Kilpatrick Hills, West Dunbartonshire

My walk today took me from Duntocher to Little Round Top and then the Test (the marsh to the East of the Slacks).

The Bluebells haven't yet begun to flower. I've noticed that the spring flowers are very late this year, probably due to the very harsh winter. At Little Round Top there are good numbers of Orange-tip butterflies.

marsh marigold
Marsh Marigold (Caltha palustris)

Marsh marigold is not related in any way to garden marigolds (which belongs to the daisy family: Asteraceae); rather, it is a member of the buttercup family (Ranunculaceae).

Marsh Marigold's scientific name Caltha palustris is a straight-forward Latin translation of its common name: 'Marigold of-marshes' (Caltha = marigold, and palustris = of marshes).

The orange, fibrous roots of Yellow Flag (Iris pseudacorus) are poisonous but supposedly yield a black dye (when mixed with iron sulphate).

ash bark
Ash (Fraxinus excelsior) bark

Ash has a rough, grey bark with fissures forming a criss-crossing pattern of Xs.

Little Round Top wood is an impenetrable tangle of thorny Sloe bushes, massive Ash trees and thickets of Elder and Hazel. Many of the gigantic Ash trees have succumbed to rot and have fallen down in the last few years, their colossal trunks form a complex head-high obstacle course. As I sat on the mossy bark of one of these felled leviathans, I watched Treecreepers scaling the cracked-skin of still-standing trees and Long-tailed Tits zipping about high in the canopy.

wavy bittercress
Wavy Bittercress (Cardamine flexuosa)

Wavy Bittercress (Cardamine flexuosa) can be distinguished from its close relative Hairy Bittercress (Cardamine hirsuta) by the presence of 6 stamens per flower (see above photo: Hairy Bittercress has 4) and by the position of the young seed-pods BELOW the flowers (Hairy Bittercress has seed-pods which extend ABOVE the level of the unopened flowers).

Both Bittercress species are edible - the leaves and flowers have a hot, peppery taste.
bracken
Bracken (Pteridium aquilinum)

black poplar bark
Black Poplar hybrid (Populus nigra x ?)
Each tree species has its own distinctive bark texture and colour, a characteristic pattern of ridges, like a fingerprint.

The Black Poplar hybrid (Populus nigra x ?) growing below Little Round Top is a non-native tree. The bark is grey, fissured and heavily 'crackled' like pottery glaze. There are also many 'eyes' in the bark.

The fresh bark of all poplars (and willows) contains salicin (C13H18O7), an alcoholic β-glycoside, which is similar in structure to acetylsalicylic acid (aspirin) and has pain-relieving, fever-reducing, anti-inflammatory and anti-septic properties.
ground ivy
Ground Ivy (Glechoma hederacea)

Ground Ivy (Glechoma hederacea)
When crushed, Ground Ivy releases a powerful herby aroma, which I find very pleasant. Herbal tea can be made from the leaves, which are purported to be anti-inflammatory, astringent and aid digestion. In the past, this plant was used to flavour beer instead of/alongside Hops.
burdock

Climbing under some of the fallen tree trunks, I managed to get Burdock burrs on my clothing: they are surprisingly difficult to extract, the voracious hooks burrowed into my fingertips as I tried to remove them. These were the inspiration for George de Mestral's Velcro.

Burdock roots are edible when cooked and are often used in Asian cooking.
In Japan, Burdock is known as 'gobo' and is used to make a number of dishes including 'kinpira gobo': http://justbento.com/handbook/recipes-side-dishes-and-space-fillers/classic-kinpira-gobo.

Of course, the roots can also be incorporated into soups and stir-frys, or mashed & mixed with flour and fried in a similar fashion to potato scones.

Burdock roots contain inulin, a polysaccharide which cannot be directly digested by the body (gut bacteria digest inulin and release fatty acids which we can absorb). Because of this indirect digestion (gut bacteria release methane through fermentation), inulin may cause bloating/wind in those unaccustomed to it.

Hazel (Corylus avellana) has a beautiful bark: pale greyish-brown and smooth, with a slight metallic sheen and a delicate morse-code of ridges.

Elder has a similar bark pattern to Ash, but the bark is dull, beige-brown and has a distinctly corky feel to it. Elder wood is very light-weight since most of the interior is filled with a spongy white pith.
elder bark
Elder (Sambucus nigra)
On my way from Little Round Top to the Test, a Brown Hare lept up from the marshy grass and galloped off. It left a flattened patch, or 'form', in the grass, from which I was able to collect a sample of hair/hare.

A pair of Whinchats (Saxicola rubetra) are breeding at the rocky Northern end of the Test:

Whinchat (Saxicola rubetra) female
Whinchats, like Wheatears, migrate to the UK from Africa for the summer months (in contrast, Stonechats remain all winter). The thrush family (Turdidae) has been largely reorganized in recent years and many species moved to the Muscicapidae (Old Word Flycatchers); including both Whinchats and Wheatears.

In the moorland North of the Test, I found this unfortunate wee fellow, a Common Shrew (Sorex araneus):

Common Shrew (Sorex araneus) dead

These tiny mammals are surprisingly fierce! As a child I remember finding a Common Shrew whilst turning over rocks in search of wildlife: it didn't try to run away, but stood its ground and bared every sharp little tooth in its head. I changed my mind quickly about capturing it! Shrews are solitary, coming together only to mate and defending their territories vigorously from other shrews.

The saliva of some shrew species is thought to contain a toxin which causes inflammation and a painful burning sensation, hence the Common Shrew's scientific name 'Sorex araneus': Sorex = shrew, and araneus = spiders (as in, venomous).
Accounts of shrew bites (mostly concerning the genus Blarina) can be found here (as well as some good shrew-lore!): http://members.vienna.at/shrew/cult-poison.html.

Edward Topsell's The History of Four-footed Beasts and Serpents, a bestiary published in two parts in 1607 & 1608, has this to say: "It is a ravening beast, feigning itself gentle and tame, but being touched it biteth deep and poysoneth deadly. It beareth a cruel minde, desiring to hunt anything, neither is there any creature that it loveth".

Kilpatrick Hills, West Dunbartonshire

Today was like two days rolled into one: I left early (4am), as I was getting a lift up to the Black Linn/Craigarestie for one of this year's Black Grouse counts.

No Black Grouse seen or heard by me, though my Dad was lucky enough to witness a lek of 6 males on Cochno Hill - a new lek site for the area!

Mostly, we just sat in the dark with our feet turning to blocks of ice and the cold wind slicing through us :(

All that could be heard were cuckoos, the twittering and warbling of small birds from the conifers, a pair of alarmed Mallards and the chortling, rattling "go-back go-back" of Red Grouse. Briefly, a Buzzard soared overhead and some Herdwick sheep (more about those later!) in the distance unwittingly mimicked Black Grouse. I had to keep stretching my legs to keep my feet from getting too painfully numb: it's amazing how the temperature drops at night...so much for my notions of going camping...

In the fields below Overton, East of Bowling, there was a small flock of grazing Shelduck.

After I'd been dropped off back in Duntocher (thanks Gillian & Gordon!), I had a few cups of tea and the weather (which had looked certain to be heavy rain) began to brighten up. Since it was only 10am, I decided to go back into the hills for a bit.

On this walk I followed the Humphrey Road to Haw Craig, past the quarry to the Auchentorlie Glen woods, onto the top of the Lang Craigs, then down the Overton Glen (following the river). On the way home I walked to the Humphrey via the Black Linn and Greenland Reservoirs and back down the Humphrey Road.

Swallows (Hirundo rustica) were perched on the barbed wire fence by the side of the Humphrey Road. The sunshine revealed the metallic blue-black of their backs.

I found a large Garden Tiger (Arctia caja) larva or 'wooly bear', at Haw Craig:

Sitting on the crest of the cliff, I could see into the wooded gully below: a Roe Deer buck (unawares of my presence), charged through the undergrowth, barking loudly.

Mystery warblers flitted about tantalizingly close. Orange-tips (only males), Small Whites and Peacock butterflies are on the wing.

Greater Stitchwort (Stellaria holostea) is flowering at Haw Craig:

Whilst crossing the short clumps of Broom at the North Western edge of the Haw Craig valley, a Common Lizard scuttled away under my feet.

Near the Lang Craig, I saw my first Wheatear (Oenanthe oenanthe) of the year:

Wheatear (Oenanthe oenanthe) male

Wheatear (Oenanthe oenanthe) male
The Wheatear's scientific name 'Oenanthe oenanthe' is latin for 'The-grape-of-the-wild-vine'...not really sure why!

On the top of the Lang Craig I saw a male Emperor Moth. Here also, there was a flock of Herdwick sheep:

Herdwick sheep (1 year old)
Herdwick sheep (1 year old)

The ancient Herdwick sheep is native to the Lake District fells of Cumbria (North West England) and is one of the hardiest sheep breeds: capable of coping with the harsh weather and poor-quality grazing on Cumbrian mountains in winter.

Lambs are born black and gradually lighten in colour - at one year old they are dark brown with white face and legs (at this stage they are known as hoggs or hoggets). Eventually they become 'hoar-frosted' slate grey with white head and legs. Only the rams have horns. The legs are chunky, strong-boned and have large knees. Herdwicks have dense, coarse wool with a high kemp and lanoline (oil) content, which makes it waterproof, quick-drying and highly insulative.

Bred to be territorial, they will not wander far from where they were born: a trait known as 'heafing'. They are kept mainly for their strongly flavoured meat. The coarse grey wool is not easily dyed and has little commercial value - it is mostly used for carpets, loft insulation and knitware.

For comparision, the usual sheep kept on the Kilpatrick Hills is the Scottish Blackface:

In the Overton Glen (banks of river) I found my second Common Lizard of the day! More Herdwick sheep also. Mossy Saxifrage was growing on the rocks at the edge of the stream.

On the way back home I passed the Black Linn - 3 Greylag Geese and a Mistle Thrush on the grassy bank.

The pair of Ravens from Haw Craig cronked at me as I walked back down the Humphrey path.

Raven (Corvus corax)

Further down the Humphrey Road I found Chicken of the Woods fungus growing on a rotten tree at the side of the road.

Chicken of the Woods fungus (Laetiporus sulphureus)
Chicken of the Woods fungus (Laetiporus sulphureus)
The Chicken of the Woods (Laetiporus sulphureus) is said to be one of the best edible mushrooms (I have no doubt it tastes better than the flavourless 'shop mushrooms'!). The scientific name means 'Pleasing-pores sulphury' (Laeti = pleasing/joyful + porus = pores, sulphureus = like sulphur).

Dandelion (Taraxacum officinalis)

Dandelion's scientific name means 'Of-disturbance used-to-treat' : Taraxacum = of disturbance (Greek), and officinalis = which translates roughly as 'used to treat/of medicinal use'(Latin). This refers to both the Dandelion's preference for disturbed ground/wasteland and its past medicinal uses.
Dandelion is one of the best edible wild flowers: the entire plant is edible and completely safe to eat! The only warning I would give is that Dandelion is strongly diuretic: don't eat large amounts if this bothers you (I am a chain-tea-drinker anyway!).

Eating Dandelions:
Leaves & Flowers:
The slightly bitter but very nutritious leaves can be eaten raw in salads or cooked. If you have pet rabbits, guinea pigs, gerbils, chinchillas or degus, they will appreciate dandelion (from a herbicide-free source!).

Roots:
When cooked these are said to have a 'turnip-like' flavour. They can also be dried, roasted and ground to make a coffee substitute (caffeine-free!).

Kilpatrick Hills, West Dunbartonshire

The aim of today's walk was to look for the elusive Emperor moth (Saturnia pavonia): the only member of the impressive Saturniidae family which is native to the UK. The nocturnal females are difficult to find when resting in the heather. The males, on the other hand, are diurnal with a very characteristic erratic flight pattern. They are difficult to approach: they have no need to feed and therefore, no need to land!

My dad and I walked along the Humphrey Road to the Humphrey reservoir, past the Lily Loch, to Burncrooks reservoir, to the Whangie, crossed Stockie Muir (following one of the unnamed rivers which cross the moor) and we ended our hike at Carbeth Inn.

Saw my first Swallows (Hirundo rustica) of the year above the fields at the end of Beeches Road (Duntocher).

At the Lily Loch we could hear the yickering calls of Little Grebes (Tachybaptus ruficollis): it seems likely that they will breed here again this year.

The sky was clear and cloudless and the sun blazingly warm. We took a detour along the edge of Burn Crooks valley to look for Adders, but found nothing: perhaps they haven't yet emerged from hibernation.

I know it's a bit lame, but I couldn't resist photographing this:

Marker indicating the location of Stop Valves (water mains) at Burn Crooks 

Strangely aesthetically pleasing...I've always been fond of azure-blue.

At the second dam at Burn Crooks, a pair of Grey Wagtails (Motacilla cinerea) were darting about.

As we crossed the moor to the South West of the Whangie, we spotted a male Emperor moth - too fast to photograph :(
At this spot we disturbed a male Roe Deer (Capreolus capreolus), still in its darker winter coat, which flared its white rump at us and effortlessly jumped a barbed wire fence and disappeared into the forest.

I collected some Roe Deer hairs from a 'deer couch' on Stockie Muir (where we disturbed another Roe Deer, a female). The coarse hairs were steely grey with brown/black-ticked tips and distinctive 'spongy' texture.

2 Red Grouse (Lagpus lagopus) on Stockie Muir and numerous warblers darting about in the decidous trees which line the Stockie Muir burns. Another male Emperor moth danced rapidly past us.

Wood Warblers (Phylloscopus sibilatrix) could be heard singing: their trilling calls somewhat resemble the sound of a coin spinning on a table.

Listen to the 'spinning coin' trill of the Wood Warbler here: http://www.rspb.org.uk/wildlife/birdguide/name/w/woodwarbler/index.aspx

The Stockie Muir Black Grouse lek was deserted, the short grass strewn with their black feathers. I took back a lyre-shaped tail feather to add to my collection.

Duntocher, West Dunbartonshire

This morning there were a pair of Collared Doves (Streptopelia decaocta) and a lone Woodpigeon (Columba palumbus) perched in the trees in my parent's garden.

One interesting feature of the pigeon family (Columbidae), which is unusual amongst birds, and is shared only by Flamingos and some Penguins, is the method by which they feed their young. Pigeons produce crop-milk: a secretion from the lining of the crop which is composed mostly of sloughed cells and is very rich in fat and protein. Both males and females secrete and regurgitate crop milk on which the young squabs are fed entirely until they are at least a week old (after which the parents feed them increasing porportions of mashed adult food).

Woodpigeon (Columba palumbus)
The Woodpigeon is by far the largest European pigeon species, weighing up to 520g. It can easily be distinguished by size, the white bands on its wings and by the white neck patches. The bill is pinkish-yellow and the eyes have pale yellow irises.

The Woodpigeon's scientific is latin for 'Collared-dove pigeon' (Columba = from Columbar = collar + palumbus = pigeon).

Collared Doves (Streptopelia decaocta)
Collared Dove (Streptopelia decaocta)
Collared Dove (Streptopelia decaocta)
The Collared Dove is small, slender pigeon with pale brownish-grey plumage and a black neck band. The bill is grey and the eyes are dark red. Weighing around 200g, it is considerably smaller and slimmer than the portly Woodpigeon.

The Collared Dove's scientific name mixes both Latin and Greek, meaning 'Collared-dove eighteen' (Strepto = wearing a collar/torque (Greek), peleia = wild dove (Greek) + decaocto = eighteen (Latin), literally ten-eight). 'Strepto/streptos' literally means 'twisted' in Latin, referring to the twisted strands of metal which make up a torque or neck collar.

The Collared Dove has expanded its range Westwards from Turkey and the Middle East over the last 40-50 years. In 1955 it nested in the UK for the first time and since then the population has rapidly increased: around 568,000 birds now breed here.

Kilpatrick Hills, West Dunbartonshire


Just a short walk today: from Duntocher to Little Round Top and then the Slacks. The increase in birdsong is becoming very evident!

The recently revamped RSPB website has sound clips for most species, very handy!

The snow has almost completely melted in the Kilpatrick Hills but the higher Campsie fells, to the East, are still very white:

Stag's Horn Clubmoss (Lycopodium clavatum)

Stag's Horn Clubmoss (Lycopodium clavatum) is purported to have various medicinal properties such as being analgesic (pain-relieving) and antirheumatic. However, this plant is known to contain the toxic compounds lycopodine (which paralyses motor nerves) and clavatine.

Its scientific name means 'Wolf-foot club-shaped'(Lyco = wolf + podium = foot, clavatum = club-shaped).

Kilpatrick Hills, West Dunbartonshire

Winter lingers on...the hills are almost flowerless and scattered with snow patches. Today I walked from Duntocher to the Mohican Woods (above the old curling pond), to Duncolm and then the Kilmannan Reservoir. The sky remained dark and overcast throughout the day but the rain held off.

Rusty metal
At the Eastern end of the Mohican Woods I put up 2 Woodcock (Scolopax rusticola) which were sitting silently amongst the leaf litter. The ground was scattered with their barred feathers. Soon after, I disturbed a Roe Deer (Capreolus capreolus).

The forest floor was covered with the yellowish-green flowers of Opposite-leaved Golden Saxifrage (Chrysosplenium oppositifolium).

Oops! I previously misidentified the above plant, assuming it to be young specimens of Sun Spurge.

At the top of the Mohican Woods, a flock of 12 Common Crossbills (Loxia curvirostra) landed on a Larch tree close to the path. They began feeding on the Larch cones and it struck me how large they are (for finches) and also, how strangely parrot-like.

Coltsfoot (Tussilago farfara)
I investigated the recently-felled pine forest (forestry commission) between Duncolm and the Kilmannan Reservoir. Piles of white bags ominously printed in red with 'Pesticide Treated', turned out to be filled with sapling trees (mixed native species) awaiting planting. Part of a native forest restoration project??


The roots of the upturned/felled trees formed 2 metres-high, earthen/turf wall along the edge of the forest:



On the Kilmannan there was a small flock of Goldeneye (Bucephalus clangula) and a pair of Mallards (Anas platyrynchos).

In the nearby pine forest I found a recently erected nestbox which, judging by the size of entrance, is intended for a large bird species (goldeneye? owls?).
