Nature Watch, May 2018

Steve Jones, ever on the watch for birds, has some exciting sightings in May.

As Steve reports: Not a great deal to report in May, primarily as two weeks were spent in the UK. That said, the last two weeks of the month have been very interesting with several new sightings which I had not seen before on the island or elsewhere. Also without doubt I had an element of luck, being at the right place and the right time, as two of the new species were just glimpses: I saw the Sand Martin just once among swifts and swallows, and spotted the Lesser Grey Shrike just for a few seconds, but I was still just able to get photographic record shots for confirmation, though not good enough for publication. The Nightjar I recognized by its call, but as I have no hope of getting a daytime picture of one, I am aiming to be more successful with a night-time photo.

If you are an early riser around 04:30-04:45 you may have heard the “dawn chorus”. It's well worth getting up for at this time of year, even if you only do it once! More generally, you have probably noticed this month several species of bird carrying food to their young.

If you are not familiar with House Martins, there is a good opportunity to see them in action at the post office in Vrbanj. They have built a nest right above the door, where the adults fearlesslyfeed their young, so no need for any binoculars or fancy equipment. Closer to home, in my garden, I have a Red Backed Shrike sitting on eggs (presumably). I took the photograph above last week of another Red Backed Shrike, also sitting, about 100 metres from my house.

The male (pictured above) was to be seen quite close by where the female was sitting. There were four young in the nest, which fitted in perfectly until about mid-June. By 17th June, they were so big they were struggling to fit into the nest. Much as I wanted to get a picture of the adults feeding the young, I realised it was pretty well impossible, as they obviously kept away if they saw me anywhere near the nest.

The Black Headed Bunting arrived at pretty much the same time as last year but I have only seen one so far, so they are nothing like as common as the Red Backed or Woodchat Shrikes.

I had a friend visiting for a few days and whilst out one morning we came across three Rose Coloured Starlings for a matter of seconds. I managed to get a record shot but before I could get another picture they were off.

Just minutes after this another first for the island – and that at the pond I visit almost daily. The Squacco Heron, this stayed for three days before moving on.

Without doubt the highlight of the month was a short visit of two Rollers (zlatovrana). The photographs are poor as they were some distance and as it was a first for me. I spent more time looking through the binoculars at the birds than photographing. That said some adequate record shots. These were visible for about three minutes and despite me scouring the area pretty well every day since, no signs.

During the next three months I won’t be going out as frequently. Already things are beginning to quieten down, the Nightingale, which was singing incessantly, has already cut its singing down. I have only heard one Cuckoo in the last five days, but interestingly this year I have heard a female Cuckoo a few times. I still wonder what the host bird may be. My thinking is it might be a Corn Bunting, so if you see an active Corn Bunting, check it out: you never know, it may be feeding a Cuckoo!

The pond I visit is holding its water levels well, there are signs now of it dropping but it is still considerably higher than this time last year. I am also noticing quite a lot of dragonfly activity, several Emperors, Broad Bodied Chasers and an Emerald damselfly (I am awaiting confirmation on which Emerald species).

Finally a shot of everyone’s favourite ……………………….the Bee-Eater, which is one of the strongest draws attracting birding enthusiasts from cooler climates to Hvar.

  • Sudden shifts from wet to dry weather, or vice versa, may foil typical drought- and flood-prevention measures

    Rising temperatures may trigger a dangerous increase in “hydroclimatic whiplash” in rivers that would make traditional approaches to flood and drought planning insufficient, a study has found.

    As temperatures rise owing to the worsening climate crisis, rivers will experience increasingly rapid transitions between heavy downpours and long dry spells – called hydroclimatic whiplash events – because a warmer atmosphere holds more moisture, intensifying rainfall extremes.

  • London Tree Ring project aims to create corridors of plant and animal life around the city to strengthen its biodiversity

    Harry Ewing is heaping branches and foliage from the forest floor on to a dead hedge, reinforcing the protective circle around his newly planted trees in Hadley Wood, north London. He is in a glade created by a fallen oak that was previously overrun with thick bramble.

    “I feel very happy – the trees are growing already. It’s really nice seeing it when it starts,” says Ewing.

  • Scientists are returning to a wartime solution that may be more sustainable than the traditional rubber tree

    There is a global shortage of natural rubber and dandelions may be coming to the rescue. In the second world war there was such a severe shortage of rubber that the Allies used the Russian dandelion, Taraxacum koksaghyz, from Kazakhstan. Soviet scientists found the dandelion roots produced enough white milky latex to make natural rubber, but when the war ended producers returned to the traditional rubber tree, Hevea brasiliensis.

    But the demand for rubber is now increasing, with rubber trees suffering from a fungal disease and the impacts of extreme weather caused by the climate crisis. So, scientists are looking again at using dandelions, with the added benefit that they grow in temperate climates, are a sustainable crop that do not need pesticides and lots of water, and don’t lead to the deforestation common in tropical rubber tree plantations.

  • Frome, Somerset: This much-maligned midsummer menace has few friends among humans, but look closely and you might find an orgy of eating and mating

    Eyes smarting, throat tickling, nostrils dog-wet, I pick my way along a thready footpath up the combe, only half-prepared for the next irritation. Nettles, I am watching you. But not well enough it seems, for a sneaky one hidden under the skirts of encroaching grasses and umbellifers grazes the back of my bare calf. It induces that tingling somewhere between pain and pleasure – one that quickly develops into a needling throb.

    It is hard to love a nettle. This much-loathed plant may be one of the first that many children learn to identify, for their own protection. It has a secondhand look, with wrinkly, crinkly jagged hearts for leaves. It has no sheen; it does not shine. Near-invisible fine hairs on the upper surfaces give the dulled green a dusty, soiled appearance.

  • Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance

    The ocean is running a fever. In 2025, the number of days of marine heatwaves – prolonged spells when the sea turns abnormally, dangerously warm – was more than triple what it was in the early 1990s.

    These are not abstract statistics. A severe and persistent marine heatwave bleaches coral reefs, strips away the kelp forests that shelter young fish, empties fishing grounds and – if occurring frequently – can tip whole ecosystems past the point of recovery.

  • Two-thirds of Americans say they are worried about climate but level of media coverage does not reflect this

    US political and media discourse has drifted away from the climate crisis amid a frontal assault by Donald Trump upon policies to limit global heating and the president’s pugnacious demands to “drill, baby, drill” for more oil and gas.

    Yet while elite attention on climate has waned, even among some previously vocal Democrats who have wound back on criticism of the fossil fuels that are overheating our planet, the American public remains concerned about the climate crisis and continues to favour action to deal with it, according to experts and polling.

  • Sea ice is melting fast, worsening the climate crisis, but a bold attempt to rethicken it is showing early signs of success

    ‘This would have been a wild dream a year ago,” says Andrea Ceccolini, standing on Arctic sea ice just a 4-mile snowmobile ride from the Inuit town of Cambridge Bay, northern Canada. To his left are sky blue ponds of meltwater created in the last few days by a sun that no longer sets in the high north summer. To his right, the sea ice is still a brilliant white, the light dusting of snow on top continuing to sparkle.

    “It’s incredibly different, the boundary – I mean, you can point to it,” he says. The difference is the result of a bold geoengineering experiment being conducted by Ceccolini’s company, Real Ice, funded by the UK government.

  • Many small-scale landowners now include conservation measures alongside everyday farming. But progress is precarious, and the threat of guerrilla violence and poverty remain whichever candidate wins

    Like most people settling in the area, Pablo Peña was seeking to escape violence and make a living from a patch of land when he moved to Guaviare in central Colombia. While his life has been strongly marked by conflict and deforestation, more than 30 years on he now focuses on community work and conservation.

    Peña first visited Guaviare during his mandatory military service. Years later, in 1994, he settled down to farm in Guaviare’s Calamar, a town in a remote corner of the Amazon.

  • Residents of West Oakland, which suffers from toxic waste and high pollution rates, rally against a coal export facility

    West Oakland, a California neighborhood known for its rich history of Black activism from the Pullman Porters’ union to the Black Panthers, might not seem like the site of the country’s next great coal project.

    But that’s exactly what the Trump administration is pushing for – with the injection of $75m to build a sprawling coal export terminal in the nearby port of Oakland.

  • ‘Saddened, stunned, surprised and haunted’ is how one surfer describes the mood at the popular Sydney beach two days after Leah Stewart was bitten by a great white

    Under a clear blue sky on a Monday morning, Coogee beach in Sydney’s east is quiet.

    A few swimmers have ventured into the ocean pools at the northern and southern ends of the beach. Most others sit on the sand, looking towards the water.
