Breeding biology and ecology of the White Stork (Ciconia Ciconia) in the valley of the Oued Sébaou (Kabylia, Algeria).
Boukhemza, M., Boukhemza-Zemmouri, N. & Voisin, J.-F.
The fecundity and breeding success of the White Stork Ciconia ciconia were estimated from observations conducted from 1992 to 1996 in the valley of the Oued Sébaou, Kabylia, Algeria. During this period the Kabylian White Stork population increased, passing from 234 to 292. The proportion of those which reproduced successfully slightly varies from one year to another, remaining higher than 90%, except in 1992 (82.5%). The total number of fledged young increased rapidly between 1992 and 1993, then was steady from 1993 to 1995. For this period however, the breeding success decreased regularly (from 2.51 fledglings/pair in 1992 to 2.28 in 1996), which could indicate the beginning of saturation of the area (medium). From 1992 to 1996, the average density in the valley of the Oued Sébaou increased from 25.47 to 31.78 pairs per 100 km² of arable land. In spite of these encouraging results, a negative difference (-83.28%) still remains between 1955 and 1995. The increase of 54% between 1995 and 2001 observed by Moali-Grine et al. (2004) between 1995 and 2001 still has not completely eliminated this difference.
