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!

  • Global report provides an alternative to climate breakdown, political extremism and economic tensions

    ‘Happiness is not just about GDP’: ambitious plan or utopia?

    Humanity can raise living standards, reduce inequality and keep global heating within a 2C rise, according to a sweeping vision for planetary survival.

    The report by the World Inequality Lab (WIL) aims to be the most comprehensive attempt yet to navigate the polycrisis that is pushing the world toward climate breakdown, political extremism and ever greater economic and social tension.

  • Smartphone data shows how we seek refuge in extreme heat, and why social inequalities leave some vulnerable

    Heatwaves are now an increasingly expected part of summer for many. But how people stay cool varies from place to place. A new study uses mobile phone location data to track where people go when the mercury climbs, and assesses how we need to adapt to live better with the inevitable heatwaves to come.

    During the summer of 2025, a 10-day extreme period of heat across Europe led to 2,300 deaths. Globally, governments are implementing heat action plans, but social inequalities mean some people are more vulnerable to heat than others. Researchers used mobile phone location data across seven countries – Brazil, China, France, India, Nigeria, Turkey and the US – to assess how people stayed cool during heatwaves in 2022 and 2023.

  • Electric shock is one of the biggest causes of death among wildlife in the country but a court ruling is a first step to making power lines safe

    Peque, a small black howler monkey, scratches her head as she sits on a thick wooden branch in a wired enclosure with seven other orphaned baby howler monkeys at a rescue centre in Nosara, on Costa Rica’s Pacific coast.

    Last year, Peque was one of more than 100 animals to arrive at International Animal Rescue Costa Rica (IARCR) as a result of electrocution on power lines, which primates such as monkeys frequently mistake for trees and vines.

  • Campaigners say builders’ demolition of nest site highlights weak protection of wildlife from development

    A building that was a noted nesting site for swifts, among the UK’s most at-risk birds, has been demolished during the nesting season, highlighting significant weaknesses in the protection of wildlife from development, campaigners say.

    Contractors for the housebuilder Hill Group carried out the demolition of Regent House near Dorking station in Surrey over the last few weeks, during the nesting season which runs from 1 March to 31 August.

  • Bridport, Dorset: The female in my garden has been a glittering presence of late, but soon she will return to the river to breed

    The beautiful demoiselle (Calopteryx virgo) is aptly named. This loveliest of damselflies is on the wing now across south-west England and Wales, fluttering like a falling scrap of metallic paper among the vegetation.

    One of only two species of damselfly with coloured wings, the males have blue bodies and dark-sheened wings while females are green with contrasting tan wings. But such a plain description doesn’t begin to capture their true appearance.

  • Bank of England says updated imagery will celebrate native wildlife while bolstering anti-counterfeit features

    Puffins, dolphins and bumblebees are among the wildlife that could feature on new banknotes in the UK as the Bank of England announces its shortlist.

    There has been controversy over the decision, with figures including Nigel Farage criticising the Bank for, he claimed, wanting to replace Winston Churchill with a beaver. The Conservative leader, Kemi Badenoch, said it was “a silly thing to do”, and Reform UK’s Farage called it “absolutely crackers”. In the end, no beaver appeared on the shortlist. Mammal options include bottlenose dolphins and red foxes.

  • Governments urged to act to prevent potentially disastrous impacts on human resistance to medicines

    The use of antibiotics on livestock will rise by nearly a third in the next 15 years without government intervention, according to new global estimates, with potentially disastrous impacts on human resistance to essential medicines.

    Animal husbandry accounts for close to three-quarters of global use of antimicrobial medications and in many countries their use is poorly monitored. Some herds are routinely dosed and in many countries antimicrobials are used to increase the growth of animals bred for meat.

  • ​The first heatwaves of the season reveal how ​ill-prepared governments across the continent are to protect people from increasingly dangerous temperatures

    Meteorological summer has begun, ushered in with scorching heat that struck before spring was up. Although western Europe is nowmostly free from last week’s heat dome – which shattered temperature records for May in the UK and Ireland – it is already bracing for yet another sweltering summer. Oppressive days, restless nights and furious fires are brewing. On Tuesday, the World Meteorological Organisation warned us all to prepare for the imminent return of the warming weather pattern El Niño.

    Scientists have not worked out how many people died during thislatest bout of hot weather, but one environmental epidemiologist’s early modelling pegged it at 250 extra deaths in the UK alone on the weekend before temperatures peaked. The full death toll is likely to be particularly high because the heat struck before people had properly adjusted their behaviour to stay safe in the heat.

  • Understanding whale sounds could help prevent strikes from ships and even aid in search for extraterrestrial life

    If you stand on certain shorelines and listen carefully you might just hear deep rumbling noises. Sharp-eared fishers, lighthouse keepers and sea kayakers have been haunted by these late-night sounds for centuries and now, for the first time, scientists have recorded these thrums and pinpointed them to humpback whales, proving that whales have a far larger vocabulary than previously thought.

    Fred Sharpe from the Alaska Whale Foundation and his colleagues set up land-based microphones to tune in to the mysterious ocean noises. Tip-offs from Alaskan coastal communities helped to narrow down the best recording locations. Along with the previously documented trumpets, blows and shrieks that humpback whales make, the researchers recorded very low frequency rumbles, a bit like distant thunder, and new sounds including pizzle, howl and hooting noises. The night thrums travelled through the air and could be heard up to 6 miles (10km) away.

  • Physical and psychological impacts of a tap water parasite outbreak continue to be felt in south Devon

    Most of the tourists milling around the busy fishing harbour or visiting Agatha Christie’s riverside holiday retreat have probably forgotten what South West Water euphemistically calls the “Brixham incident”.

    But for residents at the centre of the “incident” – a parasite outbreak that caused perhaps hundreds of people in south Devon to fall ill after they drank contaminated water – the physical and psychological impacts are still keenly felt.
