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.

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!

  • UN agency predicts phenomenon that supercharges weather extremes has 80% chance of forming before September

    The world must prepare for the imminent return of El Niño and the supercharged weather extremes it brings, the UN has warned.

    The powerful natural weather pattern, which raises global temperatures and worsens some rainfall, has an 80% chance of forming before September and a 90% chance before November, the World Meteorological Organization (WMO) said on Tuesday.

  • Kielder in Northumberland is balancing commercial production with conserving peatland and rare plants and animals

    Driving through part of Northumberland, you might look around at the tall Sitka spruce and imagine yourself in Canada’s evergreen forests, or perhaps, on a sunny day, in northern California. Instead, you are in England’s largest forest, Kielder, often heralded as a success story that balances commercial production with ambitious conservation.

    The first trees of this 60,000-hectare forest were planted 100 years ago with one aim: increasing Britain’s timber reserves. Much has changed since then. From a single-use plantation, Kielder Forest has been transformed into a haven for nature and an invaluable environmental asset.

  • Novel forms of CO2 removal must expand at ‘highly ambitious rates’ if world is to limit global heating to 1.5C, says study

    Humanity must suck carbon out of the atmosphere with new technologies even faster than the breakneck speed with which it has deployed solar panels if it is to limit global heating to 1.5C, a report has found.

    Novel forms of carbon dioxide removal (CDR) must grow at “highly ambitious rates” to bridge the gap between what governments have pledged to clean up and what is needed to comply with the Paris climate agreement, according to researchers. They said the next five years were critical to establishing the technologies’ role in limiting climate damages.

  • Net zero industry accounts for more than a million jobs and benefits whole country, according to CBI Economics

    More than a million jobs, higher wages, nearly half a trillion pounds in investment in the pipeline – the UK’s green economy is powering ahead, according to research by the country’s leading business organisation.

    The net zero economy, which is worth more than £100bn a year, benefits all of the UK, according to the CBI Economics analysis commissioned by the Energy and Climate Intelligence Unit thinktank, despite critics who want to abolish the UK’s net zero targets.

  • Scientists believe they may now have found the cause of Fair Isle’s pollution – and warn that it should be ringing alarm bells in other coastal areas

    When the wind picks up on Fair Isle, Britain’s most remote inhabited island, puffs of seafoam start to drift across fields like tumbleweed. The pale yellow blobs are ubiquitous enough to hold their own place in the island’s mythology: known as the butter churned by a local troll, Lukki Minni.

    “When the Atlantic gets going, foam covers the whole island,” says Tommy Hyndman, an artist who moved to the Fair Isle from upstate New York two decades ago. “Your windows get caked and your plants all die from the salt.”

  • Hogshaw, Derbyshire: We’re up to 27 spotted orchids in our garden, and every one is a miracle

    When we moved to this house, we didn’t need the encouragement of No Mow May – the ecological campaign advocating restraint in the garden. Our old lawnmower was designed to tackle your average handkerchief and leaving nine-tenths of the new place uncut was a matter of necessity as much as self-control.

    The highlight of last year’s non-labouring efforts addressed directly the whole meaning of no-mow gardening. Who knows what lies hidden in a uniform shorn expanse, unless it is allowed to express itself? A slender pink flower among the green swathe turned out to be a spotted orchid, the commonest, most widespread of our 54 UK species. With this as a search image, I eventually climbed to 16 spikes last year. That alone felt like a triumph.

  • From cliff sides, coastal lookouts, kayaks or boats, people counted every dolphin they saw for at least 15 minutes to aid research into NSW’s populations

    Looking down the barrel of a telephoto lens, Dr Elizabeth Hawkins tells the dolphins circling the research boat to work it for the camera.

    “That’s it,” she says, joking to her crew. “Show us some fin. Don’t be shy. How about some tail? Oh that’s good. The camera loves you.”

  • Physical and psychological impacts of a tap water parasite outbreak continue to be felt in south Devon

    Most of the tourists milling around the busy fishing harbour or visiting Agatha Christie’s riverside holiday retreat have probably forgotten what South West Water euphemistically calls the “Brixham incident”.

    But for residents at the centre of the “incident” – a parasite outbreak that caused perhaps hundreds of people in south Devon to fall ill after they drank contaminated water – the physical and psychological impacts are still keenly felt.

  • Pauline Hanson wants the government to take a stake in resource operations. While experts say this may sound reasonable, the devil’s in the details

    In September 2022, Pauline Hanson stood up in the Senate to berate the chamber – but she was’t fired up about immigration or the latest battle in the never ending culture wars.

    The One Nation leader was arguing for gas and oil exploration laws to change “to make the benefit of the Australian community a guiding principle in the interpretation of the act”.

  • Investigation reveals regulator let firms off the hook on cleanup bonds despite backlog that will take decades to clear

    When Christiaan van Woudenberg moved to Erie, Colorado, in 2007, he never imagined he would become an anti-fracking activist. He simply thought he was buying his dream home – a four-bedroom with a panoramic mountain view, 30 minutes north of downtown Denver.

    Then, in 2014, the drilling started. Oil and gas rigs sprang up, some just 800ft (240m) from his bedroom window. The dream turned to nightmare: loud noises rumbled all night long, and the air stank like exhaust. Neighbors started getting headaches and nosebleeds, and Van Woudenberg developed new respiratory issues. He kept his windows shut and worried about his daughters going outside.
