Résumé :

London's birds have been studied in detail for about 120 years. Stanley Cramp was co-author of two important papers in British Birds looking at the birds of Inner London during the first half of the twentieth century, the first of which summarised records from 1900 to 1950, and provided a baseline for future studies. The London Natural History Society has since completed two atlas projects to map breeding bird distribution and is close to completing a third atlas project. This paper looks at the changes that have occurred since the period covered by Cramp's first article (1900-50). An overview of changes in Inner London is followed by more detailed accounts of selected species groups. The number of species nesting annually in Inner London has increased steadily, from around 32 in 1950 to about 60 today. Waterbirds have done particularly well, and the successful return of raptors to the city has also been welcome. The fortunes of passerines have been mixed.
