Glad to be back!

mull sea eaglesAfter what seems like a very long (and extremely wet) winter, I'm finally back watching eagles and sharing the experience with our visitors at our wonderful new location.


Our resident pair of Sea Eagles have been named Iona and Fingal, and are proving just as devoted parents as Skye and Frisa did at Loch Frisa. Iona (the female), previously known as Green T because of her wing tag which she lost this winter, was reared on the Isle of Skye by her parents who were from the first release of Norwegian Sea Eagles on the Isle of Rum. After fledging in 1998, Iona was first seen on Mull in 2001. Fingal (the male) was part of a second release scheme and was brought over from Norway in 1997 with 9 other chicks. All 10 were released on Wester Ross. Fingal was originally known as Blue 6, but lost his tags in 2006. Following his early visits to Mull. he paired up with Iona in 2002. After a couple of false starts the pair finally fledged one chick in 2005, and have successfully fledged five chicks in total.


Our new set-up at Glen Seilisdeir is very different from Loch Frisa - we still have a wooden hide where visitors can listen to our introductory talk inside (if it's raining), and pick up leaflets, booklets and make any purchases. We then drive half a mile along the track to our viewpoint car park where we all carefully close car doors and make sure no car alarms have been set, before silently walking 100m to our viewpoint - an outdoor hide just 300m from the nest! As I write the eggs are just over three weeks through incubation, so in around two weeks we should spot the first food being brought in and tiny morsels gently fed to a tiny fluffy white chick. With luck a second chick will hatch a couple of days later.


Our "rustic" hide is a clearing in the forest, expertly prepared with a thick layer of wood-chip on the ground, shielded from the eagles' view with a screen of spruce prunings and set up with spotting scopes and binoculars so that all our visitors get the best possible view of the eagles. And what views they have been getting! We watch the adult birds taking turns at incubating the eggs, carefully rearranging sticks on the nest, and preening their loose white body feathers prior to going through their full moult. Iona usually does the night shift, with Fingal coming in to relieve her in the morning and then they take turns to incubate the precious egg(s) during the day.


Recently whilst Fingal was incubating he must have become a bit "peckish" because he suddenly took off and flew towards Loch Beg. Our hearts were in our mouths as there was no sign of Iona and the eggs would chill if they were left for long. We timed his absence and after just three minutes Fingal returned with a large fish, settled himself back on the nest and proceeded to eat his catch. He must have been able to see the fish from his position on the nest, and temptation must have got the better of him!


All our visitors are thorougly enjoying the experience, especially the "wild" hide where they can really feel at one with nature.

It's great to be back!

I'm delighted to say I'm back after six months away from Loch Frisa - although I have to say that I couldn't stay away completely and had to pop back from time to time to see how Skye and Frisa were doing!

The hide is now open again all week, and this year our White-tailed Sea Eagles have chosen one of their old nests. They are just over half-way through incubation, and as ever are being model parents. As one bird leaves the nest the other takes over immediately and we can often hear them call to each other when it is time for a changeover.

The weather this week has been changeable to say the least; as the clocks went forward last weekend we all thought Spring had truly sprung. How wrong we were! On Wednesday temperatures plummeted and we were treated to a day of blizzards, sleet, hail and strong winds. We had to cancel trips to the hide as the track was too slippery to drive along, but by the afternoon the snow was beginning to thaw and on Thursday the weather was improving (although still bitterly cold).

It is always a worrying time when the weather changes for the worst whilst the eagles are incubating eggs. The sitting adult needs a break from incubation from time to time, whether to go hunting or to stretch their wings and legs, but the changeover needs to be rapid to avoid the eggs chilling.

Two years ago another pair of Mull's Sea Eagles were disturbed by a photographer who stood under their nest to try to take the ultimate photograph. The female eagle was sitting on the nest at the time, on the first day of incubation. She was frightened off the nest and was away for long enough for her eggs to chill and die. Of course, she could not be sure that the eggs weren't viable, and the pair went on to incubate for over 60 days (when the normal incubation time is around 38 days). It was heartbreaking to watch them sit there day after day long after the date when their eggs should have hatched.

Fortunately our excellent "Operation Easter" Scheme (of which more later) meant that the photographer was arrested, charged with reckless disturbance, fined and had all his photographic equipment confiscated. Last year the birds built a new nest and successfully reared two healthy chicks, and they are incubating eggs again this year - not bad for a pair of birds over 30 years old. We would normally expect them to stop breeding in their early to mid twenties.

The weather today is beautiful; one of those clear, crisp days with blue skies and brilliant sunshine that make you glad to be alive. Our eagles must think so too, as at the 10 a.m. changeover Frisa (our female) stretched her wings and, after checking that Skye was safely settled on their precious eggs, flew off into the sunshine to find her breakfast.

Just to convince us that Spring really must have arrived, our Sandmartins have arrived back from Africa and are already checking out last year's nest holes in the old quarry wall at the rear of our visitors' car park by the hide. Lapwings are flying across the fields in front of the hide and our feeders are a constant hive of activity with chaffinches and siskins squabbling over the feeders and a Greater Spotted Woodpecker coming in to the peanut feeder.

At present our hide is in the same position as last year and we are not able to see the nest, although we have excellent views of the "off-duty" bird sitting in their favourite perch just opposite the hide. We can't risk moving the hide at this sensitive time whilst the birds are still incubating, but as soon as those eggs have hatched the hide will be moved into position and we are promised excellent views of the nest, chicks and adults. 2010 is destined to be an exciting year for us, for Skye and Frisa, and for our visitors. Do come to see us if you can.

Time for a bath

Today dawned warm but dull with the forecast for rain. This morning at the hide we were treated to great views of both adult Sea Eagles flying and bringing in food, and the chicks were very active on the nest. At 33 days old now they are growing fast and are now greyish brown - difficult to see against the branches in the nest until they move.

The juvenile Golden Eagle came through again - he nearly always takes a direct line over the nest and I wonder if he is looking at the store of food that our Sea Eagles have left for their chicks. Thank goodness he hasn't been tempted to go and help himself, and our adult birds don't seem to be too worried by his visits.

This afternoon the promised rain arrived. Both adult Sea Eagles were away from the nest but within minutes of the heavy rain starting both flew back in, one with food, and the chicks were fed and sheltered.

I took a group of visitors to our forward hide and we were treated to the most amazing sight. Frisa flew out of the trees and circled above the loch in front of us getting lower and lower. We all thought she was going to take a fish but no, she landed in the shallows about 150 metres away from us. First she drank, and then she bathed. Not just a quick dip, but a real dunking, shaking her wings and dipping her whole body under the water. After a while she walked out onto the shore, had a good shake and began to preen. We could all see her with the naked eye, but with binoculars and scopes the views were amazing.

Once she was happy with her appearance she took off and flew to the trees opposite us, all the time being mobbed by two Hooded Crows who actually made contact with her. One of them had the temerity to land in the tree next to her, but it soon decided she was a bit too close for comfort and disappeared.

It was certainly the closest view I've ever had of an adult sea eagle, and our visitors were speechless. After 38 days of incubating her eggs, followed by another month tending her chicks and feeding them, Frisa must have been feeling very much in need of a clean up - she really did seem to be enjoying her ablutions. Now her tail is whiter than white again!
