Birdwatch & Insects, Autumn-Winter 2017

Steve Jones rounds off the year, puzzled by the absence of some birds he expected to see.

As we came into Autumn there was the expected movement, with lots of finches appearing, predominantly Chaffinch, Goldfinch with a few interspersed Serin, feeding on seed heads. I am always on the lookout for Brambling amongst the Chaffinch but it seems I have to make to do with the two sightings in early January. The Serin pictured below was at the pond (which still had very little water after the hot dry summer). The picture came out better than I was expecting, even though I was looking into the sun. I think it is probably a male in winter plumage, which becomes incredibly bright in Spring time.

October 13th: Still seeing odd Swallows and this morning a Swift. Lots of Wagtails on the airfield, up to 50, and this week a big movement of Stonechats which I didn’t notice at all last year. I've seen 30 - 40 at various locations this week. I was very pleased with this picture of the goldfinch / gardelin - you really don't get too much closer than this. I took about 20 shots this morning, slowly edging closer, shielded by some grape vines.

In October, 'Nature' journal publicized a report from Denmark1 showing changes in breeding patterns as well as a decline in numbers of starlings (sturnusa vulgaris) in a long-term study. Over 45 years from 1971 to 2015, dairy farmer Peder V. Thellesen logged the habits of the birds, which had 27 nesting boxes on his property2. The changes are attributed largely to climate change, and give cause for worry. Similarly, I know of in-depth studies of curlew on Dartmoor, which have suggested that curlew in the south of England could be extinct within 7 years, unless something is done. the situation is complex, but in this case predation is apparently the biggest problem.

October 18th: I saw a Swift two days ago at Jelsa fire station. There are still lots moving, most notably Stonechats. I have also seen several Pipits, but have not been able to get anywhere near close enough for a decent picture. Sparrow Hawks have been about regularly, but again they have escaped the camera. Robins are back in large numbers, and they are the most prominent singers at the moment. Robins may well be here throughout the year, but if they are, they're certainly not obvious.

October 19th: There was a flock of 20 plus Starlings at airfield this morning. Oddly, I hadn't seen one in all the time I had been going there until January/February of this year (I even mentioned this when we did an interview for the magazine Dobra Kob at the beginning of the year). And now this is the second lot I have seen this Autumn. What a surprise!

Towards the end of October I had another first for me and the island – Wood Lark, there were up to seven on the airfield for around a week.

Blackcaps seemed to be actively feeding on the remaining figs. I did manage a glimpse of another new species, a Firecrest.

Stonechats were clearly passing through for about 10 days, I saw them regularly regularly down near the pond. Up to 50 Pied Wagtails were on the airfield amongst occasional pipits and Yellow Wagtails, and I was still seeing the odd Swallow and Swifts well into October. (A Grey Wagtail was often to be seen in Stari Grad, but he has not provided me with a decent picture). It's worth noting that 'pied wagtail' used to be the general term for two groups of birds which were very similar, whereas nowadays it's more usual to differentiate between 'pied wagtails' and 'white wagtails'. In fact most of the the ones on Hvar are white wagtails.

The latter part of October saw the arrival of Great Tits and Blue Tits. Sparrowhawks and Buzzards were also seen now on an almost daily basis, but both were extremely uncomfortable near the camera.

October 29th: I am 99% sure I had a Goldcrest the other day. I am not 100% certain, but fellow bird-watching enthusiast John Ball had a definite sighting with a fine photograph to prove it on October 13th, from the beach by the Senses resort in Vrboska, where he was staying. So Goldcrest is included in the year's list of sightings, bringing the total to just above 90 species for the year. Say I miss about 10% the true figure could be close to 100 species for the year.

This week saw the return of Black Redstarts (I first saw them on 2nd November last year, 2016). There were still Tawny Pipits on airfield and at last I managed a picture this week - not a brilliant one, but good enough for certain identification.

 Common Darters (dragonflies ) are laying / mating at the remaining water in the pond.

The Grey Wagtail keeps escaping the camera in Stari Grad but I have been seeing and hearing it most days now. Yesterday I saw good numbers of Clouded Yellow butterflies, but as for getting one on the camera ........... Ummmmm.

In November I started using the little bird feeding station I had created. Initially it was all very quiet, but once they got used to the food they started to come in numbers. I was inundated with Great Tits - up to 20 at one time -, also Blue Tits and Chaffinch.

A very occasional Dunnock appeared, also a Wren (but I have not been lucky enough to get a decent photograph of him yet). There were a few Black Redstarts around, but they didn't come to the feeders.

In early December I was delighted with another new species on the Island - Hawfinch. I had only seen one briefly in the UK once before. I managed to see three in the following days, but not close enough for a picture, until I managed this on the 12th December.

December 19th. My feeding station has proved to be very successful, I could easily get rid of 1kg of bird food in a day (and at 18 kuna a kilo I am rationing it somewhat)!! It is interesting how the birds come in waves, appearing in grouops of 20 - 30, although there are mainly just three species. They feed just for a few minutes and then are gone. I suspect it is a strategy to fool the neighbouring cats, as three have taken to lying in wait at the bottom of the feeder or in a tree nearby.

I have still been hearing the Wren in the neighbourhood, but he's escaped the camera so far. I am sure I will get a picture at some stage during the winter. As we passed the shortest day you may well have noticed how the Blackbird was more prominent, starting to feed on the ivy berries. Before long they would be actively singing as the New Year begins………………. Bringing with it another list of bird species sightings!

With the end of another year upon us, it seems I have to settle for 93 species sighted in 2017, not the 100 I had been hoping for. I accept from the areas I cover I could have missed several species, but on balance, given the frequency with which I have visited “my patch” I am happy with what I have recorded. I don’t do any sea-watching – for no other reason than on the times I have tried, it has offered little, which is surprising. I am also puzzled as to why certain “common” species aren’t seen on the island, such as Magpie, Jay, Crow and Jackdaw, which I was used to seeing in large numbers in the UK. However, here there are lots of Hooded Crows, which are very apparent at the moment, so maybe they do the job of all those others. I also have not seen Long Tailed Tits or Coal Tits at all, and Blue Tits are rare, appearing only in single numbers. I am planning a couple of trips to the mainland in 2018 for some bird watching – it may just be to do with the location of the island.

  • Accumulation on Switzerland’s glaciers from last winter expected to all be gone by Monday amid ‘enormous’ melt rates across Alps

    Swiss glaciers are set to lose an enormous amount of ice due to the heatwave battering Europe, according to the head of Glacier Monitoring in Switzerland (Glamos).

    The snow and ice accumulated last winter by Switzerland’s glaciers is expected to have all melted away by Monday, marking the alarming second-earliest arrival on record of the tipping point known as glacier loss day.

  • Experts worked in ocean midwater off Brazil at near-record speeds thanks to cutting-edge tech

    A marine biology expedition in international waters off the coast of Brazil has discovered 31 new species in just two weeks.

    The researchers believe the speed at which the species were found and identified may be a record, in part because of the cutting-edge technology designed and built by the science and engineering team. For the first time on board a ship, the researchers were able to observe the living 3D cellular structure of microbial life thanks to a technological breakthrough nicknamed the Squid.

  • Edinburgh:As we are visually impaired, we love to appreciate the sounds and smell of the woodland. This time it had been raining, so we could smell the wet ground

    Our school, the Royal Blind school, Sight Scotland, is across the road from the Astley Ainslie hospital. The hospital gardens are open to the public and have over 2,000 trees, and sometimes we go to there for outdoor learning lessons with Margon, who helps us learn about the outdoors.

    Recently we went to a wooded area to make a den for shelter. We could see lots of green everywhere. It had been raining but we could feel the warm sun and smell the wet ground, which was spongy and soft under our feet. It had been windy and there were twigs and leaves on the ground. We found a tree with textured bark that felt like veins. Margon told us that the bits we could feel were old ivy vines. We could hear lots of birds and feel the breeze and hear it rustling the leaves.

  • Three pumped storage hydroelectric power station sites in Scotland on list of 16 long-duration electricity storage plans

    Great Britain’s first new major hydropower projects in more than 40 years are expected to move ahead after the energy regulator gave a provisional green light to three proposals as part of a plan to reduce the country’s reliance on energy imports.

    All three of the new pumped storage hydroelectric power station projects are due to be built in northern Scotland, where the region’s lochs will act as natural reservoirs to serve the hydropower stations.

  • Emerging research suggests datacentres create a heat island effect, pushing up temperatures in the immediate vicinity by as much as 9C

    The community living next to the largest datacentre park in Europe say the scorching summer heat has grown unbearable.

    On days like Wednesday, said Nabeel Nawaz, the store manager of a Chaiiwala franchise in the centre of Slough, the heat is like something “pinching your body and burning your skin”.

  • The H5N1 virus has now reached every continent on the planet. What does it mean for some of the world’s unique species?

    It was a rough five-day sail from the Falkland Islands and, as the science expedition approached the South Georgia coast, they found fur seal carcasses floating on the water. “There were these moments when it would hit us,” says Dr Jane Younger, remembering the expedition to the British sub-Antarctic territory six months ago.

    Younger, an ecologist at the Institute for Marine and Antarctic Studies at the University of Tasmania, was with scientists from the United States, France, South Africa and the Falklands to check on the spread of the H5N1 variant of bird flu.

  • The CLP’s ‘tough on crime’, pro-development agenda brings sweeping changes, which advocates say cut the NT’s most vulnerable out of the conversation

    The Northern Territory is out of sight – and often out of mind – for many Australians. But for 18 months, environment, First Nations, justice and family groups have been sounding the alarm with increasing urgency.

    The populist, “tough on crime” agenda which saw the Country Liberal party, led by Lia Finocchiaro, sweep to power in 2024 has been taking shape, and those representing the territory’s most vulnerable people, communities and ecosystems are worried.

  • As temperatures soar across Europe, cities are struggling to adapt, further exacerbating socioeconomic divisions

    The heatwave afflicting western Europe is the worst ever, with the combination of heat and humidity fuelled by the climate crisis making scores of cities feel unliveable. While for some the adverse impacts amount to disturbed sleep and sticky days in the home office, low-income families are often worse affected by cities’ lack of adequate adaptation measures, with women at the sharp end.

    “[It] throws a grenade into every vulnerability you already have,” says Asad Rehman, chief executive of Friends of the Earth, pointing out that vulnerable or marginalised groups often bear the brunt of climate crisis-based hardship globally.
