Birdwatch, June - July 2017

The summer months were intensely hot. By June 12th there was very little about. On a trip to the pond that morning I found that the biggest area was about to evaporate later that day– there was a tiny little pool with the remaining fish all gasping. Equally I saw a Cormorant, probably stocking up with an easy source of food.

There had been an influx of Alpine Swifts during those days, also a Cuckoo still calling near the pond 300-400 metres away.

As I’m sure most of you know the longest day marks the sign of change in nature’s calendar and the singing for territory and mate virtually ceases. Nightingale were one of the first to disappear: from my observations this year I would suggest there were reasonable numbers of Nightingales singing in “my patch”. Sadly despite numerous attempts, I have still yet to photograph one.

On July 15th, two keen bird-watchers, Will* and Eugenie, joined myself and Vivian for an early-morning tour of some bird-watching sites in our part of Hvar Island. They particularly wanted to see the Bee-eaters, so I had sent them a photograph I had taken on July 8th and warned them that good pictures might be hard to take on a single trip: "[Bee-eaters] don’t like you getting too close and also at the moment the sun is so bright difficult to get a really decent shot at this location. I’m also of the opinion they disperse to different locations in the day. Are you familiar with the call of Bee-eater? I can sometimes hear them over my garden in the afternoons but often quite high up when I come to look. So you might be lucky enough to hear them where you are staying....If you can get to Jelsa, although nothing is guaranteed, I should think we can knock off Bee-Eaters and Red Backed Shrike for you. Hoopoe are a little more difficult as are Woodchat Shrikes now, I’ve only seen two Hoopoe in the last month and both in flight whilst driving, and they have stopped calling now like most." (email July 9th 2017).

I also sent through a picture of a Turtle Dove, taken on July 8th, as they are a fairly rare sight in the UK now. The response was pleasingly enthusiastic: "Love those bird shots you took Steve. It's true, Turtle Doves are so rare these days in the UK it'll be lovely to see them." The words of true bird-lovers!

We started our quest in Pitve, moving on to the pond in the Stari Grad Plain, and then to Jelsa.

We were rewarded with more sightings than I expected, including an unknown wader at the pond. In Jelsa the Bee-eaters were happily swooping over their favourite nesting area.

It was a great start to Will and Eugenie's brief weekend visit, which was followed up by them spotting the elusive Golden Oriole near their accommodation.

Without doubt the highlight of my summer was being able to catch the Scops Owl in daylight, I just happened to pick up a contact call. Before, I had managed several shots at dusk, when it was coming to the power cables outside my house every evening, but the pictures were poor. On July 13th, I had a Scops on wire outside my house during the day, sadly it was off as soon as it saw me, I would have loved a daytime picture.

Then, on July 18th: done it! Albeit early in the morning (5:15am) as opposed to dusk where it would perch on my electric cable every night.

And then over the next couple of days came the real daytime shots. So I was delighted with these. Then I had some doubts as to whether it really was a Scops Owl, as reading about their behaviour Scops is apparently a true night owl, whereas the Little Owl (Sivi ćuk) can also be seen in the day, which I know from seeing them in the UK. Their calls are similar. However, a knowledgeable friend from the UK confirmed that in his opinion it was a Scops – they do have two forms, grey and brown.

Despite frequent visits to the pond and the airfield throughout the summer it remained very quiet and nothing new was observed. Perhaps you too noticed that numbers of Swallows were slowly building up on cables towards the latter part of July: on July 20th I counted 56 Swallow lined up on a power cable on my way back from Stari Grad ……was it a daytime roost or were they getting ready to go perhaps…?? and I believe the first weekend of August saw a lot move on. This doesn’t mean you won’t see a Swallow after that, but they are seen in smaller groups, as are Swifts and House Martins. Similarly Bee-eaters mainly went in August but I was still hearing them passing overhead as late as 13th September.

Photographed in and around Dol during the latter part of July, a just fledged Red Backed Shrike still being fed by parents. I was still seeing these birds around, mainly in single numbers, into mid September.

  • About 23 million people across country affected by water-saving measures with ‘prolonged dry weather’ in eight areas

    About 23 million people will be banned from using hosepipes by this weekend, as England and Wales moves closer to drought status.

    On Tuesday Thames Water became the latest water company to announce a hosepipe ban, covering the more than 10 million customers it supplies water to across London and the Thames valley.

  • Scientists recorded slower reduction over past 20 years, but study finds this was ‘temporary rather than sustained’

    A previously recorded slowdown in Arctic sea ice decline has ended, according to a new study, with the largest year-to-year wintertime reduction ever recorded.

    In a study published last summer, researchers found that melting sea ice in the Arctic had slowed down over the past 20 years, with no statistically significant decline in its extent recorded between 2005 and 2024.

  • Industry says government’s failure to address cooling demands means AI growth plans are ‘fatally flawed’

    The UK will not have enough water for future datacentres, the water industry has said in stark criticism of the government’s AI growth plans.

    Datacentres rely on large amounts of water to manage the heat generated by densely packed servers. Cooling towers, chillers and humidification systems make direct use of this water, with large volumes also consumed indirectly through high electrical power needs.

  • Hartington Meadows, Derbyshire: Amid a complex reticulation of stalks, stems, blooms and leaves, the right response might be to drop down before it

    In his glorious poem Haymaking, about a flower meadow, Edward Thomas describes how the fiery day “had a kernel sweet of cold” and “the white empty road was lightly strewn/With leaves”. The heat here, however, was unrelieved, and if the road was empty, it was also liquefying at its margin. Sweat banded my cap and ran in the creases at the backs of my bare legs, where, I noticed, the horseflies focused their attentions.

    Flower meadows, more than any other British land form, seem to be the most entangled and entangling places we have. They encircle and almost invade you with a sense of richness: not just the entwining hum of insect wings, nor the penetrating chromatic songs of the flowers themselves, but in an exuberant aura of living abundance.

  • Drivers in West Midlands say buses ‘unbearable’ during heatwaves, raising employee and passenger safety fears

    Bus drivers in the West Midlands have spoken out about the “horrendous” working conditions they have experienced during heatwaves, which led to 40C temperatures in their cabs.

    The UK was hit by high temperatures and dry weather in three successive heatwaves, with temperatures topping 37C last month when the country recorded its hottest ever June day. Last week, the Met Office warned climate extremes were becoming the “new ‘normal’ for the UK”.

  • The Guardian goes on the ground with Brazilian forces fighting to eradicate mining that has destroyed protected areas of Indigenous land

    The jerry-built bordello at the foot of Vila Cururu, an illegal gold-mining settlement at the heart of Brazil’s most desecrated Indigenous territory, was a hive of depravity until just a few weeks ago.

    Inebriated prospectors huddled around wooden tables, swigging beer and Scotch whisky, and ogling pole-dancing sex workers before going with them to shacks behind the brothel.

  • Experts warn increase in enhanced photos on birding platforms creating fake sightings, threatening credibility of tool used by scientists

    For many birdwatchers, recording a species outside its normal range is the holy grail. In the UK, the discoveries often make national headlines. The western reef heron, for example, usually found in Africa and southern Europe, was spotted in a seaside town in north Wales in June, and widely celebrated on birding forums.

    But a new scourge is threatening to disrupt the fun: AI slop.

  • Portable fans, a ‘cooling necklace’, sun protective hats and more products we reach for when the heat won’t quit

    If you’ve stepped outside lately, you know the heat isn’t letting up. With another round of triple-digit temperatures and heat advisories blanketing parts of the US, we asked our writers to share the things they rely on when summer gets unbearable.

    They shared recommendations for portable fans, a powerful dehumidifier and shorts that keep you cool even after hours of walking. Multiple writers recommended REI’s Sahara hoodie. You’ll also find clever picks you may not have considered, such as reusable ice packs and a “cooling necklace”. Here are our 12 tried-and-true essentials that are keeping us from melting on hot, sticky summer days.

  • Experts share tips to avoid the blood-sucking pests that can transmit Lyme disease and other illnesses on to humans

    I won’t go into gory detail about the tick I found latched behind my ear approximately 35 hours after a hike in early June. Suffice it to say, the parasite was well fed, and I was horrified.

    I am far from alone in making such a disgusting discovery. According to the Centers for Disease Control and Prevention (CDC), emergency room visits for tick bites have been unusually high in the US this year. Thirty-one million Americans are bitten by ticks annually – and the number has been trending up for over a decade. In the UK, ticks appear to be rising in number and species variety.

  • Air polluters try to ensure toxic emissions happen far from monitors – but the people who live nearby still feel it

    Kimbrelle Kyereh lives just a few hundred feet from the massive chemical storage tanks in St Rose, in south-eastern Louisiana. Oily fumes sometimes drift into her home, bringing headaches, nausea and insomnia. On one such night, she grabbed her son at 3am and fled to an all-night Ihop.

    In 2023, after years of coping with the noxious odors, Kyereh began collecting air samples in her yard for a local environmental justice group. But soon after, Louisiana passed an industry-backed law that sharply restricted how that kind of data could be used.

    Ten of Louisiana’s heaviest air-polluting facilities, based on self-reported data shared with the EPA, operate without a single public air monitor within five miles.

    This list includes Dow Chemical’s plastics factory in Plaquemine, which is about eight miles from the nearest air monitoring station. The station measures only ozone even though the plant releases an array of toxic pollutants including ethylene oxide, a known carcinogen.

    No public monitors measure ammonia – despite the fact that CF Industries’ Donaldsonville plant emits more than 7m lb of the hazardous chemical each year, according to EPA data.

    The three chemicals that researchers have concluded “together account for the large majority of total cancer risk” in the area – ethylene oxide, chloroprene and formaldehyde – aren’t monitored by the state at all.

  • Crijevo potpuno obnavlja svoju unutarnju sluznicu svakih nekoliko dana što je jedan od najbržih procesa obnove u ljudskom tijelu. Znanstvenici su sada otkrili da ovaj izvanredan podvig prati skrivena mreža specijaliziranih mezenhimalnih potpornih stanica koje rade iza kulisa, otkrivajući neočekivanu razinu organizacije unutar crijeva i nudeći nove tragove koji bi na kraju mogli informirati pristupe ozljedama crijeva i upalnim bolestima crijeva.

  • Antimikrobna rezistencija kod djece raste globalno i pogoršat će se tijekom sljedećeg desetljeća, ugrožavajući učinkovitost antibiotika koji spašavaju živote, prema prvoj svjetskoj platformi za praćenje.

  • Niska konzumacija voća i povrća glavni je preventabilni faktor kardiovaskularnih bolesti (KVB). Procjenjuje se da nedovoljan unos voća i povrća uzrokuje gotovo 3 milijuna smrtnih slučajeva od kardiovaskularnih bolesti i više od 70 milijuna godina života prilagođenih invaliditetu diljem svijeta.

  • Prethodne studije su otkrile da je kofein najpopularniji stimulans i psihoaktivna tvar na svijetu, a kava je najčešći način na koji ljudi konzumiraju kofein. Najnovija istraživanja podupiru zaključak da je za većinu odraslih osoba konzumiranje do 400 mg kofeina dnevno (ili do 5 šalica kave s kofeinom od 240 ml dnevno) sigurno i čini se da je povezano s nižim rizikom od kardiovaskularnih bolesti za neke osobe. Međutim, veće doze kofeina, poput razina koje se nalaze u energetskim pićima, mogu uzrokovati kardiovaskularnu štetu.

  • Šestomjesečno kliničko ispitivanje pokazalo je da su osobe s visokim genetskim rizikom za pretilost imale jednake koristi od savjetovanja o prehrani kao i one s niskim genetskim rizikom, što dovodi u pitanje ideju da DNK određuje uspjeh mršavljenja.

  • Epilepsija pogađa otprilike 50 milijuna ljudi diljem svijeta, no više od polovice osoba s pretpostavljenim genetskim uzrokom još uvijek nema molekularnu dijagnozu unatoč identifikaciji preko 1.000 monogenskih gena epilepsije. Malo je vjerojatno da će se ova dijagnostička praznina riješiti samo poboljšanim otkrivanjem varijanti, što sugerira da se varijante koje utječu na isti biološki put mogu kombinirati i uzrokovati bolest. U nedavno provedenom istraživanju znanstvenici su otkrili novi genetski put koji može dovesti do napadaja kada je isti poremećen.

Sada je novo istraživanje otkrilo veću toksičnost bez koristi za preživljavanje od nastavka liječenja do progresije bolesti u usporedbi s prekidom nakon 2 godine.

  • Znanstvenici Icahn School of Medicine at Mount Sinai identificirali su imunu stanicu koja djeluje kao arhitekt i koordinator snažnih imunoloških središta koja se formiraju unutar tumora i igra ključnu ulogu u antitumorskom imunitetu. Ovo otkriće moglo bi dovesti do novih strategija za učinkovitije imunoterapije raka.

  • Plućna fibroza je smrtonosna bolest u kojoj ožiljno tkivo raste u plućima, otežavajući disanje. Naime, kod plućne fibroze, normalan proces zacjeljivanja rana u tijelu ide po zlu. Umjesto da se popravlja oštećeno tkivo, ono počinje proizvoditi ožiljno tkivo u plućima. Osobe s idiopatskom plućnom fibrozom imaju vrlo kratko vrijeme preživljavanja, obično samo dvije do pet godina od dijagnoze. Samo su dva lijeka odobrena za liječenje, a nijedan od njih ne može preokrenuti ožiljke i izliječiti bolest.

  • Znanstvenici su identificirali praktični prag ketona u krvi povezan s većim kratkoročnim gubitkom težine, nudeći novi uvid u to kako praćenje ketoze može pomoći u optimizaciji ketogenih dijetalnih intervencija. Identificirana razina ketona u krvi mogla bi pomoći u predviđanju koje osobe će najvjerojatnije postići veći gubitak težine tijekom ketogene dijete.
