The dolphin, the dipper, and the ‘dunno’

3 July, 2018. Posted by Aigas Field Centre

Last month our Walking and Wildlife group had excellent views of bottlenose dolphins (Tursiops truncatus) surfacing and later an adult dipper (Cinclus cinclus) which was teaching its fledgling to swim along a stream. Towards the end of the day, a member of the group spotted this unusual looking bird which both surprised and confused our rangers. After some investigation, we confirm this is a black bird (Turdus merula) with a plumage abnormality.  In addition to various pigment abnormalities, plumage abnormalities can include issues with feather growth or loss. A common misconception is that pigment abnormality is albinism or leucism, however the bird is capable of producing dark feathers therefore cannot be classified as a true albino. This could be detrimental to the individual’s survival as it is

Naturedays on the Isle of Skye

28 May, 2018. Posted by Aigas Field Centre

Over winter, the Naturedays team travelled to many primary schools and nurseries around the Highlands to deliver an outreach programme on how animals survive the harsh winter months. As we entered spring, the outreach changed from this theme to one on energy flow. The education team recently took a trip to the Isle of Skye as the first schools to receive this new programme were two primary schools on the island. Skye is the most easily accessible island in the Inner Hebrides since the completion of the Skye Bridge, a free road bridge from the mainland. The first school visited enjoyed the presence of the whole Naturedays team for one session, before we split and two of us departed for the second school. A variety of topics

Nature Photography at Aigas with Laurie Campbell

28 May, 2018. Posted by Aigas Field Centre

Laurie Campbell is one of Scotland’s leading nature photographers. His knowledge of the natural world has allowed him to photograph Scotland’s most iconic species, producing beautiful results. Here at Aigas, we’re lucky enough to have him lead programmes throughout the year. He runs a photography workshop and a masterclass for more experienced photographers. I am definitely not a photographer. My experience consists of pointing and shooting a hybrid camera with blurry results. On past trips out with Laurie I’ve felt a little intimidated by the guests’ flashy cameras and the photography jargon (I still do not know what ISO stands for). However, last week I took my camera with me for a day in Glen Starthfarrar with Laurie and his group, and I’m so glad I did.

Discarded antlers all around us

9 May, 2018. Posted by Aigas Field Centre

It is the time of year where we find shed antlers around Aigas. The Red Deer (Cervus elaphus) have finished their rut, and the stags are now shedding their antlers in preparation for this year’s rut. The smaller Roe Deer (Capreolus capreolus) will soon enter their breeding season, we have already spotted some young bucks in hard antler. Antler physiology Antlers function as an object for sexual attraction, the quality of the antler can determine how successful the male will be during the breeding season. Male deer use these antlers to lock with other males and wrestle for mating privileges, they can be used as weapons, but their primary purpose is ornamentation for sexual selection. Some species such as Chinese Water Deer (Hydropotes inermis) possess tusks which

The Rewards of Walking in the Hills

19 April, 2018. Posted by Aigas Field Centre

Back in February, Pete and I decided to hit the hills of Glen Affric armed with warm boots, plenty of layers and ice axes for a day of winter walking. With the Highlands still firmly in the grip of winter’s freezing fingers, we had a limited number of daylight hours to play with. With our alarms set for 4:30am, we aimed to be walking by sunrise. Being woken up at such an early hour always feels a little painful, but once you are outside the sacrifice pays off. I find being surrounded by nature at this time a moving experience, hearing the dark morning silence broken by the song of a robin or the movement of a roe deer in the bushes and seeing the first rays

Aigas Ranger Training: Part 2

23 February, 2018. Posted by Aigas Field Centre

Over the last week we have done a lot of walking, wandering through local straths, glens, farms, forests and along the shore discovering Scotland’s spectacular array of wildlife and delving into its great history. Day 1 On Monday we explored a beautiful route through Forestry commission woodland, past a loch, landing us in the wonderful Victorian village of Strathpeffer. Jonathan Willet challenged us to see (or hear) ten species of birds on the short walk and in no time at all we had coal, blue and great tits ticked off, soon followed by chaffinch, treecreeper, robin and wren. Towards the end, and to our delight, we heard calling crossbills, croaking crows, the drumming of a greater spotted woodpecker and a large flock of siskins fluttering between the

Aigas Ranger Training: Part 1

21 February, 2018. Posted by Aigas Field Centre

For the next 8 weeks the Aigas rangers will follow a comprehensive research programme, taking an in depth look at the geology, history, mega and micro fauna and flora of the Scottish Highlands. Day 1 Ben, Aigas' Staff Naturalist, started the day with an introductory talk on the Eurasian beaver, Castor fiber, with focus on our collection here at Aigas, updating us on our beavers movements and behaviour throughout the winter months. Following this he took us on an interpretive walk around the loch giving rangers the chance to identify signs of animal activity and learn about the history behind Loch Cuil na Caillach ('the nook of the wailing woman', aka the Aigas Loch). Along the way we saw crested tits, red squirrels and a jay. Day 2

Amazing Badger Behaviour Caught on Video

2 February, 2018. Posted by Aigas Field Centre

One of our regular guests at Aigas, Wendy, has recently sent us some stealth camera footage from a couple of her visits here last season, which included quite a few clips of badgers around the estate. Badgers (Meles meles) are generally solitary foragers and use their well developed sense of smell to find food. This clip shows an example of a badger searching a feeding area, maybe for earthworms or insects which are two of their main sources of food.   Badgers also have long claws on their fore paws which are useful for digging setts and foraging. Here we can see one using its claws to easily reach the food it has found. Sometimes badgers’ foraging grounds overlap which can cause disputes over food. An example

Three mammals, three facts

25 January, 2018. Posted by Aigas Field Centre

The pine marten, otter and red squirrel are three of the UK's most iconic mammal species, and at Aigas we are lucky enough to see them all regularly. Here are three things to know about our amazing fauna friends. Red squirrel (Sciurus vulgaris) Their fur colour can range from a reddish brown to a deep brown. They undergo moults in spring and autumn, the latter producing a darker fur. This darker variation can be seen in the video below -  but be vigilant as the squirrel is quick to move! Some of you may have seen deer antlers hung up in various places and wondered why. Red squirrels gnaw on them to get calcium as their diet does not provide them with sufficient amounts. Squirrel pelt was

Living alongside Chimpanzees in Uganda

24 January, 2018. Posted by Aigas Field Centre

I arrived in Hoima, Uganda, on Monday 15th, and since then it has been an absolute whirlwind of experiences, every one of them incredible. I spent a night in the Itahyo Forest where the Chimp Trust works with the community to manage the forest effectively for chimps and biodiversity. The forest is beautiful and peaceful, with a tree nursery inside being managed by the forester. The dedication of this man to the forest he has managed for decades is inspiring. During the evening a group of wild, unhabituated chimps decided to nest about 100m away from the lodge, meaning I was able to watch them the next morning for over an hour - another bucket list moment of this trip. I was not alone in watching these
