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.

  • Fish levels fall by 7.2% with as little as 0.1C of warming per decade, northern hemisphere research shows

    Chronic ocean heating is fuelling a “staggering and deeply concerning” loss of marine life, a study has found, with fish levels falling by 7.2% from as little as 0.1C of warming per decade.

    Researchers examined the year-to-year change of 33,000 populations in the northern hemisphere between 1993 and 2021, and isolated the effect of the decadal rate of seabed warming from short shifts such as marine heatwaves. They found the drop in biomass from chronic heating to be as high as 19.8% in a single year.

  • Researchers say solitary bottlenose has adapted well to city waters, but tighter controls on boat traffic and human behaviour are needed

    Italian scientists monitoring the movements of a dolphin in the Venice lagoon have said humans are the ones who need managing, rather than wildlife.

    Known as Mimmo, the bottlenose dolphin has been spotted on several occasions since it made its first appearance in June last year, prompting a research team from the University of Padova to spring into action.

  • UK Climate Change Committee voices concern over Scotland’s progress on decarbonising buildings and reliance on unproved technologies

    Scotland has finally produced realistic short-term plans on cutting its climate emissions, but there is “real concern” about the credibility of its overall strategy, the UK’s climate policy watchdog has found.

    Nigel Topping, the chair of the UK Climate Change Committee, said there were “flashing amber lights” about the quality and seriousness of some of the Scottish government’s medium- and long-term proposals to reach net zero by 2045.

  • Walthamstow Wetlands, London: They’re professional skulkers, loud but highly elusive. And yet there one is, out of the reeds, to be remembered for ever

    It’s weather you’d emigrate to avoid. Gloomy and cold – Tupperware sky and drizzle in the air. But tranquil, at least. Small mercies. Walthamstow Wetlands – a 211-hectare nature reserve centred on 10 reservoirs in north-east London. Jewel in the Lee Valley’s crown, and as good a place for waterbirds as any in the capital.

    Six tufted ducks drift across – a posse of monochrome floaters on a mission to nowhere. A little grebe – floating powder puff – does its trademark jump-and-dive, surfacing 30 seconds later, 25 yards to the left of where I expected. Extreme peace descends on me. Birdfulness, the best way to be.

  • Gene-altering chemicals found in humpback dolphins and finless porpoises, raising alarm they may end up in human food chain

    Toxic e-waste chemicals from television, computer and smartphone screens have been found in the brains and bodies of endangered dolphins and porpoises in the South China Sea.

    Research published in Environmental Science & Technology detected significant levels of gene-altering liquid crystal monomers (LCMs) in Indo-Pacific humpback dolphins and finless porpoises.

  • Thousands more people across Devon and Cornwall could join case against water firm

    A group legal claim against South West Water alleging sewage pollution into coastal waters is harming businesses and individuals has been expanded across Devon and Cornwall.

    Thousands more individuals could now join the first environmental community group legal action against a water company over the impact of sewage pollution.

  • Coalition government agrees to remove parts of controversial law and allow homes to rely on fossil fuels

    Germany’s coalition government has been accused of abandoning its climate targets after agreeing to scrap parts of a contentious heating law mandating the use of renewables in favour of a draft law allowing homeowners to rely on fossil fuels.

    While the previous law required most newly installed heating systems to use at least 65% renewable energy, often with a heat pump, the amended legislation will allow households to keep using oil and gas.

  • He was at the heart of 1960s counterculture, then paved the way for the libertarian mindset of Silicon Valley. At 87, Brand is still keen to ensure the world is maintained properly – not just today, but for the next 10,000 years

    Stewart Brand thinks big and long. He thinks on a planetary scale – as suggested by the title of his celebrated Whole Earth Catalog – and on the longest of timeframes, as with his Long Now Foundation, which looks forward to the next 10,000 years of human civilisation. He has had a lifelong fascination with the future, and anything that could get us there faster, from space travel to psychedelic drugs to computing. In fact, he was arguably the bridge between the San Francisco counterculture of the 60s and present-day Silicon Valley: in his commencement speech at Stanford University in 2005, Steve Jobs eulogised the Whole Earth Catalog and Brand’s philosophy, and echoed its farewell mantra: “Stay hungry. Stay foolish.”

    You could say that Brand has also lived big and long. He is now 87 years old, in the final chapters of an eventful and adventurous life that has crossed paths with some of the most consequential events and figures of his era. He has been a writer, an editor, a publisher, a soldier, a photojournalist, an LSD evangelist, an events organiser, a future-planning consultant, even a government adviser (to the California governor Jerry Brown in the late 70s). “There was a time when people asked me, ‘What do you do?’ I said, ‘I find things and I found things,’” says Brand, as in he is a founder. He is speaking from a library where he likes to work in Petaluma, California, not far from his houseboat in Sausalito. “I’m always searching for good stuff to recommend, and good people.”

  • Armed groups and a state-owned refinery’s oil leaks have displaced Barrancabermeja’s fishing community and poisoned a paradise once full of manatees and jaguars

    Standing on her wooden canoe, a machete in her hand, Yuly Velásquez hacks away at reeds matted with blackened sludge. Close by, a burst oil pipe has released a slick of crude into the San Silvestre wetlands in Barrancabermeja, Colombia’s oil city, choking the water and its wildlife.

    “The destruction is immense,” says Velásquez, president of Fedepesan, a sustainable fishing organisation. “For the fish, the animals and flora, it means immediate death.”

  • The Belgian ceremony attracts beekeepers from the Netherlands, France and Germany keen to boost dark bee numbers and stop the spread of the hybrid honeybee

    Every summer, 1,000 virgin queens descend on the Belgian town of Chimay. During the “wedding flight”, a male attaches to the female. His endophallus (penis equivalent) is torn off and he falls to the ground and dies. Mission accomplished.

    Beekeepers come and pick up their fertilised queens in small colourful hives, driving them back home, sometimes more than 300km away. They will use the genetic material gathered in south Belgium to build new colonies in the Netherlands, France and Germany.
