Personal account of bird-watching in inner London in the mid 1920s, from this distinguished ornithologist and conservationist, based on his own original observations. Separate chapters cover London's ducks and gulls, the flylines over London, the birds of Kensington Gardens, and bird protection in London. An appendix by Roy Sanderson, one of the last Official Observers of Hyde Park and Kensington Gardens, brings the history of the birds of the parks up to date.
