Swift Thinking

The little cottage sits settled in a small village with a meandering river making its way through pastures, woodland and water meadows, overlooked by rolling hills of fields carpeted in yellow oil seed rape or the more muted dun colour of wheat. In those fields not given over to agriculture sheep roam munching on lush green grass their lambs frolicking by their sides. The chalky white and deep purple blue of the flint walls of the cottage glared in the bright sunlight that blazed in a deep azure blue sky. Soaring purposefully across this sky, silhouetted against the blue, is a small bird with crescent shaped, pointed wings. One, two, three followed by more. The group swoops low, skimming around the cottage with a whoosh of air and a piercing scream, which for me is a quintessential part of the British summer. It is the swift. A bird that spends its entire life on the wing. On leaving the nest it will remain in flight, heading south to Africa and back, eating, sleeping, socialising, all without touching the ground until two years later when it touches down in a nesting hole.

The birds skim over the immaculate flower beds and vegetable plots, the sweet scent of sweet peas lifts into the air. Around a gnarled apple tree that has stood centre stage in the lawn for as long as I remember, up and over the hedge and off down the road. It is not long before they return, once again skimming the garden but this time making a beeline for the house. They dip a little lower before heading vertically up and landing on the wall just under the eaves. A quick scurry up the wall with sharp claws and the bird disappears into the roof. Here in the dark cool roof space, amongst the aging beams the swift has its nest.

With the bird safely ensconced we quickly set up nets. Recent work has shown that swifts can spend hours in the nest hole before heading off to feed. It is generally hard to catch swifts, they are such fast, agile and high flyers. So netting a nesting site is one of the only options to catching them, but there are strict guidelines to doing so.  But why go to the effort of trying to catch them? Well the UK population is in decline, and the bird is now Amber Listed. The reasons as with many population declines are multi-faceted but one big reason for swifts is home improvements. The demolition and renovation of old houses often results in nesting sites disappearing or being blocked. Given that the species is site-faithful, returning to the same nest site year after year, and do not colonise new sites easily, numbers have subsequently dropped. To have swifts nesting in your house, for me, is therefore something very special. Ringing aims to help establish where birds are wintering, to understand migration routes and juvenile dispersal. Repeated visits over a number of years to a nest colony also helps to understand that site-fidelity.

And so we wait, patient, drinking Granny’s juice, sitting in the little kitchen I have sat in since I was a child. A room that has barely changed as the world grows older around it. Forever glancing out the window finally we are rewarded, not once but three times!

A beautiful swift

There it was, in the hand, with beautiful long curved wings, sooty brown with a pale chin, a small forked tail. Bright, dark eyes, and a tiny bill but large gape. Pin sharp claws at the end of short feathered legs. So with a new ring fitted and all the biometrics taken, each is released, soaring off once again into that blue sky, circling high and away. 

Me, Granny B and a swift

There's a swift in my kitchen

It was one of those days at work, the one where you come home and let it all out in a big ‘rant’ and feel a lot better for it. We all have them. For us the location is usually the kitchen as I rant and raid the cupboards for cheer me ups, and Lee stands listening patiently. This time we had ‘talked’ and I had raided, when I noticed a cardboard box sat on the work top. Lee having made no mention of it to this point, I casually lifted the lid curious to see what was inside. Peeking in, I turn and say ‘what is a swift doing in my kitchen?’

A little weak, our swift when we picked him up

In the box clinging to kitchen paper is a small, dark brown bird with beautiful long wings. A swift. Their sound to me typifies the British summer as they scream through blue skies, dipping and diving, twisting and turning. The ultimate high flier, on leaving the nest the swift spends the rest of its life on the wing. It returns only to ‘land’ in order to breed, everything else, eating, sleeping, mating, drinking, preening is done whilst it soars across the skies.

So what was one of these beautiful birds doing in a box in my kitchen? Occasionally as with any species, swifts get themselves into a bit of a pickle and need our help. In this case, this bird had been found in a kitchen sink having possibly been trapped for a couple days. The finders had taken it to the BTO and Lee had brought it home. Week from lack of food and dehydration, we were not sure it would survive the night let alone have the strength to fly. While we were able to give the bird water finding airborne insects proved a little trickier.

The next morning and there was a lot more movement coming from the box and our friend seemed a little more lively. There was only one way to find out whether it was ready to fly.

Out in the open space of the park, with swifts reeling overhead, careening around the houses, came the moment of truth. With a gentle push the bird was airborne. For a heartbeat it hung there, with the two of us ready below to catch it should it fall back to earth…. One, two flaps of those wings and it seemed to gain strength. Rising up like a feathered angel, wing beats getting stronger and stronger our little swift rose up in circles into the blue sky. Suddenly a flash mob of six or seven swifts joined in, and the group soared away over trees and houses....

Wild and free, a swift soars across the summer skies
