Aigas Ranger Training: Part 3

9 March, 2018. Posted by Aigas Field Centre

Day 1 We started the week with an early morning run to the Inverness shore looking for otters. To our delight we spotted a mother and her cub. Following that great success we headed to the east coast to explore for wildlife on sea lochs, freshwater lochs and sand dune habitats. We had shows from an array of wading birds, seals (common/harbour and grey/atlantic), kestrel, sparrowhawk and, best of all, a peregrine falcon hunting wood pigeons! Day 2 Dan Puplett, a freelance woodland ecologist, spent the day with us teaching us about – you guessed it – woodland ecology. We visited an ancient remnant of Caledonian pine that is found in one of our local glens to identify trees in their winter ‘coat’. Looking at the trees

Treecreepers at Aigas

27 February, 2018. Posted by Aigas Field Centre

It has been a cold winter in the central Highlands and we are accustomed to wearing our full length pyjamas to bed along with the occasional hot water bottle to keep us warm at night. Our native wildlife however have a range of slightly different techniques to ward of the chill of a winter’s night. During the day it is clear to see the signs of overnight occupants in the crevices of the giant sequoias on site. A small amount of white guano dotted underneath the rounded nook in the spongy trees bark gives this away. The impressions (larger than golf balls, smaller than tennis balls) speckle the trees and appear to have been excavated by something. By 9:30 on a cloudy Tuesday evening, darkness had taken

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

The Big Garden Bird Watch

30 January, 2018. Posted by Aigas Field Centre

This weekend RSPB held their annual Big Garden Birdwatch. A nationwide wildlife (primarily bird) survey that is participated by half a million people. This year we got involved. Undeterred by the rain, our ranger team spread out across the estate, sitting at some of our many feeding stations to carry out the count. In the one hour, we recorded 17 different bird species. This included the tits – blue (Cyanistes caeruleus), great (Parus major), coal (Periparus ater) and crested (Lophophanes cristatus); dunnock (Prunella modularis), chaffinch (Fringilla coelebs), siskin (Spinus spinus), yellowhammer (Emberiza citrinella), robin (Erithacus rubecula), treecreeper (Certhia familiaris), house sparrow (Passer domesticus), carrion crow (Corvus corone), raven (Corvus corax), blackbird (Turdus merula), great spotted woodpecker (Dendrocopos major), collared dove (Streptopelia decaocto) and red kite (Milvus milvus).

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

Toothed jaws on the west end

14 December, 2017. Posted by Aigas Field Centre

Back in July the Aigas Loch was alive with fast, beautiful, prehistoric predators of the air. Their ancestors with 70cm wingspans were the largest creatures in the air 300 million years ago. Dragonflies are a pleasure to watch wherever you are in the world. Some people dub them the new birds with their rise in popularity amongst twitchers. Dragonflies don’t call or sing to give away their presence however their 2 sets wings beat at around 30 times a second often making an audible hum which draws your attention. [caption id="attachment_1629" align="aligncenter" width="551"] Spotted chaser[/caption] Our world is home to 5,900 species of dragonfly, we have 45 of them living in Great Britain & Ireland, 11 of which feed and breed on the Aigas estate.

Foxes at Dawn

4 December, 2017. Posted by Aigas Field Centre

A frozen loch gleams icily in the last hour of night.  An eerie stillness settles around us.  No birds are stirring yet; deer are still out on the river fields, yet to slip back into the woods as winter daylight slowly spills in from the cloudless east.  Whisps of ghostly white mist hang over the valley and somewhere far upstream we can hear the bugling of the twelve whooper swans that have winged in from the high Arctic to winter on our river. We had dumped a road-kill roe deer carcass out on the moor with a stealthcam in place to see who and what would exploit it.  The first and obvious images were fox.  A solitary fox tugging at the rib cage and hauling it off

A busy night at the Quarry Hide

28 November, 2017. Posted by Aigas Field Centre

Having been at Aigas for almost a month and not seeing a badger, I decided to head to the Quarry Hide on a night off and wait for as long as it took in the hopes of seeing one of Britain’s largest land carnivores. At 7pm, after baiting the logs at the hide with peanuts and peanut butter, we headed inside to wait. Not long after we had arrived, the trees to the left of the hide rustled and we saw a shape moving around. It was a barn owl which flew around for a bit before perching on a tree trunk directly in front of us. It stayed there for a few minutes, giving us a good show before flying off into the darkness. Only a
