Mull Eagles

Follows the fortunes of Mull's white-tailed eagles and its other fascinating wildlife
  • Flying High

    The white-tailed eagle chick from the Glen Seilisdeir nest fledged safely back at the beginning of August and, after over a week spending much of its time on the ground in the clearing below the nest, is now to be seen soaring high above Tiroran Forest and the adjacent moorland.

    Last week the visitors to each trip of Mull Eagle Watch had probably the most spectacular views of the year. We are now walking around 1 mile along the forest track to an area of most spectacular views over Kilfinichen Bay, out over Loch Scridain and up to Ben More. This is the place where the eagles are currently most often to be seen, perched on some of their favourite lookout spots, or soaring over the tops of the huge spruce, larch and pine trees. We are also regularly seeing a sub-adult white-tailed eagle, probably a chick raised by this pair several years ago and on one day this week we watched as this bird performed an aerial ballet with this years juvenile: a wheeling and tumbling duet, with one of the eagles flipping over and showing its talons, seemingly part in play, but also with the serious edge of practising for future territorial disputes and mating rituals.

    Yesterday, the visiting RSPB Aberdeen Local Group watched as the eagles soared over the adjacent moorland, being mobbed by our local pair of buzzards. A large flock of hooded crows were also in attendance and three ring-tailed harriers, probably the mother and two juveniles, swooped and dived, mobbing both the crows and the eagles. In the afternoon, another group of visitors were even more privileged to have close views of Iona and the juvenile flying low overhead, heading off across the Glen to alight on the moorland. Iona had obviously dropped food for the youngster, because as soon as it landed, it mantled its wings, shielding the prey before starting to rip it up with its big powerful beak.

    The chick will spend a few more weeks at least in its parent’s territory, mastering flight and hunting, but still being supported by Iona and Fingal. Then it will be off, ranging far and wide in its 4 or 5 year journey to maturity, finding a mate and establishing its own territory. Provided its survives the first year, often the most critical time of its life, it may return with its mate to establish a territory close to the parents range.

    Mull Eagle Watch walks should be continuing until the end of September (2 hours starting at 10am and 1pm most weekdays). Booking is essential on 01689 812 556.

  • MAGICAL EXPERIENCE

    For 5 months this year I have been leading trips to watch the pair of white-tailed eagles that are nesting in Tiroran Forest, Glen Seilisdeir on the Isle of Mull. There have been some memorable moments during that time: our two adults mating in a tree after the female had laid her first egg, the first sight of the downy white head of the chick after it had hatched, food being brought to the chick on the nest, aerial battles between our white-tailed eagle adults and intruding sub-adult golden eagles, and the first hesitant flight of the juvenile. But this week the most magical experience of my year occurred, with a close fly past of this year’s juvenile.

    I was standing by the telescopes, outside the hide, searching the nest area for any signs of the birds in the last 10 minutes before I was due to collect the visitors for our first trip of the day. Suddenly, a huge dark bird appeared in the sky and passed directly overhead about 20 feet above the ground, almost blocking out the sun. I could see every detail of its plumage: the enormous ‘fingers’ of the primary feathers at the end of the rectangular wings, one of which had slight damage along its leading edge, the distinctive wedge shape of the pale tail feathers with their darker brown margins, and the ruffling of the soft feathers on the head and breast. I could see its eyes clearly, looking directly at me as I stood, rooted to the spot. No time to rush and get my camera. Probably just as well as I wouldn’t have been able to concentrate on the bird and appreciate the majesty and close proximity of this youngster that has been the focus of our attention and concern this year at Mull Eagle Watch.

    I would like to think it was looking at me with appreciation for protecting it this year, but I am certain it was just interested in another new sight, another new experience at the beginning of the learning process, of the development to an adult, of the search for a mate and territory, and of what we hope will be a long and productive life, helping to repopulate Scotland and beyond, getting this wonderful bird of prey back where it belongs.

  • FLEDGED!

    The white-tailed eagle chick from the nest at Mull Eagle Watch, Glen Seilisdeir has fledged successfully. After several days of sitting on branches around the nest, when its wing flapping and teetering on the point of flying had drawn ‘oohs’ and ‘aahs’ from the visitors watching through telescopes and binoculars, it finally flew just 50 metres across the clearing into the top of another of the big conifers in the forestry plantation of Tiroran Forest. At first it looked as though it would not be able to steady itself, but gradually it scrambled toward the trunk of the tree, grasping the flimsy branch with its huge, bright yellow feet, eventually appearing to lean against the trunk for support. You could hear the intake of breath from the relieved watchers.

    Plaintive calls from the chick echoed across the glen, part exultation at being free from the nest at last, part calling to its parents for food: for days both Iona and Fingal had been tempting their offspring away from the nest by bringing in less and less prey. Iona, who had been perched in a conifer above the nest, then took off and glided to where the youngster sat, alighting gently on a more sturdy branch just below. She seemed to be willing the chick to fly again and begin its journey into adulthood: the young bird will probably spend a couple of months shadowing its parents as it learns the tricks of the trade of flying and hunting - of being a majestic white-tailed eagle, the fourth largest eagle in the World.

    Both birds sat there in silent harmony for 15 minutes, until Iona decided it was time for her to head off to Loch Scridain to search for another greylag goose gosling, the main prey item the eagles having been catching for the last few weeks. The chick watched intently as she flapped across the clearing and soared off over the woodland, her pale head plumage and white tail gleaming, catching the sun as she turned this way and that searching for a thermal to take her effortlessly up into the blue sky. The chick leaned forward, almost toppling, and then after a few moments launched itself from the branch, seemingly heading back to the nest, but falling short and landing awkwardly in the top of a larch just below the nest tree. Using its wings in the mantling style, it steadied itself on the foliage and finally found a good perch, remaining there for the rest of the afternoon.

    It is a long hazardous journey for the white-tailed eagle chicks. Ours was laid in the egg back near the end of March, eventually hatching 38 days later. During that time both Iona and Fingal had taken turns at the incubation, never leaving the egg uncovered on the cold and wet days, and certainly never leaving the nest unguarded: attention from unwanted guests this year has included ravens, hooded crows and even the non-breeding pair of golden eagles that have been harassing our white-tailed eagle pair all year (we even had a nearby sighting of a pine marten, a recent coloniser of Mull, and a species notorious for stealing eagle eggs and young chicks from nests). Human activity too nearly caused problems for our pair this year, with some wildlife watchers approaching too closely and paying far too much attention to the nesting and roosting eagles.

    Once hatched, the chick was shown constant attention by its parents for the first ten days, brooding it for much of the time, but also taking great care in feeding small pieces of flesh from the many fish and other prey items that Fingal was bringing to the nest. The small white ball of down that was the freshly emerged chick developed quickly, soon beginning to grow the dark brown flight feathers that distinguish the juvenile white-tailed eagles from the mature birds.

    At the end of the second week in June, the chick was ringed: climbers scale the nest tree and check the health of the bird as well as fitting the two leg rings that are used to distinguish this individual in the future. From then on it was a question of the chick eating as much as possible, growing its full flight feathers, and exercising its huge 8ft wings to develop the flight muscles that are required to lift this huge bird into the sky. Wing flapping, ‘trampolining’ and ‘branching out’ were then the order of the days of the last few weeks on the nest.

    Last weekend I watched our chick soaring expertly over the forest and moorland, but in the last few days, high winds and rain have meant that the chick has been unable to fly very far. I hope that some fine weather this week will enable the chick to really commence on its journey to adulthood, finally heading off on its four or five years of travels, maturing and searching for a mate: another small step in the repopulation of Britain by this extraordinary bird.
