First published in 1956, Swifts in a Tower still offers astonishing insights into swifts' private lives along with thoughts about their life style and wider issues. Now more than sixty years later swifts have been studied even more thoroughly, with technology unimaginable in the 1950s. This continues to reveal even more of their secrets, so this edition, published in association with the RSPB for their Oxford Swift City project includes a new chapter by Andrew Lack, bringing the story of this remarkable bird into the 21st Century.
