The main section of this book contains a systematic review of all 309 species of birds that have been recorded in Northamptonshire. It includes references to their past and present status. Previous publications of Northamptonshire county bird lists have been by Lord Lilford in 1893, L.S. Taylor in 1959 and B. Webster & G. Wood in 1976. An effort has been made to try to pull together totals of birds seen as well as the number of records. The original copy of this book was first published privately in 1990 and was correct to 31/12/1989. This virtual book will be updated each year. All totals are correct to 31/12/1997.
