Swifts and Us


Synopsis


Swifts live almost entirely in the air. They eat, drink, sleep, mate and gather their nesting materials on the wing, fly thousands of miles across the world, navigating their way around storms, never lighting on tree, cliff or ground, until they return home with the summer.

Sarah Gibson has written a fascinating story of discovery, exploring what is known about these mysterious birds, their ancient ancestry and how they have been regarded through history. But the swifts are in real danger: often unintentionally, we are sealing our homes against wildlife of any kind. Cracks, gaps and crevices which for thousands of years have offered nesting space in buildings, are being closed off, while new housing rarely offers entry holes for nesting birds. Loss of breeding places is considered to be a significant factor in the steep decline of these birds over the last twenty years.
 
Thankfully, there are people in the UK and across Europe striving to ensure a future for swifts. Their actions and stories are woven into the narrative, demonstrating how change is brought about by passionate, determined individuals, whose actions show that everyone can do something to keep these superb birds screaming through our skies.

Summary

Chapter 1: The Extraordinary Swift

* Swift physiology and adaptations: their incredible aerial maneuvers, long lifespans, and high-altitude migrations.
* Example: A swift can fly at speeds of up to 70 mph and can spend its entire life in the air, sleeping and feeding in flight.

Chapter 2: A Swift's Eye View

* The world as a swift sees it: their visual acuity, color perception, and ability to perceive magnetic fields.
* Example: Swifts have a nearly 360-degree field of vision and can detect insects against the sky even at great distances.

Chapter 3: The Swift's Song

* Swift communication: their unique screams, calls, and twittering.
* Example: Swifts create a chorus of high-pitched screams that reverberate through their nesting sites, believed to signal their presence and establish territory.

Chapter 4: The Swift's Nest

* Swift nesting behavior: their colonial lifestyle, nest-building techniques, and parental care.
* Example: Swifts build intricate nests out of saliva and mud, which harden into a durable structure that can withstand rain and wind.

Chapter 5: The Swift's Migration

* Swift migration patterns: their incredible journeys, timing, and navigation abilities.
* Example: Swifts can migrate up to 5,000 miles to their wintering grounds in Africa, using the sun, stars, and Earth's magnetic field as navigational aids.

Chapter 6: The Swift's Decline

* Threats to swifts: habitat loss, climate change, and pollution.
* Example: The demolition of historic buildings where swifts nest has led to a decline in their populations in many cities.

Chapter 7: Swifts and Us

* The cultural and ecological importance of swifts.
* Example: Swifts consume large numbers of insects, including pest species, providing a valuable ecosystem service.

Chapter 8: Swifts in the Modern World

* Swift conservation efforts: nest box programs, building renovations, and public awareness campaigns.
* Example: In the UK, the Swift Conservation Group has installed thousands of nest boxes to support swift populations.

Chapter 9: The Future of Swifts

* The challenges and opportunities for swift conservation.
* Example: Climate change is predicted to affect swift migration patterns, but the implementation of conservation measures can help mitigate these impacts.
