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."

  • Study of Channel finds levels of toxic Pfas in Solent at 13 times safe limits in some places, with much coming from treated sewage

    Scientists have found high levels of toxic Pfas, or “forever chemicals”, in soil, water and throughout the marine food chain in the UK’s Solent strait, including at protected environmental sites, according to a new study.

    In some samples, pollution was 13 times the safe threshold for coastal waters. Others, which were below legal limits for individual chemicals, failed tests for combined toxicity.

  • Rush to develop fossil fuel infrastructure in Canada collides with laws meant to protect endangered species

    Environmental groups in Canada fear endangered orcas could become a casualty of Mark Carney’s push for a new oil pipeline, as the rush to develop fossil fuel infrastructure collides with laws meant to protect threatened species.

    The decades-long tragedy of the critically endangered southern resident orcas has become emblematic of an ecosystem in crisis. But fishermen, whale-watching companies and the marine transport industry have long feuded over who bears the most blame.

  • Rising demand for exotic pets is pushing many gibbon species to extinction, with their strong family bonds making them especially vulnerable to the brutal trade

    It is a cool morning in Thailand’s hilly north, and a wildlife officer sits on the veranda of Omkoi wildlife sanctuary’s office. On her lap is a wide-eyed infant primate dressed in baby clothes. Not unlike a human baby, he kicks and waves excitedly. Most of his dark skin is covered in dense white fur, except for his face and the palms of his hands.

    “We call him Chokdee,” the officer says. “It means ‘good luck’.”

  • Snitterton, Derbyshire: I’ve had some glorious early mornings admiring the abundance of these much-loved flowers

    This spring has specialised in very specific kinds of abundance. In February it was snowdrops in extraordinary numbers, but last month it was dandelions. My most exulted sighting came as I drove out of upper Dovedale when, from the corner of my eye, I caught a blanket of gold running over the slope.

    The flowers held the foreground before the eye travelled onwards to Sheen Hill in Staffordshire. We overuse the word “carpet”, but in this instance it was appropriate. Each bloom was about the same height as all its neighbours, and if you eliminated gaps in colour by getting down face to face with the flower heads, then the whole land was turned into a single glorious sunshine hue.

  • Caistor St Edmund, Norfolk: Firebugs congregate in large numbers to feast and mate – and this is the first time we’ve known their revelry on the farm

    At this time of year the farm is a popular spot, with people strolling, horse riding or picnicking from dawn till dusk. One of the unexpected joys of opening up public access is the extra pairs of eyes. A broken fence or fallen tree is noticed almost immediately; an otter is spotted slipping into a stream at first light. Recently, Laura, a regular dog walker and keen photographer, shared something new.

    Congregating on the sunny side of an old lime tree is a colony of firebugs. There are 50 or so, clustered together, like flames flickering up the trunk. Each is nearly a centimetre long, with ember-bright red backs marked by bold, symmetrical black shapes. These aggregations, typically on lime or mallow, are for mating and feeding. A firebug eats seeds, aphids or even its dead relatives, sucking out moisture with its proboscis.

  • Exclusive: Commission says alert would trigger coordinated international response that could help avoid millions dying

    The climate crisis should be declared a global public health emergency by the World Health Organization, or millions more people will die unnecessarily, leading international experts have said.

    The independent pan-European commission on climate and health, which was convened by the WHO, concluded the climate crisis was such a worldwide threat to health that the WHO should declare it “a public health emergency of international concern” (Pheic).

  • Despite the ban on disposables, waste professionals say the mountain of discarded devices is a £1bn-a-year issue

    It is 2pm and Ana, 47, has just started the afternoon shift at the Suez recycling plant near Birmingham city centre, standing beneath a sign reading “Non-ferrous sorting station” with a bucket of vapes in front of her. Sorting and dismantling them is part of her job as a site operative.

    Recycling them is not simple. Each bucket holds between 40 and 50 devices, and over the course of a shift, she gets through about half a bucket. Using a hammer, she has to smash each vape open, pry out the batteries and separate each component into a different container.

  • As new settlers clear their forest habitat, the apes are coming into conflict with humans. But simply moving them to another part of the forest may not be the answer

    The banana skins were an ominous sign. As was the branch that had been broken off to get to the fruit. Had Edi Ramliwalked into the forest, he might have seen scattered balls of bark that had been ripped off trees, chewed like gum, then spat out. It takes a powerful jaw to do that. Closer to Edi’s home, there was an intricate construction of bent and broken branches high in a tree. The nest.

    It was October, the fruiting season. The pile of half-eaten bananas was less than a minute’s walk from where Edi and his family slept. He felt nervous. He got on with his day. He picked sweetcorn and sold it at the market. He bought a carton of chocolate milk and biscuits for his grandson. He and his wife, Siti Munawaroh, ran the farm with their three adult children. They prepped the land, sowed seeds, tended crops. Survival depended on what they could grow.

  • Like many informal settlements, communities that have sprung up on the edges of Ayacucho in the Andes are on the frontline of extreme weather events

    In December 2009, a late‑afternoon storm unleashed torrential rain over Ayacucho, in Peru, hitting poor hillside neighbourhoods hard. The deluge overwhelmed drainage systems, turning streams into lethal flows of mud, stones and debris that flooded houses and streets and trapped drivers at a busy junction.

    Ten people died, 18 were injured, and 530 houses were destroyed or damaged, according to a government inquest. “It was a disaster,” recalls Edgar Castro, a leader in Ayacucho’s largest informal neighbourhood, Mollepata.

  • With Israel blocking imports of building materials, those rebuilding in Gaza are recycling ruins to make new homes

    It is difficult to see through the dust inside the cramped, low-roofed tent on the eastern edge of Khan Younis. Ibrahim al-Aloul works alongside four others, with a piece of fabric tied over his mouth and nose as his only shield against the toxic grey powder as he sifts and grinds.

    Outside, a skinny donkey waits with a cart to carry the finished product to the next tent along, where it will be mixed with gypsum, calcium and binding agents before being bagged in flour sacks and sold.
