Nature Watch, May 2018

Steve Jones, ever on the watch for birds, has some exciting sightings in May.

As Steve reports: Not a great deal to report in May, primarily as two weeks were spent in the UK. That said, the last two weeks of the month have been very interesting with several new sightings which I had not seen before on the island or elsewhere. Also without doubt I had an element of luck, being at the right place and the right time, as two of the new species were just glimpses: I saw the Sand Martin just once among swifts and swallows, and spotted the Lesser Grey Shrike just for a few seconds, but I was still just able to get photographic record shots for confirmation, though not good enough for publication. The Nightjar I recognized by its call, but as I have no hope of getting a daytime picture of one, I am aiming to be more successful with a night-time photo.

If you are an early riser around 04:30-04:45 you may have heard the “dawn chorus”. It's well worth getting up for at this time of year, even if you only do it once! More generally, you have probably noticed this month several species of bird carrying food to their young.

If you are not familiar with House Martins, there is a good opportunity to see them in action at the post office in Vrbanj. They have built a nest right above the door, where the adults fearlesslyfeed their young, so no need for any binoculars or fancy equipment. Closer to home, in my garden, I have a Red Backed Shrike sitting on eggs (presumably). I took the photograph above last week of another Red Backed Shrike, also sitting, about 100 metres from my house.

The male (pictured above) was to be seen quite close by where the female was sitting. There were four young in the nest, which fitted in perfectly until about mid-June. By 17th June, they were so big they were struggling to fit into the nest. Much as I wanted to get a picture of the adults feeding the young, I realised it was pretty well impossible, as they obviously kept away if they saw me anywhere near the nest.

The Black Headed Bunting arrived at pretty much the same time as last year but I have only seen one so far, so they are nothing like as common as the Red Backed or Woodchat Shrikes.

I had a friend visiting for a few days and whilst out one morning we came across three Rose Coloured Starlings for a matter of seconds. I managed to get a record shot but before I could get another picture they were off.

Just minutes after this another first for the island – and that at the pond I visit almost daily. The Squacco Heron, this stayed for three days before moving on.

Without doubt the highlight of the month was a short visit of two Rollers (zlatovrana). The photographs are poor as they were some distance and as it was a first for me. I spent more time looking through the binoculars at the birds than photographing. That said some adequate record shots. These were visible for about three minutes and despite me scouring the area pretty well every day since, no signs.

During the next three months I won’t be going out as frequently. Already things are beginning to quieten down, the Nightingale, which was singing incessantly, has already cut its singing down. I have only heard one Cuckoo in the last five days, but interestingly this year I have heard a female Cuckoo a few times. I still wonder what the host bird may be. My thinking is it might be a Corn Bunting, so if you see an active Corn Bunting, check it out: you never know, it may be feeding a Cuckoo!

The pond I visit is holding its water levels well, there are signs now of it dropping but it is still considerably higher than this time last year. I am also noticing quite a lot of dragonfly activity, several Emperors, Broad Bodied Chasers and an Emerald damselfly (I am awaiting confirmation on which Emerald species).

Finally a shot of everyone’s favourite ……………………….the Bee-Eater, which is one of the strongest draws attracting birding enthusiasts from cooler climates to Hvar.

  • Vast swathes of the country’s trees have been killed off by droughts and infestations, in a trend sweeping across Europe. A shift towards more biodiverse cultivation could offer answers

    Even the intense green of late spring cannot mask the dead trees in the Harz mountains. Standing upright across the gentle peaks in northern Germany, thousands of skeletal trunks mark the remnants of a once great spruce forest.

    Since 2018, the region has been ravaged by a tree-killing bark beetle outbreak, made possible by successive droughts and heatwaves. It has transformed a landscape known for its verdant beauty into one dominated by a sickly grey.

  • Citizen scientists help in University of Bonn study showing river carries up to 4,700 tonnes of ‘macrolitter’ annually

    Thousands of tonnes of litter are pouring into the North Sea via the Rhine every year, poisoning the waters with heavy metals, microplastics and other chemicals, research has found.

    This litter can be detrimental to the environment and human health: tyres, for example, contain zinc and other heavy metals that can be toxic to ecosystems in high concentrations.

  • Abernethy Forest, Cairngorms: Thanks to a local collaborative effort, linnets, bramblings, green and goldfinches are coming to this field in joyful flocks

    It’s -6C and I’m off to what has been a regular haunt recently – a field planted by Speyside Fields for Wildlife. This is a small, community-run charity that works with local farmers, crofters and others to take over “spare” fields and land for wildlife-friendly crops.

    Some sites are planted with annuals such as cornflower, corncockle, marigold and poppy – important sources of pollen, nectar and flowers that used to grow among the grain crops before herbicides became commonplace. Others, such as this one on a hill farm, have been planted with seed crops that benefit birds and other wildlife during autumn and winter.

  • Study of 1,000 products finds wet, raw and meat-rich products have higher climate impact than dry kibble

    Dog food accounts for 1% of the UK’s total greenhouse gas emissions, according to research that found wet, raw and meat-rich products were associated with substantially higher emissions than dry kibble.

    The analysis revealed striking differences in the environmental impact of commercial dog foods, with the highest-impact foods being responsible for up to 65 times more emissions than the lowest-rated options.

  • Shift from ‘big 5’ imports to British fish such as sprats and sardines would help diets and the planet, say researchers

    Supermarkets could help to support British consumers to move away from their reliance on mainly imported seafood – the “big 5” of cod, haddock, tuna, salmon and prawns – to more sustainable, nutritious and locally caught fish such as sardines and anchovies, researchers say.

    A study by the University of East Anglia (UEA), which confirmed previous research showing consumers did not eat the recommended amount of fish in their diet, suggests the UK could be overlooking a major opportunity to improve national health as well as bolstering local economies by embracing its own rich populations of nutritious small fish.

  • Scientists also name an overlooked snowdrop growing in the UK and a fruit that tastes like banana and guava

    A zombie fungus that springs from a trapdoor and a flame-like shrub named after the fire demon in the Studio Ghibli film Howl’s Moving Castle are among the species of plant and fungi named by scientists in 2025.

    A list of 10 “weird and wonderful” new species was compiled by scientists at the Royal Botanic Gardens (RBG), Kew and their international partners, who together named 125 new plants last year. The list also includes an orchid whose flowers look bloodstained and attract sexually aroused flies, and a beautiful snowdrop that had been hiding in plain sight in UK gardens.

  • Outcome of aggression will determine whether rare earths and other resources drive energy transition – or strengthen US military power and oil interests

    The US’s first overt attack on an Amazon nation last weekend is a new phase in its extractivist rivalry with China. The outcome will decide whether the vast mineral wealth of South America is directed towards a 21st-century energy transition or a buildup of military power to defend 20th-century fossil fuel interests.

    Although this onslaught was ostensibly aimed at one corrupt dictatorship in a miserably dysfunctional country, the ramifications are far wider.

  • Cars that emit fumes closer to pavement result in pedestrians experiencing 40% more pollution

    Some vehicles are much more polluting than others and the design of exhaust pipes could affect how much air pollution we breathe when we walk along a busy road, research has found.

    Diesel vehicles still dominate exhaust pollution 10 years after the International Council on Clean Transportation revealed that many diesel cars were highly polluting, emitting far more nitrogen oxides on the road than in official testing.

  • At the Oxford farming conference there were signs the government has much to do to win back farmers’ trust

    Few symbols were more potent than the wooden coffin bearing the inscription “RIP British agriculture, 30th October 2024” that greeted Labour’s environment minister at the annual Oxford farming conference.

    It marked the date of Rachel Reeves’s first budget, when she announced plans to levy inheritance tax on farms. For the chancellor’s cabinet colleague Emma Reynolds, it underlined the anger among Britain’s farmers.

  • Sandbanks can shift position during winter storms, but sonar mapping means charts can now be updated immediately

    Offshore sandbanks are a particular navigation hazard because, unlike rocks and reefs, they have a habit of shifting position during winter storms.

    The Goodwin Sands is a 10-mile (16km) bank off the coast of Deal in Kent, close to the busy shipping lanes of the Dover strait. The sands have claimed about 2,000 vessels over the years. In 1634, two lighthouses were set up on South Foreland for sailors to follow a safe route through.
