The aim of this paper is to summarize our knowledge of the birds of the Bloemfontein area, Free State, South Africa. It presents data on the status, distribution, population densities and habitat of the birds of this area, during the years 1977-2000 (with a special emphasis on the years 1993-1998). Both published and unpublished data are analysed. Population densities were estimated mainly using the line transect method and territory mapping method. For most fairly common, common and very common species, data on population densities are provided, while for 19 species (mainly rare or very rare), distribution maps of their occupied territories are presented. A total of 324 bird species were recorded. Breeding birds comprised 60.2% of the overall species (195), while non-breeding birds made up the remaining 39.8% (129). Among the breeding species, most (55.9%) were residents throughout the year, 3.1% were intra-African migrants and 1.2% were nomads. Non-breeding birds were represented by Palearctic migrants (35 species, 10.8%) classified as vagrants, irregular and regular visitors; and African non-breeding species (94; 29.0%), which were mainly vagrants. Among the breeding species, most were rare or very rare (100 species, 56.4%). Only 24 (12.3%) of them were very common, nine of which were non-passeres and 15 passeres. The main threat to birds in the Bloemfontein area is intensive agriculture. Some suggestions and recommendations are given for more effective and efficient bird conservation in this important area.
