'Gulls in the harbour - storm at sea'

Birds as weather forecasters

 Mankind has had an understanding of the weather and meteorology from time immemorial up to the present day, according to Marko Vučetić from Hvar, well known to the Croatian public for his work in the Agrometeorological Information Department at the Croatian Meteorological and Hydrological Service.. Marko and his wife Višnja are co-authors of the invaluable book 'Vrijeme na Jadranu, meteorologija za nautičare', a guide to meteorology for sailors published by Fabra d.o.o., 2013. Besides this, in the course of his long and distinguished career as a meteorologist Marko has published numerous professional and scientific works, covering not only the purely physical laws of the atmosphere, but also the human perceptions, experiences, traditions and popular expressions which have arisen from them.

Hvar Island has several typical dialect sayings related to the weather and the seasons, such as 'Sv. Ivon - hod' iz poja von', which translates literally as 'St. John - come out of the fields', and means that from St. John the Baptist's feast day (24th June) farmers should take a break until it's time to harvest the lavender a few weeks later. 'Svieti Antuonij Opat – vazmi motiku i puoj kopat' - 'St. Anthony the Abbot - pick up your mattock and start digging': this means that from the saint's feast day on 17th January, the period of rest following the end of the olive harvest is now over and it's time to resume work in the fields, fertilizing, pruning and preparing the soil for the spring planting. 'Sv. Fabijon kreši uru don' - 'St. Fabian - the day has an extra hour': from the feast day on 20th January, work in the fields lasts longer.

'Kandelora - zima fora, svi kosići priko mora. Za njon gre svieti Blaž i govori da je to laž' means 'The feast of Candlemas (2nd February) marks winter's end, all the songbirds are arriving across the sea, but then comes St. Blaise (3rd February) who says it's all a lie'. There are various versions of this saying, warning that winter is not necessarily over at the beginning of February, the weather can suddenly still turn for the worse, however mild it seem at that point. The saying 'Poslije svietog Matija svaka ptica propiva' means 'After St. Matthew's feast day (24th February) all the birds burst into song', marking the start of spring.

Birds, in their way, can be weather forecasters, sometimes foretelling cold weather, sometimes warmer.

We hear a lot about cranes (Grus grus), storks (Ciconia ciconia), swallows (Hirundo rustica) as heralds of changes in the seasons, and especially the coots' 'wedding dance' in the Neretva valley which marks the end of winter and the start of spring. So which birds does Marko Vučetić consider significant as weather forecasters on Hvar? These are the ones he highlighted.

Grey wagtail, wren, gull and kingfisher

"As examples we can cite the grey wagtail (Motacilla cinerea), wren (Troglodytes troglodytes), yellow-legged gull (Larus cacchinnans michahellis) and kingfisher (Alcedo otthis). When the grey wagtail and wren arrive on our islands from the mainland, they herald a cold spell with really bad weather.

Similarly when the Eurasian woodcock (Scolopax rusticola) migrates to the islands, it's a sign of bad weather on the mainland, hence the folk saying: 'Šljuka na škoj sleti kad Zagora zaledi', 'The woodcock lands on the island when the hinterland turns icy'.

Hvar islanders have their own weather-forecasting bird in the sea-gull.

When this well-known bird settles on the acroterion of Hvar's historic Arsenal on the waterfront, it is a sure sign of imminent bad weather. There is a folk saying describing this: 'Kalebi u portu - nevera u kulfu', - 'Gulls in the harbour, storm at sea', but whether the accompanying wind will be a fierce south 'Yugo' or north 'Bura' remains to be seen."

Marko Vučetić has described in detail the mythical saga of the kingfisher (Alcedo atthis) in his scholarly work 'Vrijeme i klima Jadrana u antičkih pisaca' - ['Weather and climate on the Adriatic in the writers of Antiquity'], linking this colourful bird with the winter maestral wind, or rather with the phenomenon known as 'Alcyone's days'. Kingfishers live close to water and feed on fish and small aquatic organisms. At the seaside they use their long beaks to batter little crabs, which has earned them the name of kovoc (blacksmith) on Brač and kovačić (little blacksmith) in Stari Grad on Hvar. In winter they nest in the ground on steep rocks, which has given rise to toponyms such as Punta kovača near Podstine in Hvar Town and near Soline on the islet of sveti Klement in the Pakleni Islands off Hvar.

So what are 'Alcyone's days'?

In Marko Vučetić's words: "In winter it is not often that the sea is totally calm and smooth as oil - known as bonaca k'o uje in local dialect - but it can happen. When it does, it is a marvel which from time immemorial has been attributed to the gods. In Ancient Greek mythology the leading role in this is attributed to Alcyone whose deep love for her husband Ceyx, King of Trachis, was shattered when he died in a shipwreck. When she heard Ceyx had died, in her grief she headed into the sea. The gods took pity on the enamoured couple and turned them into kingfishers, generously arranging that when the kingfishers were nesting, around the time of the winter solstice, the sea would become totally quiet, and could remain so for about two weeks. This is the link between kingfishers and the calm sea in winter, which the Ancient Greeks called 'Alcyone's days', [giving rise to the English name 'Halcyon days'].

In our region, this winter calm weather is related to the experience of the winter maestral wind. Such weather does not usually last long - most often just three days - and it is in fact a sea breeze, a wind within the coastal ambit, which in this case circulates from the sea towards land when the weather is stable. As it cannot last in winter time, it is most often the precursor of the Jugo (south wind), bringing with it bad weather. Once upon a time the winter maestral had special significance for Dalmatian fishermen and seafarers, especially in the age of sailing boats, which would mean that careful research might reveal that we too may have our own links with the Alcyone Days."

  • Volunteer workers say increasing case numbers and dozens of dead birds raise fears spread is wider than recorded

    Members of the public and charity volunteers are working to contain a suspected outbreak of bird flu among swans in the Thames Valley, amid signs that confirmed cases are continuing to rise.

    Since October, 324 cases of bird flu in swans have been recorded by the Animal and Plant Health Agency (Apha), which is sponsored by the Department for Environment, Food and Rural Affairs (Defra). Of these, 39 were recorded in the first four weeks of 2026 alone.

  • With some of Ukraine’s most valuable biodiversity sites and science facilities under occupation, experts at Sofiyivka Park in Uman are struggling to preserve the country’s natural history

    In the basement laboratory of the National Dendrological Park Sofiyivka, Larisa Kolder tends to dozens of specimens of Moehringia hypanicabetween power outages. Just months earlier, she and her team at this microclonal plant propagation laboratory in Uman, Ukraine, received 23 seeds of the rare flower.

    Listed as threatened in Ukraine’s Red Book of endangered species, Moehringiagrows nowhere else in the wild but the Mykolaiv region of Ukraine. Of those 23 seeds, only two grew into plants that Kolder and her colleagues could clone in their laboratory, but now her lab is home to a small grove of Moehringiaseedlings, including 80 that have put down roots in a small but vital win for biodiversity conservation amid Russia’s war with Ukraine.

  • A US judge will decide if, as research suggests, a chemical tyre additive is harming endangered fish species

    Last week, a district judge in San Francisco, California, presided over a three-day trial brought by west coast fishers and conservationists against US tyre companies. The fishers allege that a chemical additive used in tyres is polluting rivers and waterways, killing coho salmon and other fish. If successful, the case could have implications far beyond the United States.

  • The US president tried to kill offshore wind projects – now four are back under construction

    Construction has resumed on four offshore wind mega-projects after they survived a near-fatal attack by Donald Trump’s administration thanks to rulings by federal judges. These are being seen as victories for clean energy amid a wider war being waged on it by the Trump administration.

    The windfarms are considered critical by grid planners as America faces an energy affordability crisis. Together, the four projects will contribute nearly five gigawatts of energy to the east coast, enough to power 3.5m homes.

  • After stories revealed high levels of contamination in neighborhood around factory processing US toxic waste, government announces sweeping array of tactics

    The Mexican government has announced it will pursue a sweeping array of tactics to combat industrial pollution, from $4.8m in fines against a plant processing US hazardous waste to the rollout of a new industrial air-monitoring system, following investigations by the Guardian and Quinto Elemento Lab, a Mexican investigative unit.

    Those stories revealed high levels of heavy-metal contamination in the neighborhood around the factory, Zinc Nacional, in the Monterrey metropolitan area, and showed the broader extent of industrial pollution in the region, linked to Monterrey’s role in manufacturing and recycling goods for the US market.

  • Bridport, Dorset: Paths became streams and new islands appeared as the River Brit burst its banks

    We were warned that rain was coming – and so it did, barrelling down all night, falling through the darkness on to ground that was already saturated. By the time it was light, the rivers through Bridport had risen and spread across the floodplain, splicing into a broad, brown rope of water twisting to the harbour at West Bay.

    Contemptuous of its banks, the River Brit was running noisily across meadows, forming new lakes where herring gulls sat floating on its muddy surge. Water went straight through the allotments, sending plastic pots bobbing like buoys against the boundary fence.

  • Events such as Storm Chandra take a terrible toll on ecosystems, but nature can be part of the solution for mitigating flood waters

    “The flood waters are only good for scavenger species,” says Steve Hussey, searching hard for a silver lining to last week’s deluges brought by Storm Chandra. When the waters recede, crows and ravens will feast on the carrion of hedgehogs, dormice and other small animals unable to escape the rising water, he says.

    “It sounds very apocalyptic, doesn’t it?” says Hussey, a communications officer with the Devon Wildlife Trust.

  • Honduras is one of the most dangerous countries for environmentalists – and the release of Juan Orlando Hernández has reinforced its ‘crisis of impunity’, say critics

    When Donald Trump announced that he would pardon the former Honduran president Juan Orlando Hernández, only the second world leader to be convicted of drug trafficking, Anna*, an environmental defender, was shocked.

    In 2022, Hernández, also known as JOH, was extradited to the US and later convicted, along with his brother, on drug trafficking and weapons charges. He was sentenced to 45 years in prison for conspiring to smuggle more than 400 tonnes of cocaine into the US, becoming the first Honduran head of state to be tried and sentenced abroad for running a narco state. He was also accused of grave human rights violations.

  • Inspired by YouTube creators, some people are limiting beef to a handful of ‘feast days’ a year to cut their climate impact

    “I love beef,” says Vlad Luca, 25. But unlike most other self-proclaimed steak lovers, Vlad eats it only four times a year, on designated “beef days”.

    The “beef days” phenomenon has been popularised by the brothers John and Hank Green, known collectively as vlogbrothers on YouTube. John, 48, is better known for his YA fiction, including The Fault in Our Stars, while Hank, 45, is a self-described science communicator and entrepreneur.
