'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."

  • Figures show domestic flower growers are expanding their market share, as the government gives sector official recognition

    British flower farmers have long resembled David faced with their own particular Goliath – the imported flower industry. More than 80% of cut flowers bought by UK consumers are shipped or flown in. However, recent figures show domestic growers are expanding their market share.

    Chloë Dunnett, the founder of Sitopia Farm, a London-based organic farm growing food and flowers, says: “Our flower sales are up 65% for the year and turnover is increasing year on year as the public and florists look for flowers that are seasonal, environmentally friendly and hyperlocal – consumer power can be very effective.”

  • The US, Russia, Iran and Saudi Arabia – some of the highest oil-producing nations and major greenhouse gas emitters – opposed the measure

    The UN has voted 141-8 to adopt a resolution backing a world court opinion that countries have a legal obligation to address climate change, with the US – which is the world’s biggest historical emitter – among the small group opposing it.

    The UN secretary general, António Guterres, said Wednesday’s general assembly vote, in which 28 countries abstained, underscored that governments are responsible for protecting citizens from the “escalating climate crisis”.

  • Phenomenon, often seen around Britain’s coast at this time of year, is caused by a combination of algae and weather

    At this time of year a sinister-looking substance can often be sighted around Britain’s coast: a frothy foam piled up along the shoreline or appearing in long ribbons offshore. People sometimes assume this foam is the result of pollution or sewage dumping. In fact it is a common natural phenomenon produced by a combination of algae and weather.

    Sea algae start to grow in April as conditions warm. The most common sort, phaeocystis, is not toxic and forms part of the marine food chain. When the algal bloom dies it leaves a brown scum of organic material with surfactant properties, which, like soap, lowers the surface tension of the water.

  • Willington, County Durham: On a fine May morning, there’s no better time to look at the stunning array of ways that bees and flowers have co-evolved to interact

    “It is a truth universally acknowledged, that a wild flower in possession of a fortune in nectar and pollen, must be in want of a pollinator,” Jane Austen might have written, had she been a botanist. All along this former railway line, on a sunny May morning, there are thousands of newly opened flowers laden with such inducements, vying for the attention of foraging bumblebees. And none delivers its pollen with such deception and violence as broom (Cytisus scoparius).

    A large bumblebee arrives, settles briefly, finds no nectar and departs, leaving a deranged tangle of stamens protruding from the petals. What happened? Poking my finger into an intact flower, to mimic the visitor, there’s an explosion of pollen as 10 stamens and a coiled stigma, confined in the boat-shaped keel petal, break free. Simultaneously, they deliver and collect pollen, with a gut-punch to the insect’s furry abdomen. Bumblebees don’t seem to mind; the trap has been tripped in almost every flower on this bush.

  • Environmental activists lock themselves to pesticide barrels in protest outside Syngenta headquarters

    More than 40 people, including Greenpeace UK’s programme director, Amy Cameron, have been arrested after a protest outside pesticide company Syngenta’s Yorkshire headquarters.

    A number of the activists locked themselves on to 15 blue pesticide barrels outside the headquarters, blocking the gates and leading to the temporary closure of the local A62. Activists had transformed a roundabout outside the front entrance into a giant hazard symbol carrying the message “Syngenta poisons nature” with an arrow pointing directly at the building. The action took place on World Bee day.

  • Global study finds wrappers, bottles and lids on shorelines of 93% of countries analysed as UN talks to tackle issue in turmoil

    Plastic food wrappers, bottles, lids and caps are by far the most common items of litter found on the world’s shorelines, a study has found.

    Researchers looked at data from more than 5,300 surveys of coastal litter to produce the first global analysis of its kind. They found the data in 355 existing studies on the subject.

  • What does a surge in ocean temperatures, compounded with El Niño, bode for the summer?

    An enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists as new data shows its ecological and environmental effects are intensifying.

    The unusual area of warm water has persisted since peaking in size during September 2025 and still stretches thousands of miles from the California coastline – more than halfway across the Pacific – affecting a vast triangle-shaped region of oceanic habitats from Hawaii to British Columbia and southward to Mexico.

  • Authorities are cracking down on rights activists fighting for Indigenous people threatened by authoritarianism, extractivism and climate breakdown

    The operation began at 9am Moscow time, but took place across all of Russia’s 11 time zones. Almost simultaneously, agents of the federal security service (FSB) raided the homes and workplaces of 17 Indigenous rights activists.

    Officers carried out searches, confiscated laptops and phones, and arrested and interrogated activists about participation in international forums. Most were let go; many have since left the country. Others remain in Russia, but will no longer speak up.

  • In the country’s north, mining has ravaged Indigenous lands and lives for decades. Is history repeating itself as renewable energy schemes arrive on their doorstep?

    In the heart of the dry tropical forest, Maria Elena Aguilar Uriana walks past towering cacti, her ancestors’ graves, and patterned clothes blowing in the wind. Her brow is furrowed, her hands fixed on her hips. She points to a former watering hole, now nothing but dust.

    “Our children are malnourished and dying,” she says. “It’s all because of the mining. It has destroyed our landscape, our homes, our lives.”
