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.

  • Deal expected to pave way for further scientific study, boost conservation and open up access to Dorset chalk figure

    The mystery of when, how and – perhaps most importantly – why a giant naked figure was carved into a dizzyingly steep hillside in the English West Country has been a source of wonder and intrigue for centuries.

    Future generations may come closer to solving the puzzle of the Cerne Giant after the National Trust stepped in to buy 340 acres of land around the 55-metre (180ft) figure.

  • Exclusive: Brazil’s environment minister talks about climate inaction and the course we have to plot to save ourselves and the planet

    Soon after I returned home to Altamira from Cop30, I found myself talking about dinosaurs, meteors and “ambassadors of harm” with Brazil’s environment minister, Marina Silva.

    No one in government knows the rainforest better than Marina, as she is best known in Brazil, who was born and raised in the Amazon. No one is more aware of the sacrifices that environmental and land defenders have made than this associate of the murdered activist Chico Mendes. And no one worked harder to raise ambition at Cop30, the first climate summit in the Amazon, than her. So what, I asked, had it achieved?

  • Fertilising arable land with human waste leaves array of toxins that could re-enter food chain, study finds

    More than 520 chemicals have been found in English soils, including pharmaceutical products and toxins that were banned decades ago, because of the practice of spreading human waste to fertilise arable land.

    Research by scientists at the University of Leeds, published as a preprint in the Journal of Hazardous Materials, found a worrying array of chemicals in English soils. Close to half (46.4%) of the pharmaceutical substances detected had not been reported in previous global monitoring campaigns.

  • Pew Charitable Trusts finds plastic pollution will more than double globally by 2040 unless action taken

    The 66m tonnes of pollution from plastic packaging that enters the global environment each year could be almost eliminated by 2040 primarily by reuse and return schemes, significant new research reveals.

    In the most wide-ranging analysis of the global plastic system, the Pew Charitable Trusts, in collaboration with academics including at Imperial College London and the University of Oxford, said plastic, a material once called revolutionary and modern, was now putting public health, world economies and the future of the planet at risk.

  • These delicate cloud systems appear to be seeded by massive atmospheric waves thousands of miles away

    Cirrus clouds are our highest clouds; their delicate wispy strands are like an artist’s brushstrokes through the sky. During the day they are bright white and at dawn and dusk they can take on the hues of sunrise and sunset. But how are they made? New research reveals that some cirrus clouds are seeded by storms on the other side of the world, many thousands of miles away. This has implications for global heating as storm patterns shift.

    Meteorologists have long recognised two types of cirrus cloud: “anvil” cirrus, which spread out from large storm systems, and “in-situ” cirrus, which seem to form on their own. Telling them apart is tricky, but by applying a new computer analysis to cloud satellite data, researchers spotted that in-situ cirrus emerged in response to major storm systems on the other side of the Earth.

  • Inkpen, Berkshire: Drifting in and out of sleep on the woodland floor, I’m in searing pain, but far from alone

    It was nobody’s fault, but here I am, lying on the damp floor of a wood, half a mile from the road. Drifting down with the falling leaves are the voices of two women, too easily accepting of blame. I reassure them and try to sit up, but the high singing in my ears turns to static, the edges of the wood begin to pixelate, and I lie down again before I faint.

    Moments earlier, deep into Long Copse, Mum’s one-year-old labrador and my two-year-old collie crossbreed had met a young whippet. A case of the zoomies ensued, and as I turned to warn Mum, there was a sledgehammer blow to my lower leg as one, two or maybe all three dogs cannoned into me. Though I didn’t realise for two more days, my leg was broken before I hit the ground.

  • From the threat of superintelligent AI to the secrets of a longer life; plus the evolution of language and the restless genius of Francis Crick

    This felt like the year that AI really arrived. It is on our phones and laptops; it is creeping into digital and corporate infrastructure; it is changing the way we learn, work and create; and the global economy rests on the stratospheric valuations of the corporate giants vying to control it.

    But the unchecked rush to go faster and further could extinguish humanity, according to the surprisingly readable and chillingly plausible If Anyone Builds It, Everyone Dies (Bodley Head), by computer scientists Eliezer Yudkowsky and Nate Soares, which argues against creating superintelligent AI able to cognitively outpace Homo sapiens in all departments. “Even an AI that cares about understanding the universe is likely to annihilate humans as a side-effect,” they write, “because humans are not the most efficient method for producing truths … out of all possible ways to arrange matter.” Not exactly cheery Christmas reading but, as the machines literally calculate our demise, you’ll finally grasp all that tech bro lingo about tokens, weights and maximising preferences.

  • Even tiny ponds can create biodiversity hotspots, as well as helping out during heatwaves and heavy rain

    A few years ago I created a little pond in my back garden. It’s barely bigger than a paving slab, but since the pond has been in place we have had a garden teeming with frogs, hedgehogs have taken up residence and bird life has abounded.

    Not only do humble ponds like this give nature a boost; they also help to buffer climate extremes. In recent decades, Britain’s ponds have been disappearing, with research revealing that more than half of our dense network of ponds has been lost since the 1900s. Lucy Clarke and colleagues found that 58% of ponds in the Severn Vale region of the UK had been lost since the 1900s, with the average distance between ponds increasing by 25 metres over that time. Similar trends can be seen worldwide, with intensive agriculture and urbanisation obliterating these seemingly insignificant bodies of water.

  • Nootka lupins, introduced in the 1940s to repair damaged soil, are rampaging across the island, threatening its native species

    It was only when huge areas of Iceland started turning purple that authorities realised they had made a mistake. By then, it was too late. The Nootka lupin, native to Alaska, had coated the sides of fjords, sent tendrils across mountain tops and covered lava fields, grasslands and protected areas.

    Since it arrived in the 1940s, it has become an accidental national symbol. Hordes of tourists and local people pose for photos in the ever-expanding fields in June and July, entranced by the delicate cones of flowers that cover the north Atlantic island.

  • It borders Brazil, but French Guiana is now a remote outpost of the EU. It is home to Europe’s only spaceport, some of the most biodiverse forest on the planet and a military mission that is testing the limits of western power

    Above me, a ceiling of rough wooden branches and tarp. To my right, an officer in the French Foreign Legion types up the daily situation report. In front of me a French gendarme named David is standing in front of a table full of large assault rifles, pointing out locations on a paper map. A generator hums. All around us, splotches of forest dot the hundreds of islands that make up the archipelago of Petit-Saut, a watery ecosystem three times the size of Paris.

    Except Paris is 7,000 kilometres away from where I am, in Guyane, or French Guiana,a department of France in South America, just north of the equator.
