Black-winged stilts at Soline

A rare sighting of an endangered species, with thanks to Alison and Bojan Bujić.

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.

  • Young people living by the sea are often in some of the most deprived areas of the country, but they say they want the chance to thrive. The Guardian is embarking on a year-long series to tell their stories

    On the beach in Weston-super-Mare, on the south-west coast of England, there is a hint of a chilly breeze in the air but the sun is out and the clouds are faint, whispy streaks across a pleasantly blue canvas. A couple of fishing boats are tethered to the harbour wall and a lone man with a metal detector wanders slowly along the sand. A small shop selling ice-creams has a few takers, despite the nip in the air.

    Yet behind its low-key but welcoming seafront lies the evidence of a cloudier, more complex reality.

  • A14 in Cambridgeshire promised biodiversity net gain of 11.5%, but most of the 860,000 trees planted are dead. What went wrong?

    Lorries thunder over the A14 bridge north of Cambridge, above steep roadside embankments covered in plastic shrouds containing the desiccated remains of trees.

    Occasionally the barren landscape is punctuated by a flash of green where a young hawthorn or a fledgling honeysuckle has emerged apparently against the odds, but their shock of life is an exception in the treeless landscape.

  • Diquat is banned in the UK, EU, China and other countries. The US has resisted calls to regulate it

    The herbicide ingredient used to replace glyphosate in Roundup and other weedkiller products can kill gut bacteria and damage organs in multiple ways, new research shows.

    The ingredient, diquat, is widely employed in the US as a weedkiller in vineyards and orchards, and is increasingly sprayed elsewhere as the use of controversial herbicide substances such as glyphosate and paraquat drops in the US.

  • Exclusive: Letter to government says lower prices for repaired goods would cut waste, create jobs and help households save money

    Ministers are facing fresh calls to scrap VAT on all repaired and refurbished electronics, with businesses, charities and community groups arguing the move would help households cut costs and stop electrical goods being binned prematurely.

    In a letter to the environment secretary, Steve Reed, the signatories say that removing VAT on repaired electronics should be part of a wider push to cut waste, extend the life of products and develop a “truly circular economy”.

  • Storms that led to deadly flash floods were heightened by moisture from the remnants of Tropical Storm Barry

    Texas was hit by catastrophic flash floods on Friday after powerful thunderstorms unleashed torrential rainfall across the region. Kerr County, in the south-central Hill Country, received more than 300mm of rain in just a few hours.

    As of Sunday evening, at least 68 people had been confirmed dead, and 28 girls were missing after flood waters tore through a summer camp.

  • Allendale, Northumberland: How better to use a reluctantly felled tree than to turn it into a wind-filtering wildlife habitat, practical barrier and cost-free fence?

    A ghost tree shines silver against the greenery of the hillside wood. Sheathed in silk from its trunk to the tips of its branches, this bird cherry has been completely defoliated by caterpillars. These are the overwintered larvae of bird cherry ermine moths, Yponomeuta evonymella, which, having spun their protective webbing, can devour the leaves, safe from blue tits and parasitic wasps, before pupating. Some weeks later, thousands of slender moths will emerge, their white wings speckled with tiny black dots.

    Bird cherries abound in this valley. Fast-growing, often multi-trunked trees, one once stood by our boundary wall that had grown so tall it rocked in the winds, the movement of its roots bringing down the stonework. When it demolished the wall for the fifth time, we reluctantly had it felled in late winter before birds started nesting. As well as logs, this left a huge pile of brash.

  • The women are raising larvae of the endangered Taylor’s checkerspot for release into the wild

    Trista Egli was standing in a greenhouse, tearing up strips of plantain and preparing to feed them to butterfly larvae.

    Of the many things the team here has tried to tempt larvae of the Taylor’s checkerspot – a native of the Pacific north-west – with, it is the invasive English plantain they seem to love the most.

  • The brilliant planet will move across the invisible line between the pair and appear 3 degrees away from the star Aldebaran

    This week, Venus will pass through the so-called Golden Gate of the Ecliptic. Although the name has risen to prominence with science popularisers in recent decades, its exact origin is unknown.

    It references two star clusters in the constellation Taurus, the Bull. The Hydes and the Pleiades lie on either side of the ecliptic, which is the plane of the solar system. As such, the sun, the moon and the planets all follow this line in their passage through the sky. The constellations the ecliptic passes through are known as the zodiacal constellations, referred to in popular culture as the signs of the zodiac.

  • Not only is nuclear essential if we want to reach net zero – it’s the key to tackling poverty, too

    Money can buy comfort, but energy makes comfort possible in the first place. Energy is the great enabler of the modern world. It connects the globe by moving people and hauling goods. It loosens the grip of the weather by warming our homes in winter and cooling them in summer. It forges the steel that raises our cities and synthesises the fertilisers that keep half the world’s population from starvation. It increasingly empowers us by electrifying the technologies we rely on daily.

    It is also the great enabler of socioeconomic development. Monetary wealth and energy abundance move in lockstep: plot a graph of GDP per capita against energy consumption per capita, and you’ll draw a straight line. Low-energy, high-income nations do not exist. Prosperity and energy are inseparable; you cannot have one without the other.
