Birdwatch, August - September 2017

Well summer is over, birding-wise, and during the last three months, hopefully, birds have bred successfully on the island. I have certainly seen evidence of this, particularly recently, with good numbers of House Sparrows all around. Also frequently during the summer months I have seen birds carrying food to nests.

We are keeping an eye out for bats, as they have been noticeably fewer over the past few years. Happily, there have been more around this year. On August 9th, at dinner with nearby neighbours, I was pleased to see quite a few bats of different species swooping under the lights of their swimming pool. There was a Nightjar too.

With some difficulty and not terribly good images but I managed to photograph an adult and juvenile Golden Oriole which nested nearby in Dol – last heard in very early September, in Dol and also in Vrboska.

Mid-September and I have seen a few birds of prey passing through, several Harriers, Honey Buzzard (a bird watching friend visiting picked up on that – I’m not so sure I would have picked it out ). We also saw a Short-Toed Eagle on two different occasions at two different locations. Was it the same bird?? Perhaps.

After the much needed rain I visited the pond on Stari Grad plain every day to see if this would bring anything new in but still very quiet. I was seeing Whinchats and still Red Backed Shrike, an occasional Cirl Bunting calling whilst picking grapes on 14th September. Also on two different days a Sparrowhawk looking to feed but sadly on both days it was unsuccessful while I was there.

On September 13th down at the Vrbanj airfield I saw the first birds actually feeding on the ground, the recent rain had clearly softened the ground, providing some food, I counted 16 Hooded Crows, probably in the region of 200 House Sparrows in various flocks, a Hoopoe – you can clearly see from the picture how pale it looks in comparison to the arrival earlier in the year.

There were also a few Wheatear and seven Tawny Pipits, once again passing through. I wasn't totally sure of the identification, but three people I asked for help all confirmed.

On the same day whilst watching from my garden I saw several Blackcaps both adult and newly fledged birds feeding on the figs. Also several Spotted Flycatchers. Then, another first for me on the island, no doubt just passing through as there's been no sign of it since – a Wood Warbler. For ages I had been trying to photograph a male Blackcap and female, to show the difference between them for anyone who wants to identify them. In mid-September they were constantly feeding on the figs, albeit really difficult to catch on camera. But I was fortunate on the afternoon of September 15th. The picture clearly identifies a male and two females, female Blackcaps having the “brown cap”. Couldn’t be any better than that to make a comparison.

On September 17th two storks came to earth in Jelsa. Immediate steps were taken by bird-loving friends of Eco Hvar to ensure that they would be given appropriate food and kept as safe as possible. They settled into a comfortable routine over the next few days. The rain which came down on September 20th provided a good source of insects, which they devoured with gusto. They also clearly enjoyed the fresh fish meals which were being provided at intervals during the day. Storks are generally gentle birds, and intelligent. They quickly realized that shopping bags could be bringing them their mobile meals, so they were prone to advancing on any innocent shoppers who were trying toload their bags into cars parked nearby. The only worry was whether they would get too used to this luxury lifestyle to resume their long journey to Africa. However, this is not the first time storks have appeared in jelsa at this time of year, and they have always moved on after a while, so we shall see.

By September 21st most other migrating birds had headed off. I saw a single Swallow the day before. Out on my bike on the morning of the 21st, I saw Yellow Wagtails and Tawny Pipits frequenting the airfield getting ready to move on, while there was nothing at the pond again.

  • Chief scientist says dangerous heatwaves, which are getting more likely, ‘bring home the implications of climate change’

    The month of June was the hottest in England on record, driven by a searing heatwave in the final days of the month, which for the first time had red heat alerts for three days, according to Met Office data.

    The Met Office said provisional statistics showed Wales and the UK as a whole had recorded their second-warmest June since 1884.

  • New study on fluazinam’s neurotoxicity comes up with different findings from earlier report based on manufacturer’s data

    Researchers who re-ran a crucial fungicide study on neurotoxicity have come up with significantly different findings, and campaigners argue that the substance should now be withdrawn from the market.

    In 2005, a study conducted by Huntingdon Life Sciences on behalf of ISK, the manufacturer of fluazinam, on the development of neurotoxicity of fluazinam in pregnant rats concluded there were no statistically significant effects in relation to brain development in the rats’ offspring.

  • Many seabirds are starving to death as a marine heat wave lingers off California and fish seek deeper, cooler waters

    Within minutes of walking on a San Diego beach, marine ornithologist Tammy Russell found the feathered carcasses – one after another.

    Some were mixed in with washed up kelp. Others were under rocks.

  • Poaching and wildfires have driven the country’s jaguar population to a critical level, and until now even rescued animals faced life in captivity

    A tentative paw emerged from a steel cage on to the sandy riverbed deep in the Bolivian rainforest. Then, another. Slowly, the female jaguar looked right, left and right again, as if waiting to cross a busy road. Then, muscles stiff from the long journey, it strolled away and disappeared into the undergrowth.

    Yaguara had been in captivity since August 2024, after being orphaned as an eight-month-old cub amid Bolivia’s worst recorded wildfire season. As the fires raged, burning more than 10% of the country’s surface area, authorities handed the cub over to a team of veterinarians from the Comunidad Inti Wara Yassi (CIWY), a wild-animal rescue centre.

  • Wildlife at risk as demand for cropland and water grows to feed 50% rise in farmed animals, campaign alliance says

    The number of mammals and poultry farmed worldwide has increased by half in the last two decades, research shows, and the amount of cropland used for feeding livestock has increased by about a quarter.

    These increases are putting rising pressure on natural systems, threatening wildlife and plant species and adding to the climate crisis.

  • Reasons for increase not clear but experts say it could be welcome sign marine ecosystem is becoming healthier

    The Farne Islands off the Northumberland coast have long drawn fans of the natural world keen to catch sight of the resident guillemots and puffins.

    But as recently as last week, another much bigger black-and-white animal has been delighting wildlife spotters. Orcas have been appearing more regularly than ever before.

  • Study shows falling dust levels are making clouds more reflective, an effect not taken into account in climate models

    Cleaner clouds are helping to slow the rate of global heating, a study shows. Falling levels of dust in the atmosphere are making clouds more reflective. This previously unidentified effect is not being taken into account by current climate models, which may mean they are slightly overestimating the projected rate of global heating.

    Researchers analysed satellite observations of high clouds in the northern hemisphere and assessed the ratio of ice crystals to liquid droplets over the period 2008 to 2018. Their findings, published in Geophysical Research Letters, show that clouds have become less icy over that time. Weakening surface winds (due to climate change) have resulted in less dust being whipped up into the atmosphere over the last two decades. Dust particles help to seed ice crystals, so less dust means fewer ice crystals in clouds. The effect is not observed in southern hemisphere clouds because there is far less dust in the southern hemisphere atmosphere in the first place.

  • After a recent study found New Orleans is at a ‘point of no return’ amid the climate crisis, some locals say they will ‘only leave if forced to’. But what would it take to stay?

    When a study in May concluded that New Orleans had hit a “point of no return” due to the climate crisis that would require people to eventually retreat from their storied yet ultimately doomed city, the local reaction was swift and fiery.

    The onward march of rising seas around a sinking city was unsettling, but the study was “more focused on generating publicity and clickbait headlines” than coming up with solutions, said Helena Moreno, New Orleans’s mayor. There was flooding in Miami, and wildfires and earthquakes near San Fransisco, Moreno pointed out, “yet no serious movement exists to declare those cities lost causes”.
