Pretty Pictures from Ainsdale

Today, I was back on the sand dunes at Ainsdale on the Sefton Coast; this time, I was joining in a wildlife photography walk, organised by the Gems in the Dunes team and led by local photographer Trevor Davenport. Trevor pointed out plenty of interesting insects and plants for us to photograph, providing advice like getting down to the level of your subject (hence why many nature photographers have dirty knees) and making sure to move distracting scenery, like long grass, out of the way. Here are some of the pics I took!

Easter Explorations

Over the Easter holidays in April, I took advantage of the lovely weather by visiting a couple of wildlife spots I’ve been to previously, to see what I could find this year. First, there was a nature reserve in Cumbria, where I ended up staying for four hours as I was having such a nice time.

There were common lizards everywhere, mostly on the boardwalk but some in the foliage as well: I must have seen at least 40 in all. Among the many birds around was a male reed bunting, singing loudly in a tree.

What I was really hoping to spot, however, was a snake. And when I did, it happened quite unexpectedly: my circuit had taken me back to the car park, I turned around, and a male adder was slithering across the road! He quickly disappeared into the foliage on the other side, but it gave me encouragement. I went looking back along the boardwalk, and sure enough, there was another male adder slithering among the dry leaves. It was a very productive day for wildlife watching.

A couple of days later, I went for a walk among the sand dunes in Lytham, where I had previously spotted more common lizards. I soon spotted one in the same area I had seen them before, though it was gone very quickly. As I walked, I regularly heard rustling sounds in the grass, but there was no way to know if it was lizards. Finally, I did see another lizard about half a mile away from the first; that one vanished in about two seconds, before I could photograph it. That’s the problem with sunny weather; it leaves reptiles well energised!

Herpetofauna Workers Meeting 2019

HWM Blog 2

Last weekend, I attended the 32nd Herpetofauna Workers Meeting, in Stoke-on-Trent: this conference, organised by ARG UK and Amphibian and Reptile Conservation, is to share information on the latest work in UK amphibian and reptile conservation. While I wasn’t able to attend the Saturday lectures, I did arrive in Stoke in time for the conference dinner on Saturday evening. This was a great opportunity to talk to other attendees: some people I already knew were there, including a party from Bangor University; but at the dinner and during the following day, I was able to make new acquaintances, talking to some very interesting and friendly conservationists.

The lectures covered a wide range of projects and focus species. These included conservation-based scientific studies: Dr Naomi Ewald talked about PondNet’s study monitoring the presence of great crested newts by detecting their environmental DNA (eDNA); while Dr Silviu Petrovan talked about evidence-based conservation, measuring how successfully amphibians use tunnels built under roads. I was also particularly interested in Sophia Ratcliffe’s lecture on using data compiled from the NBN Atlas to examine long-term reptile population trends, and Louise Sherwell and Mariya Tarnavska’s project on using ladders to help amphibians escape from gully pots on kerbsides.

There were also a couple of Q&A panels: I attended one that covered general herpetological conservation questions. The panelists gave their opinions and knowledge on whether restrictions on animal trade can help prevent the spread of disease, whether Brexit could be an opportunity to strengthen conservation legislation, and what can be done regarding the decline of native species (public outreach and monitoring local sites were encouraged).

Thank you to ARG UK and Amphibian and Reptile Conservation for organising this event – I’m already looking forward to the next one!

Gems in the Dunes

Today, I went down to Ainsdale – close to where I’ve done some habitat management volunteer work in the past – to do some volunteering for the Gems in the Dunes project. This project, led by Amphibian & Reptile Conservation, aims to preserve the sand dune habitat on the Sefton Coast, home to several species which are rare in the UK, such as natterjack toads, sand lizards and northern dune tiger beetles.

This habitat is threatened by a variety of factors, not least encroachment by humans. The problem that the other volunteers and I were addressing today was the overgrowth of sea buckthorn on the site. Native to the east coast of the UK, sea buckthorn becomes invasive when introduced elsewhere; thickets of it spread over the dunes, reducing the open marram grass habitat that the local wildlife needs to bask and thrive. Since much of that wildlife is inactive during the winter months, we could carry out the work while causing minimal disturbance.

The volunteers attacked the buckthorn with loppers and saws, burning the cuttings on a bonfire; any stumps were treated with glyphosate so that they wouldn’t grow back. Much of the last hour was then spent carrying buckets of water back and forth to make sure that the bonfire was completely put out! The weather was mild – through a combination of working and being close to the fire, you warmed up very quickly – and the manual work felt very satisfying, particularly as we made such an impact on that particular patch.

A Starling Murmuration at Brockholes!

Blog 1

Brockholes Nature Reserve, located just outside Preston and right next to the River Ribble, was built on the site of a quarry and opened in 2011. It is a good spot for birdwatchers, featuring both woodland and lake habitat; you might even spot a roe deer if you’re lucky. When I went down there yesterday afternoon, the usual birds were about: swans and a grey heron on the Meadow Lake, great tits on the bird tables, a robin keeping its head down in the reeds. There were also some wooden sculptures of characters from The Wind in the Willows, which had been added since my last visit. My main aim for going that day, however, was the hope of seeing a starling murmuration.

Well publicised on TV, starling murmurations have become one of the UK’s best known wildlife spectacles. During the winter months, the UK population of starlings increases as birds migrate here from colder parts of Europe. At dusk, thousands of starlings come together at their communal roost sites, forming huge flocks that offer safety in numbers against predators. Such spectacles create the impression that starlings are not a conservation priority, but in fact the UK population is estimated to have fallen by four-fifths since the late 1970s, possibly due to farming practices reducing the availability of the invertebrates they eat.

As the daylight began to fade, I chose a spot looking over a large lake called the Number One Pit. Behind me, across the road, I also had a view of Brockholes’s floating Visitor Village on the Meadow Lake, just in case the starlings decided to turn up there. Of course, seeing a large flock displaying in the sky was not guaranteed. But at 3:20pm, a small group of starlings suddenly appeared over the Pit, closely followed by another. As they began converging, I experienced the thrill that wildlife-watchers get when they realise today is going to be a lucky day.

The murmuration grew very quickly, hovering over the woodland on the far side of the lake. Its visibility fluctuated, the starlings becoming less obvious against the overcast sky whenever they dispersed a little. At first, they formed a long, serpentine pattern that stretched across to the M6 motorway; but as more starlings arrived, the murmuration converged into a more visible ball. The most interesting patterns formed when another bird, possibly a crow, made an approach: the murmuration fluctuated, bulged on either side and split in two, with one sub-flock quickly moving to catch up with the other. The display went on for a good long while: at one point, I thought it was over when the starlings suddenly ducked below the trees, but it must have been a response to another disturbance because they soon rose again. Finally, with the sky getting murkier, the flock began shrinking, skimming the trees with fewer starlings coming back up each time. Then, at around 3:55, the last of them ducked down, and nothing more was to be seen. It had been a cracker, all right.

Venom Day 2018

This December, Bangor University hosted its ninth Venom Day conference, in which researchers get together to talk about the most recent studies of venomous and poisonous animals.

As I studied for my own degree in Bangor, Venom Day provides a great annual opportunity to go back to a city I love, meet old friends, make new ones, and listen to some fascinating lectures! There are plenty of opportunities to socialise and network, both before and during the event; many of the attendees got together for a light-hearted quiz the night before. I was also able to get a copy of Mark O’Shea’s new book, The Book of Snakes, which features descriptions and photos of six hundred species of snake, almost one in six of all the currently recognised species in the world!


There were multiple lectures on the skin secretions of frogs, which are being utilised in both the development of new antibiotics and the treatment of diabetes. Kim Roelants gave an interesting talk on how anti-microbial peptides (AMPs) help to defend a frog from predators, by faciliating the absorption of the frog’s defensive toxins when the predator makes contact.


Other talks I particularly liked included:

  • Wolfgang Wuster’s talk on venom variation in the Mohave rattlesnake (Crotalus scutulatus) and efforts to determine whether this variation is primarily determined by diet, climate, or random genetic divergence between populations.
  • Ronald Jenner’s talk on differing venom composition in the five different lineages of centipede; he opened his lecture with some examples of centipede bites on humans and other animals, including a video of a man suffering a very painful bite from a Scolopendra heros.
  • Matt Gardiner’s talk on the slow loris (Nycticebus spp.), the world’s only venomous primate, which has also been talked about on previous Venom Days; this particular study regarded a survey of research and rescue centre staff who had been bitten by slow lorises, and the symptoms they experienced.
  • Nicholas Casewell’s talk on studying another venomous mammal, the Hispaniolan solenodon (Solenodon paradoxus) – little is known about the venom of this animal, so this study aimed to determine its composition and likely function.
  • Jasmine Headlam’s talk on the testing of different jellyfish sting treatments, specifically lion’s mane and Portuguese man of war, which can both be found in British waters. The conclusion was that vinegar and a hot pack are most effective.


Towards the end of the day, there were lectures on addressing the problem of snakebite in India. Anatoli Togridou, who works with Ben Owens and Vishal Santra (whom I volunteered with in Himachal Pradesh earlier this year), gave her lecture on taking a preventative approach to snakebite. She described ongoing efforts to educate the local communities of Himachal Pradesh on how to avoid snakebites and what to do if the worst happens. This has involved determining their existing knowledge of different aspects of the issue (e.g. how to access appropriate treatment, how to recognise venomous snakes); one of the recommendations is increased engagement with traditional healers, who are often the first people that a snakebite patient will turn to.

Meanwhile, Shaleen Attre talked about the efforts of the Indian Snakebite Initiative, which has not only made progress in educating Indian communities on snakes, but has established a national-level network, mapped records of both dangerous snakes and hospitals with antivenom, and helped to minimise snakebites among those who were affected by the floods in Kerala this summer.

It was another excellent Venom Day overall – thank you to everybody who organised it, as well as of all of the speakers!


Of Sirens and Ichthyosaurs

There have been some very interesting studies published this week regarding aquatic creatures: a living amphibian, and an extinct reptile, both very peculiar in their own way.

First, a new species of salamander has been described from a very bizarre and little-known family called the Sirenidae. The sirens are aquatic salamanders, known for possessing serpentine bodies, reduced forelimbs, no hindlimbs at all, and external gills even in their adult stage, like axolotls. Before this study, only four living species of siren were recognised, limited to the southern United States and northern Mexico. However, a type of siren found in wetland habitat in Alabama and Florida has been determined to be distinct from any currently recognised species. Nicknamed the “leopard eel” due to its distinctive spotted pattern, it has been given the scientific name Siren reticulata. Not only is it one of the largest amphibians alive today – with the biggest of the known specimens being over two feet long from nose to tail – but it is one of the largest new species of animal to be described in the United States in the past century!

Second, a fossil of an ichthyosaur – fish-like marine reptiles which lived at the same time as the dinosaurs – has been described which is so well preserved that it actually features the remains of soft tissues. The animal, which is named Stenopterygius and swam over what is now Germany about 180 million years ago, exhibits traces of pigment cells which indicate it was countershaded – darker on top and lighter on the belly. This colour pattern, found in many living marine vertebrates such as sharks, helps in camouflaging a sea-going animal, whether viewing it from above against darker water, or from below against the surface light.

Not only that, but Stenopterygius also possessed a layer of fatty blubber, like modern whales and seals, but unlike any living reptile with the exception of the leatherback turtleStenopterygius‘s blubber would have served as an insulator, allowing it to maintain a body temperature higher than its surroundings, as the leatherback turtle can – again, this sets them apart from most other reptiles, whose body temperature is dependent upon the environment. I love it when we discover new details like this that expand our image of extinct animals.
