Birdwatch March-April 2018

Steve reports from Dol on the unsettled spring weather, and the welcome bird arrivals on Hvar.

March and April have continued to bring the species in and as at April 24th I have seen 77 species with possibly two or three unidentified. March continued to be another month with a very heavy rainfall. My “marker stick” (an indicator as to pond levels in 2017) has completely disappeared and is still not visible near the end of April.

I am thinking the birds have been arriving slightly earlier than last year, up to two weeks in many cases. As my data is limited, does it mean they were late coming back in 2017? Without several years' data you can’t get an accurate picture of their movement, but at least you do have a general idea on when you would expect to see certain species.

By March 10th, things were already starting to move on. The Great Tits that were the most numerous feeders had gone, I could hear the odd one singing here and there but by and large the bulk had disappeared. Blue Tits and Chaffinches were continuing to feed, but would stop in the next 10 days or so. Blackbird numbers dropped dramatically so I was wondering if a fair proportion have gone off to breed elsewhere. The Lapwings which had been pretty numerous in comparison to last year arrived on February 22nd this year, as I recall, but now by March 10th I had not seen not seen one in three days. My first sighting of a Lapwing on the island was on February 14th 2017.

The arrival of the Scops Owl and Nightingale was pretty much to the day as it was last year. I have also heard a Chiff Chaff in three consecutive years at pretty much the same place and time, and I am convinced it pauses briefly here and then moves straight on.

In early March there were several species of duck on the pond, Teal, Wigeon and a new one for me, Garganey. They proved very difficult to get a picture of despite numerous attempts, the slightest movement and they were off. Under normal circumstances they may well have returned quite soon, but because all of the surrounding fields were water-logged these and several other species were flying further away. I found evidence of this on numerous occasions with the Lapwings and Ruffs.

Another highlight for me was the touchdown of the Common Crane. In 2016 I noted a big flock passing over in the Autumn. Here at the beginning of March I saw twelve just fly over. March 2nd however three birds landed on the airfield. These three were seen at various locations for a further eight days or so.

March was also clearly the month for watching birds of prey. Sparrowhawks and Kestrels were seen almost daily.

Also there have been several Marsh and Hen Harriers around. Although I took many pictures I am afraid they are more as a record of the species than for publication. I did capture a Kestrel, Sparrowhawk and Buzzard, our most common birds of prey on the island.

March 24th was the end of a fantastic week, when I saw Marsh Harriers daily three days running. I think they were only passing through. I didn't manage any decent pictures. But I did get a fantastic picture of a Golden Plover that morning, in its transition phase, changing from winter to summer plumage. This brought the number of species seen so far in 2018 to about 58.

April continued with the steady trickle of new arrivals. I noticed a lot more Sub-Alpine Warblers this year than last: perhaps they enjoyed a successful breeding season in 2017. I would suggest they are probably the most numerous summer residents along with the Nightingales which are singing at all hours of the day and night. I keep trying, but I have still yet to photograph one of the latter.

From about the 14th April, the Buzzard seemed to have moved, appearing less and less frequerntly towards the end of the month, though you still might see the odd one.

I have been trying for a long time to get a picture of a cuckoo, with difficulty. This one is not great, but at least you can see what it is.

I think without any doubt the highlight for me so far this year was ( whilst searching for a Cuckoo ) finding the Eagle Owl in daylight, probably just before 07:00 hrs on 17th April. I had a good view of it for about a minute, I managed three poor photographs but for the many people that hear these birds now you know what they look like.

Between 18th and 19th April there was a big movement of birds coming in, with several Whinchats and Whitethroats appearing on the morning on the 19th, and my first Alpine Swift of the year, Last year's first sighting of the Alpine Swift was on March 30th. On April 21st the Bee-Eaters arrived in my area, as did Turtle Doves, and there was a Purple Heron at or near the pond. The Golden Oriole arrived but it was moving about and only calling periodically. Golden Orioles are very nervous of movement of any kind, so they fly to nearby trees at the slightest disturbance when I spot them near the pond. One needs to use the binoculars to get a good view of them.

Towards the end of April, the Blackbirds which had settled were often to be seen carrying food, a sure sign suggesting they now had young. The warm weather at the end of the month ensured that the early morning chorus of birdsong has been particularly joyful!

  • A former UK government scientific adviser warned amid the ‘shattering’ heat that worse is still to come

    Met Office has just offered an update on temperatures across the UK, with several stations already reporting temperatures above 30C – and it’s not even 11am.

    It’s 30.4C in Wych Cross, 30.3C in Charlwood, 30.2C at Kenly Airfield.

  • From spiders tuning their silken listening tools, to the beetle’s heady perfume, hundreds of conversations are happening in languages we don’t understand

    All around us, every day, hundreds of conversations are taking place in languages we don’t understand, or even, in most cases, notice. Birdsong is one you would probably recognise, and you may have heard of honeybee “waggle dances”. But what about the spider tuning their web to listen for prey, or a waft of arousing perfumes emitted by a passing beetle? At any moment you may be walking right through a whole critical dialogue – and have absolutely no idea.

    To delve into the world of invertebrate communication about food gathering, coordinating nest building, defending a territory, attracting a mate, and babycare is to realise just how smart and sophisticated they are. Spiders, for example, can “hear” vibrations on the silken strands of their web using sensors on their legs. With their legs and body weight, the spiders will adjust the silk strings, as we would a guitar string, to change its pitch, pulling, loosening or reconnecting strands to adjust how it sounds. In fine-tuning the silk they can know just who is walking on it – a possible mate to woo, a fly for feasting on or maybe a larger bug on the lookout for prey.

  • Bat experts were shocked at how fast white-nose syndrome had spread to Canada’s northernmost colonies from the US. Now, the race is on to find a cure before species disappear

    Crawling through a narrow passage in a cave beneath a boreal forest near Fort Smith in Canada’s Northwest Territories in May, two biologists spotted a lifeless bat on a limestone ledge, its body covered in a spindly white fungus.

    When they shone their headlamps to get a closer look, they saw another bat with the fungus on its forearms. “It hissed at us and crawled back into a crack,” Jesika Reimer says.

  • PM to look at imposing restriction on devices in public spaces, though campaigners fear it does not go far enough

    The government will look at banning disposable barbecues as wildfires continue to rage across the UK, Andy Burnham has said.

    Disposable barbecues have been the cause of a number of serious fires over the last few years, but campaigners were critical of the prime minister’s failure to link those fires more broadly to the climate crisis.

  • Rejecting North Sea drilling licences and protecting nature are just some measures Andy Burnham must implement to ready country

    From record-smashing temperatures, wildfires, hosepipe bans and thousands of premature deaths, the climate crisis has left its mark across the summer of 2026.

    Tackling the root cause – the burning of fossil fuels – and ending the crisis will take years. So will fixing the UK government’s calamitous failure to protect lives and livelihoods against the long-predicted affects of global heating.

  • The gigantic aquatic acrobats are exciting Brazil’s tourists as numbers recover from whaling. But some marine biologists question how booming tourism and conservation can coexist

    The anticipation is palpable onboard the Boaventura II as the yacht sets off from Rio de Janeiro at sunrise. Once beyond the Cagarras Islands, rocky outcrops just three miles off Ipanema beach, the group gathers at the bow and starts scanning the horizon.

    They do not have to wait long. “Eleven o’clock!” someone calls out, as a pod of bottlenose dolphins appears, playfully diving in and out of the water. Then, two spouts of vapour hanging in the air signal the reason for the outing: a pair of humpback whales. The majestic mammals surface to breathe with an unhurried chuff, before revealing the underside of their fluke as they dive back underwater.

  • It might seem an unlikely way to stop overheating, but many owners have found the tech a lifeline in hot weather

    “If it is 35C outdoors, I can get the temperature down to 21C,” says Andrew Ingram of the sanctuary that his living room has provided this summer.

    “On the nights I’ve slept in there, you have to put your thick pyjamas on,” jokes Ingram, who lives in Maidenhead, Berkshire, with his wife, Sue.

  • Two years after southern Brazil’s worst climate disaster ravaged the city, and with poor areas still recovering, many fear official neglect has left them exposed once again

    In the backstreets of Porto Alegre, a state capital in southern Brazil, you can still see signs of the devastating flood that swept through the city two years ago: scattered debris, waterlogged homes and destroyed businesses.

    In May 2024, flooding killed 183 people in the state of Rio Grande do Sul and displaced more than 600,000. The neighbourhood of Sarandi was one of the hardest-hit parts of Porto Alegre, with water levels reaching up to 5 metres above normal, completely submerging many of its streets.

  • Dress like a zebra, wash your feet, keep off the beer: insect experts explain what works and what doesn’t – and why some of us get bitten more than others

    It’s a good time to be a mosquito or other blood-sucking insect. In the UK and beyond, they are enjoying the summer heat, and there are lots of humans outdoors, some wearing very little, like an all-you-can-eat walking buffet. Some of the humans are drinking beer, which apparently makes them even more irresistible to mosquitoes. Many of us are warm and sweaty, which is all the better for the blood-suckers seeking us out.

    Insect populations are changing because of the warming climate and there are organisations keeping an eye on invasive species, especially mosquitoes, which can be vectors for diseases such as dengue and malaria (globally, more than 600,000 people a year die from malaria). The UK “will have a threat from mosquito-borne diseases as time goes on,” says James Logan, professor of medical entomology at the London School of Hygiene and Tropical Medicine, and CEO of Dot, an “odour intelligence” company. “The biggest threats are arboviruses [viruses transmitted by arthropods, especially insects and ticks], such as dengue. We have mosquitoes throughout [mainland] Europe now that can transmit dengue. We also know that we do get those mosquitoes coming across to the UK, but they don’t seem to be breeding here successfully and surviving over the winter.” But, he warns, with milder winters and warmer summers, it is only a matter of time.

  • Söderåsen national park is one of Europe’s largest protected broadleaf woods, offering wild swimming, spectacular hiking trails and an inspiring story of regeneration

    From the bus window, the ridge looks like a giant slumbering beast stretched deep green across the flat farmland. “It feels alive,” I say to the woman beside me. “Yes,” she answers. “It is where you would run for safety, don’t you think?”

    I am in southern Sweden to explore Söderåsen national park, established in 2001 to protect more than 1,600 hectares (4,000 acres) of the larger Söderåsen ridgeline. Shaped over millennia by immense geological collisions, fractures, volcanic eruptions and ice ages, today it is one of northern Europe’s largest continuous protected broadleaf forests, and only 90 minutes by car from Copenhagen or, in my case, two hours by public transport.
