Nesting swallows: good luck promised!

Marion Podolski has the good fortune to have swallows nesting in her doorway in Vrboska on Hvar. Exciting and fascinating!

16th June 2017. I’m happy to report that the good fortune of our house is assured for the summer at least. This is due to the presence of a little swallow family nesting in the porch by our front door. We did try to explain to them that it wasn’t the quietest of locations, but neither parents nor babies seem particularly disturbed by our coming and going. And so, we have the privilege of watching this little brood develop at close quarters.

These are barn swallows, Hirundo rustica, as most European swallows are. They’re known locally as Lastavice, arriving on Hvar during April/May, along with their close cousins, the house martins. Vrboska provides a very suitable habitat for both, having an ideal source of mud for nest building in the upper harbour, and plenty of flying insects in the surrounding fields. We really appreciate the birds’ help in keeping down the mosquitoes!

I’m learning to tell the difference between swallows and martins, especially in their home life. What I thought was a rather unfinished nest in our porch turns out to be the typical open-cup shape built by swallows. It’s high up in the corner of the wall, built from gobs of mud. This is in contrast to the house martins more enclosed nest with entry hole, tucked up under the eaves of many a village house. And while the martins may build a row of nests together, the swallows tend to be more individual. Though I do understand that the next generation likes to nest near where they grew up, and our porch does have four corners!

We currently have four chicks in our nest, as I’m sorry to say that we lost one overboard during the week. It seemed in fine shape and pretty well fed, but unfortunately had not survived the fall when we found it on the step. We gave that one a decent burial, and have set a camera to monitor progress on the others and try to keep them safe.

Looking at today’s photos, I see that the chick on the left has open eyes and a feathery halo on its head! And they all have gaping mouths when Mum or Dad arrives with food, as they do often throughout the day.

For swallows, eggs typically take between 14 to 21 days to hatch. The newborns are naked with closed eyes, which take up to 10 days to open.Within 17-24 days these babies will fledge, but will still hang around the nest site to be fed by Mum and Dad for a while. More photos to come.

To be continued as things develop…

Nesting swallows, part 2, 18th June 2017: growing feathers

A quick update on our Barn Swallow nestlings, as I’ve just been outside to check with the zoom lens. They certainly are growing fast and look much more alert! It’s now very clear that they have their eyes open and feathers are growing. And is that a tinge of russet colour?

I can tell from the step below that nobody has fallen out so there must still be four in the nest, but I’m relieved when #4 at the back stretches and shows its wee beak. Everyone is safe. I can get on with clearing up the crap below them!

There's number 4! Photo: Marion Podolski

Nesting swallows part 3, 20th June 2017: real little birds now

Our little chicks are developing rapidly into miniature versions of their parents! Their wing feathers are almost completely in, although the tails are still stubby little markers for the graceful long forked tails of adulthood.

As I stand quietly in the shade of the opposite doorway, one of the parents checks me out carefully. No doubt I’d have been in trouble if I tried to approach the nest more closely.

He/she was also offering me a nice view of the subtle colouring on the chest, and the underwing. I really can’t tell without seeing the tail whether this is Mum or Dad. We have strapped up a security camera on a coat rack, which gives us a view of the activity on the nest without encroaching on their privacy. It’s wide-angle, so not quite the resolution we’d like, but, hey, not bad for an impromptu nest cam! Here are some examples:

As the chicks grow, they seem increasingly crowded on the nest. They’re kind of piled up on top of each other by now.

Just like real birds. Photo: Marion Podolski

Which makes it all the harder for them to be testing out their wings in preparation for the big first flight, which must surely be coming any day now. I watched one climb to the top of the pile and flap away for a while, somewhat hampered by its siblings.

And after its workout, a little stretch and a preening session to take care of the feathers!

Nesting swallows part 4, 23rd June 2017: testing wings

Our little swallow chicks are still on the nest, although there’s been plenty of flapping going on. We’ve taken to watching them on our nestcam, as they go very still and flat when we open the door. Not so interesting to watch! Here are a couple of photos, though, to show what a difference a few days makes. First is feeding time (20 June).

And here they are a few days later, piled on top of one another. They’re looking much sleeker, and have clearly been looking after their new feathers. The face patterns are now individual and I’m guessing that big guy is the oldest, as he seems to be rather larger than the sibling alongside. And you can just make out the other two underneath.

Still waiting for that fledging moment…

Nesting swallows part 5: 23rd June 2017, Taking to the air

After watching the nest remotely for a few days, I was thrilled to catch sight of a chick take flight from the nest and land on the nearby light. That was Saturday 23 June, at 8:26am. The new fledgling was fed by a parent there, looked around for a while and returned to the nest, where it landed on top of its siblings! Yay! A successful first flight!!

If I hadn’t seen it happen on the nestcam, we would not have known. For the rest of the day (a roasting 34 degrees C) all four chicks were piled on the nest as usual. And then this morning, this.

An empty nest. Arghhhh! Did we completely miss the rest of the babies taking flight? Where’d they go? But I can still hear them and there seem to be rather a lot of swallows flying around in our courtyard. Ah, there they are!

Our porch light is a handy platform! From there, they ventured out to practise their flying again. From time to time they land on the wire, where I managed to catch a quick family portrait with one parent and 4 chicks.They are clearly smaller, and have not yet grown their long V-tails.

Here’s a better close-up of three of the youngsters, looking like real swallows now. They were watching their sibling practise his aerial skills.

He can fly pretty well already, but the landings definitely need work. Always the hardest part of learning to fly, I guess! Here he’s managed to park himself on the neighbour’s roof.

Now that’s better! A nice clean landing perched back on the wire. That seems to be the new feeding station, and the parents will still feed them for some days to come. And very soon they’ll be catching their own insects.

I wonder when the parents will start another round? Please let me get my porch clean again first!

  • Iran war has increased gas price, with effects on UK energy bills that could be avoided, Common Wealth says

    Household energy bills could be reduced by up to £203 a year by stopping expensive fossil gas setting the price of energy in the UK, according to a report.

    Under the existing system, gas – the most expensive form of electricity production in the UK system – set the price of energy 85% of the time in 2024 in the UK, even though it generates only about a quarter of Britain’s electricity.

  • Move will put national security and lives overseas at risk, critics say, as overall UK aid budget is slashed to 0.3% of gross national income

    Climate aid to developing countries from the UK will be cut by about 14% to roughly £2bn a year under government plans, in a move critics said would put national security and lives overseas at risk.

    The move follows bitter rows with the Treasury, which wanted deeper cuts owing to pressure on spending resulting from the war in Iran.

  • Trillions of insects embark, largely unnoticed, on epic journeys every year across mountain ranges, deserts and seas, and it is only now, as their numbers suffer huge declines, that scientists are tracking their movements

    On a cloudless sunny day in October 1950, ornithologists Elizabeth and David Lack stood on a mountain pass in the Pyrenees and observed a once-in-a-lifetime spectacle – clouds of migrating insects.

    Up to 500 butterflies were fluttering past them every hour through the 2,200m-high Puerto de Bujaruelo mountain pass on the French-Spanish border. By mid-afternoon dragonflies were skimming through, outnumbering the butterflies by 10 to one. The spaces between were filled with thousands of tiny flies.

  • Exclusive: finding out who owns land will become simpler under plans to make the best use of green spaces and hit net zero targets

    Finding out who owns land in England is to become much simpler because a paywall will be lifted from large parts of the Land Registry, the government is to announce.

    A small number of landowners control the majority of land but finding out who owns what is difficult to piece together, even for government departments, owing to the way the Land Registry operates. Freeing up access will make it easier to determine ownership of key areas, such as river catchments, grouse moors and peatland.

  • Frome, Somerset: A small patch of land, leased by the council, will be the site of a new community project. And so we descend, ready to rewrite its future

    Who crawled along Snail’s Bottom? Who found beauty on Bonnyleigh Hill? Who measured Little Acre Farm? This small patch of Somerset – like everywhere else in Britain – is a storied landscape, every feature named and memorialised by mostly forgotten individuals. Our job over the next two hours is to take one such name, one such story, and overwrite it with something better.

    Over a level crossing, through a kissing gate and on to a public footpath running down sloping ground. I had only been told the local epithet for this banana-shaped paddock after we moved here, though my arm already understood its origin. A priapic stallion, its coat studded with burdock burrs like a peppered mackerel, had clamped its jaws around my humerus. “That’s bitey horse field,” people told me. Bitey no more, for the poor fly-grazing beast has left, and our ever-proactive town council has secured the land on a 99-year lease.

  • Perhaps the biggest surprise is that it tricks ants into moving its seeds with a scent that mimics their larvae

    Plants are superb at enticing animals to pollinate their flowers or carry off their seeds. But one plant co-opts an astonishing combination of fire, bees and ants to mastermind its reproduction.

    The South African Natal crocus, Apodolirion buchananii, has a gloriously bright white flower that emerges from the ground before its leaves appear in early spring. But the flower only blooms shortly after fire breaks out naturally in its native grasslands, leaving it standing like a beacon among the blackened grass to help lure bee pollinators, with an irresistible sweet scent that wafts through the air.

  • Exclusive: Fixing a leak can be simple and equivalent to closing a coal power station, making lack of action maddening, say analysts

    The world’s worst mega-leaks of the potent greenhouse gas methane in 2025 have been revealed by an analysis of satellite data.

    The super-polluting plumes from oil and gas facilities have a colossal heating impact on the climate but often result from poor maintenance and can be simple to fix. The assessment found dozens of mega-leaks, each having the same global heating impact as a coal-fired power station.

  • Puffins, guillemots and razorbills are being washed up dead or dying on Europe’s Atlantic coast in what scientists call a ‘wreck’

    Thousands of seabirds – mostly puffins, but also many guillemots and razorbills – are being washed up dead or dying on the Atlantic coasts of western Europe, in what scientists call a “wreck”.

    This year’s events, the consequence of a series of severe storms during the late autumn and winter, are the worst since 2014, when as many as 54,000 birds were found stranded. Of these, well over half – between 30,000 and 34,000 – were puffins.

    Eight years before he got the call telling him he had won the Stockholm water prize, Prof Kaveh Madani was being interrogated by Iran’s Revolutionary Guards, accused of being a spy for the CIA, MI6 or the Mossad.

    Today he is in exile and on Wednesday won the world’s most prestigious water prize for combining “groundbreaking research on water management with policy, diplomacy and global outreach, often under personal risk and political complexity”.

  • As the hit travelogue about the worlds beneath us becomes a film, its maker takes us on a voyage through Las Vegas storm drains and the caves of Yucatán – via Goatchurch Cavern in the bowels of Somerset

    Just off the B3134 in Somerset is a portal to the underworld. The smaller of two openings to Goatchurch Cavern, it’s called the Tradesman’s Entrance – and through it I am squeezing. After tumbling on my bum over damp smooth rock, lacerating a jumpsuit in the process, I venture down and down, sometimes crawling, sometimes standing upright, trying to find footholds in the dark.

    I’m here with film-maker Robert Petit, so he can show me something of what he’s been experiencing for the past five years, on his way to making an endearingly poetic documentary film called Underland, which riffs on nature-writer Robert Macfarlane’s bestselling 2019 subterranean travelogue of the same name. We’re heading 100ft underground to the Boulder Chamber where, over sugary snacks, I will quiz him about his obsession.
