In Coldfall Wood

Dear Readers, we went for the first litter-pick of 2022 in Coldfall Wood yesterday. You might remember how I really like a bit of litter-picking – after a long day of sitting hunched over my laptop it gets me moving, gives me some fresh air and a new perspective, and makes me feel useful. It’s also good to compete inconspicuously with your fellow litter-pickers – we haven’t quite come to blows over who gets to ‘bag’ a crisp packet, but it can get pretty exciting, let me tell you. Anyhow, yesterday we rewarded by masses of blackthorn, whole bushes of it. It looked as if there had been a late snowfall, there was so much frothy white.

And, actually, there wasn’t too much litter – we haven’t had many warm days, but it has been the Easter Holidays so I was pleasantly surprised that there wasn’t much debris. Apart, that is, from along the fence-line between the playing fields and St Pancras and Islington Cemetery. Honestly? This is all piled up on the Cemetery side of the fence. We are in discussion with the management at the Cemetery so hopefully it will be removed soon, before it cascades down the slope and brains someone.

There are lots of baby horse chestnuts popping up in this area – I love their leaves. They remind me of little green hands.

We got several bags full of rubbish and then, as we crossed back across the ‘Everglades’ (the wet part of the wood), we saw this very confiding crow. At first I thought that he or she had some white feathers in her wings, but when we looked more closely, it’s clear that there’s some feather damage there. The bird can fly a bit, but it’s rather worrying. S/he looked at us with a curious eye, and hopped/flew over to the next stump when we seemed to be too close.

It’s always sad when you see a wild creature that’s been injured in some way – sometimes you’re able to catch them so that you can take them to a vet or a sanctuary, but sometimes they’re just about agile enough to evade your advances. My friend A may well pop back today to see how the crow is doing, so watch this space. At the very least, these are intelligent and adaptable birds, so fingers crossed.

Wednesday Weed – The Wayfaring Tree

Wayfaring Tree (Viburnum lantana)

Dear Readers, it’s always fun to ‘meet’ a new native plant, and so I was very chuffed to come across this wayfaring tree in Camley Natural Park on Saturday. It’s one of those plants that I think I’ve walked past a hundred times, but have only just noticed. It has a kind of dusty, straggly look about it, but close up it reveals many beauties.

At first glance, I thought it was a guelder rose, but the leaves are clearly different, being oval and heavily veined. Plus, where guelder rose has flowers that look like mini-hydrangeas, the wayfaring tree has waxy flowers with a sweet scent, though the jury is out on whether it’s delightful or cloying.

The wayfaring tree was named by the herbalist Gerard, who noticed that it grew alongside the paths on the road from London to Wiltshire and so,if you saw one, you knew you weren’t far from civilisation. Another old name for the plant was ‘hoarwithy’ – hoar meaning ‘silvery-grey’, and referring to the hairs on the underside of the leaves, and ‘withy’ meaning ‘a pliable stem’. The stems of the wayfaring tree were used to tie up bundles of hay and straw, and also to make whip handles, leading to yet another name  – ‘twist wood’.

The wood was also used to make arrows: poor old Ötzi, the bronze age man found dead in the Austrian Alps in 1991, had a whole quiver-full of arrows made from the wayfaring tree, but presumably he didn’t get a chance to use them before he was murdered.

The berries are very attractive, shiny red and black, but they are also mildly poisonous, although this doesn’t deter the birds. Waxwings and thrushes will eat the fruit, but as it isn’t their favourite food it will often linger into the winter, so it’s available when everything else is gone.

The berries and in particular the bark contain high levels of tannins, which have been used to treat asthma, sore throats, gingivitis and smoker’s cough, usually as a gargle. In Eastern Europe it has been used to produce a yellow dye, and as an ink.

The wayfaring tree can be found right across Europe and Asia, and here it features in a Japanese print, featuring a rather splendid magpie.

And finally, a poem. Although it isn’t directly about the wayfaring tree, it is about wayfaring, and I can think of several of our leaders for whom this would be most apposite. It’s by Stephen Crane, the American poet best known for the novel The Red Badge of Courage. See what you think….

The wayfarer, by Stephen Crane

The wayfarer,
Perceiving the pathway to truth,
Was struck with astonishment.
It was thickly grown with weeds.
“Ha,” he said,
“I see that none has passed here
In a long time.”
Later he saw that each weed
Was a singular knife.
“Well,” he mumbled at last,
“Doubtless there are other roads.”

Is It Okay to Feed Bread to Waterfowl?

Dear Readers, one of the highlights of the summer holidays when I was a child was heading off to Wanstead Flats to feed the ducks. Off we’d go with a plastic bag full of stale Mother’s Pride, and I remember feeling so happy as the mallards and tufted ducks hurried over to partake of our offerings. I was always less happy to see the Canada geese, with their hard serrated beaks and habit of hissing, and the swans were always very daunting when they waddled out of the water, as I seem to remember them  being bigger than me at the time. But I always felt that, by sharing our food with the animals, we were somehow helping them. We were a very poor family, and so we never had much to give them, but at least we were sharing what we had.

Sadly, life doesn’t seem to be quite as simple these days. A friend of mine pointed out that there are signs in Hampstead Heath alongside the lakes, asking people not to feed the waterfowl. I am pretty sure that you are also not allowed to do this at Walthamstow Wetlands. And there are many clear reasons not to through the sourdough into the nearest pond, as the Wildfowl and Wetlands Trust points out on their website. However, the issue is not so much feeding the ducks, as the kinds of things that we feed them.

The general message seems to be that bread is fine for ducks, so long as it’s in moderation, and herein lies the rub. During lockdown many people visited their local parks and ponds and became very fond of feeding the birds, so there were much higher volumes of visitors than usual, and most of them were feeding bread. Sadly, it seems that birds can get ‘hooked’ on bread, but if that’s all they eat they lose muscle mass and may be reluctant to forage for their natural foods, such as waterweeds and small invertebrates. It’s like being fed a diet of cake and then being asked to go back to salad – it might be good for us but it’s a bit of a wrench.

Protein inbalance and excess fat can also cause the Angel Wing syndrome in ducks and geese, so bread is implicated here too.

Plus, if there is a lot of feeding of bread an unnaturally high population of waterfowl can survive, which puts them at risk if, for example, a waterside cafe closes, or if people no longer visit (as I imagine has happened a lot as people drift back to work after lockdown). Excess numbers of birds can cause mess from their faeces, and uneaten food can attract rats and create the conditions for algal blooms.

So, what should we be feeding the ducks? The WWT recommends chopped or ripped up green vegetables, wheat grain and specialist foods, while the Canals and Rivers Trust suggests sweetcorn, frozen peas, oats, seeds and cooked or uncooked rice. I can’t help thinking that some of these foods would be a bit expensive for the average family, but lots of people have rice or oats knocking about. And it’s a shame that you can’t buy food for ducks when you buy your coffee at some of these places – it would be a great way to encourage people to feed something more healthy.

So, on balance we need to ease up on the bread, but I do think that for most people, especially children, feeding the ducks is a great way to get close to nature, and to start to be curious about the natural world. If we are a little bit more informed and mindful about our relationships with animals, everyone will benefit.

At Camley Street Natural Park

Dear Readers, you might remember that I made an autumn visit to Camley Street Natural Park in Kings Cross not long after it opened, and that I was very impressed by the tranquillity of the site. I was a little worried that, on a beautiful spring day, it would be extremely busy but it manages to retain its serenity even when there are more people about. We had a coffee and watched the coots chasing one another up and down the canal for a bit – they use their huge feet like little outboard motors. I was much struck by this graffiti too. Is Egg a human, or is this simply a declaration of culinary appreciation?

Then it’s off for a meander around the meadows and ponds. The reserve is adjacent to Coaldrops Yard which is now a very fancy shopping mall, but previously this whole area would have been used for loading and unloading coal, brought down from the Midlands by train and barge, and used to create town gas, which would have been stored in the gas holders in the first photo. The site was derelict by the 1970s, but was acquired as a nature reserve by Camden Council in 1985. This is its second incarnation as a reserve, and very nice it is too.

The meadow/bog area features all kinds of plants – green alkanet (which I am quickly coming to think of as the London Weed, it seems to be everywhere, three-cornered garlic with its triangular stems,  teasel for the goldfinches, and some red deadnettle for the bumblebees.

Green alkanet (and some sedum/hylotelephium with its brown heads to the left of the photo)

Three-cornered garlic

Red dead-nettle

Teasel

There was also a herd of wheelbarrows, just waiting for some volunteers who want to do some weeding or pond clearance.

There is cow parsley and alexanders: cow parsley is the earliest of the umbellifers to flower around here, and alexanders is becoming more common, I would say.

 

Cow parsley

Alexanders

There are some bluebells too, hybrid I’d say but pretty nonetheless.

Then it’s along to the pond proper – I rather liked this view of the tree trunks reflected in the water.

There are a few moorhens around, disappearing shyly into the reeds. I have heard tell of some reed buntings too, but didn’t see any today, though I did hear the call of a chiffchaff. I love wandering along the paths through the woodland, and they have some willow fencing, so they don’t have the same problem with trampling that some sites do. Plus, they have a London Wildlife Trust volunteer on site who patrols the paths to answer questions and make sure that people aren’t careering through the undergrowth.

There is some early hawthorn blossom….

And the wayfaring tree (Viburnum lantana) is in flower – it occurs to me that I have never done a Wednesday Weed on this plant, so watch this space!

And so it was a very pleasant meander around Camley Street. It is, of course, busier at the weekend, so there was no heron this time, but wrens and long-tailed tits buzzed through the branches. It feels like a real oasis in this bustling area, which is still full of cranes and builders and general development. If you are in need of a nice coffee and a chance to reconnect, or if you have business in this part of the world, I recommend a visit here to recharge your batteries, and to see how even a very small area can punch above its weight in terms of biodiversity.

 

Sunday Quiz – North London Plants

Dear Readers, you might think that North London would be a poor place for plants, but not a bit of it – there are a wide range of habitats, and a considerable number of ‘aliens’ who have made the pavements of East Finchley their home. Some might call them ‘weeds’, but for me they a valuable reminder of the extraordinary resilience and adaptability of life.

So, for this week’s quiz, see if you can identify the plants in the photographs below. I am going to make it a tad harder by not making it multiple choice this week, which is fiendish I know, but you’re all doing far too well. However, I will give you a little clue under each photo. So, ‘all’ you have to do is to name the plants.

You have until 5 p.m. UK time on Friday 15th April to pop your answers into the comments (as usual I will disappear them as soon as I see them) and the results will be published on Saturday  16th April.

Have fun!

1). Smelly but pretty?

2) The only native member of the cucumber family.

3. St Simeon’s Herb

4. Its leaves are so soft that some people call it the Andrex plant.

5) Also known as ‘moneywort’ and ‘herb twopence’.

6) The foodplant of the Wood White butterfly

7) Used to flavour beer and wine, and to sweeten the beds of our ancestors

8) Lemon-flavoured

9) Popular with birds, but beware of the cyanide….

10)This native might sound Scandinavian, but it’s the salt that it likes….. (we’re after the white plant, not the pink one :-))

The Day the Asteroid Struck….

Images of fish, thought to be victims of the asteroid strike that wiped out the dinosaurs (Robert dePalma, University of Kansas, via New Scientist)

Dear Readers, as I was innocently sitting at my desk writing yesterday’s blogpost, there was an enormous flash in the street outside, followed by an ear-splitting boom. I thought for a moment that an electricity substation had blown up, or something more sinister had happened, but as it turned out, it was just a thunderstorm directly overhead. However, for the plants and animals going about their lives 66 million years ago, the end of the world really was nigh, and, remarkably, scientists have found a site which preserves the remains of animals in the very immediate aftermath of the disaster.

The Tanis site in North Dakota was the site of a massive flood in the immediate aftermath of  the asteroid impact, which took place at Chicxulub on the Yucatan peninsula in Mexico. It’s unusual to able to date a site so accurately, but the impact was so severe that it produced glass crystals called tektites, which rained down in the days and weeks following the event. The fish that are found at the Tanis site have these tektites in their gills, which indicates that they must have died very shortly after the asteroid hit. The chemical signature of the tektites matches that on the impact site in Mexico, and the rock formation that they are preserved in is also characteristic of the aftermath of the explosion.

The site has been somewhat controversial – the original results, in 2019, were published in New Yorker magazine rather than in a scientific journal. However, a continuous stream of interesting fossils has been discovered, including, in 2021, the remains of a turtle impaled on a branch. The animal was probably about five years old, and had already escaped being eaten by a crocodile, judging by the bite marks on its shell. The lead scientist, Robert dePalma, explained the fossil in New Scientist in 2021:

“First, it would have experienced an odd seismic jolt, some minutes after the impact,” DePalma told the conference. “And then it would have seen tiny, red-hot glass beads [in the sky] as the ejecta would have started to come in from the Chicxulub site. Then, the surge rushed up, about 10.5 metres in depth. At that point, he or she got impaled by a branch. So it was a very bad day for the turtle.”

And today, The Guardian reports that the thigh bone of a small dinosaur, a Thescelosaurus neglectus has been found, perfectly preserved (even the skin can be seen), with fragments of debris from the explosion embedded in the bone.

It is astonishing to think that there is a site that preserves the remains of animals actually killed during the aftermath of the asteroid strike, and the BBC think so too, as they are in the process of making a documentary about the site (featuring David Attenborough no less), so UK viewers keep your eyes skinned – it will be called ‘Dinosaurs – The Final Day’. I suspect that the Tanis site will continue to produce fascinating details of this extraordinary day in the history of life on this planet. And although it was a bad day for the poor dinosaurs, it also cleared the way for the rise of mammals and for those other dinosaurs, the birds. It makes me think about how resilient life is, and how, pragmatically, nature seems to take lemons and make lemonade with them. Which, strangely enough, I find rather comforting.

At The Royal Academy – Man and Beast: Francis Bacon

Study for Chimpanzee (1957)

Dear Readers, as you might remember I am ploughing through a biography of Lucian Freud at the moment, and he was great pals with Francis Bacon. I find many similarities between their work – an obsession with the colour and texture of flesh, an insistence on what is actually there, a sense that ‘prettification’ is anathema. No one ever goes to see Francis Bacon to be cheered up, because although the word ‘visceral’ is overused, that’s what it is – these paintings go straight past the rational mind to something underneath.

As I stroll through the galleries of the Royal Academy (and to be out and about and doing something cultural is such a treat), I am struck by how many people look either bamboozled or disgusted, and I suspect that Bacon has been eliciting these emotions since he first started painting. Bacon was raised on a stud farm in Ireland, and was always fascinated by animals, though to my knowledge he never actually painted a horse. Still, he would have witnessed the raw emotions of ‘beasts’ at first hand, their lust and their violence, and also their deaths. He had well-thumbed copies of Muybridge’s books on animals and people in motion in his studio, and some of his paintings combine the human and the animal until they are the same.

In the Portrait of George Dyer (below), the human figure seems to be crouched in some kind of enclosure, like a zoo animal. Bacon’s subjects are often alone and confined. The reproduction doesn’t show it very clearly, but the ‘cloth’ to the right of the ‘enclosure’ was the same colour and texture as raw meat. The figure seems to be horned, or to have the mandibles of a beetle. He crouches as if uncertain what to do next.

Dyer was Bacon’s lover. They met in 1963, when Dyer was a handsome small-time gangster. Their relationship was sadomasochistic, alcohol-fuelled and deeply dysfunctional, particularly for Dyer, who discovered that being a muse, and a kept man, was not an easy life, regardless of how it appeared from the outside. He died of a deliberate overdose in 1971, two days before Bacon had a huge retrospective show in Paris.

Portrait of George Dyer Crouching, 1966

Bacon is, perhaps, the painter who most articulates sheer dread. His figures are always distorted, his mouths always screaming. The painting below predates Bacon’s ‘Screaming Popes’ series by several years, but already there’s the sense of existential horror – the figure encased and isolated in a glass cube. Is this about the loss of faith, the total loss of meaning? As usual with Bacon, it’s impossible to pin him down – the face is said to have been influenced by Eisenstein’s screaming woman from the film ‘Battleship Potemkin’, but the images are also based on Velasquez’s studies of Pope Innocent X.

Head VI (1949)

Towards the end of his life, Bacon was pushing the human figure about as far as it could go. He was working in the triptych form, and in 1988 he reworked his 1944 painting ‘Three Studies for Figures at the Base of a Crucifixion’, changing the background colour from orange to red, and making the figures smaller. The figures in both paintings are based on the Furies, who hunted down those who had committed matricide and patricide. One line from Aeschylus was said to have haunted Bacon throughout his life – “the reek of human blood smiles out at me”. When mouths are not screaming, they are looking to take a chunk out of someone.

Three Studies for Figures at the Base of a Crucifixion (1944)

Study for Three Figures at the Base of a Crucifixion (1988)

But strangely, after all that sound and fury, Bacon’s last painting is a subdued work. He had been fascinated by bullfights, with their combination of blood, cruelty, passion and death. But this image, with its muted tones and static subject, seems like a farewell to me: among the materials used in its creation is dust (and not for the first time – Bacon was notoriously slovenly in spite of his acute asthma, and would often use dust to create the colours and texture that his paintings needed).

“The world is just a dung heap,” Bacon told Joshua Gilder in 1980, when he was seventy-one. “It’s made up of compost of the millions and millions who have died and are blowing about. The dead are blowing in your nostrils every hour, every second you breathe in. It’s a macabre way of putting it, perhaps; but anything that’s at all accurate about life is always macabre. After all, you’re born, you die.” (Cabinet Magazine, Issue 35)

Bacon is undoubtedly one of the great painters of the twentieth century, with his unique vision. There is a truth to his work that it’s hard to deny. It’s not the only truth, however. There is no room in his work for beauty, and precious little for love. I can admire him without wanting to live in his world.

Francis Bacon: Man and Beast is at the Royal Academy until 17th April, so get your skates on if you want to visit!

Study of a Bull, 1991

April Garden Update

Dear Readers, spring has certainly sprung here in East Finchley, so I thought I’d give you a quick guided tour during my lunch break. The flowering currant is splendid as always, and much appreciated by the hairy-footed flower bees and this little blurred ginger blob, who, if I’m not mistaken, is a common carder bee. These small bumbles seem to emerge very early, and to stay around for longer than anybody else, and very sweet they are too.

I love the flowering currant; if it wasn’t for the fact that I need some later flowering plants, I would be collecting them! This one is the self-sown child of the one below, which has much redder flowers, but which is no longer so vigorous as it once was.

I planted lots of grape hyacinths last year, and while the ‘ordinary’ deep blue ones have been up for a while, the pure white ones are just getting going…

I also planted some which were blue at the bottom and white at the top, and they are just beginning to show. I suspect that like many varietals they won’t be as tough and floriferous as their less fancy cousins, but let’s see.

 

The wood anemones have come back, though I fear our sluggy friends might have been nibbling at the petals.

The Geranium macorrhizum turned out to be a very good buy, it’s been in flower for a couple of weeks now.

And the forget-me-nots are doing well…

As are the fritillaries. What you see beside them is a fancy new deadnettle, just in case you thought things were going completely to pot – I bought them last year and they didn’t flower, so fingers crossed for this year.

The marsh marigold is flowering…

And we are going to have a spectacular show of climbing hydrangea this year, just look at all the flowers…

I was just about to head back indoors when I heard the fluty song of a blackbird. Only it wasn’t, as a rapid-fire combination of whistles and clicks straight afterwards proved. No, it was this little chap. Enjoy your leisure time, starling, you’ll soon have lots of little beaks to feed….

Hot Ostriches!

Male ostrich (Struthio camelus) (Photo One)

Dear Readers, I don’t know what it is about birds, but much as I like them, they don’t always like me. As you may remember, I was chased by a goose when I visited a City Farm, and when I went for my first ever visit to South Africa, our jeep was hotly pursued by a male ostrich, which was a bit like being hunted down by a velociraptor. Gosh, those creatures can run! And they know all the short cuts! I remember our jeep bumping over potholes and careering through bushes. We’d stop, thinking we’d finally outrun Mr Ostrich, only to hear the telltale thumping of his feet as he accelerated towards us. As he was more than eight feet tall on his tippy-toes and had already given someone a nasty peck on the head, we were all semi-traumatised by the experience. For the rest of the trip, the sight of an irate hippo or a prowling lion didn’t bother us, but we’d all shriek at the sight of an ostrich. It feels a bit like the chicken’s revenge.

Anyhow, I was fascinated by this article in New Scientist this week, which is all about the neck of the ostrich. Large animals tend to have more problems with rapid temperature changes because they can’t lose heat quickly (if you all remember your surface area to volume from school biology lessons). Different creatures evolve different methods to deal with this, like the enormous flappy ears of the African elephant. For the ostrich, the key seems to be that their necks act as a radiator.

Herd of ostriches (Photo Two)

Erik Svensson, from Lund University, Sweden, spent five years taking infrared photographs of ostriches at a research farm in Klein Karoo, South Africa, and discovered that the ostrich’s neck acts as a ‘thermal window’, emitting heat when it’s too hot, and retaining it when it’s too cold, thus keeping the temperature of the head and brain stable. Our guide on our ostrich-embellished South Africa trip told us that the birds only have a brain the size of a walnut, and was very disparaging about them. However, as the ostrich had reduced a whole jeepload of English tourists to jabbering wrecks I think he might have underestimated them.

The research farm has three different subspecies of ostrich, one from Kenya, one from Zimbabwe and one from South Africa. Interestingly, the ones from Zimbabwe and South Africa, where there is more climatic variation, seem to be better at shifting the temperature of their necks. Furthermore, female ostriches who had a greater temperature difference between their necks and their heads laid more eggs in the following period than ostriches with a smaller difference, implying that the neck is a buffer for heat stress. After all, keeping our brains from frying is important for any species, hence the need for sunhats and for none of that ‘mad dogs and Englishman going out in the midday sun’ stuff.

Ostrich panting (Photo Three)

Ostriches also pant, and Ben Smits at Rhodes University in South Africa wonders if the hot blood from the neck is actually shunted upwards and then cooled when the animal opens its mouth, as happens with dogs (and humans).

Scientists speculate that as the climate gets warmer, the neck of the ostrich could get even longer – this appears to be a genetic adaptation, and so it can be passed on through the generations. It’s clearly beneficial for the ostrich, both in terms of survival and of reproductive success. I’m not sure exactly how I feel about an even taller ostrich than the one that we met, but maybe next time I’m planning visiting somewhere which has ostriches, I’ll take a tin hat (though that might just lead to my brain overheating).
