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.

  • National Trust says these are ‘alarm signals we cannot ignore’ as climate breakdown puts pressure on wildlife

    Extremes of weather have pushed nature to its limits in 2025, putting wildlife, plants and landscapes under severe pressure, an annual audit of flora and fauna has concluded.

    Bookended by storms Éowyn and Bram, the UK experienced a sun-soaked spring and summer, resulting in fierce heath and moorland fires, followed by autumn floods.

  • Planet’s oldest bee species and primary pollinators were under threat from deforestation and competition from ‘killer bees’

    Stingless bees from the Amazon have become the first insects to be granted legal rights anywhere in the world, in a breakthrough supporters hope will be a catalyst for similar moves to protect bees elsewhere.

    It means that across a broad swathe of the Peruvian Amazon, the rainforest’s long-overlooked native bees – which, unlike their cousins the European honeybees, have no sting – now have the right to exist and to flourish.

  • Attenborough, 99, enthuses about tube-riding pigeons, foxes, parakeets and others in Wild London for the BBC

    Filming the wildlife of London requires an intrepid, agile presenter, willing to lie on damp grass after dark to encounter hedgehogs, scale heights to hold a peregrine falcon chick, and stake out a Tottenham allotment to get within touching distance of wary wild foxes.

    Step forward Sir David Attenborough, who spent his 100th summer seeking out the hidden nature of his home city for an unusually personal and intimate BBC documentary.

  • In 2014 the Malaysian Airlines jet vanished over the Indian Ocean. Now the team that located Shackleton’s Endurance is looking again with the latest undersea robots

    More than a decade after Malaysia Airlines flight MH370 went missing after veering thousands of miles off course, its location remains unknown.

    The Malaysian government has promised to pay a private company, Ocean Infinity, $70m (£56m) to search for the plane on a “no find, no fee” basis.

  • Old Sulehay Forest, Northamptonshire: Distant church bells are about all I can hear as I stand below a 500-year-old small-leaved lime – a tree that may be making an unlikely comeback

    On a bright winter’s day, I stand at the centre of a ring of multi‑stemmed small-leaved limes. Their gnarled bases are furred with moss and feathered with sprays of epicormic growth. Lime trees are notoriously hard to age, but this one is probably more than 500 years old, shaped and reshaped by centuries of coppicing, now with a vast canopy stretching nearly 20 metres.

    Looking up, I marvel at the intricate fractal lattice of branches and twigs of each tree. Every stem holds its own space, the crowns kept neatly apart from their neighbours – a quiet phenomenon known as crown shyness. This seems somehow appropriate, given how quiet the woodland is. It feels emptied, with only the rush of a chill wind numbing my bare fingertips, a peal of distant church bells, and a robin offering its muted winter song.

  • Spring-like weather experienced by many Americans to end, while heavy snow in Japan brings deadly conditions

    A week of extremes in the US as Arctic air plunges southwards across many states, sweeping away record-breaking warmth from last weekend. With low pressure in the west drawing up warm, humid air from the Gulf of Mexico, much of the south and midwest basked in spring-like weather this weekend with temperatures widely an extraordinary 15-20C above normal for late December.

    This week, however, most people will ditch their summer clothes for hats and scarves as a ridge pressure builds across the west, allowing for a polar air mass to dive southward, bringing freezing temperatures and the risk of snow.

  • With the snow line edging higher, 186 French ski resorts have shut, while global heating threatens dozens more

    When Céüze 2000 ski resort closed at the end of the season in 2018, the workers assumed they would be back the following winter. Maps of the pistes were left stacked beside a stapler; the staff rota pinned to the wall.

    Six years on, a yellowing newspaper dated 8 March 2018 sits folded on its side, as if someone has just flicked through it during a quiet spell. A half-drunk bottle of water remains on the table.

  • When the hot winds hit Roebourne, as many as 16 people pile into Yindjibarndi elder Lyn Cheedy’s home – one of the few with air conditioning

    Few places are more exposed to extreme weather than Roebourne, a tiny cyclone-prone town on the Western Australian coast, where public housing residents endure 50C heat without air conditioning.

    Lyn Cheedy, a Yindjibarndi elder, takes her grandson to the pool most afternoons.

  • Trump ratcheted up his questionable claims about the environment and how to deal, if at all, with the threats to it

    In the past decade at the forefront of US politics, Donald Trump has unleashed a barrage of unusual, misleading or dubious assertions about the climate crisis, which he most famously called a “hoax”.

    This year has seen Trump ratchet up his often questionable claims about the environment and how to deal, if at all, with the threats to it. In a year littered with lies and wild declarations, these are the five that stood out as the most startling.

  • Action began in January, before an all-out strike in March. For locals, the flytipping, vermin, maggots and mess are taking a huge environmental and emotional toll

    It’s an icy cold winter morning, and 80-year-old Mohammed Bashir is armed with a broom, tackling the large pile of rubbish that has accumulated outside his terraced house in Small Heath, Birmingham.

    This has become an almost daily activity for Bashir since the city’s bin strike started 50 weeks ago and, like many in the city, he is starting to lose patience.

  • Briga oko spajanja kraja s krajem stari vaše srce jednako kao i klasični čimbenici rizika za srčane bolesti, tvrdi nova studija. Naime, pokazalo se, da su financijski pritisak i nesigurnost u vezi s hranom najjači pokretači ubrzanog starenja srca.

  • Nakon traumatske ozljede mozga, neki se pacijenti mogu potpuno oporaviti, dok drugi zadržavaju teške invaliditete. Točna procjena prognoze je izazovna kod pacijenata na terapiji održavanja života. Iako funkcionalna magnetska rezonancija u mirovanju (rs-fMRI) može procijeniti neurološku aktivnost ubrzo nakon ozljede mozga, nije poznato predviđa li komunikacija između regija mozga u ovom ranom trenutku dugoročni oporavak.

  • Diljem svijeta uobičajene infekcije postaju sve teže za liječiti. Novi pregled prikazuje otrežnjujuću sliku globalne antimikrobne rezistencije (AMR), prateći kako se bakterije i gljivice razvijaju brže nego što medicina može reagirati. Uspoređujući podatke o rezistenciji iz više sustava nadzora, znanstvenici su identificirali alarmantne trendove: rastuću otpornost na antibiotike posljednje linije, regionalne nejednakosti i brzo širenje rezistentnih gena putem globalnih putovanja i poljoprivrede.

  • Nova analiza više studija otkriva da proizvodi od kanabisa koji sadrže relativno visoke razine psihoaktivnog spoja tetrahidrokanabinola, obično poznatog kao THC, mogu pružiti kratkoročna poboljšanja boli i funkcije. Međutim, pregled je otkrio da proizvodi na bazi THC-a dovode do povećanog rizika od uobičajenih štetnih simptoma poput vrtoglavice, sedacije i mučnine.

  • Izgleda da tajna zdravijeg i mlađeg srca leži u vagusnom živcu. Naime, nova studija je pokazala da je očuvanje bilateralne srčane vagusne inervacije faktor protiv starenja srca. Posebno se desni srčani vagusni živac pojavljuje kao pravi čuvar zdravlja kardiomiocita, pomažući u očuvanju dugovječnosti srca neovisno o otkucajima srca.

  • Istraživanje koje je trajalo 10 godina otkrilo je da starije žene koje piju čaj imaju nešto jače kosti od svojih vršnjakinja koje konzumiraju kavu. Valja istaknuti, da čak i mala poboljšanja gustoće kostiju mogu smanjiti rizik od prijeloma kostiju.

  • Prema rezultatima nove studije, više od 1 od 10 odraslih osoba starijih od 70 godina ispunjavalo je kriterije za terapiju monoklonskim antitijelima koja bi potencijalno mogla usporiti kognitivni pad.

  • Američki znanstvenici s The University of Texas MD Anderson Cancer Centre otkrili su da mitohondrijski enzim, GFER, stvara imunosupresivno okruženje unutar tumora gušterače, što dovodi do otpornosti na liječenje, a inhibicija GFER-a u kombinaciji s blokadom imunoloških kontrolnih točaka rezultira snažnim antitumorskim odgovorom u predkliničkim modelima, ističući potencijalnu terapijsku strategiju za pacijente s rakom gušterače.

  • Limfedem nakon raka glave i vrata znatno je češći nego što se prije pretpostavljalo i može trajati dugo nakon završetka liječenja raka. No, sada su švedski znanstvenici s Lund University otkrili da pacijenti s niskom razinom tjelesne aktivnosti imaju veći rizik od razvoja limfedema.

  • Pacijenti doživljavaju značajne promjene u crijevnim bakterijama na početku upalne bolesti crijeva (IBD), otkrila je nova studija, nudeći novu nadu za raniju dijagnozu i buduće liječenje.
