A flutter of excitement

A brief flurry of excitement the other week. Returning from a butterfly survey in Baluain Wood, above the castle a flighty fritillary butterfly was sighted. After a short but mad dash, waving the butterfly net wildly about to apprehend the fast flying and elusive insect, it was caught. A few tense moments as the butterfly was carefully transferred from net to viewing pot and allowed to settle so its identity could be confirmed. Then a sudden release of baited breath and mild sting of disappointment - this wasn't the pearl bordered fritillary (Boloria euphrosyne) that we had been hoping to find but its close cousin, a small pearl-bordered Fritillary Boloria selene).

What is it? PBF or 'just' small PBF?!
Strange to think that we put such value on rarity that we should feel any sort of disappointment at seeing such a lovely butterfly up close. For the pearl-bordered fritillary is more scarce than the small pearl-bordered but the populations of both are threatened in the UK, so to come across either and capture a photograph is something of a treasure. The excitement of discovery is heightened too by the close similarity of the two species - often easily confused - the most obvious difference being the number of white 'panels' on the underside of the wings, requiring a close look for confirmation. If any further confusion were needed over the matter, the 'flight periods' of many butterfly species (the times when they are on the wing) are out of sync with the usual timings due to the long staying winter weather earlier in the year and subsequent rapid advance of summer. In the end it all adds to the excitment.

There are more ways to distinguish the two than by the under-wing patterns alone.For a more detailed comparison of the two Boloria click here or check out the Butterfly Conservation website (follow the species links above).

Where Have All the Butterflies Gone?

Beautiful hot, sunny weather has come to Highland Perthshire. Summer has arrived at last. The sunny weather is perfect for butterflies, but sadly there are hardly any to be seen. The ranger service surveys 2 butterfly transects every week, and the lack of butterflies has been very evident. The flowers are abundant with nectar for the butterflies to feed on, and the weather is certainly warm anough for them to be active.
Ready for a butterfly transect.
The reason that the butterflies are not around goes back to the poor summers of the last 2 years here. Poor weather gave them little opportunity to be active to feed and breed. It may take some time for the populations to build up again locally. However, ringlets are just appearing and will soon be followed by Scotch Argus. These butterflies can be active in poorer weather and so were less affected by the conditions of the last 2 years. So we should see some more activity if the sun stays shining!

It's also better news locally with the moths, which are certainly enjoying the warm nights and are making up for the lack of butterflies to some degree. Because they are mostly nocturnal, they don't need sun and warmth to the same degree as butterflies and so are less affected by poor conditions.  This is good news because many bird species are dependent on moth caterpillars to feed their chicks, and moths also pollinate many plants.

Wild Scotland: spaces for nature

A brilliant short video produced by 2020 Vision that we came across and couldn't resist sharing with you. The video encourages and explores the idea that nature needs our help and we need it. The video gives a special mention to several places and projects going on across Scotland and in the Cairngorms National Park too. Make your own wee space for nature - sit back, relax and enjoy it!

New Atholl Walking Trails

The ranger service has been hard at work installing new set of waymarked trails around Blair Atholl and the surrounding area. The way markers are now all in place for visitors and locals alike to explore the trails but the work wouldn't have been possible without the hard work of volunteers and input from the Cairngorms National Park Authority and local Tourism Association.



Three of the trails start from the Blair Atholl Information Centre, located on the main road beside the River Tilt, and two more begin from Struan, to the north. A sixth trail uses the existing trails around the Falls of Bruar, starting from the House of Bruar.

Copies of the accompanying Atholl Trails booklet, guiding you around the walks, are available in the Blair Atholl Information CentreYou can view a printable version of the Atholl Trails booklet, guiding you around the new walks printed copies are available in the Blair Atholl Information Centre. You can also view a printable version of our own Waymarked Trails from Blair Atholl online.

A Day for Dwarf Shrubs

The rhododendron is in full flower in the Castle grounds and looking quite magnificent. However, the common rhododendron (Rhododendron ponticum) is not always so welcome out in the wider countryside where it can spread through woodland swamping other vegeatation completely until there is nothing left but the rhododendron. It looks good at this time of the year, but it's not a good wildlife habitat at all.


But there are other native shrubs that are flowering just now. They are a lot smaller than rhododendron, but they don't take over, and provide much more for our birds and animals.

Here are the flowers of cowberry, an evergreen shrub of woodland and moorland, and blaeberry (or bilberry in England), which is deciduous. Both of these flowers will eventually turn to fruit. We know and love the blaeberry, but so do many other creatures - lots of birds and some mammals including pine martens and badgers. The cowberry has a red berry which is not so tasty to us (though not poisonous), but still important for other creatures.

 In addition the bushes provide food for many insects, which then provide food for birds, especially chicks which need protein to develop. The capercaillie feeds its chicks on caterpillars from blaeberry bushes
These shrubs also provide great shelter, particularly for ground-nesting birds.

Bambi and Other Babies


Spring has definitely arrived at last and the grounds of Blair Castle are teeming with new life. An oystercatcher has laid eggs in the car park (don't worry, we've roped it off so they don't get squashed!) and another oystercatcher has chicks running aound near hercules Garden. The resident swans in the garden are also busy on their nest, and are pretty unwelcoming if you get too close.

You need to look carefully! Not the best shot but after this it went inside the tree fence and was even harder to see!
 
Two red deer calves have also just been born in the deer park. They look gorgeous with their spotty coats which are for camouflage. The mother also cleans their rear end assiduously so that they don't give off any scent to attract predators when they are left alone on the hill. She leaves her calf while she feeds and returns to it later .Calves usually appear earlier in the park than in the wild because the deer here have an easier life and are better fed. Wild calves are usually born in June though it may be a little later this year. If you visit and notice that the magnificent stag is missing, don't worry. He has gone to a new home and will be replaced with a different stag so that there is some fresh blood / genes - we don't want the deer to get too in-bred.
