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.

  • As this year’s invertebrate of the year competition launches, we join scientists studying last year’s winner

    Witek Morek is closely inspecting an old brick-and-flint wall on the Cambridgeshire campus of the Wellcome Sanger Institute.

    “We are going to use a very advanced tool designed by bioengineers and evolved over millions of years – the human hand – and grab some moss, and put it in an envelope,” he says.

  • Public health authority says 2,025 excess deaths probably an underestimate and that it expects toll to rise further

    The number of deaths recorded in France surged by nearly 30% during the hottest week of the record-breaking heatwave that scorched much of Europe last month, the public health authority has said, adding that it expected the toll to rise further.

    Public Health France said on Friday there had been “an increase of 29.1%, corresponding to 2,025 additional deaths compared with the previous week”. It said the figure was probably an underestimate and “mortality will rise further”.

  • Guardian recreates audio landscape of past filled by loud morning symphony before 73m wild birds were lost

    Imagine a deafening abundance of birdsong so loud it wakes your children at dawn; the chirrup of house sparrows, the chattering of starlings, the melody of the wren, and the clear high-pitched flute of blackbirds saturating the garden, reverberating around your local park, dominating your neighbourhood from early morning to evening twilight.

    So loud is the song of the thrush that the naturalist and ornithologist WH Hudson wrote in 1919 that he was grateful when observing one that it was perched on a tree at a distance from his home, “so that when I woke at half past three or four o’clock, the shrill indefatigable voice came in at the open window, softened by distance and washed by the dewy atmosphere to greater purity”.

  • Hitchin, Hertfordshire: The broad-bodied chaser is often the first to arrive at a new pond, and sure enough, I spot an exuvia clinging to a leaf blade

    The hole in the nest box on our house wall is all mouth. A sparrow chick on the cusp of fledging has thrust its head out, beak open, displaying an orange gape ringed with a creamy-yellow flange. It’s an unmissable prompt for the parents: Insert Invertebrates Here.

    I’m watching the spuggies from behind the pond, where I’m perfectly positioned to see the aftermath of another emergence. At the top of a bur-reed, the hollow legs of a dragonfly exuvia (the shed larval casing) grip the leaf blade, while a split in the cuticle shows where the adult has pushed through its exoskeleton.

  • Participant-led YPS scheme creates green projects while providing summer jobs in country with high youth unemployment

    Oona Verveld and Clara Vikberg have just secured their first paid summer jobs. While their peers are mostly limited to entry-level positions in retail or fast-food restaurants, the 18-year-olds are some of the first among their generation to have landed a new type of role: young planetary stewards.

    “Someone came up with the simple idea that, since young people clearly need jobs, why not create them?” says My Sellberg, the project manager and programme lead for regenerative development at Upplandsbygd, a non-profit based north of Stockholm. “The strongest objective was to inspire hope for the future among our young residents.”

  • In one area 76% of fishing boats were followed, with baby dolphins learning the technique from their parents

    Bottlenose dolphins in the Adriatic are increasingly following trawlers to scavenge for food, with baby dolphins learning the technique from their parents, a study has found.

    “These days the easiest way to find [bottlenose dolphins] is to look for trawlers,” said Giovanni Bearzi, a co-author of the study and the president of Dolphin Biology and Conservation in Italy. “Many of them are followed by the dolphins that go to forage and scavenge in their wake.

    Every year, millions of visitors from across the globevisit Jamaica to enjoy its gorgeous beaches, fuelling a multibillion dollar tourism industry. But, in recent years, its picture-perfect coastlines have become a battleground for access after successive governmentsprivatised its shorelines to support the country’s thriving all-inclusive hotel industry.

    The complex row, which has seen protesters clashing with police and campaigners tearing down barriers around privatised properties, is now playing out in the country’s courts. We take a closer look at each side’s case, and what’s at stake.

    European heatwave is worst ever and impossible without climate crisis, scientists say

    A sad inevitability’: after decades of climate warnings, why is Europe so unprepared for rising heat?

    ‘But we’re just 1% of emissions’: do smaller countries’ climate efforts matter?

  • Shifting demands and political ideology have left the industry vulnerable to global competition from cheap Chinese cars

    Earlier this month, an intriguing new Detroit-based electric vehicle startup hit the market – Slate Auto, a Jeff Bezos-backed venture offering something US buyers rarely see these days – a pick up truck billed as “affordable”.

    Its base price is $24,950, making it one of the lowest-cost autos in the US market and close to half the price of the average new vehicle. But as the US contends with sharply rising auto costs, even Slate may be getting left behind in the global electric vehicle (EV) transition. The global EV industry is entering a golden age powered by cheap Chinese cars that can be bought for as little as $10,000.

    There is a rising stink around rubbish removal in Australia. Councils around the country are looking for ways to divert more organic waste away from landfill.

    Australians generate about 14.6m tonnes of organic waste each year – mostly garden clippings, food scraps and timber. About half of it is collected from households in kerbside bins.

  • Sound of thunder varies depending on distance of listener from lightning as atmosphere muffles and absorbs sound

    A bolt of lightning heats the air almost instantly to as high as 30,000C, causing explosive expansion and a supersonic shock wave that becomes thunder. What that thunder sounds like to a listener depends largely on where they are.

    Nearby lightning produces a distinctive snap or crack, or a startling explosive boom. Large, complex lightning with multiple segments generates a peal of thunder, a series of booms of different pitches as the sound from each of the segments reaches you in turn.
