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!

  • Food produce and other waste has been littering Sussex coastline as capsized shipping containers wash ashore

    Coral Evans was walking along the beach in Brighton on Tuesday evening when she came across an unfamiliar sight.

    “Hundreds of dust masks had washed up, along with single-use plastic gloves and cans of dried milk,” she said. “It was odd to see in winter – because nothing surprises us in summertime with the amount of people on the beach.”

  • Tony Cholerton created Robovacc to inoculate a timid tiger at London zoo – but says it could administer jabs to badgers

    It began with the tiger who wouldn’t come to tea. Cinta was so shy that she refused to feed when keepers at London zoo were around, and staff wondered how they would ever administer the young animal’s vaccinations without traumatising her.

    So Tony Cholerton, a zookeeper who had been a motorcycle engineer for many years, invented Robovacc – a machine to quickly administer vital jabs without the presence of people.

  • The cost of producing milk is higher than that being paid by milk processors, leaving farmers operating at a loss

    “Every morning that I roll out of bed at 4.40am, I know I’m losing £1,800 that day, just by getting up.” This is the stark daily reality for Paul Tompkins, as he and his fellow dairy farmers struggle in the face of plummeting milk prices.

    Tompkins, who is the third generation to run his family’s 234-hectare (600-acre) farm in the Vale of York, can produce milk for about 40p a litre from his 500-strong herd of black and white Holstein cows. However, he is being paid only 29p a litre by his milk processor, leaving him operating at a loss, despite trying to run his business as efficiently as possible.

  • Virunga park ranger says babies are well cared for by mother Mafuko but high infant mortality makes first weeks critical

    It was noon by the time Jacques Katutu first saw the newborn mountain gorillas. Cradled in the arms of their mother, Mafuko, the tiny twins clung to her body for warmth in the forest clearing in Virunga national park, in eastern Democratic Republic of the Congo (DRC).

    Katutu, head of gorilla monitoring in Virunga, has seen dozens of newborns in his 15 years as a ranger. But, he tells the Guardian, even he was touched by the sight of the fragile infant males, who face serious obstacles if they are to become silverbacks one day.

  • As international treaty comes into force, bill to make it law in Britain is moving at ‘glacial pace’ through parliament

    The UK risks being shut out of a historic oceans summit because parliament has failed to ratify the UN’s high seas treaty, environmental charities and campaigners have warned.

    The high seas treaty, formally known as the Agreement on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction, comes into force on Saturday, after two decades of talks.

  • Cranbrook, Kent: I have a stretch of leggy hawthorn that needs attention, so I head out into the cold with my axe and billhook

    Wire netting is everywhere in the Kent Weald – barbed boundaries to ancient pastures where sheep and cattle still idly graze. But what did farmers do for the hundreds of years before stock fencing was invented?

    Hedges, so rooted in what we wistfully consider to be our natural landscape, are in fact human-made features, planted almost solely for the purpose of enclosure. Unmanaged hedges are not a permanent solution, though: young trees mature, trunks become bare, and animal‑sized holes appear, rendering them useless. To remedy this, the practice of hedge laying was developed; unlike bricklaying, it is an act of maintenance rather than creation.

  • Todolí foundation produces varieties from Buddha’s hands to sudachi and hopes to help citrus survive climate change

    It was on a trip with a friend to the east coast of Spain that the chef Matthew Slotover came across the “Garden of Eden”, an organic farm growing citrus varieties he had never heard of. The Todolí Citrus Foundation is a nonprofit venture and the largest private collection of citrus in the world with more than 500 varieties, and its owners think the rare fruit could hold the genetic secrets to growing citrus groves that can deal with climate change.

    The farm yields far more interesting fruit than oranges and lemons for Slotover’s menu, including kumquat, finger lime, sudachi and bergamot.

  • Pioneering scheme hopes species that thrived for thousands of years in Irish waters can do so again

    The dinghy slowed to a stop at a long line of black bobbing baskets and David Lawlor reached out to inspect the first one.

    Inside lay 60 oysters, all with their shells closed, shielding the life within. “They look great,” beamed Lawlor. So did their neighbours in the next basket and the ones after that, all down the line of 300 baskets, totalling 18,000 oysters.

  • Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences

    On one side of Dr Ben Galton-Fenzi’s view across the vast Totten ice shelf, the sun sat low on the Antarctic horizon. On the other, a full moon.

    The ice shelf is “flat and white”, says Galton-Fenzi. “If there’s cloud around, you lose the horizon.”

  • The cattlewoman is stranded alone, rationing her supplies and worried about her health. Meanwhile the mine sits mothballed

    Cattlewoman Trish Goodwin should be celebrating.

    Last Friday, her parched property off the Capricorn Highway near the tiny town of Bluff in the central highlands of Queensland received “very good soaking rain” – nearly 200mm would fall in a few days.
