Water of Leith Swifts

Water of Leith Swifts Advising on installs of high tech new homes for swifts along the urban WoL corridor and Edinburgh.

Pls get in touch if you would like more info on providing safe new homes for swifts, swallows and house martins!

Having spent the entire evening outside watching the local swifts I have just now found a new natural swift nest behind a gutter visible from my back garden❤️

24/06/2026

A lovely warm evening and there are lots more swifts zooming around over the colony.

And…. Drum roll…. they are getting closer to my new swift boxes 😀

In this video from the Canonmills swift colony we see a quick fly by past my new boxes and then the same group decide to double back and pester the natural swift nest site at the other end of my back garden.

Reviewing footage from the last few days and this video from a couple of evenings ago stood out with the moon in the background and the swifts appearing to circle it while screaming around above their colony.

While Edinburgh is still waiting for its influx of juvenile swifts that will be searching for their forever nest sites the heatwave down south has caused a big increase in swift numbers over the last few days and it looks like the second wave of swifts is now well underway.

Edinburgh seems to have decent weather for the week ahead although turning a bit cooler in a few days. Hopefully it will be enough to entice the second wave of swifts and for them to hang around for the rest of the summer🤞

Amazing light for 10pm and lots of commotion amongst the Canonmills swift colony before bedtime.

About 1 second in and one of our resident swifts enters its natural nest site in a hole by the gutter and downpipe. It is then harassed at the entrance hole by all the other swifts.

The resident swift can be heard screaming warnings to the other swifts to get away from its nest.

Seeing these behaviours play out is just such a privilege given how rare these birds now are.

No swifts no party 🎉

Shame about the footy last night but at least we finally have some blue skies ☀️

The locals enjoying the milder weather. They really do move very swiftly in windy conditions 🥰

Some relaxing footage of the Canonmills swifts feeding above their colony this morning. I could watch these guys all day if my neck did not get so sore!

The best times of day to see swifts flying around their colonies are early morning and late evening and they tend to disappear for large chunks during the day.

What a relief! The Canonmills swifts are back in good numbers ❤️

It may be raining but it’s not as cold this morning and we seem to be back in business with “bangers” (younger swifts looking for their first ever nest site by banging into gutters to check behind them for entrance holes at the very tops of the walls which lead them into the attic) at the Canonmills swift colony. This will likely be happening all over Edinburgh not just Canonmills. Edit: it is also a good indicator of an occupied swift nest very nearby as young swifts enjoy harassing active nests!

If anyone sees the swifts behaving like this let us know and we will go and investigate it further. It is likely to be an excellent building choice for swift nesting boxes or bricks.

Keep an eye out for swifts around the city and if you have nest boxes and a swift caller it’s a good day to turn the caller on again (but keep the speaker dry somehow!)

THE HOLE IN YOUR WALL WAS NOT EMPTY.
IT WAS THE ONLY DOOR MY CHICKS KNEW.

You may look up at an old house and see only a crack.

A gap under the eaves.

A small dark hole in brick or soffit.

Something easy to seal.

Easy to repair.

Easy to make neat.

To us, it is a defect.

To a swift, it can be an address remembered across continents.

I am a common swift.

I spend most of my life in the sky.

I feed there.

Drink there.

Sleep there.

Travel there.

Cross countries there.

Cross deserts there.

Cross seas there.

And after all that distance, I return not to “a roof.”

Not to “a street.”

Not even to “a house.”

I return to one opening.

One narrow entrance.

One exact little darkness where my chicks wait.

They do not know another exit.

They do not know another sky.

If that hole is sealed while they are inside, the wall does not simply become tidier.

It becomes a closed mouth.

A blocked future.

An adult may keep circling.

Calling.

Landing on the brick.

Clinging near the place where air used to be.

Again.

Again.

Again.

Because instinct does not understand fresh mortar.

Because love does not know what “renovation” means.

And inside, the chicks do not cry to the whole street.

They wait.

They trust the doorway they were given.

That is what makes this cruelty so quiet.

Please, before repairing roofs, soffits, fascias, eaves, vents, or cracks in spring and summer, check for nesting swifts.

If swifts are screaming around a building, entering holes, or circling one wall repeatedly, stop and seek wildlife advice.

Avoid sealing active nest sites during the breeding season.

Where repairs are needed, use timing and mitigation.

Install swift bricks or nest boxes.

Leave access where possible.

Because the hole in your wall was not empty.

It was the only door my chicks knew.

And after flying half the world to return,

I came home

to find that home had been erased with a trowel.

Ahh, another lovely summers day on the Scottish east coast. A balmy feels like 11 (it feels colder than this!) with rain...

Ahh, another lovely summers day on the Scottish east coast. A balmy feels like 11 (it feels colder than this!) with rain this morning 🥶

Sorry for the depressing message but it’s more bitterly cold and wet weather for the week ahead (see the photo). I can’t remember a worse start to a summer - it’s even worse than two years ago.

What swifts remain are only here because they are sat on eggs or may have fresh hatchlings and can’t escape. They are likely having to expend valuable energy resources travelling substantial distances to find what few insects are available. They are not making any of their traditional social calls around the colonies and are in a desperate struggle to survive and raise their broods.

There are no large groups of younger swifts screaming around and prospecting for new nest sites around the Stockbridge and Canonmills colonies as we would expect to see at this time of year.

Without tempting fate some long range forecasts are now suggesting no sustained warmth for Edinburgh until August. I really hope for the swift’s sake this is not accurate.

In a normal year the swifts arrive in Edinburgh around the first week of May and would be leaving at the beginning of August having successfully raised their broods.

It will be interesting to see how this pans out as two years ago when we had a really cold start to summer there were still late breeding swifts hanging around the colonies at the end of September.
