Update

Llandegfedd:

A bitter-sweat visit to Llandegfedd, as wildlife sightings are commonly accompanied by wildlife disturbances.
Many firsts for the year, in the form of Large Red Damselflies, Fritillaries, Swallows, Redshank, Lapwing, Common Sandpiper and Little Ringed Plovers.

As you can hear in the recording below, the LRP’s are getting very frisky, song displaying and remarking their territories, but constant disturbance from Dogs and People make it impossible to settle, and eventually they’ll commit to one spot and take a chance, or they’ll simply try and nest somewhere else more suitable. Dog poo bags hanging on tree’s (in no-public access areas), BBQ’s on the ground in the wildflower meadows where there are Adder’s Tongue ferns and plenty of Orchids coming thru. To most people they are just fields but they are so much more. The signage that has been put out by DCWW is so conflicting, there needs to be clear, educational messages and fencing to prevent disturbance. We need to educate people otherwise this will never change. It’s not their fault, they don’t know any better. This is where a Wildlife Educational Officer is needed at Llandegfedd. They have the facilities, they just need to pay somebody with the passion to do it.

Birding

It’s a struggle to fit any ‘serious’ birding in, but a last minute journey to Goldcliff point with Craig Constance to do some sea watching, was well overdue, but came just at the right time as there as been some considerable numbers of Terns, Gulls and Waders migrating into a NE wind. Our count was pretty good for an evening visit, with 59 Comic (Common or Artic) Tern, 19 Bar-tailed Godwits, 1 Fulmar, 50+ Swallow, 9 House Martin, 20+ Sand Martin, Artic Skua (lifer) and the most eventful was the Little Tern(!) passing at just 30m, but that ended up being a total disaster! as I blasted off 30 shots, each appearing to hit the mark in the optical viewfinder, but I looked down with a smile on my face, to find that I had no memory card in camera!! Lol I just about got a card in as it disappeared away in the distance lol. I was happy to still get a record shot though as it was a new bird for me. Bean Goose and White-fronted Goose are still on the Lagoons where I suspect they will stay for a while as they don’t have any adults to follow back to their breeding grounds. Good numbers of Whimbrel flocking in at the

Sound Recording

Plenty of recordings to share, but here are my favourites. I’ve got quite the collection of mimicking bird species now but I’ve got to say, this Blackcap mimicking Mistle Thrush has got to be one of my favourites. Equally, the local Mistle Thrush has a fantastic Lapwing mimic, which I only managed to capture on my pre-record function but it’s on the todo list. Just take a listen to that Blackcap, it repeats the same missile thrush phrase over and over again.

Plenty more Warblers arriving, all these from one trip to Newport Wetlands!

One bird that’s been on my list to record for a while though is a Common Redstart, as they’re often quite hard to approach whilst singing, and most of our local populations are upland, where recording conditions are challenging as it gets quite windy the higher up you get and the less objects you have to hide behind. I had to use an old stone wall / building to get this recording.

Nocmig

Tempted todo a separate blog on Nocmig as so much has happened! Barn Owl, Spotted Flycatcher, Water Rail, Little Grebe, Curlew, LRP’s, Oystercatchers and so much more! Here’s a short video clip of the Barn Owl.

Autumn Migration

I can’t help but feel the tension this time of year, as it’s a race for many bird species, to complete their breeding task and start to make their way south again for the winter. Some of my Nightjar are either during their second clutch, or are thinking about starting one, but they really want to get a move on, otherwise they risk the unpredictable weather of autumn. Pair number 1 are still roosting with their first clutch of chicks, but pair number 2 have finally kicked out the kids and look to be getting cosy again. I know this because she (Pebbles) is starting to roost with Rocky again at his favourite roost site, which I predict is where she is going to lay her second clutch. As a result he’s started to sing a little more, which has spurred on more territorial behaviour from neighbouring Male Midnight, who wasn’t on his usual log today. I suspect he’s on the edge of his territory, to make sure that Rocky doesn’t get any bright ideas and move in on his girl (which does happen quite often with Nightjar).

Their movements, roost site choices and behaviour all makes sense, the more you get to know these birds. Whilst it might appear random to us at first, there’s always a reason for their choice of roost and the more I’ve learned, the more I realise that their requirements are particular, but quite simple. So simple in-fact that there are things we can do, to ensure their breeding habitat stays in suitable condition, for as long as possible. It’s something I intend on discussing with NRW, Woodland Trust and any other land owners that happen to have breeding Nightjar, as their success rate is pretty low, at just 20%, but we can increase their chances that with some careful land management plans.

Nocmig

Finally, Autumn migration is picking up, and I’ve started to get more waders on my Nocmig recordings. I share this experience with close friend Craig Constance, who is also recording at his home, and despite living just a town away from each-other, we are both getting very different results so far. Just this week Craig has managed to get a Quail!, Green Sandpiper and a steady movement of Tree Pipit. Being on the canal, I seem to be getting quite a number of Common Sandpiper so far, but even with the canal, anything could happen, no matter where you live. Always expect the unexpected!

We’ve both been keeping our ears open for key species, Quail was one of the species that we hoped to pick up, so for Craig to get one already, was quite exciting! Wood Sandpiper was also on our list of species to look out for, and before peak has even arrived, there it was! My first Wood Sandpiper, and the classic call too, so no mistaking this for anything else. Who would have thought, over Sebastopol we’d be getting such a variety of species, some of which are quite the rarity. We usually get one or two on the coast, especially picked up at Goldcliff, and now I’ve heard one from my Garden, i’m eager to go and see one on the flesh, so I’m hoping we do find one soon. We do seem to be getting good numbers in the Uk this autumn so it’s just a matter of time.

There isn’t much left singing now, so I was particularly happy to hear two Male Greenfinch in full song on the Gwent Levels this week. Most certainly not a common sound anymore due to declining numbers. Such a pretty song too, which has been on my wish-list to record for quite some time.
The only birds that are still singing, are birds that are second (or third) clutching. You’ll probably notice that Wood Pigeons are quite vocal again too, and I’ve even seen some carrying twigs to build a second nest, or repair the first one.

The only other singers on the levels right now are random Wren’s, Cetti’s, Linnet and Goldfinch, but as you can hear below, the Linnets aren’t giving it their full effort anymore.

The Dawn chorus has been pretty poor the last couple of weeks and I’m not sure if it’s just the winter Robin song creeping in as autumn approaches, or whether it’s birds going for a second clutch, but either way, it’s nice to hear some birds singing in the morning again.

I’ll leave you with a few more photos, firstly of Midnight who’s still roosting on his favourite log. He’s the only Male that has stayed with the female throughout the entire incubation period, which I think is a reaction to the fact that they failed their first clutch due to predation. He’s keeping a close eye on her, and in doing so, gives her an early warning system should another predator come lurking. Two sets of eyes are better than one after-all.

Birthday Blog

Today I plan on doing absolutely nothing for my Birthday. It’s the weekend, the weather isn’t the best and last night I took a Piriteze tablet, which has knocked me out for the day lol. I got bit by three mosquitoes whilst recording nocturnal waders at Goldcliff Lagoons the other day which has left me itchy all over. Even though piritize usually helps with this sort of itchiness, I have a bad history with piritize, so I don’t take them often. They do make me extremely drowsy and I learned this the hard way as I ended up in A&E a few years ago after taking too many!. They completely knocked me out, like a very strong sleeping tablet. Jodie literally had to peel me off the floor, it was quite worrying at the time. I laugh now, but truth is, it was very stupid of me to not take the correct dosage, so please always read the box before taking any new form tablet. They might be small but they pack a punch!

Anyway, quick update on Nightjar’s. I have three pairs that have successfully fledged two chicks so far and the 4th has just started their second clutch having failed their first. I think they’ve only laid one egg like last year but I refuse to flush her off the nest to find out, like so many nest finders and photographers do.
I’m going to take this opportunity to educate people about Nightjar photos they might be seeing online. IF you see a female Nightjar on a stick with her eyes wide open, or wings in an awkward position, it’s because she has been flushed off the nest. I’m seeing plenty of photos online from irresponsible photographers who don’t know what they’re doing and are looking for that ‘perfect photo’ with the birds eyes open. If you do your job property as a wildlife photographer, which is to NOT to disturb them, their eyes should remain shut or slightly open, called ‘slit eye’. This shows that the bird is trusting in their own camouflage and stil believe they have not been spotted. If their eyes are wide open, you have got too close and the bird fears for it’s life. These birds should only have their eyes fully wide open at night and it makes me sick that there are people out there who are willing to disturb females off the nest just to get that one shot. Absolute idiots! I could easily name names, but I hope that they’ll read this blog and know that they aren’t fooling everyone. There will always be people out there that know the truth behind the photo.

In other news, we had a few days of sunny spells which has brought me back into bug hunting mode, which has finally lead me to find my first pink morph grasshopper! I think it’s a Field Grasshopper but without its usual colour features it’s actually quite hard to tell without it singing. In the same patch was a few Mottled Grasshoppers too and I seem to be finding Roesel’s Bush-crickets wherever I go now! With hundreds singing on the Gwent Levels, Llandegfedd, Pontypool Park, The Race Meadows, Green Meadow, Cefn Ila, and most unusually at an upland site near my Nightjars too. I’ve seen more long-winged Roesel’s this year than any year previous, so I believe this year is one of those exceptional years where conditions were so perfect, almost perfect enough for plague levels of dispersal. This does happen from time to time with locust species across the planet, but I don’t believe it’s anything to worry about here.

Here’s a slomo version of this very loud iconic, electric sound. In slowing the recording down you also bring the pitch down, which means everyone can enjoy the sound of this cricket as some may not be able to hear them as they’re so high pitched and we all lose the top range eventually. I’m losing it slightly in my right ear and I’m sure it’l catch up with me eventually but till then, I’m making the most of it.

Another loud but high-pitched grasshopper is that of a Long-winged Conehead, which is a personal favourite as slowing it down reveals this incredible pattern, otherwise inaudible at full speed.

I’ve done a lot more sound recording this month than photography, making the most of what’s left of summer weather. During surveys I’ve put out unmanned drop rigs, just to maximise productivity whilst at these beautiful locations on the Gwent Levels. I’ve really come to love the place even more after these surveys. Every tide sounds different, as the weather totally changes how the water hits the shoreline. Sometimes it bubbles up thru the mudflats, and others it crashes in like waves on a sandy beach. Here’s two examples below, both high tide in the exact same spot, sounding totally different both times.

I also took a trip to the Canyon, where I found plenty of butterflies, including a Humming-bird Hawkmoth feeding on bramble flowers on the cliff-face. I went there to record the sound of the small waterfalls, but I think I was a little too close now, listening back it can sound a little ‘tinny’ and that’s because the waterfall hits many rocks on the way down, so it’s just a collection of very small sounds, so I would have been better off further away, to capture the sound of the entire waterfall as a whole, instead of just one section of it. Lesson learned. It’s the equivalent of photographing a beautiful landscape with a macro lens.

Goldcliff Lagoons

Goldcliff Lagoons is a classic example of brilliant conservation. The management plan here, to keep the site in pristine condition for breeding waders, is almost perfect, keeping the grass short with cattle, and the water levels just right so that it’s not too deep, and not too dry, leaving just enough shoreline to keep many wading species content but also enough deep water to keep a constant ecology of aquatic invertebrates that provide a constant food source throughout all four seasons. That in conjunction with a high electric fence around the perimeter to keep ground predators out. As a result it’s become a safe haven for many declining bird species such as Avocet, Little Ringed Plover and Lapwing. Post-breeding we start to see the arrival of winter migrants and amongst the hundreds of Black-headed Gulls, were plenty of Ringed Plover, Little Ringed Plover, Common Sandpiper, Black-tailed Godwits, Dunlin, Knot, Redshank, Whimbrel, Curlew, Lapwing, and some fresh arrivals in the form of a single Bar-tailed Godwit, Greenshank, Sanderling, Green Sandpiper, Whinchat, Yellow Wagtail, and the infamous Glossy Ibis that’s been present for a few years now: So long that’s it’s been named ‘flossy’.

I timed my visit straight after a survey, as it was high tide and still fairly early with my survey finishing at 6:50am. It’s nice when you have high tide line up with the early morning sun, as theres usually more birds present and they’re all lit up by the morning sun, with all the platform and hides on the east side of the lagoons. I didn’t get much time to myself as it’s a popular location for birders, but here’s a few short recordings from the Snipe Platform, of Black-tailed Godwits feeding and a single Oystercatcher performing like it was spring again.

Beings I didn’t get much time alone, I planned a late trip at the next available high tide, which was at 10:30pm. Being dark by then, you couldn’t really see that much but I did see / hear large numbers of Curlew and Whimbrel arriving just after sunset and plenty of arriving waders making sound, but unfortunately the wind levels were too high for sound recording with a parabolic dish, so I’ll have to try again.

This late visit was the reason why I got bit by Mosquitoes 3 times, as there was a HUGE swarm over the lake. So large that you could hear the swarm over the top of the wind and thousands of waders!

Whilst I’m on the Nocturnal, here’s a recent heterodyne recording of a Pipistrelle Bat from a Bat Survey. Heterodyne is a process that transposes the ultrasonic frequencies produced by the Bat, down to an audible pitch that we can relate to. It’s still not the best way to appreciate the complexity and tonality of these Bat sounds but it’s the quickest way to ID Bats in the field, with use of a Bat Detector.

Nocmig

Autumn migration is finally here and I’m really starting to get some decent numbers of waders coming over my house in Sebastopol. I’m lucky here as I’m not too far away from the canal, which the birds are clearly using to navigate during the night on their migration.

There was one night that was particularly good, as we had short rain showers and low cloud, which wasn’t enough to stop waders from migrating, but was enough to bring them lower to the ground and therefor easier to pic up by the microphone. This resulted in a movement of 9 Dunlin, 7 Oystercatcher, 1 (possible 2) Redshank, 2 Moorhen and 1 Common Sandpiper. Here’s a few recordings showing mixed flocks also, which proves that these birds are often moving together. Since this day I’ve had some days with nothing at all, and the odd Oystercatcher, with a few Common Sandpiper. Autumn hasn’t even started yet so it should be an interesting season to come! Who knows what will end up over the house .

Nightjar + Updates

Some good news, some bad news, such is the nature of nest monitoring. In this woodland I have 7 pairs, but I’ve only managed time to find 3 nests so far. 2 of these nests are doing great, both with two chicks and both getting bigger each day, but as the nest gets smell from droppings from both the parents and young, it starts to attract predators, and the worse happened for my 3rd pair that seemed to get their chicks to a decent age, but the nest was found empty, with just a few chick feathers that were broken off. I didn’t have a camera on this nest so it’s difficult to know what the cause was, but this pair failed their first clutch last year also and managed to start again with their second clutch fledging one chick. Below is a male that I’ve come to call Midnight, as he’s particularly dark compared to my other males. Males are usually darker than females, but this guy takes it to another level. He’s the male of the failed pair, so is now sticking close to the female again where-ever she may go, so that they can start over. He’s even roosting on Rocks which makes sense now the nights are getting cooler as that extra warmth sitting on a rock that’s been baking in the sun all day will most certainly give them an extra boost of energy at sundown.

I don’t usually photograph birds on the nest, but I've been getting requests to see the chicks on Facebook so here we go. There are two showing in the photo, but the second is much harder to spot. They’re just getting too big to stay underneath Mum, and it this time lines up perfectly with their adult plumage coming into play, so they are becoming less dependant on mothers superior camouflage.

We’re so lucky in Gwent to have such a variety of fauna and flora and I don’t appreciate it half as much as I should whilst I’m out and about. Usually too busy to stop and observe the ground, especially when you’re focuses on Nightjar, you get a little tunnel vision, but it’s surprising what you do find if you just set aside a bit of time. There are some species that you just need to make the time for, like the Scarce Blue-tailed Damselflies in upland Gwent ponds, if you don’t look, you won’t find them, but there are other species that you just need to get lucky with, and luck was on our side as a Silver-washed Fritillary was sapping moisture and minerals from a clay patch right next to the car along Albion road, pontypool.

Sound Recording

I’ll start with a mystery, and if you do have an idea of what this begging sound might be, please get in touch as I’ve suspected many things but cannot find any reference material that matches.

There were a few Woodcock roding so I thought it might be a begging chick but I’m honestly not convinced it’s even a bird at this rate. This is the first decent recording I’ve got of a roding Woodcock but I’ll try to improve on this next season as it’s a very cool sound.

The star of the show was of course this beautiful performance off this Male Nightjar that does have a very distinctive song, where the inhale section of the song, also described as the minor phrase, is quite low pitched in comparison to its major phrase, making him identifiable, even by ear, so long as you know what you’re listening out for.

Throughout the season I have been observing Goshawks nearby that have been taking food back and forth, so I suspected at the time they were nesting quite close but till now I’ve kept my distance as I’m not scheduled and I have no interest in disturbing them, but in the last few weeks the chicks have fledged and are venturing much further away from the nest site, so it was a matter of time walking the woodland paths that I eventually came within reach of my recording gear. This is why I love sound recording with a Telinga Dish, as unlike photography, you don’t actually need to see the bird to appreciate it, which allows you to appreciate wildlife from a much greater distance.

Nocmig

I’ll end with a few updates from my Nocmig recordings, which have just started to pick up again as birds are starting their autumn migration.

So far I’ve had Little Ringed Plover, Oystercatcher and a few morning extra’s in the form of Swift, Linnet and Raven, which I don’t usually get here.

Babies!

So I know everyone loves to follow the Osprey projects around the Uk because of the live cams ect, but also because the birds are identifiable so people can really track their progress. Thousands of people watch avidly and know them all by name by now, and I know most pragmatic naturalists are probably cringing right about now, but I do think that in giving individuals names, that people start to realise that these birds are unique, and aren’t just carbon copies of each other. We all have individual characteristics and it’s no different with wildlife. An example of this can be seen below, as last year I found a Male Nightjar that would roost on rocks instead of the typical logs, but only when the weather was bad or it was due to rain. I have a few reasons why I think he would prefer a rock in these circumstances. Rocks don’t sway in the wind, the don’t attract Wood Ants, and should any sun make an appearance, the Rock will warm up. There may be no reason what so ever and whatever the reason, this is the only Nightjar in the area that I’ve documented doing this year on year.
As a result, I’ve come to name him Rocky, and his sandy female Pebbles.

I’ve only found two nests so far in this woodland, with another 4 to go but both females have managed to hatch an egg on the same day, so it’ll be interesting to see how they both develop.
The other pair have chosen the burnt habitat and I’ve come to name them Ash and Tinder. I think this pair is a young pair, as the spot she has chosen to lay her eggs is, well, questionable to say the least. I’ll keep you informed of their progress this season but anything could happen with lots of predators in the area.

One thing I am keeping an eye on is the weather as we’ve gone from 30c heatwave to plummeting temps with strong winds and rain. Not so great for breeding birds, but I did take some of the storms as an opportunity to record some rain storms. If you suffer with mental health issues like myself, you might find listening to these before you sleep really helpful. Stick the headphones on and relax.

Whilst we are on sound, on one of my nocturnal monitoring sessions with the Nightjar I come across a displaying Snipe. This sound is worth talking about, as if you didn’t know already, this sound is produced mechanically. It’s referred to as ‘Drumming’ as the sound is produced during a flight display, where the tail feathers are stiffened and spread out in such a way that the outer feathers catch the air and produce this incredible sound. I heard it for the first time this spring on the Gwent Levels, but this was the first time I’ve heard such a long extended performance.

I’ll leave you with a few ‘arty’ shots of Hard Ferns, Large Skipper and an Emperor Dragonfly on a short social distancing walk with Lee Gregory. Lee is such an asset to Gwent, his natural history knowledge is incredible and he’s such a nice guy! Hopefully when this lockdown is behind us we can get out more often.

Nocturnal Migration

For years I’ve been nagged by my good friend Craig Constance to start recording ‘Noc-mig’ which essentially means recording nocturnal migration by putting a recording device on record all night. I’ve never been a fan of the idea, as it’s taken me a long time to save up for all of my equipment and the last thing I wanted to do was to leave it outside where it could either get stolen or damaged by typical British weather. Sound recording gear tends not to handle water very well. So what made me change my mind? Well, Craig pointed out a few people that have uploaded information about Nocmig online which revealed a trade secret to ensure 100% waterproof coverage over the gear, whilst unaltering the overall sound quality. I didn’t think such a thing existed, especially after being told that the answer to the problem was, clingfilm! Turns out that clingfilm is thin enough to almost be transparent to soundwaves but thick enough that no water can penetrate. If sound quality was important then I don’t recommend this, but if you’re desperate, try it! I think you’ll be as surprised as I was.

So now is the time, peak spring migration season and on our first night of leaving the recording gear out, we have both had some really interesting passerines, with Oystercatcher, Teal, Redwing, Black Headed Gull, Mallard, Moorhen, Song Thrush and Pied Wagtail so far. I’ve had Oystercatcher following the canal before, but getting these again so soon makes me realise that they probably use the canal system annually as a way of navigating during the dark.

They might not sound great, but they appear really obvious on when looking at the spectrograph.

Oystercatcher Spectograph

Oystercatcher Spectograph

My setup will likely change over time once I convince myself that it’s worth putting the more expensive gear out, but for now I’ve stuck my Zoom H6 recorder inside a plastic box, hit record, put a layer of clingfilm over the top and then just put one of my Rycote fur covers over it to eliminate raindrop sounds on the clingfilm and take off a bit of the wind noise. Any material would work so long as it’s not too thick that it muffles the sound.

Noc-mig Setup

Every now and again you get something that you’re unfamiliar with, as nocturnal sounds are vastly unrecorded, especially migration calls, but this recording below still has me a little unsettled as it doesn’t sound like your typical Tawny Owl to me. It goes to show what you can learn when leaving recording gear out like this and It’s exciting as you really don’t know what the night might bring. If you are self-isolating, this could be a fun little project for you to give a go, if you have children I’m sure they would enjoy listening back to the recordings to see what they might have captured. All the while, you are contributing to a little citizen science, as it’s always valuable to know migration routes.

Free for all comes at a cost.

Just when I think things are on the up, I get reminded just 8 days into Llandegfedd being back open to public, just how much the site is set on a downwards spiral.. I really hope new management turn things around as the current free-for-all setup is coming at the cost of our environment. I arrived to see Dog’s running around off lead on the island , a site that used to have breeding Lapwing. A fisherman set up very considerately right in front of Bert Hammar Hide, Poo Bags are thrown everywhere, Dog poo everywhere and plenty of litter. Welsh Water has done a lot of work this winter repairing the hides, with new roofs and bin additions, but I’m starting to think that all this encourages is for people to use the hides as picnic areas and not for their intended purpose. Just 8 days in and the bin is overflowing in Green Pool Hide and as a result, bottles, cans and wrappers surround the hide. Green Pool never saw litter prior to the installation of these bins, so I think they need to go. I was also very disappointed to see four silver birches cut down. These birches were planted as part of past conservation efforts and were reaching a good age, but it was deemed a necessary loss as it enabled DCWW to cut the grass with the tractor to save time. Three Boats were fishing right in Green Pool inlet and as a result, flushed what little Teal are left on site. There’s no policing of the site what so ever, which is exactly why these things go totally unnoticed by the rangers. This is what it’s like now, in wet and windy conditions, so you can imagine how bad it gets on sunny weekends during the summer.

Moving onto more positive things, I spent some time with the Macro lens, and I have a ‘thing’ where if I photograph something, I need to find out what it is, which is why I pick and choose what I photograph as it can often lead to a headache, as not all species are identifiable without use of a microscope. I just need to get some decent books. If it wasn’t for this website - https://www.naturespot.org.uk/ - I wouldn’t manage at all at the moment. I bought a Moss book but turns out it’s Arable Garden Mosses only, so not much good for me.
Any recommendations, please let me know! I want to grow my book collection.

A Week for Welsh Bugs!

I’m back on the Nightjar, this time at a completely different location, just to switch things up a bit . So far I have 3 pairs , including this Male that’s switching his roost up every night but does come back to the same ones every now and again. Each roost he uses though is pretty well covered so I won’t be trying to get close photographs of this one, which does not matter to me at all, as once you’ve spent as much time as I have researching them, just finding one without disturbing them gives you such a great sense of achievement and most of the time I just rock up, look at them through my bins from a distance and go straight home.

Male Nightjar

The great thing about searching for Nightjar, it requires similar searching methods to how you would search for rare insects, paying great attention to the small details. I always bring my macro lens with me and this week, I’m so glad that I did, as not only has it been fun photographing a variety of different species in beautiful sunshine, every now and again you stumble upon a gem!

A short walk along the Gwent Levels and upon arriving back at the car, I noticed a very small Hoverfly that was so brightly marked I thought it was a wasp. It just to happened to be a member of the Chrysotoxum family which are ‘wasp mimics’ and if it weren’t for the featherlight flight pattern, it would have had me fooled!.
I’m not going to pretend like I knew what it was in the field, as I didn’t. All I knew was, I’ve never seen one of these before, as I do have a photographic memory. I managed to snap a few different photo angles, trying to get the full back pattern and the antenna which are usually key features in identifying hoverflies. There are around 280 different species of Hoverfly in the Uk, some of which are isolated populations in specialist habitats. In the case of Chrysotoxum, they are described as being ‘The Difficult Five’ as they are very similar and usually requires close examination by an expert in order to ID them. Luckily for me I always take multiple angled pictures when photographing insects as I’ve learned the hard way that it’s not always possible to ID via a photograph. This is why so many bug specialists take home life samples to study under a microscope.
As soon as I got home I looked in my Hoverfly book which I downloaded on my phone, it’s called ‘Britains Hoverflies’ and it’s written by Stuart Ball & Roger Morris. The book was great, and the description / images provided me with enough detail to rule out a few species straight away and it was looking good to be Chrysotoxum Verralli. This is still new territory for me though, so I went straight to my ‘bug friend’ Liam Olds, who has a vast amount of bug knowledge and is very open to receiving the odd ID request from me, which I’m truly grateful for! He quickly checked for key features and as I suspected, it looked good for Chrysotoxum verralli, but he requested I still ran it by the Uk Hoverflies facebook group to be 100% sure, as if it was C.Verralli, it would be a first record for Wales!

The stakes just went up! so I popped all my pics on the facebook group and who should comment, but the co-author of my Hoverfly book! Roger Morris himself! and confirmed that it is indeed Chrysotoxum verralli. I couldn’t have had a better person to confirm that for me so I’m chuffed to bits.

Chrysotoxum Verralli

I shouldn’t get too excited though, as this actually happens quite a lot. In the same week, Martin Bell discovered a Sandrunner Shieldbug in Slade Wood which is another first for Wales! The truth is, there’s probably a lot more out there that we simply have not discovered yet and I am living proof that anybody, no matter how much experience you have, can discover something new, if you just slow down and pay attention to the details.

Gwent Naturalists

If you’re on Facebook and live in Gwent, you might be interested to join a new group called Gwent Naturalists.

It’s an extension of the Gwent Birders group that has over 600 members so far and every now and again we get questions about butterflies, moths, dragonflies and flowers, which is fine, but it made me realise that we could do with a group that covers more taxonomic groups.

We’re very lucky in gwent to have dedicated naturalists that have spent a life-time studying nature in their respective field. Whether it’s spiders, slime moulds, mosses, micro moths, birds, bats, reptiles, flowers, bees, beetles, you name it, there is somebody out there with the knowledge.
This isn’t to take away from the existing - South East Wales Biodiversity Records Centre group - which I still highly recommend you join.

The Gwent Naturalists group isn’t just a place to share photos and ask for ID’s, I hope that we can use it to discuss conservation topics in our area, organise field events, and generally work together to help encapsulate our knowledge and work together towards a common goal.


My second pair of Nightjars were victim of an egg thief just two days from hatching, so I’m giving them plenty of space as they choose their second location for clutch 2, which is so far looking to be a much wiser choice, in a clear-fell that has much more cover, making the nest less exposed. I did wonder if their first choice was a good one, as it wasn’t far from a major dog walking route, and they did get quite a few close fly-bys from Jays and Great Spotted Woodpeckers, but the list of predators for ground nesting birds is huge, so it’s lucky they’ve adapted to this by not putting all their eggs in one basket, having a second clutch as a backup plan should the first choice go wrong. With the hot weather though, I’ve turned my attention to the vast amount of insects that are now at peak.

I did note 3 Silver-washed Fritillaries on the wing this week at a local woodland which could be a good sign that this species is spreading out. I usually go to the Forest of Dean to get my Silver-washed fix but instead of doing that I’m going to make more of an effort this year to find them on my doorstep. I’ll leave you with this incredibly out of focus, cropped image :D

Shape Conforming

I hope you’re not getting tired of hearing about Nightjar but honestly I don’t care haha. Spending time with one species, learning more about their characteristics and behaviour is what I love and it’s the only way you’ll ever get a chance of photographing this species in the day. I’m now on my 4th pair and my 7th individual (yet to locate the female of the 4th pair). I find it interesting that each pair has chosen a different type of habitat, or at-least the same habitat at different stages.

  1. 3-4 Year Old clear-fell, mostly small-medium sized trees

  2. 1 year old clear-fell, only bracken, grass.

  3. 3 year old clear-fell, mostly grassland, bracken and heath

  4. 3 year old clear-fell, totally rocky habitat with bracken between.

It goes to show how versatile they are, so long as there is suitable habitat around them for moths, they’ll roost almost anywhere there’s suitable cover.
The pair that’s chosen the rocky habitat is the one that I’m most interested in, as he’s also choosing to roost on rocks, rather than logs/sticks. If you look closely, even the shape of his back appears to match the shape of the rock. I wonder if this is strategic? Shape conforming is common amongst species that rely on camouflage to survive and they do appear to match their chosen roost spot. If on the end of a log, they’ll sit tall, short, tail town as if they’re part of the end of that log. If they sit across a stick, they’ll sit in the same direction and flatten themselves out.

As a contrast, here’s the female of pair number 3 showing that typical flattened out pose that matches the long shape of a stick. I loved this chosen roost spot, but it’s doubtful she’ll use it again though as she looks ready to burst. I’m surprised she hasn’t laid yet. Maybe she has and her first clutch failed? I hope that isn’t the case.

I’ve also been studying their vocalisations but I’ve needed a few years worth of field recordings on Nightjar, in order to confirm a theory that you can identify individual males by their song. The way you would do this is to work out the average BPM, length of phrases and also the frequency of both exhale and inhale.
I’ve collected so far at-least 6 different males, though I’ve focused on returning to the same territory for the last 2 years in the hope to confirm it with one individual male. So far it looks like I can confirm this theory, as I’m finding only a 0.8 difference between the BPM recorded in 2017 to present day. A couple more years worth of recording Males and I should be able to give more weight to this theory.
The analysis is actually pretty easy and could even be done in the field so long as you had a laptop to return to. I’ll publish more details about my methods at the end of the season.
