Résumé :	The foraging range and principal feeding areas of White-chinned Petrels breeding at South Georgia were determined using satellite telemetry. Foraging trips during incubation lasted 12-15 days and covered 3000-8000 km and 2-11 days and 1100-5900 km during chick-rearing. Adults covered less distance per day during chick-rearing (71 km) than during incubation (91 km) but the proportion covered at night (47%) was the same. Mean (31-34 km/h) and maximum (80 km/h) flight velocities were similar during both periods of the breeding season and during day and night. Between incubation shifts, White-chinned Petrels travelled to the Patagonian shelf during chick-rearing they foraged more extensively. Most locations were between 30 degrees to 55 degrees W and 52 degrees to
