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!

  • Simon Stiell said burning fossil fuels was driving intense heatwaves as UK and France broke temperature records on consecutive days

    The UN climate chief has said an extreme early heat event sweeping parts of western Europe was “a brutal reminder of the spiralling impacts of the climate crisis”, after France and the UK set new temperature records for May on two consecutive days.

    Simon Stiell, the executive secretary of the UN Framework Convention on Climate Change, said on Wednesday the “main culprit” was humanity’s burning of coal, oil and gas – known to be the primary driver of climate change.

  • Researchers racing to document Oceania’s last tropical glaciers found the remaining ‘eternal snow’ in Indonesia’s West Papua region has lost almost all its ice

    An expedition to document the end days of the last tropical glaciers in Oceania has revealed sombre footage of “planetary destruction on fast-forward”.

    The once-mighty ice sheets on Puncak Jaya, a mountain surrounded by dense rainforests in West Papua, Indonesia, have survived beyond projections they would disappear by 2026 but have shrunk to a fraction of their original size.

  • At least nine people have died in recent days as people have tried to cool off in Britain’s waterways

    Water safety experts have warned about the dangers of outdoor swimming after a number of drownings in recent days as people try to escape soaring temperatures by cooling off in rivers, lakes, reservoirs and other bodies of water.

    Emergency services have reported at least nine deaths because of water-related incidents in the past few days, seven of them young people, as Britain’s heatwave sends crowds of people to the seaside and other swimming spots.

  • Investigation finds number of dairy farms where cows cannot go outside has more than doubled since 2015

    There has been a huge rise in factory-style dairy farming of “battery cows” in the UK as farmers struggle with increasing costs and face selling milk at a loss.

    The number of intensive dairy farms that permanently confine some of their cattle indoors has more than doubled in the past 10 years, an investigation by the Bureau of Investigative Journalism (BIJ) has found. Data suggests there are now at least 180 dairy farms where cows have no access to the outdoors, up from about 70 in 2015.

  • Calaminarian grassland is a rare habitat where plants thrive in soils contaminated by heavy metals. But should these toxic meadows be protected or allowed to fade away?

    At first, the small purple flowers are hard to spot in the weak May sunshine. Slowly the drifts of delicate mountain pansies, along with the white rosettes of alpine pennycress, begin to jump out, scattered across an area little bigger than a football pitch, on the banks of the River Allen in Northumberland.

    This is a pocket of calaminarian grassland, an increasingly rare habitat where specialist plants called metallophytes have adapted to live in soils deeply contaminated by heavy metals, the legacy of more than 1,000 years of lead mining.

  • Experts say climate change linked to 10% rise in salmonella antibiotic resistance genes between 1940 and 2023

    The climate crisis is accelerating a global increase in antibiotic resistance that poses a serious threat to human health, experts have said as figures show a rise in salmonella antibiotic resistant genes.

    Antibiotic resistance is one of the fastest-growing threats to global health. It can affect people of any age in any country and already kills more than 1 million people a year, according to estimates.

  • Swanage, Dorset: While the seabirds here make the headlines, my eye is drawn to the unassuming rock pipit and its accelerating song

    It’s a stunning evening for a walk at Durlston Country Park. The position of its headland on the south-west coast of England makes it a fantastic place to watch bird migration in action. As I walk along the coastal path, enjoying the panoramic sea views, barn swallows arrive from across the Channel.

    Below is a cacophony of sound coming from the cliff edges; this part of the Jurassic Coast is home to a breeding colony of seabirds, with last year’s survey recording 1,377 guillemots, 179 razorbills, 12 fulmars and just six puffins.

  • Like so many Britons, I usually consult a weather app before venturing out of the house – and often cancel plans if I don’t like what I see. Here’s what happened when I went cold turkey for a week

    When I heard on the radio that more than half of British people would consider cancelling an outing if they saw a 40% chance of rain all day on their weather app, I felt seen. I, too, am a slave to my app. Not that I would ever make a decision based on one whole-day percentage. I pore over three-hourly breakdowns for chances of rain versus minutes of sunshine. If rain is on the cards, I check the probable millimetres. Less than one? I may well throw caution to the wind. Speaking of which, wind speed and direction must also be considered, along with overall and “feels like” temperatures. For the cherry on top, I’ll compare notes with a loved one’s app if they use a different one, quietly mistrusting theirs, and simmering in silent rage if theirs wins.

    I’ll admit, though, that my compulsion to check my app (I long ago chose WeatherPro, which I knew nothing about, but liked its layout and name) is borderline neurotic; I fret over probabilities and outfit appropriateness, when I could simply step outside for real-time hyper-local accuracy. I can lose procrastinatory hours consulting long-range forecasts, or checking the weather in Melbourne (where my sister lives) and holiday destinations I have no immediate plans to visit.

  • The state saw 33 tornadoes last year and severe flooding as researchers say links to climate change are undeniable

    The tornado hit west Ann Arbor at 1.45am on 15 April, passing through Veterans Memorial park, where it knocked several mature oak trees and ripped up baseball field fences before setting its sights on a local ice rink.

    “It came up through the parking lot and, in that time, the pressure differential between the tornado and the air inside the rink collapsed the wall,” said Scott Spooner, a manager at Ann Arbor Parks and Recreation.
