Spring returns and with it the birds. But it also brings throngs of birders who emerge, binoculars in hand, to catch a glimpse of a rare or previously unseen species or to simply lay eyes on a particularly fine specimen of a familiar type. In a delightful meditation that unexpectedly ranges from the Volga Delta to Central Park and from Charles Dickens's Hard Times to a 1940s London burlesque show, Jeremy Mynott ponders what makes birds so beautiful and alluring to so many people.
