Hvar's birds declining?

Are Hvar's bird numbers dwindling?

When we first moved to our house in Šiberija in 2004, we were delighted to discover a family of little owls nesting in the garden,and every evening at dusk we were treated to the antics of the young ones learning to fly.  They were as curious about us as we were about them and they would sit on low branches watching us in between their circuits of the garden.  Sadly they never returned to nest here and it is several years now since we have even heard one.  We do of course hear the Scops owls and the occasional tawny owl but not as often or as close by as we used to.

Other not infrequent visitors were hoopoes, golden orioles, blackcaps, shrikes, turtle-doves and nightingales (which several years running used to take up residence in a bush near our house and sing almost non-stop for 48 hours - I went off nightingales a bit at that point!).  We also used to hear cuckoos and nightjars in the fields beyond the old Hvar Road but it is several years now since we have heard either so close by.  We have also missed the regular calling of hoopoes and golden orioles in the distance.  There seems to have been a marked decline in the flocks of bee-eaters which used to burble about above us so much, but we were really pleased to see and hear about half-a-dozen near Mlin above the harbour yesterday.  Still nothing like the large numbers we were used to though.

We do have a blackbird nesting somewhere nearby and he sings regularly from our garden but it is sad that there don't seem to be many competitors nearby - we used to enjoy the singing duels in the evenings.  Sparrows too are fewer in number and therefore less noisy than they used to be in the tree outside our bedroom window, which at 5.00am is no bad thing to us although it is all part of a worrying trend.

We had assumed that all the recent building activity in and around Stari Grad was probably responsible for disturbing habitats and wildlife in general.  However, more worrying is the probability that the use of glyphosate-based herbicides has played a large role in their destruction.

  • Prime ministers of Australia and Iceland discuss effects on their countries even as some shy away in face of war and inflation

    World political leaders are descending on New York for the UN general assembly and some of them are putting the climate crisis on the agenda as they spoke on Monday at the start of the city’s annual Climate Week.

    This year’s Climate Week – which runs alongside UNGA – comes after months of extreme heat in large parts of the world including Europe and the US, wildfires in Africa, flash flooding in Asia and a record-breaking El Niño.

  • Scientists found unequal impact of the climate crisis would not be reversed even if implicit goal of the 2015 Paris agreement is achieved

    The unequal impact of the climate crisis on the world’s poorest people, including those in tropical areas, has been highlighted by new research that finds they will be among the last to feel the benefits if global greenhouse gas emissions are cut to net zero.

    Temperatures have risen more significantly in tropical areas relative to their historic range than at higher latitudes, including in wealthier countries in Europe and North America.

  • EVs with 90,000 to 120,000 miles on the clock are more likely to pass MOTs than petrol models of the same age

    Motorists buying a secondhand car with a lot of miles on the clock are likely to find an electric vehicle (EV) ultimately more reliable than a petrol vehicle, according to a study.

    An analysis of 47.4m MOT tests found that after cars were driven 90,000 to 120,000 miles, EVs were about 25% less likely to fail than petrol models of the same age (based on a failure rate of 16.5% versus 22.1%).

  • Forestry England invites people to help it create a record of when and how the season arrives across the country

    The reds and golds of autumn leaves may be beginning to appear, but exactly when the season arrives is not always as predictable as the calendar might suggest.

    Now, Forestry England is asking people to help track the changing colours of forests to create a record of when and how autumn arrives across the country.

  • The Argiope bruennichi, spotted in Cheshire for first time, part of worrying trend that could threaten native species

    She is an unlikely harbinger of the climate emergency: a venomous black and yellow spider who spins mysterious patterns in her webs and eats her mates for breakfast.

    Native to mainland Europe, north Africa and Asia, the Argiope bruennichi – commonly known as a wasp spider – is rarely seen in the north and west of Britain. But a fully grown female has been spotted in Cheshire for the first time by conservationists from Chester zoo, who stumbled across the large, brightly striped arachnid in a rewilded field.

  • New study finds subsidence caused by groundwater extraction can take place as far as 20km from site of mine

    The impact of opencast mining goes far beyond the edge of the pit. Studies of an opencast coalmine in western Germany show that opencast mining triggered extensive subsidence in the surrounding area and re-activated dormant geological faults.

    Underground mines are often associated with ground subsidence, but less is known about the risks associated with opencast mines. Researchers from the GFZ Helmholtz Centre for Geosciences in Potsdam, Germany, studied satellite data and geological field measurements from the area around the opencast Rhenish coalfields, between Aachen and Cologne.

  • New rice varieties give hope that farmers can overcome the climate emergency and a warmer future that threatens harvests

    When schoolchildren in Shiroishi were enlisted to plant rice seedlings in June, Shinto priests blessed the land and asked the deities for a bountiful crop. Judging by the fields behind farmer Haruki Kawasaki, their prayers have been answered.

    The 63-year-old is preparing to harvest this year’s crop of hinatamaru, a variety of rice whose plump grains have thrived despite exposure to another hot and dry summer, conditions that typically punish rice yields.

  • The risk to El Chaltén in Argentina has been known for years but recent findings and the Nepal disaster have brought planning for the worst-case scenario into sharp focus

    The images from Nepal stopped Daniela Schmidt in her tracks. A geologist at the University of Buenos Aires in Argentina, she watched the deadly flash floods on 26 August tear through everything in their path, people running for their lives as the water and debris swept over the landscape.

    “I had never seen anything like it,” she says. “This was one of the most catastrophic events on a global scale related to these glacial floods.”
