Abstract

Over five years (1987–1991), 238 neophyte stands in north-west Croatia (190 ha) with a total of 390 Marsh Warbler (Acrocephalus palustris) territories were investigated during the nesting season. As neophyte vegetation consisting of Solidago gigantea and Helianthus tuberosus are predominantly present near streams in north-west Croatia, Marsh Warblers usually choose these plant communities for nesting. The nest usually can be found near higher plants like bushes, solitary two-year old and perennial plants, which males also use as singing places. The main woody plant species of these singing places were found to be Salix alba, S. cinerea, S. purpurea, Alnus glutinosa and others. Males also sing on old, withered previous year’s herbaceous plants distinguished by their greater height than the surrounding vegetation (Solidago gigantea, Helianthus tuberosus, Urtica dioica, Artemisia vulgaris etc.).
