Steve reports from Dol - he feels there should be more to see!

Another disappointing month in terms of species numbers. The birds continue to flock to the feeder in waves. Nothing for an hour and then all seem to descend and up to 20 of mainly the three species, Blue Tit, Great Tit and Chaffinch feeding from the ground.

3rd Feb: Sparrowhawk flew over the garden……….. an obvious sign to look up when the birds around disappear and go quiet.

6th Feb: On the Vrbanj road a flock of 25-30 Hooded Crows. Great Tits were calling far more frequently now.

12th Feb: a huge flock of Chaffinch coming back from Stari Grad towards Dol, I should think in excess of 100. As I was driving I suspect there could have been other species amongst them but as is often the case no suitable place to pull in.

13th Feb: Buzzard, Sparrowhawk and first time of seeing Black Redstart this year (or actual confirmation)

14th Feb: Weather really quite mild and saw a female Egyptian Grasshopper and several butterflies on the wing. Red Admiral is pretty well all year round but saw some “whites” in flight.

About 19:00 noticed several frogs on the road coming back to Dol, can only presume weather conditions had brought this on, not noticed any since.

17th Feb: Blackbird singing (see video below or click here)

19th Feb: Blackcap singing & saw my first Brimstone butterfly although my friend had seen one several days before but was unsure of the species.

20th Feb: Male Black Redstart in the garden and around some nearby ruins.

21st Feb: My first Painted Lady (Butterfly)

22nd Feb: Cirl Bunting on the road near Stari Grad airfield.

25th Feb: Opposite Konzum in a tree in Jelsa  - 25-30 birds some singing. Went back to the car to fetch binoculars predominantly Chaffinch which I could identify but amongst them were some Goldfinch and the thing that drew my attention initially were some Serin singing. Before I managed to get a picture they disappeared.

29th Feb: was in Split and saw my first Black Headed Gull in “summer plumage” or at least I am assuming it was a Black Headed Gull and nothing else but no binoculars to confirm. For those of you who don’t know, these birds lose the Black Head in the Winter.

As the weather has been relatively mild I had been expecting more migrant birds coming in towards the latter days of February but nothing that I have seen. I have heard reports of the odd Swallow arriving in February but perhaps the weather has held them back.

In the UK I generally accept the arrival of Spring as the Chiff Chaff return, on or about March 10th. So let’s hope in March there is more to report.

Footnote from Steve March 23rd 2016:

Just back from the UK, I heard my first Chiff Chaff here in Dol today, I usually associate that with the first of the migrants in the UK (heard a couple last week over there, would have expected them earlier here but clearly not). Now I am back I will concentrate my efforts in the next two months. I have heard that Swallows have been seen in Dol last week.

it is interesting that one night at a hotel in Dover I counted twice as many species in 10 minutes while walking to get a paper than I have seen here all Winter.

I keep wondering am I missing something or perhaps not going to the right locations, however I will carry on.

Comment from Vivian Grisogono of Eco Hvar:

I am (sadly) of the opinion that all the herbicide spraying is responsible for the lack of birds, not to mention the definite dramatic decline in bats - almost to nothing last year. Ground feeders have no chance when the earth is dowsed in poison, not to mention what happens to the insects and micro-organisms which healthy earth depends on?

  • Exclusive: Beijing, Delhi, Los Angeles and Rio de Janeiro among worst affected, with demand close to exceeding supply

    Half the world’s 100 largest cities are experiencing high levels of water stress, with 38 of these sitting in regions of “extremely high water stress”, new analysis and mapping has shown.

    Water stress means that water withdrawals for public water supply and industry are close to exceeding available supplies, often caused by poor management of water resources exacerbated by climate breakdown.

  • The removal of sulphur from shipping fuels caused ‘a lot of extra sunlight’ to get through atmosphere and hit reef in 2022

    Steps to clean up the shipping industry by removing sulphur from fuels intensified a major coral bleaching event on the Great Barrier Reef by allowing more of the sun’s energy to hit the oceanic wonder, according to a new study.

    Sulphur pollution can cause respiratory problems for humans and cause acid rain, but it also has a shading effect and can make clouds brighter, providing more shade to areas underneath.

  • Researchers say event described as ‘major tipping point’ for clean energy in era of destabilised politics

    Wind and solar overtook fossil fuels in the European Union’s power generation last year, a report has found, in a “major tipping point” for clean energy.

    Turbines spinning in the wind and photovoltaic panels lit up by the sun generated 30% of the EU’s electricity in 2025, according to an annual review. Power plants burning coal, oil and gas generated 29%.

  • Described by one researcher as looking ‘already dead’, the enigmatic creatures are one of the least understood species on the planet

    It looks more like a worn sock than a fearsome predator. It moves slower than an escalator. By most accounts, it is a clumsy and near-sightless relic drifting in the twilight waters of the Arctic, lazily searching for food scraps.

    The Greenland shark, an animal one researcher (lovingly) said, “looks like it’s already dead”, is also one of the least understood, biologically enigmatic species on the planet.

  • Manual for building design aims to encourage low-carbon construction as alternative to steel and concrete

    An airport made of bamboo? A tower reaching 20 metres high? For many years, bamboo has been mostly known as the favourite food of giant pandas, but a group of engineers say it’s time we took it seriously as a building material, too.

    This week the Institution of Structural Engineers called for architects to be “bamboo-ready” as they published a manual for designing permanent buildings made of the material, in an effort to encourage low-carbon construction and position bamboo as a proper alternative to steel and concrete.

  • It’s not just Tunbridge Wells – a country famous around the world for its rain is in danger of self-imposed drought

    You get up and go to the loo, only to find the flush doesn’t work. You try the shower, except nothing comes out. You want a glass of water, but on turning the tap there is not a drop. Your day stumbles on, stripped of its essentials: no washing hands, no cleaning up the baby, neither tea nor coffee, no easy way to do the dishes or the laundry. Dirt accumulates; tempers fray.

    The water company texts: we are so sorry; colleagues are working to restore connection; everything should soon be normal. You want to believe them, but the more it’s repeated, the more it becomes a kind of hold music. There’s no supply the next day, and the day after, and the day after that. Each morning brings with it the same chest-tightening question: what will happen today? Buckets and bottles don’t stop you feeling grubby and smelly, or from noticing the taint on your family and friends and neighbours. You’re not quite the people you thought you were and nothing feels normal.

  • Experts say big flaw is the lack of mandatory requirements, meaning developers could ignore the guidance

    Housing where shops, schools, public transport and possibly pubs are close by, with green spaces and access to nature, and where heritage is preserved, should be the norm for all new developments, according to guidelines set out by the government.

    King’s Cross in London, for example, where industrial buildings have been converted into shops, restaurants and public spaces, and where schools and care homes mingle with social and private housing near to a cleaned-up canal and nature reserve, could become the model, according to the new vision.

  • Our passion for these cute-looking salamanders means they are everywhere – except in the wild, where the species is under increasing threat

    Axolotls are the new llamas. Which were, of course, the new unicorns. Which triggered a moment for narwhals. If you are an unusual-looking animal, this is your time. Even humans who have never seen an axolotl – a type of salamander – in the smooth and slimy flesh will have met a cartoon or cuddly one. Mexican axolotls have the kind of look that is made for commercial reproduction. The most popular domestic species is pink. Some glow in the dark – and their smile is bigger than Walter’s in the Muppets.

    At Argos or Kmart, you can buy axolotls as cuddly toys, featured on socks, hoodies and bedding, or moulded into nightlights. You can crochet an axolotl, stick a rubber one on the end of your pencil or wear them on your underpants. The Economist says they’re a “global megastar”. More than 1,000 axolotl-themed products are listed on Walmart’s website. They grace US Girl Scouts patches, McDonald’s Happy Meals, and the 50-peso bill, a design so popular that, last year, the Bank of Mexico reported that 12.9 million people were hoarding the notes.

  • A study of Arabidopsis thalianaplants found that plants growing together activated genes to protect themselves, while isolated plants did not

    Plants growing close to each other can warn each other about stresses in their lives.

    Thale cress (Arabidopsis thaliana) plants were grown on their own or crowded so close together they were touching each other. When all the plants were then stressed with intense light, the isolated plants suffered severe damage, but the crowds of plants were able to cope with the stress. In fact, it just took an hour for the crowded plants to switch on more than 2,000 of their genes that were involved in protecting against a host of different stresses; in contrast, the isolated plants showed little sign of any extra gene activity.

  • As Labour shakes up regulation, suppliers are finally investing – but face problems such as contractor shortages and inflation

    When a sluice gate failed 24 metres below the water’s surface at Thames Water’s Queen Mother reservoir near London’s Heathrow airport, there were no easy fixes available. Emptying 37m cubic metres (1,307m cu ft) of water was not an option, meaning that helmeted divers were limited to 98-minute stints in the high-pressure environment.

    The risky project required a team on a floating platform with a crane to cut out the broken equipment with thermal lances, bolt a plate on to the reservoir wall, and install the new equipment. It took more than a year until last October to complete, according to Glenfield Invicta, the contractor that carried out the work for Thames Water.
