People all over Britain and Europe have long welcomed the arrival of swifts and swallows as a promise of summer being just around the corner. And with their similar long wings and dashing flight, it is perhaps understandable that we often confuse the two birds. After all, they have much in common: both feed on flying insects, both breed around buildings, and both are long-distance migrants that spend winter in Africa. But appearances can be deceptive. Swifts and swallows are completely unrelated birds that have adapted through evolution to survive in similar ways. In Spotlight: Swifts and Swallows, Mike Unwin reveals their fascinating lifestyles, explains how and why they have acquired their similarities, and ways in which we can help protect them.
