Fun book about what I'm talking about in particular, the odd language hacks use "Romps, Tots and Boffins: The Strange Language of News" by Robert Hutton (2013) Famous people have romps, not sex, small children are tots, and scientists are always boffins roberthutton.co.uk/romps/

A you know, it's almost always deliberate, it's about avoiding straightforward words or repeats, and it's almost always euphemistic. In almost 40 decades of journalism, I've always tried to avoid it in my writing

One report says it was a scuffle, another a brawl. Which is it? Or, maybe it was something else? A broil perhaps? An affray? Maybe it was actually a rumpus or perhaps even a fracas... #AwfulJournalese

Despite my best efforts over the last few years, I still hear people say that moths are dull, grey, brown...well, some of them are grey and some of them are brown, but there's so much more to it... #teamMoth imagingstorm.co.uk/lepidoptera-...

Was expecting more, given that it didn't get below 20C here last night, but at least I got a chance to photograph the Bordered Straw. Also made me realise that I needed to correct my records as only had Scarce Bordered Straw previously this year

I remember a Jon Pertwee episode back in the 70s when the Master turned up in a TARDIS that wasn't broken, it was a shiny metal lozenge-shaped thing, presumably the native format. He could also fully control his spacetime destination

Another Bordered Straw, or perhaps even the same moth, turned up to the lamp in the back garden this evening. So a quick photoshoot before releasing it out front Bordered Straw, Heliothis peltigera #teamMoth #mothsMatter

There was carnage during nesting season one morning when I didn't get up early enough. But even now I see it and the Robin and a Wren suddenly appearing and pecking something I presumably missed on the pation or "lawn"

30 moths of 12 species in 16C VC29 last night #teamMoth Including what seems to be a quite late Bordered Straw, which I now realise I haven't previously photographed properly and didn't retain this morning! Dammit!
Agonopterix nervosa, the Burnt-tip Buff. Only the second one of the year here.

Yes, it could be that, although it's only one of half a dozen places, and the other places don't seem to have had repeats over the last three years like this one has, despite the now-rubbish vegetation

Yes, that *is* what I thought, it's just the notion that new migrants are turning up at the same patch each year despite the lack of foodplants seems odd...

David Bradley @sciencebase.com · 25/09/2026
Patch Earith-Over had 5 earlier this pm. Couple of dozen there in '23 when it had clover. Now it's mainly thistle and hairy ox-tongue. Makes me wonder whether these are somehow surviving offspring of offspring, otherwise why immigrate to a dead patch?

David Bradley @sciencebase.com · 25/09/2026
I also did my best not to double count, not clicking a second sighting within 20 metres or 20 seconds of the first click. So, I am confident in this 100+ number

David Bradley @sciencebase.com · 25/09/2026
Astonished, I was!

David Bradley @sciencebase.com · 25/09/2026
It was absolutely mad. But, it's a dense patch of mixed pollinator plants, alfalfa, sanfroin, clover etc, drilled a couple of years ago. The CYs have obviously bred well here. Ditto the Common Blue which were present in the 100+ too

Just 34 moths of 10 species last night, 12 of them Lunars

David Bradley @sciencebase.com · 25/09/2026
I did a 1200m peripheral walk around the field (with permission), took 45 mins, counted 108 CYs, reckon there is likely to be the same number again that were basking or hidden in the depths of the field. Maybe more... 100+ Common Blue too #Butterflies www.sciencebase.com/science-blog...

Meanwhile, a friend spotted a massive flux of 100+ Clouded Yellow on mixed alfalfa/clover/trefoil fields in a nearby village. It would have been rude not to check them out. I counted about 50 CYs, and got an in-flight snapshot of one the males haring about #UKButterflies #MigrantSpecies
The Clouded Yellow is a migrant to the UK and doesn't, AFAIK, survive our winters (it will eventually, but needs its foodplants to be in bloom over winter to do so, not just about temperature as it doesn't hibernate). Nevertheless, it does breed here, and has done on this farm patch as there were lots of pristine specimens around. A friend saw hundreds a couple of days ago, I think I topped out counting at about 50.

Slightly different view of the Cinereous Vulture, showing (sort of) the origin of the shade in its name (cinereous, meaning ashy, as in in-cinerate) www.sciencebase.com/science-blog...
Cinereous Vulture, or Black Vulture, Aegypius monachus. Its binomial loosely translating as "Egyptian Monk"

For anyone who likes to see other people's holiday snaps, here are mine from our recent trip to Mallorca featuring Booted Eagle, Cinereous Vulture, Blue Rock Thrush and some scenery and stuff www.sciencebase.com/science-blog...
Blue Rock Thrush about to take off. Despite it's thrush-like appearance and its thrush-like song, it's actually a "chat" rather than a thrush...apparently...

Exec Summ: Citizen science data often miss species because people tend to record sightings only where public access is easy. To get a complete picture, we need to encourage people to log common species near their homes and at the same time improve access to private natural areas for rare species.

We were away just a week, but my how it's changed. 9C last night. 42 moths of just 21 species. The Lunar Underwings are back and a Deep Brown Dart was NFY too
Various forms of the Lunar Underwing moth, three dark, one lighter brown, one orangey-brown

Avian highlight of our recent trip to Mallorca has to be this vulture, albeit a rather distant sighting #BalearicBirding #Spain
Cinereous Vulture near Sa Figuera, Mallorca, photographed from perhaps 500-600m with the bird high up.

Bit of an earache...olive oil spray until prescription came in did nothing, the actual medication contains acetic acid as an active ingredient...so I've basically been mixing salad dressing in my auditory canal. Didn't add mustard, that seemed like a recipe for disaster

David Bradley @sciencebase.com · 14/09/2026
Yes. I do a per session average for the whole year and work it out for May-Sep inclusive too and it's been much higher this year...the one thing that was massively down was Box, there were hundreds some nights last year, but their larvae ravaged our neighbours' hedges and there was a famine

David Bradley @sciencebase.com · 14/09/2026
400+ is way up on what I normally see, usually just 350-370 or so. But absolute numbers are in the 15000s and usually I get 7-9k. Something very different. Could be my "wilding" or its just chance and a weird spring and extreme summer

Clif is in the house! Clifden Nonpareil, Catocala fraxini, one of 67 moths of 22 species to the lamp in wet Cottenham last night #teamMoth Only my second ever Clif in 9 seasons of mothing
Closeup of the face of a Clifden Nonpareil moth. This is quite the beast, this one has a wingspan of about 80-90mm

I also worked with the editor of Gas Jar (the young members' mag) and renamed and rebranded it as New Elements. My column in there I called Elemental Discoveries and I launched it on the web in 94, it morphed into my Sciencebase website in 99! I'm old.
