Old World Warblers (Sylviidae)

Greater Swamp-warbler (Acrocephalus rufescens) - HBW 11, p. 633

French: Rousserolle des cannes German: Papyrusrohrsänger Spanish: Carricero Rufo
Other common names: Rufous Swamp-warbler/Cane-warbler, Long-clawed Papyrus-warbler

Taxonomy: Bradypterus rufescens Sharpe and Bouvier, 1876, Landana, Cabinda, Angola.
Genetic study suggests that this species may form a monophyletic clade with A. brevipennis, A. gracilirostris, A. newtoni, A. rodericanus and A. sechellensis; these sometimes considered to comprise a separate genus, Calamocichla. Birds from NW & SW Uganda, described as respective races niloticus and foxi, considered indistinguishable from ansorgei. Four subspecies recognized.
