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.

  • Exclusive: Fighting Dirty taking legal action against government over proposal it says could import weaker standards

    An environmental campaign group is taking legal action against the government over proposals that it claims could fast-track chemical hazard classifications from other countries with lower standards into UK law.

    Fighting Dirty claims proposals to change the classification and labelling of potentially hazardous chemicals could result in the UK weakening standards on cancer-causing substances.

  • Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration

    Trees may not be able to store as much planet-heating carbon as hoped, a study suggests, with researchers finding photosynthesis does not always lead to wood growth.

    Scientists studied 137 sites across the US and found trees stopped growing months before the point in the year at which photosynthesis stopped.

  • ExclusiveA vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’

    Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.

    One expert said the loss of ice in the Bellingshausen Sea was “depressing” and the failure of ice to form could have intensified a heatwave over the continent’s peninsula last week that saw daytime temperatures peak at 15.4C which is more than 20C above average.

  • Appearance of a western reef heron in north Wales is unlikely to be the last, as heating temperatures mean species can survive Britain’s winter, say experts

    It is a tropical bird typically encountered between west Africa and India, but last week a western reef heron arrived in north Wales in what is believed to be the first ever sighting in the UK.

    The heron was first spotted in Foryd Bay at the weekend before flying to nearby Caernarfon harbour where it fed among the boats.

  • Wolsingham, Weardale: These stunning butterflies are here in incredible numbers this year, yet what’s most remarkable is their multigenerational migration

    There’s a painted lady basking on the footpath. Her orange, black-tipped, white-spotted wings, a little worn after her long journey, blend with shadows and sun-flecks on heatwave-baked mud, so she’s almost under our feet before she takes flight. And here’s another, nectaring on a dandelion; and another; then several more. I can’t recall ever seeing so many so early in the year.

    Waiting for the arrival of these migrant butterflies is akin to anticipating the first swallow. Tantalising mid-April sightings from Wales and Cumbria were reported on social media, but we waited until mid-May before finding our first in Weardale.

  • Imperial College scientists analysed health records before and after introduction of air pollution reduction zones

    Low emission and clean air zones attract controversy whenever they are proposed, but there is growing evidence that they work in improving air quality. The Bradford zone was followed by a reduction of about 25% in GP visits for heart and breathing problems and survey data shows that the central London zone was followed by a reduction in the likelihood of a person taking sick leave.

    Now analysis of health records has found emergency admissions to hospital reduced after the introduction of the T-charge and ultra-low emissions zone (Ulez) in central London.

  • Two fires in 12 years wiped out all but a handful of the mature native pines in Victoria’s Wyperfeld national park, a key breeding ground for endangered pink cockatoos

    At the entrance to Wyperfeld national park, in north-west Victoria, more than a dozen pink cockatoos are sprinkled across a hedge row of pine trees like Christmas decorations. These are Aleppo pines, not the native conifers that the birds rely on for nesting habitat and as a primary source of food.

    Still, the feathered ornaments appear quite content, nestled in among the spruce and ripping into pine cones with their dexterous claws and beaks, making gentle cracking sounds that punctuate the soft roar of Mallee winds.

  • With limited resources and sanctions tightening, conservationists are forced to find new ways to protect the coral reefs of Ciénaga de Zapata national park

    At 8am, scuba divers gather to collect plastic and drinks cans from the sea at Cuba’s Ciénaga de Zapata national park. Amid a power crisis that has virtually paralysed the country’s economy, they use an electric trailer to move to a designated spot. In only a few hours, they have collected five sacks of cans and waste.

    Lack of environmental awareness, invasive species and the climate crisis have long threatened the island’s pristine marine ecosystem but as US sanctions and economic scarcity take their toll on the country, scientists and community conservationists are working with even scarcer resources to protect a vital ecosystem for the Caribbean and the world.

  • Despite plunging border crossings, the Trump administration is circumventing laws to expedite building in a vast, pristine wilderness

    The Trump administration has waived a slew of environmental and historical preservation laws that would allow it to build a towering border wall that cuts through Big Bend national park, a vast protected wilderness in south Texas.

    Congress poured a whopping $46.5bn for border wall construction into the “Big, Beautiful” bill last year, supercharging Donald Trump’s ambition to wall off the southern border with Mexico. The longest unwalled stretches lie along a roughly 500-mile (800km) section of west Texas that Customs and Border Protection calls the “Big Bend sector”.
