Islay Natural History Trust Talk & News

Next Talk
Our next talk will be this Wednesday 15th May at 7.30pm, Louise Muir from Jura will be telling us all about 'The Wild Side of Jura' where a recent application for a fish farm has sparked greater appreciation of the wild nature of Jura, locally and far and wide.  Louise will discuss:
  • The Wild Side of Jura - its natural and cultural heritage and a global community in support of its wilderness
  • The fish farming proposal  - an unsustainable model for aquaculture in Scotland
  • Impacts a fish farm would have to the natural heritage of Jura and its surrounding seas
  • Alternative approaches



New Renewable-energy Heating System
Islay Natural History Trust are working with Islay Energy Trust to look at ways we can improve our heating system in the visitors centre, whilst minimising our impact on the planet.  GeoAtlantic Project Officer, Kirsten Gow, has been working with us to calculate the heat requirements for the building, and look at whether ground or water source heat pumps can provide what we need to make the building the warm, welcoming space we would like it to be.

Heat pumps work by collecting low-level heat from the air, ground or water and compressing this into useable heat which can provide heat and hot water. The systems use up to 75% less electricity than some other heating systems, meaning that they can help reduce our carbon footprint and keep our bills low.  There are several ground source heat pumps already in operation on the island at the moment – including the one at Islay Hotel in Port Ellen which provides all the heating and hot water then need for their guests.

We are still in planning stages with this at the moment, but hope that we might be able to go ahead with upgrading our heating system later on this year.  Watch this space for more information as the project progresses.

The Islay Nature Centre

After a slow start to the start of the season due to difficulty in finding staff to operate the centre we are pushing forward, and we are now open 5 days a week 10am to 4pm weekdays.

We have lots of new developments planned now that the youth hostel (Hostelling Scotland) have now offered us a 9 year lease. In conjuction with the new heating project we are putting together proposals for insulated the building and getting better access to the terrace and beach. We are revamping the displays but all this will take some time with major works anticipated next winter.

In the meantime the tanks have been filled (using our new pump) and are being populated thanks to the efforts of Steve Wrightson.  A new sea tank will hopefully be on its way later this month to replace the big tank - which will now be used for amphibians. We will be re-organising the structure of some of the displays - aiming to 'open-out' the main display room - with a work party on Saturday 1st June, if anyone is interested in coming along and helping please email and let us know.

We now have 'self-service' tea and coffee facilities for visitors - and are looking to source some soft chairs/sofas for visitors (and members!) to relax in/on whilst enjoying their visit. Please come along and see whats happening!

We have a development officer (Emma Baker), part time to help in organising new displays and encourage greater footfall into the centre.  Our development will involve some rearranging and redesigning of the displays, teaming up with other local groups and businesses to improve the look and wildlife knowledge provided.  Port Ellen Primary School will use their newfound understanding of the marine plastic problem to provide a display and Bruichladdich Distillery are providing skills and resources to help too.

The Trust has secured two survey contracts, one for Marsh Fritillary butterflies and another for upland breeding birds on SAC sites on the Rhinns of Islay through the CANN group which is targeting upland restoration of peatland sites. This will provide income as well as the opportunity for local people to train in environmental survey skills.  I will be holding a meeting for anyone interested in taking part in this work and joining the survey team, on Thursday 16th May 7pm, the day after our next talk.

Following a very successful couple of years undertaking the roadside verges project where we actively went out and gathered wildlife records (10,458 flowering plant and pollinator records for 86km2) we have a renewed desire to improve our reach, improve our data gathering and promote our charitable remit, so our Sunday nature walks this year will aim more on citizen science, teaching and promoting interest in learning skills in all manner of wildlife and geological identification to local people and visitors.  I will be drawing together a draft plan for the Sunday walks over the coming weeks, depending on the local or visiting knowledge base, if you have skills in nature ID, the more obscure the better please get in touch and let me know and we can perhaps organise to visit sites and bioblitz areas for wildlife records.

We are aiming on developing and nurturing an informal local group who can share their knowledge, get together and chat over their wildlife experiences each month I have had recent discussions with Plantlife, Butterfly Conservation, Bumblebee Conservation, Bat groups and the Whale and Dolphin Trust, (who are launching a whale trail around the islands) organisations which we may be able to tap into knowledge and bring experts over for training and diversifying interest and skills on the island.

Exciting times ahead, so watch this space and please do come and join in our activities and events.

September Nature rAmbles!


It's the last month coming up, before our nature centre sadly closes for another Autumn and Winter, so come along to the last of our Nature rAmble walks for the month of September. We are starting out with a wander around the shoreline of Ardnave, to observe the birds and other wildlife in the area. We will also be adding back in a walk through Bridgend woodland to have a talk about the mythology and folklore of woodland trees, plants and other wildlife, which was unfortunately canceled in August due to poor weather conditions, however we have luckily picked this walk back up for September! We Will finish off with a walk along Sanaigmore bay for some seashore foraging and the possibility of some cake in the Outback Arts Gallery. Sanaigmore was one of the first walks carried out way back in June...I wonder how much it's changed over the season! Our walks start at 2pm on a Sunday and usually last between 1.5 and 2 hours. All are welcome!

A migrant moth - Convolvulus Hawk-moth

Following the migrant butterfly from the USA comes a Convolvulus Hawk-moth from the south which I caught in my moth trap last night. This is a rather worn female specimen and only the fourth I know about for Islay, past records being in c.1950, 1989 and 2015. Similar to the Red Admiral and Painted Lady butterflies, this moth lives in North Africa and, early every spring, migrates across the Mediterranean into France and Spain where it breeds, with the offspring moving further north and, more or less annually, reaching southern England, while in some years, perhaps helped by southerly winds, some reach Scotland, even as far north as Shetland. They are large moths with a wingspan up to 100 mm and length of about 55–60 mm. The male is more boldly marked with black streaks and bands.

Migratory Monarch Butterfly Blown Off Course!


Islay has been gifted with a lucky sighting this weekend by Jane Taylor, who spotted this Monarch butterfly (Danaus plexippus) near Bridgend! This exquisite pollinator is a migrant, most likely arriving from either North America, Western North America, Southern Canada, Florida or Mexico and will travel thousands of miles on migration. When migrating south along the east coast of the USA, they can get picked up by westerly winds and blown across the Atlantic, just as happens with several species of birds.

This butterfly is unmistakable by its size compared with any British butterfly, with a wingspan of 3.5–4 inches (8.9–10.2 cm) and by its orange upper-wings, with multiple black veins and margins, being narrower and lighter in the males. There are a series of white spots near the wing tips and wing borders. It can also have orange spots at the tips of the forewings. The underside is similar but with a yellow-brown colour on the forewings and hindwings instead of orange.The white spots also appear to be larger in size. The Monarch will alter its aesthetic before and after migration, starting off as a brighter red with longer and narrower wings, then fading and shortening towards the later migration stage. The male is often slightly larger than the female and will have either a black patch or dot on the androconial scales of the hindwings. The females have thicker wings than the males to compensate for their smaller body size and to help reduce energy loss during flight.

If the Monarch butterfly is ever seen within the UK, like Jane has seen near Bridgend, they are usually accidental migrants, not turning up every year, and so are a treat to spot! This species is found on agricultural land, pasture land, prairies, gardens, woodlands and roadsides. Monarchs use mountain forests in Mexico to migrate to for their winter habitat. The main threat to them lies in the forest also being a natural asset and resource for human use. Climate change will also affect their migration flight such as wintering grounds becoming colder and summer breeding grounds becoming warmer, thus shifting the migratory pattern.

The Monarch butterfly is unfortunately decreasing in population due to the above threats and the use of herbicides and pesticides on land. The U.S. Fish and Wildlife Service is currently undergoing research to decide by 2019, if the species should be protected under the Endangered Species Act. In Ontario, Canada, the species is listed under Species of Special Concern; however, in 2016 it was proposed to move the species into the endangered list for Canada, due to the drop in population.

There are, however, efforts being made to conserve this species and its habitat. The restoration of appropriate habitat in woodland glades for increased herbaceous ground cover for host and nectar plants, providing monarch-friendly seed mixes such as milkweed and controlling the timing of habitat management such as mowing to reduce compromising the species. These are only a few efforts among many more strategies. Fingers crossed for their conservation status change and an increase in population trend!

Although not common to find in the UK, keep your eyes pealed for any unfortunate Monarchs blown off the migratory path! In years when one is seen, it is usual for several others to turn up in different places.

Cuvier's Beaked Whale

For only the third time that has been recorded, a Cuvier's Beaked Whale has washed up on Islay's shores. A very dead specimen turned up a few days ago on the Big Strand. The previous ones were in 2000 and 2008. And exactly the same as in 2008, other specimens have turned up at the same time in the Outer Hebrides. This is an uncommon species in British waters, very rarely seen alive, though strandings occur more frequently, if not annually. This is a deepwater species which prefers warm waters, so is seen more regularly in the Mediterranean and around the Canaries. It has been suggested that the species is particularly adversely affected by the sonar used by submarines and other naval vessels, perhaps to the extent of causing the strandings.
I've taken specimens of the skin, blubber and muscle which have been sent away for analysis by the Scottish Strandings team in Inverness. They will be checked for pollutants as well as having the DNA analysed to see if related whales have also been stranded.

A Glorious Day At The Islay Show!


The Islay Show was a great success yesterday, with the sun shining and the rain that was promised...absent! We had a great turnout at our Islay Natural History Trust stand. The activity in and around the stand, shop display and activities was buzzing with life.

Our games consisted of 'The Great Bird Race', featuring a Chough, Corncrake, Lapwing and Mallard, of which were selected by their players and raced against each other for the prize of a INHT lanyard. Our other game sent the children fishing in 'Fishing Jackpot' and they had to pick an animal to help (Gannet, Otter, Grey heron or Puffin) catch a pair of fish with matching numbers. There was the opportunity to win sweets and more depending on how many matching numbers were found...It's safe to say that our sweet jar was very much empty by the end of the day! Although these attractions were very popular with the children passing by, there were also a few keen adults who could not resist!

One of the more popular attractions of our stand this year with both adults and children was our 'Find the Islay Otter', of which the public had to guess which grid square on the Islay map, the otter may have been hiding. Each square had a number and at the end of the day, all of the chosen numbers were raffled and a winner was chosen! Our prizes consisted of a Kilchoman Machair bay and Sanaig Whiskey gift set (for the adults) and one of our cuddly toy otters! Well done to Eva who successfully found the otter and has won our prizes!...and a thank you to David Webster and Bernard Hannett for helping out for the day and Bernard for being a brilliant mascot for showing off our wonderful prizes.

The day was glorious and a big thank you to anyone who came along to visit our stand and who took part in any of our activities! Make sure to pop along to our centre in Port Charlotte, where we are open from Monday to Friday from 10am to 4pm. All are welcome!

A weekend of pollinators.


The weather although a bit cloudy has been fair and warm which has been great for pollinators.  I spent a nice afternoon on Saturday walking the road from Sanagimore to Kindrochid finishing off a pollinator survey.  Despite the verges having been cut earlier in July the margins beyond the cut were still prolific in flowers knapweed, the bramble bushes and meadowsweet providing the main focus to bumblebees and butterflies.  Near the Islay Development apiary site the honeybees have been mainly foraging on bramble and the meadowsweet too, the latter made obvious with a build up of green pollen in the bee's pollen sacks.  Observation indicated bees were focusing either one or the other, not mixing visits between flowers.

Tachina grossa

A large fly called Tachina grossa  has been a frequent sight these past few weeks, black and the size of a medium sized bumblebee, soldier beetle, along with other flies it was favouring the umbelifers, in this case Hogweed.

Soldier Beetle












At the Islay Development apiary site there is a patch of hedge woundwort in front of the hives, although some of the honeybees can be seen visiting the flowers the main interest is from the bumblebees (the longer tongue of the bumbles able to access better the tubular funnel of the flower), primarily Garden bumblebee and Carder bees.  I counted c. 35 in total at one tally.

Sunday's Killinallan dune walk was not attended by anyone this week, but I walked through the dunes anyway to see what was out and about.  There were plenty of butterflies: Common Blue, Meadow Brown, Small Tortoiseshell, Peacock, Grayling, Small Heath, and Dark Green Fritillary.  Flowers now showing were Devil's Bit Scabious, Harebell and Autumn Gentian with many of those out a month ago setting seed and on the wane.

Dark Green Fritillary

My end goal was to reach the beach at the point, below me down the dune was a fantastic patch of Sea Rocket in full bloom and on closer inspection was a very busy place, 4-5+ white-tailed Bumblebees on each bush and then lots of smaller bees which when I got in close up all turned out to be the small mining bee Colletes floralis, hundreds of them!  I spent ages with camera aiming for the perfect shot, and scanned up and down all the clumps to see what other bees there were.  A red tailed individual caught my eye, bees with red tails are not at all common here, I never did get a great shot of it but my first Mountain Bumblebee, there appeared to be only the one amongst the....195 white-tailed bumblebees, yes I counted them, give or take 5 or 10?  I got very excited by a very yellow looking bee, so took lots of pics, for ID later, it has turned out to be a male white-tailed bumblebee, in all the surveys I have been doing this is the first one I have knowingly seen, quite distinctive and different from the female queen and workers.  I so wanted it to be a great yellow bumblebee, but alas no big fanfare, that would be a first for Islay!

Bowmore Seashore Safari


A nice session of fishing for sea creatures near Bowmore Battery was rewarded with lots of little fishes and crabs.  The children netted opossum shrimps, brown shrimp, a lovely little flat fish, a very small pipe fish, lots of fry, hermit crab and finally a big shore crab was found lurking under the seaweed.  They learned about crabs shedding their old coat to make a new one and how anemones catch and eat little fishes!
