Birdwatch, August - September 2017

Well summer is over, birding-wise, and during the last three months, hopefully, birds have bred successfully on the island. I have certainly seen evidence of this, particularly recently, with good numbers of House Sparrows all around. Also frequently during the summer months I have seen birds carrying food to nests.

We are keeping an eye out for bats, as they have been noticeably fewer over the past few years. Happily, there have been more around this year. On August 9th, at dinner with nearby neighbours, I was pleased to see quite a few bats of different species swooping under the lights of their swimming pool. There was a Nightjar too.

With some difficulty and not terribly good images but I managed to photograph an adult and juvenile Golden Oriole which nested nearby in Dol – last heard in very early September, in Dol and also in Vrboska.

Mid-September and I have seen a few birds of prey passing through, several Harriers, Honey Buzzard (a bird watching friend visiting picked up on that – I’m not so sure I would have picked it out ). We also saw a Short-Toed Eagle on two different occasions at two different locations. Was it the same bird?? Perhaps.

After the much needed rain I visited the pond on Stari Grad plain every day to see if this would bring anything new in but still very quiet. I was seeing Whinchats and still Red Backed Shrike, an occasional Cirl Bunting calling whilst picking grapes on 14th September. Also on two different days a Sparrowhawk looking to feed but sadly on both days it was unsuccessful while I was there.

On September 13th down at the Vrbanj airfield I saw the first birds actually feeding on the ground, the recent rain had clearly softened the ground, providing some food, I counted 16 Hooded Crows, probably in the region of 200 House Sparrows in various flocks, a Hoopoe – you can clearly see from the picture how pale it looks in comparison to the arrival earlier in the year.

There were also a few Wheatear and seven Tawny Pipits, once again passing through. I wasn't totally sure of the identification, but three people I asked for help all confirmed.

On the same day whilst watching from my garden I saw several Blackcaps both adult and newly fledged birds feeding on the figs. Also several Spotted Flycatchers. Then, another first for me on the island, no doubt just passing through as there's been no sign of it since – a Wood Warbler. For ages I had been trying to photograph a male Blackcap and female, to show the difference between them for anyone who wants to identify them. In mid-September they were constantly feeding on the figs, albeit really difficult to catch on camera. But I was fortunate on the afternoon of September 15th. The picture clearly identifies a male and two females, female Blackcaps having the “brown cap”. Couldn’t be any better than that to make a comparison.

On September 17th two storks came to earth in Jelsa. Immediate steps were taken by bird-loving friends of Eco Hvar to ensure that they would be given appropriate food and kept as safe as possible. They settled into a comfortable routine over the next few days. The rain which came down on September 20th provided a good source of insects, which they devoured with gusto. They also clearly enjoyed the fresh fish meals which were being provided at intervals during the day. Storks are generally gentle birds, and intelligent. They quickly realized that shopping bags could be bringing them their mobile meals, so they were prone to advancing on any innocent shoppers who were trying toload their bags into cars parked nearby. The only worry was whether they would get too used to this luxury lifestyle to resume their long journey to Africa. However, this is not the first time storks have appeared in jelsa at this time of year, and they have always moved on after a while, so we shall see.

By September 21st most other migrating birds had headed off. I saw a single Swallow the day before. Out on my bike on the morning of the 21st, I saw Yellow Wagtails and Tawny Pipits frequenting the airfield getting ready to move on, while there was nothing at the pond again.

  • Landmark report calls for widespread air conditioning and says UK temperatures forecast to exceed 40C by 2050

    British homes will need air conditioning to survive predicted levels of global heating, the government’s climate advisers have warned in a report, as measures such as drawing curtains, opening windows and growing trees for shade are not likely to be enough.

    Air conditioning should be installed in all care homes and hospitals within the next 10 years, and in all schools within 25 years, according to the Climate Change Committee (CCC), which published a major report on adapting to the impacts of global heating on Wednesday.

  • For 150 years, the Mease had been altered by human hands, which destroyed habitats. But in 2013, a restoration project began – and now its wetlands are abuzz with wildlife

    ‘A noisy river is a healthy river,” says Ruth Needham of the Trent Rivers Trust (TRT). The Mease in the Midlands must be in fine fettle, then, as it gurgles merrily along. Sunlight glints off riffles in the water and shoals of fry dart past. Needham whips out her phone to video the tiny fish: “My colleagues will be jumping for joy to see them!”

    Needham has good reason to be buoyant. Last month, the Mease won the UK River prize 2026 – which was established by the River Restoration Centre in 2014 to acknowledge innovative projectsin recognition of the trust’s 13-year restoration campaign. “The prize has been a massive boost,” says Needham. “If we can get the Mease into better condition, we can improve other rivers, too.”

  • Chancellor’s planning shake-up would ‘reduce exposure from judicial review on all but human rights grounds’

    Rachel Reeves is ​preparing to announce a planning shake-up ‌that would fast-track clean energy ​and infrastructure projects by curbing judicial reviews, the ​Treasury said.

    The chancellor will propose that parliament should be able to designate and approve the most important clean energy projects as of “critical national importance”, as part of a wider package seeking to blunt the impact of the Iran crisis.

  • Vibrating flowers uses huge amounts of energy, forcing bees to choose which plants to visit and affecting which ones are pollinated

    Bees use as much energy collecting pollen through “floral buzzing” as they do taking off in flight, a study shows.

    Scientists have found the vibrations bumblebees use to shake pollen loose from flowers are among the most exhausting behaviours they perform, forcing bees to “carefully choose” which flowers are worth visiting.

  • National Audit Office says potential benefits are ‘considerable but uncertain’ while risks are ‘immediate and substantial’

    The cost of the government’s £38bn nuclear plant in Suffolk is subject to “significant uncertainty” and may outweigh the benefits for UK households until at least 2064, according to the government’s spending watchdog.

    The National Audit Office (NAO) has warned that although the potential benefits of the Sizewell C nuclear plant are considerable, they remain uncertain. The risks, however, are “immediate, substantial and borne by the public”.

  • Need for minerals, biofuels and pulp adding to pressures from ranching, monocrops, oil and logging, analysis finds

    The growing extraction of rainforest resources is pushing the Amazon and similar biomes towards breaking point, a report has shown.

    Fresh demands for critical minerals, biofuels and pulp – used in fast fashion, processed food and packaging – are compounding existing pressures from cattle ranching, monocrops, oil and logging, the analysis finds.

  • Study of Channel finds levels of toxic Pfas in Solent at 13 times safe limits in some places, with much coming from treated sewage

    Scientists have found high levels of toxic Pfas, or “forever chemicals”, in soil, water and throughout the marine food chain in the UK’s Solent strait, including at protected environmental sites, according to a new study.

    In some samples, pollution was 13 times the safe threshold for coastal waters. Others, which were below legal limits for individual chemicals, failed tests for combined toxicity.

  • Galegine compound in plant formed blueprint for metformin drug, but without the toxic side-effects

    Goat’s rue or French lilac, Galega officinalis, is a wild plant and often grown in gardens for its clusters of attractive lilac or white flowers. For a long time the plant was also used to treat diabetes. Its key ingredient was later identified as galegine, which lowers blood glucose levels but has toxic side-effects.

    Eventually galegine led to the development of the synthetic drug metformin, now the classic treatment for treating diabetes by controlling blood sugar. Metformin has none of the toxic side effects of galegine and is now one of the most prescribed drugs in the world. But for many years metformin was vilified and banned in many countries because of its association with galegine.

  • As new settlers clear their forest habitat, the apes are coming into conflict with humans. But simply moving them to another part of the forest may not be the answer

    The banana skins were an ominous sign. As was the branch that had been broken off to get to the fruit. Had Edi Ramliwalked into the forest, he might have seen scattered balls of bark that had been ripped off trees, chewed like gum, then spat out. It takes a powerful jaw to do that. Closer to Edi’s home, there was an intricate construction of bent and broken branches high in a tree. The nest.

    It was October, the fruiting season. The pile of half-eaten bananas was less than a minute’s walk from where Edi and his family slept. He felt nervous. He got on with his day. He picked sweetcorn and sold it at the market. He bought a carton of chocolate milk and biscuits for his grandson. He and his wife, Siti Munawaroh, ran the farm with their three adult children. They prepped the land, sowed seeds, tended crops. Survival depended on what they could grow.

  • Like many informal settlements, communities that have sprung up on the edges of Ayacucho in the Andes are on the frontline of extreme weather events

    In December 2009, a late‑afternoon storm unleashed torrential rain over Ayacucho, in Peru, hitting poor hillside neighbourhoods hard. The deluge overwhelmed drainage systems, turning streams into lethal flows of mud, stones and debris that flooded houses and streets and trapped drivers at a busy junction.

    Ten people died, 18 were injured, and 530 houses were destroyed or damaged, according to a government inquest. “It was a disaster,” recalls Edgar Castro, a leader in Ayacucho’s largest informal neighbourhood, Mollepata.
