Autumn update from Dol, 2016

Published in Nature Watch

Steve Jones has kept up his Nature watching through Hvar's mild autumn weather. More dragonflies, but less birds than expected.

SJ, 23 9 2016. Do you know much about dragonflies on the Island? Over the Summer I have seen several and I know Norman nearby has also seen similar numbers.

While I know a few of the more obvious ones, I am puzzled: one thing I do know is that they like water in which to lay. The dragonfly life cycle is for the most part spent underwater and they only emerge as what we see towards the end of their life and to mate. So I am puzzled as to where they can possibly lay eggs, I only know one source of water down near the airfield and I don’t believe from there they would travel up to Dol. I often think they could be laying in the numerous wells/water storage places in the fields but most are covered and I don’t know how they would emerge. One species described to me was the Golden Ringed Dragonfly and I've read that this likes fast flowing water so I am even more at a loss.

I was down near the airfield yesterday and several of just two species that I could recognize were flying, including the Common Darter. One of the species tended to be flying joined to their mate, there were several of these.

Norman and I are both seeing more Dragonflies than either of us expected here in Dol – more investigation needed.

Apart from the dragonflies, I was in Jelsa on Wednesday (September 21st) and saw that there were still Swifts around, with a few House Martins scasttered amongst them. And the odd Swallow was still around yesterday. A friend in the UK told me that the Swifts departed from our street pretty well in the first ten days of August.

VG, 23 9 2016. Yes, actually there are many more sources of water than you'd think, off the beaten tracks, but also in the fields. A lot of the enclosed wells have an open basin on top, which can be home to all sorts of insects, including water snakes - one of those regularly basks in the cistern beside my land, heading off reluctantly into the undergrowth after the water has completely evaporated.

Of course the wildlife population is adversely affected if the fields have been doused in herbicide. Talking about herbicide, did you see that the sale of Cidokor/Roundup is to be banned in the EU from October 1st, together with 11 other glyphosate-based herbicides? Good as far as it goes, but it still leaves 12 other glyphosate herbicides on the market!

I'll look forward to hearing the results of your dragonfly investigations. A good place to see them is in the environs of Humac, where there are some lovely natural pools where the horses and hunting dogs drink, and butterflies abound, as there are no poisoned fields in the vicinity.

VG, 3 10 2016. Have you seen any bats recently?? I'm really concerned at how few there are, compared to crowds up to about ?10-12 years ago, counting from when I first arrived in Pitve in 1988. And bee-keepers tell me they have no honey this year, and are taking their hives to Šćedro, where there are fewer environmental poisons around.

SJ, 3 10 2016. Bats? Yes, a few. Some around the house but not often or regular. Couldn’t identify species either.

I've just returned from Stari Grad where I saw a few Swifts flying around and still one Swallow, so I suspect it will be much the same in Jelsa. Can’t remember which evening, in the latter part of last week and very high up about 150 birds went over the house, by far the majority were House Martins with a few Swallows amongst them.

VG, 25 10 2016. Maybe this recent article by Chris Baraniuk about ring-necked parakeets in the UK might be of interest? I used to love watching those birds squawking their way to and fro across west London! More recently I learned that the same kind of parakeets arrived in the rgion of Heidelberg in Germany and Barcelona in Spain at around the same time as they were first seen in the UK, sometime in the 1970s. I wonder where they came from, and why they spread over parts of Europe?

SJ, 25 10 2016. Yes – thanks for the article, not being a frequent visitor to London I was overjoyed to see some parakeets while I was at Twickenham for a Rugby match some years ago, life doesn’t get any better than that – Rugby and Bird Watching!

I am helping neighbours pick Olives for my sins for another week ( I’d forgotten how much fun that was/is ………….. ummmm) but managed a trip to the airfield on Sunday morning: I saw at least 100 Pied Wagtails in varying sized flocks, with smaller stuff too distant to identify properly. There was also an unidentified Pipit which I will persevere with. Robins are singing everywhere now but seldom prominent . My last Swift was seen on October 23rd, it's possible that there are a few still around, but as I've not been into town I can't say for sure. I saw a Black Redstart yesterday in Prapatna. A rough count gives me around 60 species which is a little disappointing, I had expected more. But I might have missed several species, through not travelling to different locations.

VG, 25 10 2016. I'm also up to my ears in olives. Mercifully I picked my own early, with pleasing results. I'm now helping my friends and neighbours, which in some ways is more arduous.

SJ, 28 10 2016. Don’t know whether or not you can help me here. Is there a bird called a “lugarin” I heard yesterday in conversation so I am presuming it is a dialect word for something? Would you know – Serin perhaps?

VG, 28 10 2016. My Pitve-Zavala dialect dictionary defines lugarin as 'zelenkasta konopljarka', which seems to be commonly translated as greenfinch. Konopljarka is linnet. Any help? I hope those people weren't talking about trapping them. It's now against the law to trap migrating songbirds, but....

SJ, 28 10 2016. No – I think it was flying overhead – the person who was talking about it is definitely not a trapper/ hunter of anything like this for sure. Thanks for very much for that, I keep periodically hearing them but am not seeing many. But just didn’t know the word ……………. One day perhaps! I keep waiting for this book “Ptice Hrvatske i Europe” , if I ever get a copy. Have been in touch with someone now who may be able to help.

Was picking Olives yesterday and came across this spider, pretty well the same size as an Olive or just a fraction bigger and it very nearly got picked as one. The circular part of it was the size if an adult thumb nail. Tried to ID, am thinking it is a female of the Garden Spider variety (Araneus diadematus) – although I wouldn’t bet on it - of which there are many, it seems. Anyhow the second biggest I have seen since being here. Pretty impressive.

VG, 28 10 2016. That's a beauty! The biggest spider I've seen in my field was possibly a type of Black Widow, very bright, with orange stripes, perhaps about the size of a 5 kuna piece. It stayed peacefully in its web between two olive trees for quite some time, fortunately out of reach of the dogs, and then went on its way. Wondrous.

SJ, 1 11 2016. Black Redstart day. I saw the one last week in Prapatna, but all too quickly, which always makes one doubt. However I have seen a few more in and around  Dol in the last few days, including a couple in the garden. There were several in one of the fields nearby, possibly up to a dozen, so clearly they have come in from somewhere. I wonder whether they over-winter or move on.

I also saw a Wren in the garden during the week, the first one of the year for me here.

SJ, 6 11 2016. Went out briefly this morning and amongst other species was delighted with about 150 – Goldfinch/Gardelin.

Also - and a great record - one solitary Swift. Several other flocks about, I am thinking they are mainly Chaffinches but they're a bit too far away to identify clearly.

VG, 5.11.2016 Wonderful chaffinches: let's hope not too many of these beautiful birds fall into the hands of the (now illegal) trappers..

SJ, 8 11 2016. I have started collating all the birds seen this year in a table with English/Latin/Croatian names - but not dialect. I think I am at around 60 species now.

VG, Thanks Steve, we'll look forward to seeing the full list!

  • Exclusive: major supplier to brands including KFC and Nando’s used offshore companies allowing them to reduce UK tax payments, investigation suggests

    The global megacompanies supplying some of Britain’s most popular meat brands, including KFC, Nando’s chicken and Sainsbury’s organic range, appear to have been using offshore companies that allow them to avoid paying millions of pounds in tax in the UK.

    An investigation by the Guardian and Lighthouse Reports has found that two companies – Anglo Beef Processors UK and Pilgrim’s Pride Corporation (owned by Brazilian beef giant JBS) – appear to have reduced their tax bill by structuring their companies and loans in a way that allows them to take advantage of different tax systems, in what one expert has described as “aggressive tax avoidance”.

  • Nature protection rules in proposed investment zones would in effect be suspended

    There was little room for doubt about the reaction to the prime minister’s plans to scrap environmental regulations this weekend. “Make no mistake, we are angry. This government has today launched an attack on nature,” tweeted the RSPB, its most forceful political intervention in recent memory.

    Liz Truss’s proposals to create investment zones, where green rules on nature protection would in effect be suspended, represented a step too far for some of Britain’s biggest environment charities. “As of today, from Cornwall to Cumbria, Norfolk to Nottingham, wildlife is facing one of the greatest threats it’s faced in decades,” the RSPB went on.

  • Prominent members of farmers’ union express dismay after comments by Minette Batters

    Farmers are threatening to quit the National Farmers’ Union after its leader said she supported the UK government’s apparent move to scrap post-Brexit nature subsidies.

    This weekend, the Observer revealed that the government was poised to abandon the “Brexit bonus”, which would have paid farmers and landowners to enhance nature, in what wildlife groups have described as an “all-out attack” on the environment.

  • Stars of film about 500-mile trek to Scotland for Cop26 hit the road again for Bristol premiere

    There will be no red carpet, no designer outfits and definitely no limousines. In fact, the stars of the film have shunned any sort of mechanical transport and instead walked 135 miles from London to Bristol for the premiere, and are asking their audience to accompany them by foot on their last leg before the screening.

    The film, which is being premiered on the harbourside in Bristol on Tuesday evening, is Of Walking on Thin Ice (Camino to Cop26), which tells the story of a group of climate pilgrims who hiked 500 miles from the south of England to Scotland for last year’s climate conference in Glasgow.

    For more details and tickets visit the Encounters film festival website.

  • Stoke-on-Trent, Staffordshire:It feels like sitting in a crypt – I am surrounded by the skeletons of dried perennials

    I try not to make excuses so I’m just going to tell the truth: everything in my garden is dead. The drought was fierce and I was sick, distracted. I couldn’t bear to look at it but I’m trying to look now.

    It feels like sitting in a crypt. I’ve pulled up a damp chair and I am surrounded by skeletons, the limbs of my perennials dried, bent and snapped. The hydrangea’s flowers have turned to ghostly brown lace too soon, drooping leaves turned almost black like prayer flags. There is copper, rust and blood; piles of viburnum leaves dropped early in fright. The penstemon looks as if it has been set alight then frozen, its orange flames still and hellish. When the rains finally came, too late, the parched snails came out of hiding and ate everything that was left. Talk about overkill.

  • Movement aims to make the mass damage and destruction of ecosystems a prosecutable, international crime against peace

    California winemaker Julia Jackson has long grasped the threats posed by the ongoing global climate change crisis, from more intense wildfires and hurricanes to rising sea levels. But for her, those ideas crossed over from the abstract to the tangible when her home was razed by the Kincade wildfire that devastated her native Sonoma county in 2019.

    “I lost everything – all my belongings,” Jackson said. “It shook me to my core.”

  • The deaths within days of 11 sturgeon, a species unchanged for thousands of years, have puzzled scientists

    When the first spindly, armour-clad carcass was spotted in the fast-flowing Nechako River in early September, Nikolaus Gantner and two colleagues scrambled out on a jet boat, braving strong currents to investigate the grim discovery.

    Days later, the remains of 10 others were spotted floating along a 100km stretch of the river in western Canada.

  • Defra accused of ‘all-out attack’ on environment by wildlife groups

    The government is to scrap the “Brexit bonus” which would have paid farmers and landowners to enhance nature, in what wildlife groups are calling an “all-out attack” on the environment, the Observer can reveal.

    Instead, Department for Environment, Food and Rural Affairs (Defra) sources disclosed, they are considering paying landowners a yearly set sum for each acre of land they own, which would be similar to the much-maligned EU basic payments scheme of the common agricultural policy.

  • David Malpass apologises after saying he ‘doesn’t know’ if he accepts climate science

    David Malpass, president of the World Bank, faces an uncertain future this week, after the White House joined a chorus of influential figures in condemning his apparent climate denialism.

    Malpass remains in post for now but under severe pressure, despite issuing an apology and trying to explain his refusal last week to publicly acknowledge the human role in the climate crisis.
