the rest.

Adult white-tailed eagle (John Clare)
Our female juvenile is doing well after fledging although she still hasn’t gone all that far from the main area of the territory, near the nest. All of this wet and windy weather won’t have been much encouragement to get going so she’s spent a lot of time sat on the grass below the tree line looking wet and miserable. She has managed some good flights above the forest but she’s always managed to come back down in her well known area.

Mackerel & gannet bonanza

It seems that Iona and Fingal are fairly frustrated with her and spend a good amount of time nearby giving her a glare of parental annoyance; they still want her to make her way to their prime hunting territory over the loch. Despite this, they’ve still been bringing in prey and often spend time down on the grass alongside feasting together. We’ve had great sightings of feeding behaviour with prey items like mackerel featuring a lot – this matches anecdotes of people catching 100 plus in no time at all around the Mull coastline.

We also had some visitors this week that have been enjoying a spectacle – white-tailed eagles hunting gannets! I always say they can and do, but I’ve never been lucky enough to witness that yet. Gannets have a wingspan of 2m, they’re a huge bird in their own right and they’ll be busy feasting on the glut of mackerel.

Awesome autumn

Despite it only being August the air has a distinct autumnal feel. Rowan berries have burst into colour and hooded crows among others have been making off with large beakfuls. Leaves are turning and falling, on a woodland walk yesterday I was trooping through falling leaves of sweet chestnut and oak. We’ve had a rush of poor weather too, with some strong winds and torrential rain, feeling much more like September than August! Not that I’m complaining, autumn is a great season and one of change. Everything is busy, on the move or collecting up fat stores and caching food.

I was treated to a family group of Jay yesterday with their harsh call, they’ll be preparing for winter now and beginning to cache food, they have an extensive territory map and a brilliant memory. I’m looking forward to hearing the first fieldfare crossing overhead and seeing the familiar v-shape silhouettes of wintering geese.

Winter prey

Eagles and other top predators will begin to change their main prey items as the seasons change too. Fish like mackerel will move off, for example, but other prey becomes more important. Beginning late September and into October our largest deer species begins its annual rut for dominance. The stags don’t fed throughout this period, so many lose fat and stores and many will also be injured. Heading into winter, our eagles and other carrion feeders can cache in on the glut of deer carcasses. Rabbits and hares will also play more of a part as many seabirds leave the coastal breeding area and head out to open waters for winter feeding.

Nature of Scotland Awards

Great news for Mull Eagle Watch, we’ve been shortlisted for the Nature of Scotland Awards under the Innovation category. We’ll be attending the award ceremony in November with naturalist, author and TV presenter, Chris Packham hosting – very exciting!
