Table 1 Dependent variables considered in this study and their description, as well as the model species considered for each of the season (breeding: 15th April to 15th July, post-breeding migration: 16th July to 15th October and wintering: 15th November to 15th February) that were included in the statistical analyses (all = every sampled bird of all species)

From: Individual and demographic responses of a marsh bird assemblage to habitat loss and subsequent restoration

  2. 1 During breeding season, this parameter was considered as an index of breeding success. 2 Differences in sex determination cannot be addressed by observational procedures for the most common migratory species at the study area (Svensson 1992; Jenni and Winkler 1994)
