Alison Bujić by e-mail 22nd April 2016. We have just returned from a lovely walk around the Soline peninsula where Bojan spotted a pair of Black-winged Stilts standing motionless in a rock-pool.  We watched them for some time with binocs, hoping to see them catch something but in the end we gave up.  They are stunning to look at with their long bright red legs - do you or your bird-expert friend know about them and are they unusual here? We had no idea what they were until we looked them up when we came home.

 

Reply from Steve Jones, April 22nd 2016: I haven't seen them here but am familiar with the bird. Soline is a bit out of "my patch", all of my watching is in and around Dol/Stari Grad due to time restrictions. I will make a note - even when I was "holidaying" I hadn't come across them before. So a good record. Looking at one of my books I would suggest quite unusual/rare to see here but certainly not impossible and I would have no reason to doubt it as they are quite distinctive.

The Croatian State Institution for Nature Protection classifies the black-winged stilt as “critically endangered“. The description certainly illustrates why this bird should be protected: 

“The black-winged stilt is a very social bird. Outside of nesting season, they remain in small flocks of 5 to 10 birds, and are occasionally included in mixed flocks with other shorebirds. They are rarely solitary. Large flocks are common at resting areas. They nest in colonies, usually containing 10 to 40 pairs. They are monogamous, with the relationship between partners lasting one nesting season. They build their nests on the ground, on islands or spits surrounded by shallow water, occasionally even on dry ground. Building the nest, incubating the eggs and raising the young is the task of both parents. The brood usually consists of four eggs that hatch in 22-23 days, and the young birds are independent within 2 to 4 weeks.

The black-winged stilt began to nest in Croatia at the end of the 20th century, and today, few of these birds nest at only a few known localities.”

 Alison, April 22nd 2016: Thank you - this is really interesting and confirms Bojan's suspicion that they may have strayed from the Neretva delta area.

  • 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.”

  • Ukrainians lament appalling toll of fighting on their country’s bird population

    Russia sent kamikaze drones to attack the Ukrainian city of Zaporizhzhia in February. They hit buildings and killed several people. One unreported victim of the bombardment was a male long-eared owl, blinded in one eye and found with a badly broken wing. A passerby scooped up the stunned bird, put him in a box and took him to the city of Dnipro.

    The owl – nicknamed Sunny – is now recovering in a cosy room belonging to Veronica Konkova. No longer able to fly or hunt, Sunny instead hops around.

  • 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 has 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 soften the economic blow from the Iran crisis.

  • Young Americans are suing the president for violating rights with executive orders that fuel the climate crisis

    Eva Lighthiser was at a dorm party on her Colorado college campus last month when she had to call it an early night.

    “I said, ‘Hey, I’ve got to go to bed, I’m flying out to Portland tomorrow,’ and then of course follow-up questions get raised,” she said. “I’m like, ‘Well, it’s a lot to explain.’”

  • ‘Floral buzzing’, the vibrations bees use to shake pollen loose from flowers, takes more energy than previously thought

    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”.

  • 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.
