Autumn update from Dol, 2016

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: Claire Earley’s son Rex spent six weeks in hospital after contracting E coli from contaminated lake

    Realtime pollution alerts are needed across Windermere urgently, campaigners have said, as the mother of a seven-year-old boy who kayaked on the lake described how he nearly died after contracting a dangerous strain of E coli from contaminated water.

    Claire Earley’s son Rex spent six weeks in hospital, and underwent two emergency operations, after a family kayaking trip on Windermere last August.

  • Recording of humpback whale from 1949 could also provide new understanding of how the huge animals communicate

    A haunting whale song discovered on decades-old audio equipment could open up a new understanding of how the huge animals communicate, according to researchers who say it is the oldest such recording known.

    The song is that of a humpback whale, a marine giant beloved by whale watchers for its docile nature and spectacular leaps from the water, and was recorded by scientists in March 1949 in Bermuda, said researchers at Woods Hole Oceanographic Institution in Falmouth, Massachusetts.

  • The Trump administration’s cuts to biodiversity funding have imperiled species, habitats and the people who defend both. Now the world is seeking a new way forward

    On 22 January 2024, at the inauguration of the current Liberian president, Joseph Boakai, the US-based Liberian poet Patricia Jabbeh Wesley paid tribute to the west African nation’s tropical forests – one of the places where, she said, “our fathers came / centuries ago, and planted our umbilical cords / deep in the soil”.

    The forests of Liberia are among the most diverse on the planet, home not only to humans and their ancestral ties but also to rare species such as forest elephants, pygmy hippopotamuses and western chimpanzees. They are also chronically threatened by industrial development, including illegal logging and mining.

  • Her research popularised the idea of the wood wide web, but the scientific backlash was brutal. As the author of The Mother Tree returns to the forest in a new book, she discusses her battle to reimagine our relationship with nature

    In 2018, the ecologist and writer Suzanne Simard was conducting research in the forested Caribou Mountains of western Canada when a thunderstorm rolled in. She was with her two teenage daughters and her close friend and colleague, Jean Roach. They saw flashes of lightning, heard a loud rumble and then they smelled smoke. They were forced to run the half kilometre back to Simard’s truck as the trees behind them caught alight and the air grew thick. As they ran, animals burst out of the forest: a deer, a rabbit, a grey wolf. They reached the truck with no time to spare, all four of them covered in soot and dirt. Overhead, helicopters began circling the orange-black air, dropping water on the flames below.

    Wildfires have become an ever bigger problem in Canada. The 2018 wildfires were the biggest in British Columbia’s history, but this record was broken in 2021, and then again in 2023, when fires consumed an area three times the size of the Canadian province of Nova Scotia and the smoke travelled as far as New York City. The cause is not only global heating, which has brought hotter, dryer summers, but also the changing makeup of the forest. When logging companies clear forest, they replant it with fast-growing conifer species, but these trees are much more flammable than Canada’s diverse, native forest.

  • Caistor St Edmund, Norfolk: Deworming horses is as important as ever, but not at the expense of dung beetles – which are coming out of hibernation now

    I slide a medical spatula into George the Connemara pony’s mouth, carefully finding the interdental gap in his teeth after his incisors. He begins licking and chewing, working out if it is edible. My job is to hold it in place for at least 30 seconds to get a good sample of his saliva on the absorbent swab, which will be analysed to see if his antibodies indicate a burden of tapeworms.

    Back a decade or two, deworming horses was a routine three-monthly job in the horse-care calendar. But resistance to wormers has increased and there is growing understanding of the impact on the environment. Deworming should be targeted so that horses are only wormed if needed.

  • Hedgehogs’ habitat is shrinking, they’re vulnerable to cars, and pesticides are affecting their food supply. Here’s how we can help them pull through

    With stumpy, speedy legs, questing snouts and a fierce quiver of needles, hedgehogs are enchantingly strange, like fantasy creatures from a medieval bestiary. “It’s the nation’s favourite wild animal – every time there’s a vote or a poll, the hedgehog wins,” says ecologist Hugh Warwick, AKA “Hedgehog Hugh”, author of the Cull of the Wild and hedgehog champion.

  • Colossal Biosciences’ CEO says its work follows a ‘moral obligation’ while critics say it’s ‘tech bro’ hype that could undermine conservation

    Can and should we resurrect animal species that have been extinct for thousands of years? Such weighty, existential questions were once the preserve of science fiction but are now being played out within an unassuming brick building in a Dallas business park.

    Colossal Biosciences, valued at $10.2bn after raising hundreds of millions of dollars in funding from investors including celebrities spanning from Tiger Woods to Paris Hilton, has provoked a stampede of acclaim as well as denunciation after announcing last year it had made the dire wolf, a species lost from the world for more than 10,000 years, “de-extinct” via the birth of three new pups.

  • The Quapaw Nation is the only US Native community to carry out a cleanup of one of the country’s worst sites of environmental contamination

    They call this land the Laue. In the late 1800s, part of these 200 acres of grassland inside the Quapaw Nation were allotted to tribal citizen Charley Quapaw Blackhawk. After forcing dozens of tribes into Indian territory before the civil war, the US government then parceled out reservations and property to individual members. It was part of the government’s attempt to “civilize” Native Americans by turning them into private, not communal,landholders and yeoman farmers in the model of Thomas Jefferson’s ideal citizen.

    Yet, for the last century, little grew on the Laue. Half of it was buried beneath towering mounds of toxic rock known as chat piles. The waste rock, laced with chemicals, was left after miners extracted millions of tons of lead and zinc from the Tri-State Mining District, where the valuable ores stretched across Kansas, Missouri and Oklahomabetween 1891 and the 1970s. By 1983, the Environmental Protection Agency (EPA) had designated 40 sq miles that include nearly all the Quapaw Nation as the Tar Creek Superfund site, joining the EPA’s list of the most contaminated places in the country. Informally called a “megasite”, Tar Creek remains one of the largest and most complex environmental disasters in the country.

  • Mohammed Ahmed Sayed Mohammed is among those redeploying his skills for a local recycling company that is cleaning up the Nile

    At 6am, Mohammed Ahmed Sayed Mohammed steers his boat from al-Qarsaya island through Cairo’s Nile waters towards the capital’s riverside clubs. Fifteen years ago, he searched for fish. Now he hunts plastic bottles.

    “The fish fled from the plastic chokehold,” said Sayed, who has lived on the Giza island since arriving from Assiut, further south on the Nile, as a 14-year-old fishing apprentice. He never returned to his village, marrying locally and raising three children who now live alongside him with their 12 grandchildren on the island housing 200 families.
