Brief Nature Watch, Spring 2022

Nature watcher Steve Jones paid a short visit to Hvar in April.

Steve has now moved back to the UK for family reasons, but is still drawn to Hvar and its beautiful natural resources. He plans to visit as often as he can. This is his report from the few days he was on the island in April.

"Nice to be back! A very brief visit to “my old patch” on the island brought in the usual expected sightings. It gave me great pleasure to walk along the airfield and down to the pond, catching what is about, no day ever the same.

Some birds were singing and setting up territory, so you know if a Cirl Bunting is singing at the bottom of the airfield it will be singing daily from that area, and a further two of them were heard on the way to the pond. Early April is a great time to visit as birds are arriving and setting up territories, while others are passing through to breed elsewhere – 4th April for example I saw a Redstart, only seen twice before on the Island (unlike the Black Redstarts that come in in October for the Winter), this will be clearly moving on.

Before I reached the island I saw several Swallows flying over between Zagreb and Split, and there were good numbers on Hvar over the airfield and around the pond. Some clearly just arriving.

During the first couple of days the weather turned colder, but there were still quite a few birds to see, including the Wheatear.

On Sunday 3rd April 60-70 Yellow Legged Gulls were on the airfield where there was a covering of a heavy of hail appearing like snow. [Weather expert Norman Woolons identified this type of soft hail as 'Graupel'.]

At the lower end of the airfield I picked up by call some yellow wagtails, I am thinking about 20 . You get several sub species of yellow wagtail so I group them all in the main species.

Of those I saw, one had a blue head, the other a black head. I saw another species at the pond but could not get a clear enough picture to publish.

Whilst walking down to the pond saw a Kestrel perched on a tree looking out for prey and also a solitary Corn Bunting.

Sardinian warblers, which are resident, were also singing and calling.

On 4th April saw my first Whitethroat of the year, two others elsewhere on following days. Sadly I was not quick enough for a picture. Sub Alpine warblers, also recent arrivals, were beginning to sing, I saw them at three locations.

I had read and been told that Nightingales had already been in for a couple of weeks, so I was really disappointed in not hearing one, particularly when normally there would be three in 'my patch'. Nightingales are rarely seen, but I was lucky enough some time ago to have a regular Nightingale singing on display every morning in the early summer at about 06:30-06:45. Sadly all the pictures I took were looking into bright sunshine, so I have never managed to catch a decent picture of one. However a friendly, rather quizzical blackbird made up for that disappointment!

There was a Wood Sandpiper or two at the pond and around but they are very sensitive to sound / movement. A couple of times I saw them fly well before I was at the pond or nearby. However the one day I first of all manged to see one through the short grass and managed a picture. It didn’t fly so I persevered for 30-40 minutes. Another flew in as well. I managed eventually a couple of quite decent pictures and getting to within five or so metres of the bird, obviously delighted.

Last Wednesday I heard my first Cuckoo once again from an area heard in previous years. Sadly can’t get close enough to get a picture or even a sighting and it was only calling sporadically. Finally after visiting my old neighbours in Dol on Thursday, as I was leaving a Hoopoe flew right in front of the car, so I was delighted with that.

I saw a Mongoose on three separate occasions, possibly the same one three different times, once standing on its hind legs.

Also whilst out I saw several butterflies on the wing, Orange Tip, Bath White, Wall Brown and both Swallowtail and scare Swallowtail.

While I saw nothing that surprised me but more than happy with all the species picked up. Here's the list, in no special order:

Cirl Bunting
Swallow
Sardinian warbler
Chaffinch
Great tit
Cuckoo
Hoopoe
Blackcap
Hooded crow
Yellow legged gull
Wheatear
Kestrel
Blue tit
Wood sandpiper
Yellow wagtails
Serin
Corn bunting
Sub alpine warbler
Whitethroat
House Martin
Redstart
Greenfinch
Blackbird
Pheasant
Buzzard
Sparrowhawk

Until the next time ……………………."

Footnote: Steve is sorely missed on Hvar, but we know he will be back as often as he can. In the UK, his birdwatching is very fruitful, and he has many like-minded friends to share his interest with. Shortly after his return, he sent us this picture of a Yellowhammer, a bird he has never seen on Hvar.

  • Exclusive: Campaigners claim changes will let companies ‘off the hook’, as government prepares to unveil new white paper for water industry

    Water companies could be let off fines for polluting the environment under changes announced in the government’s new white paper.

    The environment secretary, Emma Reynolds, hailed the changes as “once-in-a-generation reforms” featuring “tough oversight, real accountability and no more excuses”.

  • The Andaman coast was one of very few places in the world with a viable population but then dead dugongs began washing up. Now half have gone

    A solitary figure stands on the shore of Thailand’s Tang Khen Bay. The tide is slowly rising over the expanse of sandy beach, but the man does not seem to notice. His eyes are not fixed on the sea, but on the small screen clutched between his hands.

    About 600 metres offshore, past the shadowy fringe of coral reef, his drone hovers over the murky sea, focused on a whirling grey shape: Miracle, the local dugong, is back.

  • Changing temperatures may be behind change in behaviour, which experts fear threatens three species’ survival

    Penguins in Antarctica have radically shifted their breeding season, apparently as a response to climate change, research has found.

    Dramatic shifts in behaviour were revealed by a decade-long study led by Penguin Watch at the University of Oxford and Oxford Brookes University, with some penguins’ breeding period moving forward by more than three weeks.

  • Studies detecting microplastics throughout human bodies have made for alarming reading in recent years. But last week, the Guardian’s environment editor, Damian Carrington, reported on major doubts among a group of scientists about how some of this research has been conducted.

    Damian tells Ian Sample how he first heard about the concerns, why the scientists think the discoveries are probably the result of contamination and false positives, and where it leaves the field. He also reflects on how we should now think about our exposure to microplastics

  • Even 25% increase in meat and dairy consumption would require 100m more acres of agricultural land, analysis says

    The Trump administration’s new dietary guidelines urging Americans to eat far more meat and dairy products will, if followed, come at a major cost to the planet via huge swathes of habitat razed for farmland and millions of tons of extra planet-heating emissions.

    A new inverted food pyramid recently released by Donald Trump’s health department emphasizes pictures of steak, poultry, ground beef and whole milk, alongside fruits and vegetables, as the most important foods to eat.

  • Intense rainfall has caused the water to go murky in some areas, making them attractive spots for fish and sharks to feed

    Four people have been attacked by sharks in New South Wales in 48 hours, including three incidents at Sydney beaches.

    Any shark bite incident is traumatic and Sydney swimmers have been warned to stay out of the water.

  • Buxton, Derbyshire: Others are taller, wider, older, but our varied stock of willows have a generosity that sets them apart

    Usually in this country when we think about important trees, we focus on height, girth, age, visual impact – in short, their material properties. Few therefore would probably name willow as a number one British species.

    Willows often have no central trunk as in our archetypal tree model, and few specimens are more than 7 metres tall. Yet there is a sphere in which willows are pre‑eminent: more invertebrates live on them (452 species) than any other trees, including oaks, their closest contenders (423). In his glorious guide Trees of Britain and Ireland, Jon Stokes points out that 160 lichens thrive on willows too.

  • As Labour shakes up regulation, suppliers are finally investing – but face problems such as contractor shortages and inflation

    When a sluice gate failed 24 metres below the water’s surface at Thames Water’s Queen Mother reservoir near London’s Heathrow airport, there were no easy fixes available. Emptying 37m cubic metres (1,307m cu ft) of water was not an option, meaning that helmeted divers were limited to 98-minute stints in the high-pressure environment.

    The risky project required a team on a floating platform with a crane to cut out the broken equipment with thermal lances, bolt a plate on to the reservoir wall, and install the new equipment. It took more than a year until last October to complete, according to Glenfield Invicta, the contractor that carried out the work for Thames Water.

  • Experts call for tighter regulation as GPS tracking reveals how people’s behaviour affects the lives of some of the world’s largest birds

    Many people look up to admire the silhouette of raptors, some of the planet’s largest birds, soaring through seemingly empty skies. But increasingly, research shows us that this fascination runs both ways. From high above, these birds are watching us too.

    Thanks to the development of tiny GPS tracking devices attached to their bodies, researchers are getting millions of data points on the day-to-day lives of these apex predators of the skies, giving us greater insight into where they hunt and rest, and how they die.

  • A return to nuclear power is at the heart of Japan’s energy policy but, in the wake of the 2011 disaster, residents’ fears about tsunamis, earthquakes and evacuation plans remain

    The activity around the Kashiwazaki-Kariwa nuclear power plant is reaching its peak: workers remove earth to expand the width of a main road, while lorries arrive at its heavily guarded entrance. A long perimeter fence is lined with countless coils of razor wire, and in a layby, a police patrol car monitors visitors to the beach – one of the few locations with a clear view of the reactors, framed by a snowy Mount Yoneyama.

    When all seven of its reactors are working, Kashiwazaki-Kariwa generates 8.2 gigawatts of electricity, enough to power millions of households. Occupying 4.2 sq km of land in Niigata prefecture on the Japan Sea coast, it is the biggest nuclear power plant in the world.
