Birdwatch, March 2017

An active month for Steve Jones. An unexpected turtle appears, and interesting birds are coming and going on Hvar!

Steve reports from Dol:

March has proved to be far more fruitful than I was expecting going on last year's notes. Migrants seem to be arriving earlier. There were also several “firsts” for the island, that I have seen. This does not mean they haven‘t visited before, just that it's the first time I've seen them. I am guessing that some of these were passing on through, as a couple I have only glimpsed briefly, but also, fortunately, I have managed to photograph them.

If you are on Hvar, you will have noticed the birds singing, particularly as we hit the end of March. Around my house as I worked outside I was hearing Great Tit, Blackcap, Cirl Bunting, Blue Rock Thrush. I have also seen Blackbirds carrying food, so they were clearly feeding their young.

On to my sightings for the month, early March proved as expected: the odd Mistle Thrush, Fieldfare and Starlings were still around. I thought I saw a Song Thrush but all too quickly I’m afraid, and I don’t like to add any bird to my list of sightings unless I am 100% certain. On 3rd March I had superb views of the Hen Harrier in flight but that was the last time I saw it.

On 9th March I saw a Sandpiper of some kind – this was a first for me, and after scanning through the books and getting confirmation from a couple of friends, I am pleased to say it was, as I thought, a Green Sandpiper. I was expecting it to move on quickly, as the indications are they breed far further north, so I was pleasantly surprised to see this sandpiper numerous times during the month, even as late as 30th March.

Also on March 9th I saw a Turtle doing a bit of sun bathing. As with the Green Sandpiper it wouldn’t let me get too close before submerging, but I did manage to come up with a picture or two! I’m not 100% sure on the ID but as far as I can tell it is the “Yellow Bellied Slider”. My guess is this was a pet at some point that has been deposited in the pond.*(see footnote)

On the same day I managed a very brief glimpse of a Stonechat, but as I have not seen one since, I suspect this may have been passing through. On March 10th I saw a Sardinian Warbler, once again a puzzle. I’m not sure whether or not this was passing through, I have suspected they may over-winter on Hvar, albeit in very small numbers. On 11th March I saw my first Wheatear, no time for a photograph at the time, but I managed several shots towards the end of the month.

On 19th March I went to Humac early just to see if there was anything different calling that I am not hearing on my patch, but in fairness I was pretty disappointed. There were numerous Chaffinches singing, the odd Great Tit and a solitary Robin. So back down to the airfield vicinity and my first Corn Bunting of the year, also a Heron and two Grey Wagtails. Just as I was leaving at 09:30, I spotted my first Swallow of the year flying over the pond. The Green Sandpiper was still there, as well as the striped turtle / terrapin. (Some of the species I am picking up here are also being sighted in the UK now – such as Sand Martin, Cuckoo, Swallow).

20th March: Great Tits calling all over the place, but I haven't managed to take a decent photo of any. In the morning I thought I heard a Nightingale. It was only singing intermittently, which might be a sign that it had just arrived.

On 22nd March I thought I heard the Blue Rock Thrush. I didn’t see one at all last year, so I was not 100% sure but as the month progressed i heard it again, whether another or possibly the same one calling very near my house, especially on March 31st, when he was very obliging!

Also on 22nd March I saw a male Reed Bunting, not quite in full breeding plumage. Once again I suspect it was just passing through, as it was another first for me on the Island. I also heard a Greenfinch in Dol on the same day.

On 26th March I heard and saw a Sub Alpine Warbler, a bird which so far has escaped the camera. As they are territorial I picked up the call again on most mornings from the same location, and hopefully I will get a picture worth publishing some time.

27th March – without any doubt my best day bird watching since being here. I had seen all of the birds here before, but to get them all in one morning! I was very very pleased. My first Kestrel of the year, followed by Sub Alpine Warbler, Corn Bunting, Green Sandpiper, Serin, Yellow Wagtail and to cap it off as I was driving towards Stari Grad a Hoopoe right in front of the car.

On 30th March I saw an Alpine Swift. They were here last year, so they were not a new species for me, but nevertheless I was rather pleased to have seen it before a normal Swift.

If anyone is seeing anything else here please do let me know via the Eco Hvar contact email. I am particularly sticking to two areas only, so of course I don’t think for a second I am picking up everything on the island.

Finally, a selection of pictures taken in March: Greenfinch, Stonechat, Heron, Cirl Bunting (female), Reed Bunting and finally Wheatear.

FIRST SIGHTINGS IN MARCH BRING THE TOTAL FOR THE YEAR SO FAR TO 53

First sightings in March 2017

  • 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.

  • Project on ‘very poorly understood’ terrain and likely to pass through Rocky Mountain trench, which researchers say poses immense geological hazard

    When an earthquake in 2002 struck in a remote pocket of Alaska, the shock was the strongest ever recorded in the interior of the state. But, miraculously, an oil pipeline that crossed directly over the fault line was unscathed.

    Engineers behind the design of the 800-mile system were prepared. Knowing the high likelihood of seismic activity along the route, which bisected the Denali fault, they constructed sections where the pipeline rested on rail girders, allowing it to sway and shear without snapping.

  • The country is the world’s second-largest producer of the popular fish, and the biggest supplier to the US, but its farms are beset by accusations of dangerous labour conditions, antibiotic overuse and ecological harm

    Julia Cárcamo López’s house faces the sea, near enough to hear the gulls calling through the salt-encrusted windows. She lives in the small town of Maullín, on the edge of Chile’s Patagonia, an area where almost everyone works in the fishing industry.

    Outside, it is drizzling and the sky is darkening as she recalls 1 May 2019, one of the worst days of her life. “Two men knocked on my door and told me they had bad news: my husband had had an accident while working at sea,” she says. Since then, she has discovered that the accident seems to have been caused by negligence.

  • Banks of servers operating 24/7 generate massive amounts of heat, requiring power to run and cool them

    Datacentre power demand in Australia could triple in five years and is forecast to exceed by 2030 the energy used by electric vehicles.

    Datacentres now draw about 2% of electricity from the National Grid, about 4 terawatt hours of power. The Australian Energy Market Operator (Aemo) expects that share to rise rapidly – growing 25% year-on-year – to reach 12TWh, or 6% of grid demand, by 2030, and 12% by 2050.
