Birdwatch, April 2019

Well, as we approached the end of another month, the birds kept arriving.

When I was typing this on the 26th April I was at 67 species for the year. This time last year I note it was 78 species. I believe this was due to the low levels of water at the pond during February and March, as I reported previously. The heavy rain we had in April put some water back and indeed a few waders were to be seen, but nothing like the levels of 2018. On April 2nd I went down to the pond in the afternoon, and saw my first Greenshank of the year. It made me think how much I might be missing as the birds pass through. I had already visited the pond at 06:40, so it was just by chance I went again in the afternoon. Perhaps I ought to stay for a whole day!

Corn Buntings were singing regularly as was the Sub-Alpine Warbler and occasional Sardinian Warbler. I was hearing up to three Cuckoos for some time, but their calling was not consistent and at the time of writing I hadn't heard them for  a few days. Great Tits built a nest in my garden which was pretty well complete by April 2nd. I set up a webcam on a nearby tree so that I could see the parents going in and out, but I was careful not to intrude, I didn't want to jinx anything!

I have been seeing far more Hoopoes this year than in any previous year, one morning I saw five, three at the same time, and two at a different location, so I know for certain there were five separate birds. On 10th April I had a new experience on Hvar: a peacock suddenly crossed my path! I had been told by a hunter during the winter that there was a peacock about in a certain place over a few days, but when I went to see, there was no sign of it. And then, as I was heading out towards the pond on the morning of the 10th, there it was in front of me. I managed a quick picture, but it had hopped over a wall and disappeared as I tried to get a better one.

In Jelsa on April 17th I saw two House Martins on a nest  near the main car park. They didn't look like young birds, maybe they were just making use of an old nest.

I had been worried about the Great Tit nest, as the parents were not visiting it. However, on April 16th the mother was sitting on her eggs again in the morning. I was thinking the cats might have had her as I had seen two different cats camped on top of the bird box. Anyhow all was looking well. By April 17th my Great Tit was definitely back on the eggs, and I was pleased to see that if I got too close to the box she hissed at me.

Generally during the month I didn't see great numbers of any single species, apart from Swallows, but generally the birds were trickling through. However, on several occasions in April I saw up to 30 Yellow Wagtails (I included a photo of one in the March report). There are a lot of variations within this species, and I believe I have seen three different species here.

By April 17th recent rains had put some water back into the pond, and I saw up to four waders. I was particularly fortunate this month to have had a very obliging Little Egret at the pond. Often any sight of movement or even my car is enough to put some species up to flight, particularly the small waders. In the photo you can clearly see the yellow feet which are used as a lure to attract fish.

Without any doubt the highlight for me was a Wryneck. I had never seen one before although was aware of them. I was out on my bike approaching Vrboska from Jelsa and I heard a call I was not familiar with. It was on the opposite side so I was hoping I could get there before it flew off. Sadly I was looking into the sun but I managed to take a very poor photograph which was not really good enough to identify by. It flew off after a couple of minutes. On getting back home I described the call to a friend in the UK who immediately suggested Wryneck. I went back on two more occasions with no success. That said, when I was at Maestral in Stari Grad on the morning of April 25th, I heard the call again, so I dropped everything and just managed to get a departing shot - a poor photograph, but just enough to identify. It was a shame it didn't stay around longer, but at least I got a glimpse of it.

I was told that the Scops Owl was making its presence felt all day every day in Pitve this month, as well as after dark, which seems slightly unusual. I have heard it calling during the day on occasion, and a couple of years ago managed to capture some daytime photographs.

On April 26th, I was out very early in the morning. Apart from the non-stop Nightingale, the first bird I heard in Dol was the Golden Oriole, which must have arrived in the night, as I had not heard one up to then. Also, very pleasingly, after three unrewarding  trips to Jelsa during the week, at last I witnessed the arrival of the Bee-Eaters. They were quite active, but I did manage to picture one as it landed.

By April 26th all ten Great Tits had hatched in their nesting box and were very busy feeding. I opened the box for a quick look, and there they were, two days old, with their mouths open. They will have fledged by the time I return from my travels, so I won’t actually know how many get away. What has proved interesting is that the nest box works ( I was always worried about local cats, particularly when I have seen two different ones sat on the top of the box with the mother inside. This might also prove interesting when they are both feeding young.) Also that it doesn’t have to be high, mine is only about 1m 60cm off the ground.

  • Analysis pinpoints areas most vulnerable to hotter, drier weather causing ground to shrink and drag foundations down

    Millions of homes are at risk from climate-related subsidence, according to an analysis by the British Geological Survey (BGS).

    As hotter, drier summers driven by global heating become more frequent, the ground under houses can shrink and drag down a property’s foundations. The most vulnerable areas include London, Essex, Kent and a tranche of land from Oxford up to the Wash on England’s east coast, according to scientists, who say mitigation measures will be needed.

  • Temperatures above 15C ‘very strange’ say scientists, as snow melts and rain falls on glaciers in usually frozen region

    Temperatures in the Antarctic climbed above 15C this month, shattering the previous winter heat record for the usually frozen region and raising concerns about the speed of climate breakdown.

    The new winter peak temperature was logged by the Argentinian Esperanza base on the Trinity peninsula on 6 June amid a protracted heatwave, when the maximum daily temperature exceeded zero degrees for three consecutive weeks.

  • Critically endangered Tapanuli orangutan population falls after heavy rain and landslides, fuelled by climate crisis, in North Sumatra

    Extreme rainfall and landslides fuelled by the climate crisis killed 7% of the remaining population of the world’s rarest great ape, a study has found, prompting fears for the species’ survival.

    The research suggests 58 out of the remaining 800 critically endangeredTapanuli orangutans (Pongo tapanuliensis) were killed after more than 1,000mm (39in) of rain fell over four days in Indonesia’s North Sumatra province in November 2025. This equates to 11% of the local population and 7% of the entire species.

  • Wolstonbury Hill, West Sussex: The fly orchid looks like no fly I’ve ever seen – its target insect is a wasp. And if you see one being pollinated, you’re one up on Charles Darwin

    Many British orchids are named for their animal or humanoid appearance. List some and you have all the characters for a nursery-rhyme tale of transformation and trickery: lady, frog, man, fly and spider. Today’s protagonist is the fly orchid (Ophrys insectifera), a subtle conjuror of alternate realities and a plant I’m fortunate to encounter yearly on my local South Downs hill. Favouring the dappled interface of chalk grassland and woods, it flowers here from mid-May. It’s hard to spot amid the bugle, wild marjoram, agrimony and dock, but once I have my eye in, I find upwards of 20 plants.

    While they look like no fly I’ve ever seen, the tiny blooms do have an uncannily insectile appearance. This is mostly down to a special petal, the labellum, which is minutely modified for luring in pollinators. Up close, I can see how its edges are curved back just so, a sleight of folding which gives the illusion of volume. An iridescent blue patch at its centre suggests the sheen of folded wings.

  • Conservationists say cherished creatures such as whales, dolphins and seabirds are being killed in large numbers by fishing tackle

    Thousands of Britain’s most charismatic and protected marine wildlife, including whales, porpoises, dolphins, seals and seabirds are being killed as “collateral damage” by fishing vessels every year, according to the first-ever analysis of bycatch data.

    The analysis, by the Wildlife and Countryside Link, a coalition of voluntary conservation groups, reveals the devastating toll bycatch, the accidental capture and killing of non-target species by fishing vessels, is having on marine species.

  • Enfield council in north London took legal action against restaurant chain after outrage over damage to tree

    The UK restaurant chain Toby Carvery has settled a legal dispute over taking a chainsaw to an ancient oak tree without permission, by agreeing to pay to restore a lost orchard.

    The unauthorised partial felling of the 500-year-old oak next to a Toby Carvery car park in Whitewebbs Park, Enfield, north London, in April last year, prompted widespread public outrage and questions in parliament.

  • Crops and flowers rely on them for survival, but wild bees are declining – and crucial nutrients will go missing from our diets as a result

    There are few ways in and out of Nepal’s Jumla district. The Karnali highway, considered one of the world’s most dangerous roads, provides the only land link, splicing through the Himalayas to connect Jumla’s terraced valleys to the rest of the country. As such, the 120,000 people that live there are almost entirely self-sufficient, with most of them eating and selling what they grow.

    It’s a tenuous existence, plagued by food insecurity and malnutrition. In recent years, local beekeepers have bemoaned languishing hives and dwindling honey production, observing that roughly half of their bees seem to have vanished over the past decade. These concerns, however, ignore an even more insidious impact.

  • As the US shuts its doors to most refugees, there’s little hope of a new system to help those forced from home by climate impacts

    Millions of people around the world are having their lives upended by floods, storms and heatwaves worsened by the climate crisis. Those forced to flee their home countries, however, are finding that the door to the US is more firmly shut than ever.

    Neither US nor international law recognizes environmental hazards, such as climate-related displacement, as a valid cause to claim asylum or gain entry through other migration pathways, despite the mounting toll of disasters caused by an overheating planet.

  • US energy secretary Chris Wright featured in seminars to judges when he was a fracking executive

    As cities and states sue big oil for billions in damages over allegations that it covered up the dangers of its products, rightwing organizations are attempting to discredit the wave of litigation. They claim the lawyers behind it are teaming up with an environmentally focused legal education non-profit to bias federal judges against oil companies.

    But it is actually fossil fuel-backed organizations that are attempting to sway the judiciary in their favor, one of those law firms is countering. Evidence of this includes judicial seminars hosted by one such group featuring pro-industry speakers such as the current energy secretary, Chris Wright, in his former occupation as a fracking executive.

  • Pacoima is hemmed in by highways and heavy industry, and its residents are fighting pollution with hyperlocal air quality monitoring

    Jose Luis Salas looks up at the ladder. “Are you ready?” he asks Shance Taylor, an environmental project manager who’s holding a white container, about the size of a shoebox, covered with wires and numbers.

    Taylor nods and climbs up to reach the side of Salas’s tidy house in Pacoima, a neighborhood in Los Angeles’s north-east San Fernando valley. The curious box in their hands is known as Aeroqual sensor – part of a community air-quality monitoring program run by Pacoima Beautiful, a local environmental group.
