The accumulation of selected N, K, and P forms in soils within three perennial colonies of black cormorant (Phalacrocorax carbo sinensis) and grey heron (Ardea cinerea) located in northern and eastern Poland were investigated. Soil samples were collected beneath the nests from the most representative for each colony plots.

Experimental infections of laboratory-raised birds supported field data indicating that Common Mergansers (Mergus merganser L.) (prevalence = 20.8%, mean intensity = 3.2) and Red-breasted Mergansers (Mergus senator L.) (prevalence = 4.0%, mean intensity = 1) are important hosts of Eustrongylides tubifex in Ontario.

Since 1971, when the Grevelingen estuary was turned into a 108 km2 saline lake, the number of foraging piscivorous birds has increased significantly. Up to 7000 to 10 000 Great Crested Grebes may be present on the lake, representing about half of the northwestern European breeding population.

Experimental approach on the impact of piscivorous birds on a littoral extensive fish-farming
1993Une étude quantitative de la prédation par deux espèces d'oiseaux piscivores a été réalisée dans un bassin situé dans un ensemble de réservoirs à poissons. Deux enclos, l'un protégé par des filets et des fils, l'autre accessible aux oiseaux, ont été étudiés.
