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!

  • UK issues rare red heat alert as 68,000 households lose electricity in northern France and Italy puts warnings in place for 16 cities

    Grahame Madge, a Met Office spokesperson, said the agency is forecasting 39C as a headline maximum temperature on Thursday in the UK, most likely for somewhere in London or the south-east.

    “It is possible we could see temperatures higher than the 39C if the final values are at the upper end of our narrow range,” he said, according to the Press Association.

  • Analysis shows cars in Europe have grown longer, taller and wider every year since 2000

    Cars have grown 1.2cm longer, 0.5cm taller and 0.5cm wider each year on average since 2000, analysis of new vehicles sold in Europe has found, in what green groups call “relentless carspreading”.

    The increase in size, which leaves people more likely to be killed in a crash and increases emissions that hurt lungs and heat the planet, has progressed at a roughly steady rate for two and half decades even as family sizes have fallen, the campaign group Transport & Environment (T&E) found.

  • Wildlife photographer Mohammed Almuntasir had no idea what he had found until scientists started to get in touch

    When wildlife photographer Mohammed Almuntasir uploaded 18 seconds of footage to YouTube, he thought little more about the small, pale cat seen digging a hollow in the sand in the remote dunes of south-west Libya.

    The video, however, posted in 2017, turned out to be the first material evidence that the sand cat (Felis margarita), the world’s only felid adapted to true desert conditions, existed in the country.

  • Matriarchal groups in east and west exhibit distinct click patterns, used to form social structures

    From “Howdy” to “G’day”, English – like other languages – is rich in dialects. Now researchers have found sperm whales on different sides of the Mediterranean show similar variations in their vocalisations.

    Sperm whales communicate vocally using sequences of short clicks called codas. However, the rhythmic pattern of these clicks, known as the dialect, can differ between different matriarchal groups.

  • UK regulator has increased its scrutiny of fashion retailers over potentially misleading environmental statements

    Ads for Calvin Klein, Adidas and Uniqlo promoting “recycled” clothing and shoes have been banned by the UK watchdog after the advertisers were unable to prove their green claims.

    Each of the fashion companies ran paid-for Google ads, with Adidas promoting “recycled running shoes”, Calvin Klein “recycled” tops for women, and Uniqlo advertised fleece coats and jackets made from “recycled materials”.

    Weakening the UK’s net zero policy would disrupt business and damage the economy, the UK’s chief climate adviser has warned.

    Nigel Topping, chair of the Climate Change Committee (CCC), said: “The U-turns are really damaging to inward investor confidence. If we really want to grow the economy, then investing and getting good at building stuff is essential.”

  • Photographer Shane Hynan explores the tension between the central role peat bogs play in Irish life and their wider environmental impact

    “You can read Ireland’s history in the boglands. They hold millennia in their layers,” says photographer Shane Hynan of his project, Beofhód (meaningBeneath in English).

    The boglands, known as portachs in Irish, cover roughly 1.2m to 1.5m hectares or about 14% to 17% of the country’s total land area. The raised bogs of the Irish Midlands are made of peat that forms at a rate of 1mm a year (0.04in) in low-lying, poorly drained basins or former lakes. As the historical geographer Kevin Whelan observes in the Atlas of the Irish Rural Landscape, “the bog has been etched as deeply into the human as into the physical record in Ireland – to an extent unrivalled elsewhere.”

  • Researchers assessed likelihood gas was produced during creation of Alps, Pyrenees and Baetic mountains

    Hydrogen gas is anticipated to play a central role in phasing out fossil fuels, particularly in industries that are proving more challenging to decarbonise, such as chemical production, shipping and steelmaking. But producing hydrogen synthetically is energy intensive and costly. In order for the hydrogen economy to take off, we need to find reliable natural sources of this gas. Could it be hidden in the mountains?

    Researchers used plate tectonic simulations to investigate the Pyrenees, Alps and Baetic mountain ranges to assess if their mountain-building processes were likely to have resulted in hydrogen being produced and stored. Their findings, published in the Journal of Geophysical Research: Solid Earth, showed that the Alps and Pyrenees could be strong natural hydrogen exploration sites.

  • As hot weather becomes more common, companies and homeowners are coming up with innovative ways to keep properties cool

    When graphic designer Marc Alabaster had a new set of glass doors installed at his West Sussex home eight years ago, he soon realised how they magnified the heat of the afternoon sun.

    “The kitchen was 40-plus degrees,” he said. Then he went on holiday to Spain and saw an apartment building wrapped in louvre-like rows of angled fins or blades that shaded the external walls against the sun.

  • The cost of the traditional takeaway has doubled since 2019, and more outlets are trying to tempt customers with cheaper options such as coley, pollack and hake

    In late April, visitors to Harbour Lights in Falmouth, Cornwall, may have raised an eyebrow. The fish and chip shop was in the midst of a “cod-free week”, its owners having removed cod from its menu entirely.

    It was the second time owner Pete Fraser had undertaken the experiment, 15 years after the first. He also removed cod from his shops in Penzance and Helston, replacing it with coley, pollack, hake and hoki. The result was very different. “Some of the feedback we had, which certainly wasn’t what we got when we ran it years ago, is ‘Can you repeat this?’ Before, it was like, ‘Have you guys lost your head’?”
