Ptice prognostičarke vremena

Čovjek i spoznaja vremena (meteorologija) koračaju ruku pod ruku od pamtivijeka do današnjih dana kaže Hvaranin Marko Vučetić, široj javnosti poznat po svom djelovanju u (Državni hidrometeorološki zavod - DHMZ-u), odnosno Odjelu za agrometeorološke informacije. Sa suprugom Višnjom autor je vrijedne knjige "Vrijeme na Jadranu", što je ponajprije meteorološki priručnik za nautičare, međutim, ugledni meteorolog je tijekom svoje dugogodišnje karijere napisao niz stručnih i znanstvenih radova u kojima se, osim čisto fizičkim zakonitostima u atmosferi, bavio ljudskim opažanjima, iskustvima, tradicijom, pa onda i pučkim izrekama koje su iz toga proizašle.

Jedna karakteristična za Otok sunca je "Sv. Ivon - hod' iz poja von", koja se spominje za blagdan sv. Ivana Krstitelja (24. lipnja), a hoće reći da dolazi vrijeme ljetnog krijesa, da se težaci do žanjanja lavande trebaju odmoriti. Druga je "Svieti Antuonij Opat – vazmi motiku i puoj kopat" (17. siječnja), u smislu da je vrijeme odmora nakon berbe maslina prošlo te da stiže sezona radova u polju (gnojidba, rezidba, priprema zemlje za proljetnu sjetvu...). Ima ih još, npr. "Sv. Fabijon kreši uru don" (20. siječnja), što znači da ljudi imaju sat vremena više za lavur te "Kandelora - zima fora, svi kosići priko mora. Za njon gre svieti Blaž i govori da je to laž" (2. veljače).

Dakle, čuli su od svojih nona i nonotih da je zima praktično iza nas, ali ima tu i pinku skepse, jer se još koji dan treba ložiti vatru u kućama, a za izlaska u mjesto višeslojno se odjenuti. Zanimljiva je i ona "Poslije svietog Matija svaka ptica propiva" (24. veljače), pa bismo mogli konstatirati da i ptice na neki način mogu biti prognostičarke vremena. Nekad nagovještavaju zime, nekad toplija vremena.

Dosta smo slušali o ždralovima, rodama, lastavicama..., u dolini Neretve o svadbenom plesu lisaka, o čemu zasigurno puno više zna gospodin Vučetić. Nas je zanimalo koje ptice još na njegovom otoku nagovještavaju promjenu vremena?

▪ Pa primjerice možemo spomenuti gorsku pastiricu (Motaclia cinerea), palčića (Troglodytes troglodutes), galeba klaukavca (Larus cacchinans) i vodomara (Alcedo otthis).

Kad pastirica i palčić, kojeg na Hvaru nazivaju još carić ili strižić, dolete s kopna na naše otoke onda zapravo najavljuju hladni val, loše i ružno vrijeme.

Slično je i sa preletnicom šljukom (Scolopax rusticola) za koju vrijedi ona 'Šljuka na škoj sleti kad Zagora zaledi', a Hvarani imaju i tog svog galeba.

Kad se ta opjevana ptica pojavi na akroteriju povijesnog Arsenala onda je to znak skorog grubog vremena. Oni to najčešće poprate riječima 'Kalebi u portu - nevera u kulfu', no hoće li uslijediti jugo ili bura to je već druga stvar – objašnjava nam Vučetić.

A mitsku sagu o vodomaru (Alcedo atthis) baš detaljno opisao je u svom znanstvenom radu "Vrijeme i klima Jadrana u antičkih pisaca", dovodeći ga u vezu sa zimskim maestralom, odnosno Alkioninim danima. Riječ je o ptici čiji je gornji dio tijela zelenkastomodar, a donji smeđecrven, koja živi uz vodu hraneći se ribom i sitnim vodenim životinjama. Uz more tuče kljunom po račićima, pa ga stoga na Braču nazivaju kovoc, a u Starome Gradu – Farosu kovačić. Gnijezdi se zimi u zemlji strmog stijenja, pa odatle i neki toponimi kao što je Punta kovača kod Podstina u Hvaru ili ona kod Solina na otočiću sv. Klement (Pakleni otoci).

No, što su to Alkionini dani?

▪ Usred zime da more bude mirno, bonaca k'o uje, malo je vjerojatno, ali ipak moguće. To je čudo koje se oduvijek pripisivalo volji bogova. U mitskoj priči starih Grka glavnu ulogu ima Alkiona, a njezina velika ljubav biva prekinuta pogibijom brodolomca Tesalije Keika. Kada je to saznala i krenula prema moru oboje su preobraženi u ptice – vodomare. Bogovi prema zaljubljenom paru bijahu velikodušni pa su odlučili da u vrijeme gniježđenja vodomara, oko zimskog suncostaja, nad morem vlada tišina, koja može potrajati dva tjedna. Otuda i njihova povezanost sa zimskim bonacama, koje antički Heleni nazivaše Alkionini dani ili alkionidima – pripovijeda nam naš sugovornik i ističe da je vodomar stoga simbol spokojstva i mirnih mora.

Kod nas je, kako dodaje, s tim u svezi povezana iskustvena činjenica o zimskom maestralu. Takvo vrijeme zimi ne traje dugo (najčešće tri dana), međutim, tu se zapravo radi o zmorcu – vjetru unutar obalne cirkulacije, u ovome slučaju od mora prema kopnu koji nastaje za vrijeme stabilnog vremena. Upravo zato usred zime ni ne može dulje potrajati i najčešće je predznak skorog juga, dakle, pogoršanja vremena. Svojedobno su dani sa zimskim maestralom imali poseban status kod dalmatinskih ribara i moreplovaca napose u doba jedrenjaka, što bi značilo da bi se pomnijim istraživanjem i u nas moguće pronašla veza s alkionidima.

  • Conservationists say cherished creatures such as whales, dolphins and seabirds are being killed in large numbers by fishing tackle

    Thousands of Britain’s most charismatic and protected marine wildlife, including whales, porpoises, dolphins, seals and seabirds are being killed as “collateral damage” by fishing vessels every year, according to the first-ever analysis of bycatch data.

    The analysis, by the Wildlife and Countryside Link, a coalition of voluntary conservation groups, reveals the devastating toll bycatch, the accidental capture and killing of non-target species by fishing vessels, is having on marine species.

  • Crops and flowers rely on them for survival, but wild bees are declining – and crucial nutrients will go missing from our diets as a result

    There are few ways in and out of Nepal’s Jumla district. The Karnali highway, considered one of the world’s most dangerous roads, provides the only land link, splicing through the Himalayas to connect Jumla’s terraced valleys to the rest of the country. As such, the 120,000 people that live there are almost entirely self-sufficient, with most of them eating and selling what they grow.

    It’s a tenuous existence, plagued by food insecurity and malnutrition. In recent years, local beekeepers have bemoaned languishing hives and dwindling honey production, observing that roughly half of their bees seem to have vanished over the past decade. These concerns, however, ignore an even more insidious impact.

  • Greenpeace calculates that wealthiest contribute nearly $1tn of damage a year with ownership-based emissions

    Ultra-wealthy people zooming across the world on their private jets, lounging on yachts and conspicuous by their Instagrammable consumption are among the most easily identified individual culprits when it comes to the climate crisis – but new research argues that it is not just their heady lifestyles to blame, but also their bank accounts.

    Through their ownership of companies and private financial and physical assets, from oil producers to property developments, the super-rich are responsible for an outsized slice of the greenhouse gases that are overheating the planet. The top 1% of people by wealth, through their shareholdings and investments, control about a quarter of global annual emissions in total.

  • The 700 projects include wind and solar farms, battery storage, gas and hydro plans

    More than half the renewable energy projects needed to meet the government’s clean power targets by 2030 are now able to plug into the electricity grid after years of delay, according to the system operator.

    The National Energy System Operator (Neso) has offered more than 700 clean energy projects in Great Britain a grid connection date since the start of the year, after a two-year process to unblock a bottleneck that threatened to delay projects into the 2030s.

  • Targeted vaccination and improved testing planned as part of drive to eradicate disease by 2038

    Cattle will be vaccinated against tuberculosis from 2030 as a “gamechanging” part of a new strategy to drive eradication of the disease in England by 2038. In parallel, the last badger culls are expected to end by 2029, with vaccination of badgers expanded.

    More than 20,000 infected cattle are slaughtered each year, costing taxpayers £100m and inflicting a heavy toll on affected farmers’ livelihoods and mental health. Mass culling of badgers began in 2013 and has killed about 250,000 animals, at a cost of about £60m.

  • Strawberry Hill, Bedfordshire: After an evening round the campfire, we head into the wonderfully, chaotically alive scrub, to hear the headline act

    “Now I walk in beauty / Beauty is before me”. Earlier this evening we learned the simple melody to this Navajo prayer, and sang it as a round in the hawthorn clearing, adding our voices to the chorus of chiffchaff, blackcap and garden warbler. Afterwards we sat for a few moments, listening, newly aware of the beauty before us. Across the meadow, a cuckoo began to call.

    Now night has fallen, and all is silent as we follow a narrow track through scrub and young woodland on the 150-hectare Strawberry Hill Wildlife Trust reserve. Our music around the campfire was merely a warm-up to an evening of Singing With Nightingales, and tonight’s event is part of Exeter University’s research into the effects of nature connection on chronic pain.

  • Exclusive: Sir Paul Marshall’s climate views and those broadcast on GB News said to be ‘in direct opposition’ to those of Church of England

    The co-owner of GB News, a British TV channel accused of broadcasting climate change denial, has donated £28m to influential Church of England institutions that support climate action.

    This raises “serious questions”, say Christian leaders, given that Sir Paul Marshall’s views on the climate crisis and those frequently broadcast on the TV channel are “in direct opposition” to the Church of England, which believes that “responding to the climate crisis is an essential part of our responsibility to safeguard God’s creation and achieve a just world”.

  • As the US shuts its doors to most refugees, there’s little hope of a new system to help those forced from home by climate impacts

    Millions of people around the world are having their lives upended by floods, storms and heatwaves worsened by the climate crisis. Those forced to flee their home countries, however, are finding that the door to the US is more firmly shut than ever.

    Neither US nor international law recognizes environmental hazards, such as climate-related displacement, as a valid cause to claim asylum or gain entry through other migration pathways, despite the mounting toll of disasters caused by an overheating planet.

  • US energy secretary Chris Wright featured in seminars to judges when he was a fracking executive

    As cities and states sue big oil for billions in damages over allegations that it covered up the dangers of its products, rightwing organizations are attempting to discredit the wave of litigation. They claim the lawyers behind it are teaming up with an environmentally focused legal education non-profit to bias federal judges against oil companies.

    But it is actually fossil fuel-backed organizations that are attempting to sway the judiciary in their favor, one of those law firms is countering. Evidence of this includes judicial seminars hosted by one such group featuring pro-industry speakers such as the current energy secretary, Chris Wright, in his former occupation as a fracking executive.

  • Pacoima is hemmed in by highways and heavy industry, and its residents are fighting pollution with hyperlocal air quality monitoring

    Jose Luis Salas looks up at the ladder. “Are you ready?” he asks Shance Taylor, an environmental project manager who’s holding a white container, about the size of a shoebox, covered with wires and numbers.

    Taylor nods and climbs up to reach the side of Salas’s tidy house in Pacoima, a neighborhood in Los Angeles’s north-east San Fernando valley. The curious box in their hands is known as Aeroqual sensor – part of a community air-quality monitoring program run by Pacoima Beautiful, a local environmental group.
