Reports from Dol, many thanks Steve!

My bird watching sadly has been rather limited this year, the intention is to make more detailed notes in 2016 - or just wishful thinking.

I had a friend came over in September for a week and I think he listed 29 species in that time excluding Bee-eaters which had gone by then. Saw my last Swift on 27th October, two months later than we would have in the UK. My friend specialises in Moths and set up a couple of traps in my garden for a week. He was delighted with the quantity and species. Probably about 200 different species which I have pictures of - unfortunately I am not knowledgeable enough to identify any.

I erected a bird table about three months ago and was rather disappointed by the lack of interest in it. However in the last three weeks it has been a source of food for about 10 Blue Tits / some Great Tits and a Robin.  There clearly is enough natural food for several other species.

Blackcaps are feeding on pomegranate tree nearby, the occasional Wren pops into the garden and numerous Chaffinch feed off the ground in a neighbours field. Sova Usara calls regularly but seeing it is a little more difficult although some super views in August on an old ruin next door. Saw a male and female Cirl Bunting on some Blackberry bushes nearby on Monday/Tuesday this week.

Last week was seeing Black Redstart/Redstart ( I thought Redstart but two friends think Black Redstart so we will go with them - it is a female and they are both pretty similar). It sort of makes sense as I was positive I saw a male on roof briefly the other week.

I had two or three trips to the airfield in the summer/late summer and found a few species there. Managed to get a reasonable picture of a young Golden Plover which was a surprise to me. Having seen them in flocks on Dartmoor in the Winter, I have never seen one solitary bird. I also saw Yellow Wagtails. There was a solitary Heron at the small pond near the airport, but I was expecting more, as it is the only source of water I know of. Blue Rock Thrush nested nearby which solved a problem I had had for a while, I was familiar with the call over several years, but hadn't managed to tie it up to the bird until now. Also Nightjars were heard most evenings.

Olive picking yielded an unexpected treasure

A great find whilst picking Olives: this caterpillar, which I estimate to be about 10cm long X 1cm wide, later becomes the deathshead hawkmoth ( I didn't know that, but am reliably informed - a fantastic sight and so well camouflaged).

I will endeavour to detail more next year - you mentioned hearing a Cuckoo on April 24th, which is interesting, as that is around the same time that they reach Dartmoor. There has been an interesting project in the UK for the past 3 years now, involving radio tagging cuckoos to track their progress and whereabouts. Really fascinating. I am wondering whether or not they actually breed here, or just pass through. And what is their host bird if they breed here?

I have been a bit disappointed by the lack of birds in the winter, I was expecting far more, but pleased my bird table is attracting some of the more common speicies. Did see four Buzzards conveniently perched on four pylons on my way into Stari Grad this morning.

I went off bird watching early Xmas morning  - over to the airfield and the pond nearby.

Saw the usual Heron and 2 Pied Wagtail.

Saw several flocks of Chaffinch in trees (overnight roosts perhaps) between there and Stari Grad. Up to 60 or so on one tree and a couple of instances of similar driving back to Dol.

Another pair of Cirl Buntings down near the electricity sub-station at Stari Grad. Several Buzzards but all too distant to get decent pictures. I have noticed Great Tits in the last two days are actually calling now.

  • Guardian and Mongabay reveal approaches to officials and MPs on behalf of Vantara zoo ahead of UK-chaired Cites meeting on endangered animal imports

    British government ministers were told not to engage formally with Vantara, the controversial mega-zoo run by the Indian billionaire Anant Ambani, after lobbying efforts by the private animal sanctuary in the run-up to a UK-chaired meeting on the trade in endangered species, according to documents.

    This week, the UK heads a 32-country committee meeting in Geneva of Cites, the United Nations body that regulates trade in endangered species. The meeting will examine how India has responded to compliance concerns about imports of endangered animals.

  • Cop30 host sets out steps to break link with coal, oil and gas as it aims to move focus from negotiating to implementing

    All countries can start to break their dependence on fossil fuels now without needing to wait for new technologies or economic changes, Brazil’s government has said ahead of a global climate summit.

    Brazil, the host of last year’s UN climate conference, set out the world’s first global “roadmap” for phasing out fossil fuels on Tuesday, showing that countries could boost their economies and pull people out of poverty while breaking the link with coal, oil and gas.

  • Garden Climate Assessment Tool will allow users to predict a plant’s response to the projected climate in a given location

    “In the 20th century, we could pretty much grow the same things with confidence, we could learn from previous generations,” said Prof Sam Brockington, a curator at Cambridge University Botanic Garden.

    “But now we’re moving into climate scenarios that we just don’t have the traditions to understand fully.”

  • For the first time since 1937, no open permits to hunt ruffed grouse in Ohio have been issued due to falling numbers

    Every November, hundreds of hunters descend on four designated wilderness areas in southern Ohio in pursuit of the elusive ruffed grouse.

    But not this year.

  • Scientist Adalberto Luis Val’s pioneering research on the tambaqui fish is revealing the effect of climate disruption in Brazil, with global implications for biodiversity and food security

    As a boy in rural São Paulo, Adalberto Luis Val used to stare into the lake where his father took him fishing and wonder how all those creatures swimming below stayed alive. One day, he netted a few, put them in a jar, and brought them home to observe. The next morning, they were all dead. Val was devastated but intrigued.

    “I needed to know how fish are able to live,” he says.

  • The handover marks the end of a 13-year licence for Smart DCC, a subsidiary of Capita, after years of spiralling costs and delays

    Control over Great Britain’s 39m smart meters has passed to a non-profit startup after its former owner presided over more than a decade of spiralling costs and delays in the troubled network.

    The company owned by crisis-hit outsourcing firm Capita has promised a “seamless transition” to its not-for-profit successor, which will take over running the data network connecting the smart meters from this week.

  • With globe-spanning artists – including Charlotte Church doing angry electropop – the Flow project is hoping to make an impact at this month’s Cop31

    Amid tense and long-winded negotiations, and with the future of the planet at stake, emotions can often run high at Cop climate summits. But last year, when the annual conference arrived in Brazil, one UN official was unexpectedly moved to tears by five women singing about the power of water.

    “She gave me a massive hug after the event and said, ‘We need to bring music into Cop,’” says Nikita Llerena, the project manager for Flow, a music collective that’s hoping to bring art to the centre of the climate movement. What started as a handful of musicians meeting over Zoom last year has grown into a full-length album that unites female artists from around the world, including Charlotte Church, Maxine Peake and Nadine Shah. This month, members of the collective will return for Cop31, in Turkey, where they have been promoted to a slot at Global Cultural Action’s opening event.

  • At more than $52m, the race has become the most expensive in US history, but residents are fed up with flooding

    Aida Havel mulled her fate over coffee after working the early voting polls all day in Kill Devil Hills, North Carolina. “We are trapped,” she concluded.

    The Dare county commission candidate lives about 50 miles (80km) south, on Hatteras Island on the state’s Outer Banks.

  • Slušne halucinacije – ili slušanje glasova koje drugi ne čuju – pogađaju više od 70% osoba sa shizofrenijom. Unatoč liječenju antipsihoticima, otprilike 40% i dalje ima trajne halucinacije. Za ove pacijente hitno su potrebni novi pristupi liječenju.

  • Nova studija je otkrila da žene koje su češće jele hranu s visokim udjelom šećera imaju veći rizik od raka dojke, dok ni ukupni šećer u prehrani ni konzumacija voća nisu pokazali statistički značajnu povezanost. Voće je činilo oko 43% ukupnog šećera u prehrani, a prosječni unos šećera bio je 44 grama dnevno. Žene koje su konzumirale više od dvije porcije hrane s visokim udjelom šećera tjedno imale su 28% veći rizik od onih koje su jele jednu porciju mjesečno ili manje.

  • Protein koji sudjeluje u izgradnji zuba mogao bi se jednog dana koristiti kako bi se oštećenim zubima omogućilo da se sami obnove, pokazuju rezultati nove studije provedene u SAD-u.

  • Od otpornog škroba do staničnih stijenki biljaka, znanstvenici istražuju skrivenu konkurenciju i suradnju među crijevnim bakterijama, postavljajući intrigantna pitanja o tome što se događa s različitim vlaknima nakon što dođu do debelog crijeva.

  • U nedavno objavljenoj studiji znanstvenici su procijenili učinke konzumacije oraha na imunoglobuline (Ig) i antitijela usmjerena protiv lipoproteina niske gustoće modificiranih malondialdehidom (MDA-LDL). Nakon dvije godine, dugotrajna konzumacija oraha bila je povezana s ukupnim koncentracijama IgG-a u serumu koje su bile približno 6% više nego u kontrolnoj skupini, što upućuje na mogući utjecaj prehrane na cirkulirajuće imunološke biomarkere. 

  • Aorta se često prvenstveno smatra najvećom krvnom žilom u tijelu - izdržljivim kanalom koji dostavlja krv bogatu kisikom iz srca u svaki organ. No, sve više dokaza upućuje na to da je stijenka aorte također aktivno imunološko okruženje. Imunološke stanice koje se nalaze unutar ili su regrutirane u različite dijelove aorte mogu utjecati na to kako se ova žila razvija, prilagođava mehaničkom stresu i postaje osjetljiva na bolesti.

  • Međunarodna studija izvještava o 60-postotnom preživljenju bez progresije bolesti 10 godina nakon autologne transplantacije koštane srži, pružajući važne dokaze o trajnim pozitivnim kliničkim ishodima i dugoročnoj sigurnosti kod pacijenata liječenih zbog rane, teške sistemske skleroze.

  • Novo istraživanje pokazuje da osobe s glioblastomom imaju aktivnije trombocite – stanice koje sudjeluju u zgrušavanju krvi. Trombociti također komuniciraju s drugim stanicama i mogu utjecati na imunološku aktivnost. Hiperaktivni trombociti kod osoba s glioblastomom usporavaju djelovanje T-stanica koje se bore protiv raka, što može pridonijeti rastu tumora i napredovanju bolesti.

  • Prepune karotenoida i drugih bioaktivnih spojeva, klice brokule i mikrozelenje privlače znanstvenu pozornost. Karotenoidi su prehrambeni pigmenti koji doprinose boji voća i povrća te pomažu u nekoliko fizioloških procesa. Karotenoidi uključuju karotenoide provitamina A, poput beta-karotena, alfa-karotena i beta-kriptoksantina, te karotenoide koji nisu provitamin A, poput luteina, zeaksantina i likopena. Karotenoidi mogu utjecati na osjetljivost na inzulin, metabolizam lipida, adipogenezu i upalnu signalizaciju.

  • Zubna caklina je visoko mineralizirani vanjski sloj zuba. Caklina štiti unutarnje slojeve zuba od šećera i kiselina koje unosimo hranom, kao i od svakodnevnog žvakanja, grizenja i trenja. Ona je najtvrđe tkivo u ljudskom tijelu.
