Résumé :	The duration of primary moult of adult Cape Turtle Doves Streptopelia capicola was estimated to be 192 days. 23 November was the estimated mean starting date. with 95% of birds starting within 88 days of this date. The mean body-mass of adults was 148 g and of first-year birds was 130 g. In residential areas, Cape Turtle Doves were trapped less frequently than Laughing Doves S. senegalensis: at most rural sites, Cape Turtle Doves comprised about two-thirds of the catch. On a dairy farm. where doves were attracted to cattle feed, 1% of doves were Cape Turtle Doves. The emerging pattern is that Laughing Doves predominate at sites where food is provided on a long-term basis.
