Vertical and horizontal distribution of five wetland passerine birds during the postbreeding migration period in a reed‐bed of the camargue, france

Abstract

The vertical and horizontal distribution of five wetland passerines in a reed‐bed in the Camargue was studied during the postbreeding migration period. There was more evidence of vertical segregation between the species than horizontal separation. Comparisons are made with other studies in Europe and, for three species, the vertical distribution was similar in the breeding and postbreeding migration; for Reed Warbler, Moustached Warbler and Great Reed Warbler it seems that the vertical selection is almost identical in these two periods. © 1990 Taylor & Francis Group, LLC.
