A Swift Return to Summer

By Chris Jarvis, Education Officer

Amidst reports during the last week of Swifts being sighted feeding over the nearby Farmoor reservoir, Museum staff have kept their eyes to the skies eagerly waiting to be the first to spot our resident birds returning to their breeding site in the nest boxes of our tower. A wet and windy weekend caused by a deep depression over Britain meant little opportunity to feed on their diet of small flies and other invertebrates that make up the aerial plankton they relish, and which normally drifts unseen above our heads in large numbers on still summer days.  The high winds would certainly also have made any attempt to land, for the first time in a whole year since they left their nest boxes and for the first time ever for those just reaching maturity, extremely precarious, and so it seems our Swifts headed farther afield, possibly back to continental Europe, for a few days to await better conditions.

However, this morning, the 5th of May and right on cue, we were treated to the first two Swifts performing a low, high speed fly-by of the tower. Having flown around 14,000 miles in the last year from the Museum’s tower to their winter feeding grounds in southern Africa and back again, the Swifts have arrived on exactly the day of their average time of arrival over the last couple of decades.  We know this because the Swifts in the tower are part of an ongoing study which is the longest running study of any bird colony in the world, started by David Lack in 1947, our Keeper of the Swifts, George Candelin still climbs the spiral stone stairs and ladders each week under red lights to carefully and quietly monitor each nest box throughout the breeding season an count and ring each chick noting down all sorts of other data as he does so from wind speeds to egg rejections, weights and even altercations between birds in boxes over rights to nest sites.  Whilst you can’t be involved in the weighing and ringing of the birds, we do offer the next best way of getting involved; our nest box webcams, which you can find on our ‘Swifts in the Tower’ page, allow you to watch all the action live as it happens from the arrival of the adults to the final fledging as the next generation takes wing for the first time. Hidden microphones will also allow you to hear as screaming parties bang their wings against the nest box covers in order to ascertain if they are occupied and the keening noises of begging chicks!  George’s stats and comments will also be downloaded to the Swift’s Diary each week enabling you to get a full picture of what’s happening across the colony’s 147 nest boxes as the season progresses.

Swifts have markedly declined in numbers over the last few decades, and their breeding season is one of the few times anyone has to measure population changes and you can get involved, too.  Check out if there is a Swift City project near you like Oxford Swift City @oxford_swift or @EdinburghSwifts to get directly involved in monitoring projects or just record your Swift sightings to the RSPB at their Swift Mapper site. All your observations give us a really good idea of how these enigmatic summer visitors are doing!

Update-in the half hour it has taken to write this blog post: the number of Swift’s flying around the tower is up to 5-and they’re screaming!

Summer is here!

Hedgehog Awareness Week

For Hedgehog Awareness Week, Zoology Collections Manager Mark Carnall and Museum Librarian and Archivist Danielle Czerkaszyn discuss these prickly and charming creatures.

The 2-8 May is Hedgehog Awareness Week, which give us an excuse, not that one were needed, to talk about these charismatic mammals. Although the West European hedgehog (or common hedgehog if you’re in Europe, these vernacular names get very confusing when geography and language is taken into account), Erinaceus europaeus, is probably the hedgehog that springs to mind to many of our readers, there are nearly twenty living species of hedgehog and many fossil species are known.

In terms of evolutionary relationships they share a family with the moonrat and the rather wonderful gynmures, distinctly un-hedgehog-like relatives.

Their characteristic spikes that run across the back of hedgehogs are modified hairs which are periodically replaced and each individual hedgehog has around 7000 spines at any one time, varying slightly with age and size. Behaviourally, they are competent climbers (and have a built in shock-absorbing coat should they fall) and surprisingly perhaps, all species are thought to be competent swimmers.

Although much loved across their native range, Erinaceus europaeus, is considered a pest species in New Zealand where it was deliberately introduced as a form of biological control, by acclimatisation societies and possible as pet animals. They have now spread to all but the highest parts of New Zealand threatening native species of birds, amphibians, reptiles and directly competing with native mammal species.

In 2020, Erinaceus europaeus was added to the Red List for British Mammals as vulnerable across the lists for Great Britain, England, Scotland and Wales informed by analysis of citizen science data although there remains some uncertainty about true population levels.

Unsurprisingly perhaps they are comparatively well represented in the collections at the Museum including specimens donated and prepared for the Museum from the 19th Century through to much more recent specimens acquired from road death animals for display. The specimen pictured above being one such relatively recent acquisition for display in the Museum’s display case on the animals featured in Alice in Wonderland.

We’ll leave you with one more hedgehog from the Museum’s library and archives. Hedgehogs unusual appearance initially led to some odd beliefs about why their quills existed. For example, in his book ‘The History of Four-Footed Beasts and Serpents’ (1658) Edward Topsell wrote:

“The hedgehog’s meat is apple, worms and grapes: when he findeth them upon the earth, he rolleth on them until he hath fylled up all his prickles, and then carrieth them home to his den.”

– Edward Topsell

One of the most common questions about hedgehogs is how do they mate? The answer is of course, very carefully.

Worms, fish and … Greenland? Hugely different topics which all have one thing in common – the Museum’s First Animals exhibition online lecture series. Running every other Wednesday from May until September 2020, this series provided a fantastic insight into a wide range of topics about how the first animals lived, died, and are studied. And illustrator Rachel Simpson tells us how she drew her way through them all…

I came across this lecture series just before the first talk and I knew I had to sign up. Drawing along to lectures is a hobby I seem to have developed in the past few months as we went into lockdown and didn’t have much to do. It’s the perfect combination for me – an opportunity to listen to interesting topics and brush up on my live drawing skills at the same time. There’s no pause button, there’s no asking the webinar speaker to just go back a few slides and hold on a minute whilst I draw; it’s fast paced, it’s inspiring and it’s a great way to just create art.

Barma Booties used on the rocks at Mistaken Point, and my first drawing of the series.

I’ve done some illustration work with the Museum before so I knew that it was going to be fun. In 2018, I worked with Dr Jack Matthews illustrating Ediacaran Fossils as part of a collaborative university project between the University of Plymouth and the Museum. I was also lucky enough to be able to go to Newfoundland and see some of the fossils myself, again with Jack. This was such an incredible opportunity and opened up a whole new world of science/art collaborative work which I didn’t know about before.

The First Animals series kicked off with Jack’s talk titled Don’t walk on the rocks! – an interesting insight into how protective “Barma Booties” (some rather funky socks worn to protect fossil sites such as Mistaken Point, Newfoundland) might actually be damaging to the fossils they’re meant to be protecting. Having been to Mistaken Point myself and worn these socks, it was interesting to hear about their possible impact and to learn about the experiments conducted to prove this fact.

Of course, at the same time as Jack was talking, I was scribbling away in my sketchbook trying to form some sort of visual response to the talk. At the end of the hour I’d managed a portrait of Jack and a family of Barma-Booted tourists trampling on the fossil site. It was a start. The beginning of my lecture drawings and a point at which I can retrospectively say started a new hobby.

Annelid worms drawn with Tombow brush pens.

Over the following weeks we heard about worms from Dr Luke Parry; 3D reconstruction from Dr Imran Rahman; The Chronicles of Charnia by Dr Frankie Dunn; and the first animal skeletons from Dr Duncan Murdock. Luckily for me, all the speakers kindly included photos and descriptions of the topics they were discussing which meant that I was never short of visual inspiration for my drawings. After all, it’s hard to try and draw an annelid worm if you’ve never seen one before.

I love to look at the fossils being discussed and then try to draw a little character or creature inspired by them. They’re not scientifically accurate, nor are they always anatomically correct, but they have character and begin to bring to life the essence of something that’s been dead for many millennia. The fossils are obviously stone-coloured so I take as many liberties as possible when it comes to colour. I like to make them as vibrant and colourful as I can, so although they probably didn’t look like that, that’s how I like to think they looked.

Within my wider practice I like to use stamps as the basis of my illustrations. These however, are time consuming to make and therefore not very suitable for when I’m drawing along to lectures. As a result I’ve found myself using brush pens and pencils to make my lecture illustrations. If you’re interested in art, or thinking about getting into art, brush pens will be your best purchase. They create a wonderful quality of line and are quick and easy to use. Whereas a ballpoint pen will give you one line of a certain weight and thickness, brush pens are versatile and depending on the pressure applied, the line quality will change.

For the first few lectures I only used brush pens, but later on I decided to use coloured pencils as well, to add depth to the drawings. As I got more used to drawing in lectures I found that I was making more illustrations per talk. Early on, I managed to finish maybe a double page in my sketchbook but towards the end of the series I was filling four double pages! It’s amazing what a little bit of practice can do.

As the weeks went by the talks continued and we heard about the evolutionary origin of animals from Museum director Professor Paul Smith; an introduction to taphonomy, the study of fossilisation, by Professor Sarah Gabbott; and how the first animals moved by Professor Shuhai Xiao.

During this time I became a lot more confident drawing the specimens; looking back I can see that this was the period in which my work developed the most. My drawings began to have more character and life. The landscape drawings were slowly becoming more realistic and detailed. This was great news for me as this whole endeavour began as a way to practice my drawing skills in a timed environment.

Paul Smith’s lecture has to be my favourite of them all. He gave a wonderful talk all about the Evolutionary Origin of Animals and talked us through his fieldwork expedition to Greenland. How I would have loved to have been on that trip!

It was during Paul’s talk that I made one of my favourite drawings from the series – the plane – and coincidentally it was also at this point that I bought myself some new polychromo pencils. I started using these pencils in my illustrations on top of the Tombow brush pens. The pencils added a softer layer on top of the solid base colour from the brush pens and meant that I could add more details, shading and most importantly, the characterful eyes I love to add to my drawings.

Buoyed by this development in my drawings, and some lovely responses to my work on Instagram and Twitter, I raced through the next few weeks of talks and made twelve pages of drawings over the next four talks. Professor Derek Briggs told us all about extraordinary soft-bodied fossils; Professor Gabriela Mángano told us about the trace fossil record; and Professor Rachel Wood gave us her thoughts about what triggered the Cambrian Explosion.

Another of my favourite drawings from the series was from Derek Briggs talk about extraordinary soft-bodied fossils. Here, I made a small series of drawings based on some of the animals mentioned in the talk and as soon as I’d finished drawing them I wished that they were real and that I could pop them in a fish tank and keep them as pets. These drawings got the best response on social media too and it’s wonderful now to look back and compare these drawings to the work I was creating at the beginning of the series.

The First Animals series may be over but keep your Wednesday evenings free because there are more talks to come! The next series, “Visions of Nature”, starts on 8 October so make sure you join us then! A huge thank you to all the speakers, to Jack for hosting and to the Museum for running the events.
