Kilpatrick Hills, West Dunbartonshire

Today I walked through the Kilpatrick Hills - from Little Round Top to the Test, around the Greenside Reservoir and then to the Northern side of the Cochno Reservoir. I was hoping to photograph some Small Pearl Bordered Fritillaries.

At Little Round Top I lifted some rocks, which revealed, amongst other things, a colony of Black Garden Ants (Lasius niger). I need to spend a day photographing this species in more detail, as they are extremely interesting.

In the photos below, worker ants (non-breeding females) are rushing to take the cocoons to a place of safety. Larvae of this species do not have a pupal stage but instead spin themselves silky cocoons - various stages can be seen in the photos.

This species is omnivorous and often 'milks' aphids for their honeydew. Lasius niger translates as 'Hairy black' (Lasius, from Greek lasios = hairy, and niger = black).

The fruits of the Dog Rose (rosehips) can be made into jam, syrup or tea, and are rich in vitamins A,C and E (as well as flavonoids).

The meadow around Little Round Top was full of butterflies: dark-brown Ringlets (Aphantopus hyperantus), brown-orange Meadow Browns (Maniola jurtina), little orange-grey Small Heaths (Coenonympha pamphilus), Painted ladies (Cynthia cardui), shimmering Common Blues (Polyommatus icarus) and a few Green-veined Whites (Pieris napi).

Like many members of the Lycaenidae, the larvae of the Common Blue have an association with ants - the larvae produce a sticky secretion which ants find attractive and the larvae, in turn, recieve a degree of protection from the ants. Its scientific name means 'many-eyed icarus' (Poly = many + ommatus, from Greek omma = eyed, and icarus = from Greek mythology - who failed in his attempt to escape imprisonment; using wings made from feathers and wax; when he flew too close too the sun).

The leaves and young flowers of Red Clover can be eaten raw or cooked and the seeds can be sprouted for use in salads, soups etc. Red Clover, being a legume, is able to fix nitrogen through its symbiosis with Rhizobium bacteria found in root nodules.

Also flowering right now are Marsh Hawksbeard (Crepis paludosa) and Catsear (Hypochoeris radicata) - just below the Test.

Mouse-ear Hawkweed can be easily identified by its solitary lemon-yellow flowers held atop erect, leafless stems, and by its hairy leaves held close to the ground in a basal rosette. This plant was traditionally used to treat a variety of respiratory complaints such as asthma, bronchitis and whooping cough, although the effectiveness has never been proven scientifically. It is known to be strongly diuretic.

Wild Pansy (Viola tricolor)

Also known as Heartsease, the Wild Pansy is the ancestor of the garden pansy and is highly variable in colouration. The flowers and young leaves (high in vitamins A & C) can be eaten raw in salads.

At the Test there was the usual flock of Reed Buntings (Emberiza schoeniclus).

I explored the far side of the Test, along the crumbling old dry stone wall and managed to catch a plump, pregnant Common Lizard (Lacerta vivipara). No Slowworms though :(

I crossed the heath to the North of the Test and continued towards the Greenside Reservoir where I took a detour around to avoid a group of teenage boys with quadbikes. The reedy edges of the Greenside were buzzing with damselflies - Large Red (Pyrrhosoma nymphula) and Common Blue (Enallagma cyathigerum).

Common Blue Damselfly (Enallagma cyathigerum)
Common Blue Damselfly (Enallagma cyathigerum) male


The Common Blue Damselfly (Enallagma cyathigerum) can be distinguished from similar species by the characteristic triangular black marking on the 2nd abdominal segment (pointing tailwards). This is refered to in the scientific name: 'cup-bearing' (Cyathi = cup/goblet in Greek + gerum = to bear/carry). It also has broad antehumeral stripes and is a brighter blue than similar species

There are at least 9 species of dragonfly & damselfly in West Dunbartonshire. I have found the best sites to be: the Greenland Reservoirs, the Lily Loch, Burn Crooks valley, Little Round Top, the Test, the disused mines near the Kilmannan Reservoir, and the Forth and Clyde Canal.

Hairy Stonecrop (Sedum villosum) was growing on the Western bank of the Greenside.

Because I love rusty metal (!):

I went to have a look at the young forest (part of a native woodland regeneration scheme) between the Greenside and the Jaw/Cochno. The grasses have grown luxuriously thick because the tall deer fence keeps out deer, sheep and most humans. The forest is still at a shrubby stage - an intermediate habitat which will attract species of its own.

While I was walking, a family of Whinchats (Saxicola rubetra) followed me along the fence. In the grass I found a large Common Toad (Bufo bufo). Lousewort (Pedicularis sylvatica) is flowering here.

The air was heavy, hot and humid and the sky overcast. I never get used to this sticky almost-tropical weather that we rarely experience in Scotland. It began to rain and the cool raindrops were so refreshing!

Snowy white, magenta-speckled Heath Spotted Orchids (Dactylorhiza maculata) were growing amid the damp grasses.

I was mobbed by a pair of very loud Common Gulls (Larus canus) at the Cochno Reservoir, so I presume they must have a nest nearby. I stopped at the Northern tip of the Cochno Loch, where the little burn emerges from the forestry plantation. Here I found plenty of Small Pearl Bordered Fritillaries (Boloria selene) and decided to spend the rest of the day photographing them.

This species, along with Green Hairstreaks and Common Blues, are my favourite butterflies. The upper-sides of their wings are bright orange with delicate black latticing, trimmed with cream, and the under-sides are patterned like a mis-matched jig-saw in shades of white, cream, gold and rusty-orange. I followed them devotedly as they went from thistle to thistle, dancing with each other and landing every now and again on Bracken fronds to bask.

I found another Common Lizard at the top of the Cochno Reservoir just before I headed home.

Back at my parent's house there were 2 Peach Blossom moths (Thyatira batis).

The Saltings - Local Nature Reserve, West Dunbartonshire

This morning I visited the Saltings in Old Kilpatrick to take part in a bird survey. The Saltings is an area of marshy meadow and mixed woodland which lies between the River Clyde and the Forth & Clyde Canal, below the Erskine Bridge. It is West Dunbartonshire's only nature reserve and recieved that designation fairly recently.

In the brilliant sunshine Ringlet butterflies (Aphantopus hyperantus) fluttered above the multicoloured meadow flowers. Tall dense-flowering spikes of orchids were everywhere in vivid shades of magenta and pink. Closer inspection revealed these to be Common Spotted (Dactylorhiza fuchsii), Northern Marsh (Dactylorhiza purpurella) and many which looked suspiciously like fuchsii x purpurella hybrids.

Nothing too unusual on the birding front - some Blackcaps (Sylvia atricapilla) could be heard calling and there were some warblers flitting about which may have been Whitethroats. Standing, silently frozen, by the edge of the canal, was a very rufous-brown Roe buck (Capreolus capreolus) with a fine set of antlers. Further along we spotted a Grey Heron (Ardea cinerea) which took off hastily. On the path we found a dead Common Shrew (Sorex araneus).

There were many Blue-tailed Damselflies (Ischnura elegans) along the canal.

Common Valerian (Valeriana officinalis)


Valerian root has sedative effects and has been used to treat insomnia, anxiety and as a pain-reliever. This plant is also a cat attractant (containing actinidine) with effects similar to catnip.

Kilpatrick Hills, West Dunbartonshire


I took another short after-work walk in the Kilpatrick Hills - around Little Round Top and the Test.

The marshy meadow at Little Round Top is full of Common Spotted Orchids (Dactylorhiza fuchsii), which are very photogenic!

Marsh Stitchwort (Stellaria palustris) is also flowering at Little Round Top.

The slope below the Test is covered in Heath Speedwell (Veronica officinalis) and Eyebright (Euphrasia sp.). I had to take a detour to avoid a herd of cattle with their youngish calves (which was a bit of a drag but I'd rather not take any chances).

Eyebright (Euphrasia arctica x nemorosa?)


This Eyebright (above) is possibly Euphrasia arctica x nemorosa, but only an expert could say for sure. This genus of tiny, near-identical semi-parasitical plants are named after their traditional use in the treatment of eye problems.

The Large Black Slug (Arion ater) is a very common species in the Kilpatrick Hills and is often found on damp grasses during the day. When disturbed, these slugs will contract and rock gently from side to side in a strange fashion. They also exude a thick sticky mucus which is very difficult to wash off. Although there exists a less common brick-red colour form, normally this species is jet black (as indicated by its scientific name: ater = coal-black).

At the Test a quick search underneath stones revealed a Palmate Newt (Lissotriton helveticus) and a large Common Frog (Rana temporaria) with a distinct purplish tinge and beautiful gold flecked eyes.

Kilpatrick Hills, West Dunbartonshire

After work I went for a short walk on the Kilpatrick Hills, there has been a massive influx of Painted Lady (Cynthia cardui) this year and I spent at least an hour chasing through meadows after them. These butterflies are very flighty and not easy to approach and I was only able to photograph them when they landed to bask.

The Painted Lady is a migratory butterfly and many of the adults we see in the UK have travelled here from North Africa.

In the marsh at Little Round Top there were lots of delicate little blue damselflies: Coenagrion puella. This species can be easily distinguished from the other blue damselflies by the U-shaped black marking at the base of the male's abdomen.

Whilst photographing damselflies, I heard an insistent peeping coming from a hole in an Elder branch. On closer inspection I found the source of the noise - a nest full of nearly-fledged Blue Tits (Parus caeruleus)!

I waited a distance back and hid in the Yellow Flags (and nettles!). The parents duly returned and resumed the constant ferrying of caterpillars into, and white poop-sacs out of, the nest-hole. I very much wished I had brought my tripod with me in order to take a better picture, but it would just have added to the weight I was carrying.

Blue Tit (Parus caeruleus)


Around Little Round Top there are thick Rhododendron ponticum bushes - an extremely invasive introduced species (the large evergreen leaves block out sunlight and so nothing can grow underneath these shrubs). The whole plant is poisonous.

Rhododendron ponticum


Yellow Flag (Iris pseudacorus)


The root of Yellow Flag (Iris pseudacorus) is emetic, cathartic and can cause severe gastric disturbance if consumed.

The hawthorns are still lushly blanketed in gorgeous snowy blossoms:

Pignut (Conopodium majus), Tall Ramping Fumitory (Fumaria bastardii), Wild Pansy (Viola tricolor) and Heath Speedwell (Veronica officinalis) are all flowering around Little Round Top.

I walked to the Test (a marshy area South West of the Greenside Reservoir) where you are almost guaranteed to see a flock of Reed Buntings (Emberiza schoeniclus), and today was no exception. Some Ravens (Corvus corax) could also be heard croaking and cawing hoarsely in the distance.

I found this caddis fly (Micropterna sequax) at the edge of the stream:

Caddis flies (Trichoptera) are closely related to Lepidoptera (moths and butterflies) and have aquatic larvae which build protective cases from riverbed debris.

At the Test I searched beneath stones and found a Common Lizard (Lacerta vivipara) and 2 Palmate Newts (Lissotriton helveticus).

This lizard's pale yellow, unspotted belly indicates that it's a female.

And for comparison, the underside of a Palmate Newt:

Palmate Newt (Lissotriton helveticus)

The Palmate Newt (Lissotriton helveticus) is the smallest of the three newt species native to the UK and is very similar to the Smooth Newt (Lissotriton vulgaris). In its terrestrial, non-breeding stage the Palmate Newt can be distinguished by its pinkish-white, unspotted throat (Smooth Newts have white throats with black spots) and by the presence of two small tubercles on the soles of the feet (females only). During the breeding period (aquatic stage) the male Palmate Newt develops an unwavy ridge along his back, a long tail filament and black webbing on the hind feet. In contrast, the male Smooth Newt develops a wavy crest from head to tail and is heavily black spotted.

Also at the Test were a pair of Wheatears (Oenanthe oenanthe) and a female Grey Wagtail (Motacilla cinerea).

Wharncliffe Heath, Sheffield (ENGLAND!)

I went to Sheffield to visit some friends and made a trip to Wharncliffe Heath with Richard, to look for Nightjars (Caprimulgus europaeus) and bats (I got a loan of a heterodyne bat detector!).

Wharncliffe Heath is a VERY small area of heathland (about the size of a large field) with oaks dotted through it. The surrounding area is a patchwork of old oak/birch woodland (with lots of bluebells) and sheep fields. We walked through the woodlands from the Wharncliffe Arms, in the direction of the Wharncliffe Crags. The woodland was full of Speckled Woods (Pararge aegeria) and some were landing on muddy river banks to drink. Green-veined Whites (Pieris napi) were also on the wing and we found a rather ragged-looking Peacock butterfly (Inachis io).

The Wharncliffe Crags are popular with rock-climbers and are very dramatic. The rocks were baking hot, so we sat in the shade of the trees to eat our lunch.

There were lots of Green Tiger Beetles (Cicindela campestris) hurriedly scurrying along the sandy path ahead of us.

We walked over the sheep fields as we had time to kill before dusk. Perching on a dry stone wall there was a plump Red-legged Partridge (Alectoris rufa).



Once the fiery-orange sunset had faded, we began doing a circuit of the heath with the bat detector switched on. After about 30 minutes we began hearing our first bats! The sound they emitted was like a sputtering, wet-slapping, clicking sound. It took us awhile to get the hang of using the bat detector - estimating the frequency peak and range was difficult. The bats we heard were definitely one of three Pipistrelle species: Common Pipistrelle, Nathusius' Pipistrelle or Soprano Pipistrelle.

In the half-light we could see Woodcock (Scolopax rusticola) circling above our heads and uttering 'tssick tssick!'. This shy bird is an unusual species of wader (Scolopacidae): being both a woodland species and nocturnal.

Soon the sky became pitch-black and we took our torches out. We waited until 10:30pm and then, just as we were thinking about heading home, we heard our first Nightjar! At first the churring was intermittent and seemed to be a single Nightjar but after awhile the churring was coming from several directions. We walked in the direction of the nearest churring but, in a grasshopper-like fashion, the churring stopped as soon as we came close and restarted again further away! Chasing nightjars in the dark is like following will o' the wisps!

It was impossible to work out which path we had taken through the forest as there were so many unmarked intercrossing paths on the map. The path we chose took us a longer route and we ended up walking along the side of the railway line, looking for the crossing which would save us time and allow us to catch the last bus home. Walking through the rough gravel took ages and eventually we had to concede defeat and we scrambled up the side of a railway bridge into Oughtibridge, where we phoned for a taxi outside The Cock Inn (feeling like prank-callers!).

Balfron to Dumgoyne, Stirling


I got lost. That pretty much sums up today's walk :(

With the intention of walking from Killearn to Stockiemuir, I took the number 10 firstbus (Glasgow to Balfron) and got off at Blane Smithy roundabout. Instead of taking the road to the left, I took the road straight-ahead (Northwards). To make matters worse, I forgot to bring my map.

I followed the A81 up to Gartness where there were many fields full of Lapwings (Vanellus vanellus) and Curlews (Numenius arquata). In flight you can see the lapwing's distinctive large rounded wings.

When I reached Killearn Bridge I was able to leave the road and have my lunch on the banks of the River Endrick (and have a wee look for Otters!). Plenty of Lapwings nesting here too. Swifts (Apus apus) reeled through the air above, swinging low over the river in pursuit of insects.

Once I reached Balfron it was clear that I had taken the wrong turn-off, so I went back the way I came. Along the way I came across a dead Tawny Owl (Strix aluco) on the road.

Just after Blane Smithy Roundabout, heading Southwards, I suddenly heard the loud peeping of baby birds. The calls were coming from a chiselled hole, high up in an oak tree. I watched the nest hole and didn't have to wait long for a Great Spotted Woodpecker (Dendrocopos major) to return. I had to stand a short distance from the tree for the female to enter the nest-hole (she was very wary of me).

Further along I took a detour to look at a little forest on the banks of the Endrick which was carpeted with delictae white Ramsons (Allium ursinum), also known as Wild Garlic. This plant is a wild relative of the cultivated Garlic (Allium sativum) and is very edible!

Ramsons (Allium ursinum)


In the sheep fields below Dumgoyne were more nesting Lapwings and, just at the roadside, a loudly piping Oystercatcher (Haematopus ostralegus) which tried to lead me away from its clutch of speckled eggs.

Shortly after this I managed to hitch a lift to Milngavie train station, where I caught a train home.
