Signs of the times: Autumn #13


More comparisons between the British countryside of today and that from 1959-1961 in the paintings of Charles Tunnicliffe in the Ladybird "What to look for..." series of books.

"Then the sudden rush
Of the rain, and the riot
Of the shrieking, tearing gale
Breaks loose in the night,
With a fusillade of hail!
Hear the forest fight,
With its tossing arms that crack and clash
In the thunder's cannonade,
While the lightning's forked flash
Brings the old hero-trees to the ground with a crash!
Hear the breakers' deepening roar,
Driven like a herd of cattle
In the wild stampede of battle,
Trampling, trampling, trampling, to overwhelm the shore!"

Henry Van Dyke (from: "Storm-Music")

Autumn Picture 13


Well, when I started this set of blog posts on these Ladybird books, I had rather hoped to be able to keep pace with the four seasons as I progressed through the four books, starting with Spring. Clearly, although I managed this for Spring and largely for the Summer book, the timetable went out of the window when I was busy in the Autumn. So, here we are, in June and I’m writing about Autumn. Never mind, I hope you are still enjoying these posts regardless of what it looks like outside your window. I will be satisfied if I finish the series in the 50 year time window since the books were published, which was 2009-2011. That means I have the rest of the year to finish the second half of the autumn book and the Winter volume. On, on...


Here’s a wild picture. Until last month’s unprecedented extreme weather conditions in Scotland, I would have said it seems a bit odd to be writing about wild Autumn weather in June but hey ho... Here, a herd of young cows are sheltering behind a high hedge from a gale and lashing rain. Some starlings and magpies are sheltering as best they can behind the cattle. Growing under a fallen, broken tree, there are some puffballs. The only part of this scene that you couldn’t have found here last week was the puffballs – it’s a bit early for those in June! But hey, this is supposed to be a picture from Autumn. In fact, as far as the theme of these posts goes, comparing our natural history today with that displayed in paintings from 50 years ago, I don’t have much to say for this one. I’ve already covered starlings here and magpies here and, as I’ve said elsewhere in these Autumn posts, we actually don’t have good information on the changes in the distribution of many of our native fungi over time, even the relatively large ones like puffballs.

Having lived in the Stirling area for 22 years, I’ve seen many little puffballs around here, but never a giant puffball, the edible (in fact, gourmet) giant puffball beloved of gourmands, and delicious when sliced and fried; until last Autumn that is, when O and I were walking near Dunblane and found the shattered and largely decomposed remains of a giant puffball, but which was still capable of producing clouds of spores. So we took some pieces and scattered them along the edge of the field we found it in and, from late summer, we will start checking for signs of growth, just in case!

Signs of the Times: Spring #11

More comparisons between the British countryside of today and that from 1959-1961 in the paintings of Charles Tunnicliffe in the Ladybird "What to look for..." series of books.



"Come, fill the Cup, and in the Fire of Spring
The Winter Garment of Repentance fling:
The Bird of Time has but a little way
To fly--and Lo! the Bird is on the Wing."

Spring picture 12 is a simple tableau showing two magpies sitting in the branches of a larch tree, with the branch of an ash tree appearing from below. Magpies (Latin name: Pica pica) belong to the crow or corvid family and, like other members of that group, are still often persecuted (i.e. killed by shooting, or trapping then shooting) because their mode of living involves the eating of small birds, their eggs and nestlings. The text in the Ladybird book suggests that magpies also eat the eggs of birds bred for game, such as pheasants and partridges and goes on to make a highly judgmental comment about “countrymen” being justified in feeling that they have done a good deed in shooting a magpie as “it is certain that any magpie shot in April will have the egg-yolk of some other bird’s egg on its bill”. It is probably a sign of the times in which this book was originally written that the respected ecologist who provided the text for the book could profess such a belief in a children’s book, i.e. magpies were egg-eating vermin that it was desirable to shoot, as opposed to being a native element of our bird fauna, with an ecological niche of its own which is, presumably, how most ecologists today would regard this species.

Magpies are still trapped and killed today by the game management sector. It is a truly handsome bird that, as well as eating eggs, etc, also feeds heavily on insects, seeds and carrion. Like most crow species, a highly adaptable species, magpies have successfully invaded our urban and suburban world in recent decades. The occasional urban guerrilla nutcase anti magpie vigilante citizen makes a splash in the papers, with claims about outrageous numbers of magpies that they have trapped and killed. As if a beautiful small garden bird has any more intrinsic value and right to life than a beautiful black and white magpie with its iridescent blue and green wing and tail plumage. In ecological terms, magpies in gardens taking eggs and chicks are part of what the media likes to call “the natural order”. Almost all the individual organisms ever born die as eggs or young, sometimes eaten, sometimes killed by their siblings, sometimes killed by parasites, or by an unkind environment. Without predators, we’d be knee deep in everything else and natural selection would be missing a key mechanism.


The British Trust for Ornithology reports that “the remarkable adaptability of Magpies has enabled them to colonise many new urban and suburban localities since the 1960s. Magpies increased steadily until the late 1980s, when abundance stabilised”, as you can see from the following graph:






There has been a minor decrease in the magpie population of the UK during the last five years. The Game and Wildlife Conservation Trust suggests that, since 1990, the widespread adoption of the Larsen trap for predator control may have been responsible for a large increase in Magpie numbers killed on shooting estates, Possibly it is this that has now driven the population back into decline. It is possible that a warming climate is responsible for the strong trend towards earlier egg laying by magpies in the mid 1960’s:




The Larch (Latin name: Larix decidua) is an unusual thing in Britain – a deciduous conifer, or cone bearing tree that loses its needle in Autumn. It isn’t a native species in Britain, and there are two different records for when it was introduced first – the New Atlas of the British and Irish Flora says it was in 1862 for timber, and first recorded in the wild in 1886. In his book Flora Britannica, Richard Mabey says it was in 1620 and that larch was the species planted for the first forestry plantation in Britain, on the Duke of Atholl’s Perthshire estates in the mid-18th Century. Although the New Atlas of the British and Irish Flora says that there are more larch records now than in the original 1962 Atlas, it was greatly under-recorded in 1962. It is still planted a little for timber nowadays but its susceptibility to a disease, larch canker, means that other species are generally planted in preference. It is pretty widely distributed in Britain, as it naturalises in the wild easily from larch plantations. A light green in the Spring (see the picture!), larch needles go a beautiful golden colour in Autumn before they are dropped. In advance of this blog post, I have been keeping a daily eye on my nearest larch tree in the local park and it produced needles a couple of weeks ago and I saw the little pinky-purple flowers on it a week or so ago.

The other tree featured here, with its grey smooth bark, large black buds and blueish flowers, is the Ash (Latin name: Fraxinus excelsior) a common tree species found native over all of Britain and Ireland except for some more remote and upland parts of northern Scotland, the Outer Hebrides and the Northern Isles. The New Atlas records its distribution as stable compared with 1962.

The Ash is a tree with a mythological heritage. In Norse mythology, Yggdrasil, the “tree of life” was an ash tree. I wonder whether it is a cultural memory of this, following all the Norse settlement in parts of Britain, that led to the ash being regarded in folklore as a healing tree, or a tree with magical properties. Richard Mabey provides a great account in Flora Britannica of the cultural importance of the ash in Britain and all the many uses to which it has been traditionally put, not least the many ways in which children in less televisually and game console demanding times used ash sticks and branches in games.
