Birdwatch October 2018

Yet again our birdwatcher Steve Jones reports lower numbers of species sighted than might be expected.

Once again October has been quiet in the numbers of birds about and new species passing through.

I was swimming most mornings at Soline/Vrboska and, as reported last month, on October 2nd I saw five common cranes passing over. For two weeks there was a regular Kingfisher visiting at Soline, and during the early part of October I was seeing regular Swallows and Swifts, seeing my last Swift on October 10th.

At the beginning of the month the Blackcaps were most prominent by sound and if you were lucky enough you might see one before it went into the undergrowth.

Here are examples of female (brown cap, pictured above) and the male (pictured below).

There was also the odd Wheatear, sometimes on the airfield but this was taken in Dol near the Sv Ana church.

As we approached mid October you probably noticed that Robins were starting to sing and they took over as being the most prominent bird. At much the same time we had several Stonechats arrive. As I see them in most Winter months I think that the odd one or two overwinter here although the bulk would move on.

In mid-October you also see more activity from birds of prey. I was seeing regular Sparrowhawk and Buzzards, and I managed a poor shot of a Kestrel near the airfield on the October 13th.

On October 23rd I saw three Lapwings, I often see them in the Spring but this was the first time I have seen them in October. On the same day saw my first returning Black Redstart and since then several are appearing all over now. Many will over winter here and leave in around March or April next year. These are pretty nondescript in the Winter and they don’t start colouring up until the Spring, try as I might I have yet to capture one on camera in breeding plumage. In the picture you can just make out the orange tail feathers. They will be often seen on buildings or walls, characteristically bobbing.

I was also beginning to see bigger flocks of finches. Mainly Chaffinch with a few Serin amongst them. What was interesting (although it may have been a bit early) was that I didn't see one Goldfinch this Autumn. I kept expecting to get more sightings of birds round and about, with the fine weather conditions, but there was next to nothing.

The most interesting thing for me this month was the arrival of Starlings. It is a common and fantastic sight in the UK when they come into roost in the evening in huge numbers. In mid-month I saw one Starling which I would not be surprised by, then 30+ a few days later. These numbers have been slowly building and I did a rough count of about 150 on October 31st. What makes this really interesting for me is that I have not picked up on these birds coming back through in the Autumn in previous years. It would be nice to find out where they are roosting at dusk ……………….. more work required in November!!

  • Exclusive: Report finds Natural England has created no new SSSIs, which protect areas from development, since 2023

    The government’s wildlife watchdog for England is failing to save nature because it has stopped giving protection to rare wildlife and habitats, according to a new report.

    No new sites of special scientific interest (SSSIs) have been designated by Natural England since 2023. SSSIs are nationally or internationally important places for rare wildlife and habitats. Without the designation, endangered species can be at risk of being lost to development.

  • One way to pay for wildlife conservation is to allow the rich to bag a few animals for high prices. But critics see this approach as an exercise in neocolonialism

    You can kill almost anything if you’re willing to pay. Big or small. Land, water or air. Ten a penny or one of the last of its kind. There’s nearly always a way, though it might not make you popular. The Niassa special reserve, a vast reservation larger than Switzerland, stretches for 190 miles along the northern rim of Mozambique, taking in 4.2m hectares of woodland and rivers. The reserve, one of the world’s largest protected areas, is home to elephants, leopards, hyenas, zebras and about 1,000 wild lions.

    That word, however: protected. It applies to some, but not all, of its animal inhabitants. Each year, a specific number are set aside for sacrifice, for the greater good. Not long ago,I joined an expedition in Niassa, with one of Africa’s top game-hunting companies.

  • ‘Stone age’ system of booking cross-border rail tickets holding back climate action by consumers, says thinktank

    Europe’s “stone age” system of booking train tickets makes it needlessly difficult for travellers to avoid polluting flights, a report has found.

    Booking equivalent train tickets is “difficult or impossible” on almost half of the EU’s busiest international air routes, analysis from the Transport & Environment (T&E) thinktank shows.

  • UK’s Rare Breeds Survival Trust says calf numbers of white park cattle last year were less than two-thirds of 2022 level

    An ancient breed of cattle whose ancestors are thought to have accompanied the Celts as they were pushed to Britain’s fringes by the Romans has been designated as urgently at risk by a UK conservation charity.

    Publishing its 2026 watchlist on Tuesday, the Rare Breeds Survival Trust moved white park cattle to its “priority” category as new calf numbers sank last year to less than two-thirds of their 2022 level.

  • The country is seeing an increase in human-wildlife conflict as the number of megafauna, including rhinos and tigers, grows. But there are efforts to tackle the problem around Chitwan national park through education and training

    The tourists lining the steep embankment buzzed with excitement, phones out, snapping away in the twilight as a wild Indian rhinoceros grazed below the Nepali village of Sauraha. Climbing to the main street, the rhino ambled down the middle of the road.

    Local people warned tourists to give it plenty of space. All manner of wheeled vehicles slowed, then passed. The rhino turned its horn at a cyclist passing too close, triggering gasps from the assembled crowd.

  • Knotbury, Staffordshire: A truly special dawn, when last night’s ice lingered on everything, and I was joined by no fewer than six ring ouzels

    As I drove to this tiny moorland hamlet, the dawn sky looked so grey that I imagined it must have 100% cloud cover. Actually, there was none, and as the blue slowly crept in overhead, I could see that frost was everywhere.

    I also realised that there was no breeze and every sound seemed distilled, so I stopped by the first farm to record my blackbird. He has mastered the sweetest imitations of displaying golden plovers, but this was my first chance to capture them. And there he was, doing his plover notes, but throwing in snippets of curlew as extras, and when he stood in profile at the roof apex, singing, bill wide, throat feathers spiked against the heavens, I knew the morning would be magical.

  • Sarah Finch is among six recipients of the Goldman Environmental prize, awarded to honour grassroots activists around the world

    The woman whose campaigning set a legal precedent in the UK that stopped thousands of tonnes of greenhouse gas emissions has been awarded one of the world’s most prestigious environmental prizes alongside five other women from around the globe.

    A supreme court ruling in a case brought by Sarah Finch has been cited in decisions against new oil concessions in the North Sea, the UK’s first new deep coalmine for 30 years and even plans for new large-scale factory farms.

    Iroro Tanshi, a Nigerian conservation ecologist who launched a successful, community-led campaign to protect endangered bats from human induced wildfires;

    Borim Kim, a South Korean activist who won the continent’s first successful youth-led climate litigation, finding her government’s climate policy to be in violation of the rights of future generations;

    Alannah Acaq Hurley, a leader of the Yup’ik Indigenous people led a campaign that stopped what would have been the continent’s largest open-pit mine, in Alaska’s Bristol Bay region;

    Yuvelis Morales Blanco, a youth activist who mobilised others in her Afro-descendant community in Puerto Wilches against two drilling projects, preventing the introduction of commercial fracking into Colombia;

    Theonila Roka Matbob, of Papua New Guinea, whose campaign forced Rio Tinto, the world’s second-largest mining company, to sign an agreement to address devastation caused by its Panguna mine.

  • Kerbside wheelie bins have been used in Australia since the 1980s but the recycling rate is stuck at 44%. Will another recycling bin make a difference?

    There’s no garbage truck in Kamikatsu.

    Instead, the Japanese town’s 1,400 residents take their waste to the local recycling centre, or “Gomi station”, and sort it themselves into more than 40 different categories.

  • As the rising number of vessels in the icy waters increases the risk of environmental disaster, scientists are scrambling to find potential solutions

    Last winter, inside the subarctic Churchill Marine Observatory in Canada, scientists embarked on an experiment they hoped would result in a gamechanging remedy for polluted Arctic waters. They released130 litres of diesel into an ice-covered pool filled with raw seawater pumped in from Hudson Bayand added oil-eating microbes. The technique had been used successfully during the Deepwater Horizon oil spill in the Gulf of Mexico, and the scientists wanted to see if they could break down oil in colder waters.

    The microbes were sluggish in response and the population showed little change after the first three weeks, says Eric Collins, a microbiologist at the University of Manitoba in Winnipeg, who led the project. But that did not last. “When we went back eight weeks later, we saw that there was a big change,” Collins says. “One particular bacterium grew to a very high abundance in the tanks and it was clear that it was feeding on the oil.” But two months is too long to wait should an oil spill occur. Time is of the essence.

  • Sarah Finch’s fight against drilling led to a landmark ruling on fossil fuel emissions – and a leading environmental prize

    It started with a notice in the local newspaper and ended with winning one of the world’s most prestigious environmental prizes. In 2010, Sarah Finch was flicking through the local planning notices when one caught her eye: a proposal to drill for oil at Horse Hill in Surrey, just outside Crawley, over the border in West Sussex, 6 miles (10km) from her home.

    Surrey is not the kind of place one expects to find the oil industry. It’s a county of little villages, farms, woods and commuter railway stations. Its semi-rural landscape stretches off towards the horizon in a typically English green patchwork. It is difficult to envision it littered with nodding donkey pumpjacks and gas flares.

  • Nova studija utvrdila je značajnu povezanost između prenatalnog propisivanja često korištenih lijekova i rizika od poremećaja iz autističnog spektra (ASD) kod djece.

  • Prema rezultatima nove studije, čini se da veći unos natrija utječe na epizodno pamćenje, vrstu pamćenja koja se koristi za prisjećanje osobnih iskustava i specifičnih događaja iz prošlosti. Valja istaknuti, da ovaj učinak – koji bi mogao uzrokovati da netko zaboravi bilo što, od mjesta gdje je parkirao automobil do prvog dana škole – pojavio se uglavnom među muškarcima.

  • Infekcije uzrokovane bakterijama otpornim na antibiotike teško je liječiti i odgovorne su za preko 2,8 milijuna infekcija i više od 35.000 smrtnih slučajeva u SAD-u svake godine. Nova studija izvještava da bi lijek koji se koristi za snižavanje povišenog krvnog tlaka mogao biti i osnova obećavajućeg novog liječenja meticilin-rezistentnog Staphylococcus aureusa (MRSA).

  • Nedavna objavljena studija procijenila je učinke dnevne konzumacije naranči (400 g dnevno) tijekom 4 tjedna na profile serumskih lipida kod pacijenata s MASLD-om. MASLD, ranije poznat kao nealkoholna masna bolest jetre (NAFLD), stanje je usko povezano s metaboličkim sindromom, visceralnom pretilošću i dijabetesom tipa 2. Svrstava se među vodeće uzroke morbiditeta i transplantacija povezanih s jetrom diljem svijeta, a promjena načina života i intervencija u prehrani ostaju najučinkovitije terapijske strategije.

  • Rizik od raka povećava se s godinama i često je agresivniji i teži za liječiti kod starijih osoba. Novo istraživanje znanstvenika s Fox Chase Cancer Center, sugerira da se melanom ponaša drugačije s godinama. Podaci su pokazali da je širenje raka bilo najniže kod mladih miševa, vrhunac kod miševa srednje dobi, a opalo kod vrlo starih miševa.

  • Novo istraživanje otkriva kako kratka seansa finske saune mobilizira imunološki sustav u roku od nekoliko minuta, nudeći nova saznanja o tome kako izloženost toplini može utjecati na ljudsko zdravlje.

  • Sve veći broj gljivica postaje otporan na lijekove, što predstavlja ozbiljan rizik za pacijente s oslabljenim imunološkim sustavom. Stoga znanstvenici pozivaju na djelovanje protiv gljivica otpornih na lijekove. Plan uključuje pet koraka - podizanje svijesti, nadzor, sprječavanje i kontrolu infekcija, optimiziranu upotrebu i ulaganja.

  • U nedavnoj studiji objavljenoj u stručnom medicinskom časopisu BMJ Open, znanstvenici su revidirali točnost, referenciranje i čitljivost pet popularnih chatbotova vođenih umjetnom inteligencijom (AI) kako bi istražili kako su odgovorili na zdravstvene upite u područjima sklonim dezinformacijama. Studija je koristila 250 upita u pet kategorija sklonih dezinformacijama, a rezultate su procijenila dva stručnjaka za predmetnu materiju u svakoj kategoriji koristeći unaprijed definirane kriterije.

  • Nedostatak sna već je dugo poznat po tome što slabi imunološki sustav. Sada su američki znanstvenici s UF Health Cancer Institute došli do zapanjujućeg otkrića, naime, izgleda da crijevna mikrobiota potiče promjene u imunološkom sustavu uzrokovane kroničnim nedostatkom sna. Ove promjene potiču napredovanje raka, remete cirkadijalni ritam i slabe učinkovitost kemoterapije.

  • Lijekovi koji ciljaju proteine ​​beta amiloida u mozgu vjerojatno nemaju klinički značajne pozitivne učinke, a povećavaju rizik od krvarenja i oticanja mozga, otkrila je analiza 17 studija. Inače, osobe s Alzheimerovom bolešću imaju visoke razine proteina poznatog kao beta amiloida u mozgu, koji se može otkriti prije početka simptoma, ali njegova uloga u napredovanju bolesti nije sigurna. Razvijeni su lijekovi za uklanjanje tih proteina iz mozga, pod teorijom da bi to spriječilo ili usporilo napredovanje bolesti.
