For many of us the most welcome sound we’re likely to hear along an urban street will be the high-flying squeal of the swift.
Swifts are among the latest of our summer birds to return, with just a few pioneering individuals recorded before late April, and many not arriving until well into May.
We often hear their distinctive screams before we see them, high over our rooftops or racing at chimney-height along the streets.
More than perhaps any other bird swifts are truly creatures of the air. They spend the great majority of their days (and nights) on the wing, landing only to raise young.
Indeed their Latin name ‘apus’ means ‘without feet’, which is inaccurate but an understandable mistake, given their tiny landing gear that’s hardly ever on show.
Early in the season it’s the adults that can be heard and seen, often in groups, reclaiming their streets. Later on, in July, they are joined by their scalier-looking offspring for practice laps and feeding sorties, again shrieking away as they tour the neighbourhood.
Unlike the similarly aerodynamic swallows and martins, they raise only one brood, and are among the earliest of our birds to head back South.
Swifts have undergone one of the sharpest recent declines of any of our birds, with more than half disappearing between 1995 and 2016. One of the reasons appears to be a lack of suitable breeding sites, as their favoured eaves and roof cavities are lost to renovations.
One solution to this may be the way we build houses. While there’s nothing brick-like about a swift, the placement of hollow ‘swift bricks’ set high into the walls of new homes could create many new places to nest. And not just for swifts, but for house sparrows, starlings and other species struggling to make a home in neighbourhoods that have become a little too tidy.

Ever heard a Wood Warbler?
🎶 This Saturday: live birdsong with Ben Porter 🎶
Listen for spring woodland birds with us on Saturday 21st May.
On this special edition of Up With The Birds, we will be guided by naturalist, photographer and birdsong educator Ben Porter, who will be aiming to bring us live sounds from the woods of mid Wales, such as the songs of pied flycatcher, wood warbler and redstart.
The call is free and all are welcome.
