The breeding ecology of common coot Fulica atra was investigated at El-Golea Lake, in the northern part of Algerian Sahara, where the breeding season was comparatively short, during three months. The distinct habitats within the lake used by common coots for nesting are associated with Typha angustifolia (96%) and Scirpus lacustris (04%), the vegetation covers the density that varies between 30% to 80%. The mean clutch size was 5.6 ± 3.2 eggs (N = 45 clutches) and the laying occurred mainly in April, but continued until the end of May. The Breeding success rate was (75.55%) with the predation rate of (72,72%), and clutch desertion of (27,27%). The effects of disturbance on the breeding success of this water bird and the necessity to protect this species and also this wetland were discussed in the present study.
