Migration, stopover and moult of the Great Reed Warbler Acrocephalus arundinaceus in Ghana, West Africa

We studied Great Reed Warblers Acrocephalus arundinaceus at two localities in Ghana during the winter. In the north (Tono), the birds arrived from late September and conducted a rapid moult soon after arrival. Towards the end of moult, birds accumulated fat and disappeared from the site. In the south (Tafo), birds arrived from mid‐November in fresh plumage. This seemed to be the final wintering area as birds stayed there during the winter. In March‐April they again accumulated fat, although only small amounts, before spring migration back to breeding areas.
