This bird report for the Camargue, Crau and Alpilles (Rhône delta, S. France), covers the years 1980 and 1981. As with the previous reports only the results of censuses and unusual observations are given.
Influence of perennial colonies of piscivorous birds on soil nutrient contents in a temperate humid climate
The influence of perennial colonies of piscivorous birds on soil nutrient contents and accumulation of carbon, nitrogen and phosphorus in a humid climate has been determined by measuring pH, electric conductivity and content of carbon, nitrogen
soil, and the magnitude of increase in nutrient content varied with the bird-dropping density and the age of the colony. In addition, soil influenced by cormorants had a higher electric conductivity compared to the control reference and can
Développement à contre-sens: un aménagement hydro-agricole qui n'a pas donné les résultats escomptés (réseau agricole du PC 23 BIRD, cuvette de l'Alaotra)
Le problème de l'eau et de sa répartition dans les rizières aménagées du PC 23 BIRD (lac Alaotra) vu du côté du paysan et du côté du technicien. (OC).
This bird report follows on from those covering the years 1950-1975. As in the past the area principally concerned is the Camargue and the neighbouring Crau and Alpilles (France, Bouches-du-Rhône). The species mentioned are those which are regularly

processes have biological implications on both national and international levels. The Sahelian biotopes hold a number of endemic biological assets and constitute the main wintering ground for a significant number of Palearctic migratory bird species.
Bird counts and habitat description were carried out using descriptors of natural and man-modified environments to characterize heterogeneous landscapes, at the Mont Pilat Regional Park on a grid of 212 sample points processed by multivariate
The bird and large mammals remains are here examined. All the species recognized in the Jebel Irhoud fauna present a great coherence from an ecological point of view and are indicative of a steppic environment. The Jebel Irhoud fauna differs clearly
