Résumé :	Little is known about the biology of Abdim's Stork Ciconia abdimii, in Benin. I studied the nesting of this intra-African migrant in the wet season of 1996. Breeding pairs arrived at the end of March 1996. Seven nest sites were found, involving 92 pairs; the largest colony was of 51 pairs. The storks used five different large tree species for nesting. Egg-laying began in early April and lasted until 2 July. Most clutches were of 3-4 eggs. Incubation lasted 28-29 days. A total of 196 young storks fledged (all of which were ringed), representing a success rate of 76.5% per egg laid and 86.0% per egg hatched. The last storks left the colonies on 9 September 1996, 164 days after the first ones arrived on 30 March. The species is threatened in Benin by human persecution and by widespread pesticide use: it urgently requires official protected status.
