The Influence of Synchronous Breeding, Natal Tree Position and Rainfall on Egret Nesting Success

Reproductive ecology of the Cattle Egret (Bubulcus ibis) at Sidi Achour, north-eastern Algeria

“…An analysis of breeding success between the two areas over different reproductive seasons is needed to resolve the issue. Our results, limited to clutch size, are similar to that reported by several workers (Siegfried 1972a, Ranglack et al 1991, Baxter 1994, Si Bachir et al 2000. In contrast, in Moroccan colonies, Hannane (1981) andFranchimont (1985), both reported differences in clutch size between central and peripheral nests.…”

Vertical nest stratification and breeding success in a six mixed-species heronry in Taeseong, Chungbuk, Korea

“…Usually, the center of colonies is characterized by low predation risk and high reproductive success (Hafner 1980). However, if no differences are observed in the reproductive performances between the central and peripheral nests (Ranglack et al 1991;Baxter 1994), the peripheral sites may be beneficial in that the severe competition from neighbors, especially a large colony of heterospecific species, such as the great egrets, can be avoided.…”

“…data), the Ebro Delta (Ruiz et al 1981) and the Valencia Albufera (Prósper & Hafner 1996) are available. Factors affecting the breeding success of the species have been widely studied in these recently colonized areas (Baxter 1994, McKilligan 1997. However, few data exist from those areas with well-established colonies (see however Ruiz et al (1981) and Maddock & Baxter (1991)).…”
