Birdwatch, May 2017

After a brief absence from the island, Steve Jones caught up with the bird activities in May. Lots of early-summer action going on!

Well, I came back from the UK on 7th May, and there were audible signs of new arrivals, most notably the Golden Oriole. Whilst in the UK I was told the Bee-Eaters arrived in Pitve on 3rd May. Last year my first sighting of both Bee-Eater and Cuckoo was 10th April.

In fact from the house on 7th I heard Golden Oriole, Hoopoe, Turtle Dove, Blue Rock Thrush, Blackcap, Cirl Bunting and Cuckoo.

8th May, This was my first day back at the pond and, being car-less I did a 14km cycle in the morning, starting out just after 0700hrs. There were plenty of Bee-eaters, I counted 52 on my travels in two areas. Also that morning there was a Turtle Dove (they had been just arriving during the third week of April), and I saw Corn Bunting, Greenshank and Wood Sandpiper, Red Backed and Woodchat Shrike.

 I've been seeing more woodchat than red-backed shrikes this year.

A special treat was a very pleasing new arrival for the Island, my first sighting here of a Spoonbill.

10th May brought in another new wader for the count - Dunlin

I was surprised to see a solitary Starling in Mid May, a bird I was expecting to see more of. They made their first appearance in early February, stayed for a short while and then moved on. I was seeing all the usual species every day, but 13th May brought in a Whitethroat. I saw one last year in Split but this was a first for me on the island. Then I saw my first dragonflies on the wing on 14th May.

18th May: I was out at 5am this morning, trying to photograph some Bee-Eaters from two sandbanks, but saw nothing. Clearly they are not roosting there, and yet I have seen groups of up to 50 flying about. Maybe later in the day is the right time to see them. However, I did see a Little Ringed Plover, which I also saw last month, and this time I managed to get a decent photograph of it.

Going out every day to the same place I was seeing nothing new until the 19th May, when I got three new species: Spotted Flycatcher, Black Headed Bunting and a new one for me on the Island – Purple Heron. (On 18th April I had made a note to myself that I might have seen this, but the sighting was all too brief, so I sort of dismissed it). Anyhow the Purple Heron, which was about for two or three days, brought the count for the year to just over 80, so I was very pleased with that.

Continuing to go the pond not far from the airfield every day, I have been seeing a lot of Woodchat Shrike this year, seemingly far more than in previous years. Waders seemed to be hitting the pond most days, never in great numbers, but some two or three were appearing most days up to 28th. There was a Black-Headed Bunting calling nearby and several Linnets about. Unfortunately a decent picture of the Linnet escapes me.

30th May. I have kept varying my times going out just in case it might bring different species, but it hasn't made too much difference. The Nightingale is hardly singing at all now, and with only three weeks to longest day that will signal the end. I’m not into finding nests with young, but I have seen evidence of birds feeding their young. I suspect the last of the waders have moved from the pond, as I have not seen anything in three days now. Blackbirds are singing again as are Blackcaps. A couple of Corn Buntings were singing again this morning, and I've been hearing the Black Headed Bunting periodically.

Finally, 30th May saw me a get a reasonable picture of a Cuckoo at last, still some distance away, but for those of you who have heard but not seen them, this is for you.

With the few new species spotted this month, there are 83 in total now for the year so far.  There are also a couple I haven’t mentioned in writing, as I couldn't get decent enough photographs to highlight them. They tend to be a bit nondescript. The Spotted Flycatcher and Garden Warbler for example, and the Spanish Sparrow is another one which is difficult to pick out.

I have a potential new wader which I photographed a week ago, but I am not entirely convinced that it is different from the Little Stint which is already on the list. When these birds are only 18cm high and you are seeing them from a distance, plus they are just coming into breeding plumage, it makes ID ( for me) difficult. But everything I have listed I am 100% happy with.

Postscript: a female cuckoo made its presence known with its unusual call on May 20th, just behind my house in Pitve, and again for three days after that. I haven't heard her since, so I presume she concluded her sneaky egg-swapping business and then flew off to pastures new! VG June 12th 2017.

  • Study links rapid growth of ocean macroalgae to global heating and nutrient pollution

    Scientists have warned of a potential “regime shift” in the oceans, as the rapid growth of huge mats of seaweed appears to be driven by global heating and excessive enrichment of waters from farming runoff and other pollutants.

    Over the past two decades, seaweed blooms have expanded by a staggering 13.4% a year in the tropical Atlantic and western Pacific, with the most dramatic increases occurring after 2008, according to researchers at the University of South Florida.

  • Experts call for tighter regulation as GPS tracking reveals how people’s behaviour affects the lives of some of the world’s largest birds

    Many people look up to admire the silhouette of raptors, some of the planet’s largest birds, soaring through seemingly empty skies. But increasingly, research shows us that this fascination runs both ways. From high above, these birds are watching us too.

    Thanks to the development of tiny GPS tracking devices attached to their bodies, researchers are getting millions of data points on the day-to-day lives of these apex predators of the skies, giving us greater insight into where they hunt and rest, and how they die.

  • Food produce and other waste has been littering Sussex coastline as capsized shipping containers wash ashore

    Coral Evans was walking along the beach in Brighton on Tuesday evening when she came across an unfamiliar sight.

    “Hundreds of dust masks had washed up, along with single-use plastic gloves and cans of dried milk,” she said. “It was odd to see in winter – because nothing surprises us in summertime with the amount of people on the beach.”

  • There are so many koalas in some places that food is the issue – while elsewhere populations are threatened by habitat loss. And there are no easy fixes

    On French Island in Victoria’s Western Port Bay, koalas are dropping from trees. Eucalypts have been eaten bare by the marsupials, with local reports of some found starving and dead. Multiple koalas – usually solitary animals – can often be seen on a single gum.

    Koalas were first introduced to French Island from the mainland in the 1880s, a move that protected the species from extinction in the decades they were extensively hunted for their pelts. In the absence of predators and diseases such as chlamydia, the population thrived.

  • Frome, Somerset: Get tuned in to the river’s sounds and you’re treated to a symphony of noise, from susurrating hisses to great belches

    After three decades living alongside mute waterways in East Anglia, with their soundless glide over clay, I am learning a liquid language here, and all its boulder dialects, as our winter‑filled local stream gushes down its limestone gorge.

    My fellow country diarist and wild swimmer Amy-Jane Beer shares my passion for river music. She tells me of her compulsion to listen when fresh water is given a voice by coming to the surface.

  • Tony Cholerton created Robovacc to inoculate a timid tiger at London zoo – but says it could administer jabs to badgers

    It began with the tiger who wouldn’t come to tea. Cinta was so shy that she refused to feed when keepers at London zoo were around, and staff wondered how they would ever administer the young animal’s vaccinations without traumatising her.

    So Tony Cholerton, a zookeeper who had been a motorcycle engineer for many years, invented Robovacc – a machine to quickly administer vital jabs without the presence of people.

  • The cost of producing milk is higher than that being paid by milk processors, leaving farmers operating at a loss

    “Every morning that I roll out of bed at 4.40am, I know I’m losing £1,800 that day, just by getting up.” This is the stark daily reality for Paul Tompkins, as he and his fellow dairy farmers struggle in the face of plummeting milk prices.

    Tompkins, who is the third generation to run his family’s 234-hectare (600-acre) farm in the Vale of York, can produce milk for about 40p a litre from his 500-strong herd of black and white Holstein cows. However, he is being paid only 29p a litre by his milk processor, leaving him operating at a loss, despite trying to run his business as efficiently as possible.

  • A return to nuclear power is at the heart of Japan’s energy policy but, in the wake of the 2011 disaster, residents’ fears about tsunamis, earthquakes and evacuation plans remain

    The activity around the Kashiwazaki-Kariwa nuclear power plant is reaching its peak: workers remove earth to expand the width of a main road, while lorries arrive at its heavily guarded entrance. A long perimeter fence is lined with countless coils of razor wire, and in a layby, a police patrol car monitors visitors to the beach – one of the few locations with a clear view of the reactors, framed by a snowy Mount Yoneyama.

    When all seven of its reactors are working, Kashiwazaki-Kariwa generates 8.2 gigawatts of electricity, enough to power millions of households. Occupying 4.2 sq km of land in Niigata prefecture on the Japan Sea coast, it is the biggest nuclear power plant in the world.

  • Pioneering scheme hopes species that thrived for thousands of years in Irish waters can do so again

    The dinghy slowed to a stop at a long line of black bobbing baskets and David Lawlor reached out to inspect the first one.

    Inside lay 60 oysters, all with their shells closed, shielding the life within. “They look great,” beamed Lawlor. So did their neighbours in the next basket and the ones after that, all down the line of 300 baskets, totalling 18,000 oysters.

  • Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences

    On one side of Dr Ben Galton-Fenzi’s view across the vast Totten ice shelf, the sun sat low on the Antarctic horizon. On the other, a full moon.

    The ice shelf is “flat and white”, says Galton-Fenzi. “If there’s cloud around, you lose the horizon.”
