Sticky Bud

Flaky bark and even flakier tree recognition: I take a closer look at the tree that I photographed on Friday and, although the bark is flaky, it isn’t as flaky as that of London Plane: it’s Horse Chestnut, which probably explains why the bark is so polished; it’s been climbed by generations of conker collectors.

At this time of year, the swelling buds are almost as distinctive at the autumn conker fruits. The bud scales are red-brown and sticky and beneath them are the shield-shaped scars where last year’s leaves were attached.

The lenticels that dot the twigs are raised pores which allow for gaseous exchange.

Horse Chestnut

 These boughs of a Horse Chestnut*, snaking out over the Middle Lake at Nostell Priory have been polished by generations of young explorers so that the scaly bark resembles the skin of a serpent.

*Not London Plane, as I’d said in the original version of this post. I went back and checked the buds and they’re big, brown and sticky.

The First Day of Spring

Hellebore: Noodler’s Ink won’t dry when it’s so cool.

Today is the first day of spring, at least meteorologically speaking, but, with a cool breeze this afternoon, the temperature here in the back garden is a wintry 45°F, 7°C.

As a change from Apple Pencil and iPad in the comfort of my studio, I decide to spend an hour drawing in the garden.

The Noodler’s Ink in my Lamy fountain pen won’t dry when it’s so cool, so I move on to a UniPin fine line fibre tip.

Blackbird Singing in the Dead of Night

Perhaps encouraged by the supermoon – which was 10% brighter than the average full moon – a blackbird was singing at 2.30 this morning.

Long-tailed tits feed on the fat-balls a couple of yards away from me as I draw the hellebore.

wood pigeon flies overhead, spots me and veers away.

blue tit eyes me suspiciously from the feeding pole.

 

Snowdrops

The fibre tip isn’t fluid enough for me to work as quickly as I’d like on sketch of a log pile by the holly hedge, so I try my Lamy Safari fountain pen. Lamy ink isn’t waterproof, so it runs into my watercolour but I try to make the most of the effect.

Snowdrops do well around the pond and under the hedge at the end of our garden.

Coxley Beck

This digital painting has turned out looking like the starting point for one of my acrylic on hardboard paintings, before I’d started adding details of tree, water and ferns.

Coxley Beck is running opaque with sediment where it passes through an old mill race at Horbury Bridge. I’ve draw this on my iPad Pro, using an Apple Pencil in the Clip Studio Paint program.

I pasted a photograph that I’d taken this afternoon into the lowest layer of my Clip Studio Paint document, then added a layer for pencil above it. So that I could see where I was going with the pencil, I partially faded out  the photograph by using the opacity slider for that layer.

I traced the trees and the line of the beck in pencil, then hid the photograph by clicking its eye symbol in the layer palette and drew using the pen tool, using my pencil tracing as a guide.

Paint Layer

Once I’d finished with the pencil layer, I hid it and added a new layer for paint. In order not to paint over my pen lines, I added the paint layer below the pen layer.

As I worked, I kept referring back to the photograph layer, now with the opacity slider set back at 100%, and used the eye-dropper tool to sample colour. I couldn’t always get the colour that I wanted, so I also used some of the standard swatches and the colour wheel.

In the odd spots that I hadn’t painted, the default white background of what Clip Studio refers to as ‘paper’ showed through, making Coxley Beck look more sparkly than it actually does this afternoon, so I added a background layer of a suitably muddy brown.

Pen, initial pencil sketch and first attempts at adding colour.

It reminds me of when I painted in acrylic and I’d start by painting the whole canvas in a neutral light grey, so that I wasn’t misled when mixing tones by a brilliant white background.

I used various digital pens, finishing up with the textured pen and various versions of the watercolour brush, including dense watercolour.

I look forward to trying the technique with another subject.

Petty Spurge

Petty spurgeEuphorbia peplus, is a common weed  of gardens and waste ground but its tiny green flowers look quite exotic in close up. Those horned glands give it a hint of the extra-terrestial.

The winged capsules are the female parts of the flower. There are three here, the central one much larger than those at top and bottom of the picture. Each capsule has a tuft of stigmas (five on the lower one).

Appropriately, the male flowers are the ones that are sporting the stag’s horns (which are glands). Again, there are three in the photograph and I think that on the tips of the stamens of the top one there’s a hint of yellow pollen.

The the small beak-like fleshy ‘leaves’ that can be seen clasping the top and bottom flowers are a structure that is special to euphorbias called the cyathophyll. I think that must be a botanical term for ‘cup-like leaf’ because phyll means leaf and cyathos is derived from a Greek word meaning ‘A cup or ladle used for drawing wine from a bowl’.

The larger ‘leaves’ clasping each flower are bracts, which look very similar to the leaves in this species. Each umbel of flowers has three rays (primary branches).

The petty spurge is not thought to be a native to the British Isles but is believed to be long-established here, since before 1600.

Carrion Crow

There’s often a carrion crow on the old felled sweet chestnut trunk near the Lower Lake bridge, feeding on grain that’s been left there and frequently being photographed. You can see in my photograph that it’s stuffed its crop with grain.

A few rooks feeding alongside jackdaws on the turf in Obelisk Park also have full crops, but they are more likely to be feeding on earthworms and insect larvae, such as leather-jackets: the caterpillar-like larvae of the crane fly.

grey squirrelUnder a yew near the Menagerie seven grey squirrels have gathered. They’re turning over the leaf litter and stopping to nibble at frequent intervals. One appears to have found half a nut, probably an acorn that it – or another of the squirrels – had hidden during the autumn.

We disturb the adult grey heron yet again. This time it was hoping to be left in peace at the top end of the lake beneath the Cascade Bridge. It takes off, clearing the clapper stones of the Druid’s Bridge with inches to spare.

 

The flock of fieldfares are still around. Wigeon have left the now completely ice-covered field pool. There’s a pair on the Middle Lake, along with two pairs of gadwall, tufted, the usual mallards and swans and an increasing number of goosanders, some swimming in pairs.

There are more wigeon on the ice-free Upper Lake, which isn’t accessible from the Park.

As we walk along the edge of Top Park Wood, a kestrel wheels from tree to tree ahead of us.

Pleurococcus Algae

On the northern half of the trunk of an oak by the Lower Lake a coating of powdery green algae shows up in the morning sunlight. It is absent from the sunny south side of the tree so, if you’re trying to do a bit of natural navigating and you’re lost deep in the forest this could help you to orientate yourself.

This is probably Pleurococcus or a very similar-looking species of green algae. Seen through a microscope, Pleurcoccus is a globular single-celled alga with a thick cell wall to help it resist desiccation. The individual cells are slimy and stick together to form the powdery coating.

Green algae contains two kinds of chlorophyll: Chlorophyll A and Chlorophyll B. The two molecules work together; Chlorophyll A absorbs blue-violet and orange-red light while B extends the spectrum by absorbing blue light. The green that we see is the light that doesn’t get absorbed.

Drift Ice

There’s a thin layer of slushy ice on a sheltered section of the canal, in the shade and shelter of the sandstone escarpment of Hartley Bank Woods, but some shards of thicker ice have been blown alongside the concrete canal bank and gathered in shards as they’ve piled up against a clump of grass at the water’s edge.

This is probably reed canary-grassPhalaris arundinacea, which sometimes gets the nickname ‘canal grass’. I’ve even heard it described as ‘designer phragmites’, an alternative to the common reed, Phragmites australis, where space is at a premium!

Rain soon followed this morning’s snow: there’s faint rainbow near the centre of this photograph.

A cormorant flies up from the marshy field known as the Strands. What open water there is here appears to be entirely ice-covered. The small lagoon by Beeston Bridge at the foot of the Balk is also frozen solid so the resident moorhens have lined up on the river’s embankment to peck amongst the rough grasses there. It’s probably marginally warmer over by the river.

 

 

Call of the Wild

11.45 a.m.: As I clear the snow from our driveway I hear an approaching cachophony: an unfamiliar sound . . .  A little dog? A radio? The hooter of a child’s pedal car?

Soon a skein of eighty grey geese appears, three or four hundred feet above the rooftops. It’s a different sound to the argumentative sounding Canadas that we’re more familiar with; slightly deeper and, I think, a wilder kind of call.

They’re heading in the same direction as the skein we saw at breakfast time the other day: south east; so perhaps towards the Humber or the Old Moor RSPB reserve?

Squirrels in the Sycamores

Stripped bark

Against a clear blue sky, the winter sun picks out slashes of creamy white on the top branches of a tall sycamore, which I suspect are the result of grey squirrels stripping the bark. There’s no sign of damage on the adjacent oak but its bark, loaded with tannins, is probably not as nutritious as that of the sycamore.

The sycamore is probably the nearest that the squirrels can get to the tastier-sounding sugar maple, which, like the grey squirrel, is a native of North America.

In the topmost branches of another sycamore, a squirrel leans out to pick off buds from slender twigs which it eats, one after the other: a healthy snack.

Hornets’ Nest

Hornets at the nest hole, 13 August, 2017.
New shoots springing from the old ash stump: a natural equivalent of a coppice stool.

In the summer and early autumn, hornets nested in an old ash trunk in the parkland near the Pleasure Grounds. By mid-autumn the trunk had rotted through at the base and come adrift from its roots but it was prevented from falling towards the path by the surrounding stout stems, which had sprung up around it: a natural equivalent of coppice shoots.

Frass in old cavities in ash.

Now it has fallen back in the other direction and it lies on the ground. I can’t see the cavity that contained the hornets’ nest – it’s probably hidden on the underside – but all the timber is riddled with tunnels, some of them stuffed with frass, which has set hard like fine-textured chipboard.

Parkland Birds

Fieldfares and starlings

The fine cold morning has brought in fieldfares, twenty-five of them. We’ve been expecting them to turn up here on the grassy slopes of the Obelisk Park.

Also back this morning, on a small, partly iced over pool in the corner of a grassy field just beyond the park boundary, are fifty wigeon, which often graze on the short turf here.

Joining the regular great tits, blue tits, coal tits and robins in the lakeside woods is a goldcrest, which, thanks to its size – along with the firecrest, it’s our joint smallest British bird – can inspect the slenderest of twigs.

A jay flies up into a sapling and we notice that it seems to be keeping an eye on a kestrel, a falcon of open spaces which seems a bit incongruous in this woodland setting.

It settles for a while, looking out over the lake. We rarely get such a good view of a kestrel and I make a mental note of its yellow beak, tipped in black; the tear-drop shaped dark patch beneath its eye; and the russet tan plumage of its back, speckled with dark brown.

As it flies to another perch, it shows pale grey tail feathers, banded with dark brown, almost black, at the tips.

Mallards and Mute Swans

Midwinter is hardly over but already, on the ice-fringed Lower Lake, the mallards have mating in mind. A drake head-bobs as he swims around the duck prior to mating.

As we round a corner by a lakeside bench, we disturb a heron. It must be getting tired of seeing us as we disturbed it here, same time, same place, yesterday morning.

One of the two cygnets of the mute swan family on the Middle Lake has now lost the last of its grey feathers. It’s now almost an adult, except for its bill which gives it away as a juvenile: this looks as if that has been given a coat of grey undercoat prior to the final coat of orange, which looks so striking on the adults.

The other cygnet still has a some grey on its back, as do the four cygnets of the swan family on the Lower Lake. They seem to be spending more time away from the adults, this morning at the far end of the side arm of the lake.

At the lakeside, a cigar-shaped seed-head of reedmace disperses a couple of wisps of its downy seeds. It has been calculated that one stalk can produce 200,000 seeds.

That Old Chestnut

There’s a heavy crop of oyster mushroom (above) on some sweet chestnut logs, the entire trunk of a felled tree, which have been left as a habitat in Thornhill Park. Oyster mushrooms are currently £10.80 per kilogram at Sainsbury’s, so there must be hundreds of pounds’ worth here, although some are a bit past their best.

The logs are also sprouting honey fungus (left), which is said to be edible when young.

On the stump itself, the common bracket fungus of dead wood, Trametes versicolor is growing. The brackets are paler around the edges.

This silver birch, down by the canal near the Figure of Three locks, was catching the sun. I’ve added a watercolour filter in Photoshop to bring out the texture of the diamond-shaped scars of its bark. Hopefully, I’ll be getting down to actually painting some watercolours in the new year!

I feel that I can already tell that the days are getting longer and it’s good to think that, in two months time, dogs mercury and lesser celandine will be springing up on the hedgebanks with coltsfoot appearing on disturbed ground.

For the moment though, the only conspicuous flowers are those of hogweed.

The rainbow didn’t show up in my photograph as much as it did in real life, so I’ve boosted it a little in Photoshop.

Hazel catkins, as yet unopened, are now prominent in the hedgerows.

There was a soft arc of a rainbow over the valley this morning as we set off across the fields via Smithy Brook to Thornhill.

Boxing Day Walk

I’m pleased that over the Christmas period we’ve managed to get out into our local countryside to walk our regular ten thousand steps because a news item in this month’s Healthy Food Magazine reports that researchers at The University of British Columbia have:

“found a link between getting a nature top-up with an increase in general happiness and health during a two-week study. Participants were split into three groups: a control group, a group noting down human-made objects and those documenting nature finds. It was the last group that experienced the biggest boost in self-perceived wellbeing.”

There was me thinking that catching up with my family and eating lots of Christmas cake and mince pies was what had given me a seasonal glow of wellbeing. I should have realised that it was getting my boots muddy and observing rainbows, fungus-covered logs and birch bark.

Who wouldn’t be happy doing that?
