Taxonomy

Taxonomic note
Acrocephalus arundinaceus and A. orientalis (del Hoyo and Collar 2016) were previously lumped as A. arundinaceus following AERC TAC (2003), Cramp et al. (1977-1994), Dowsett and Forbes-Watson (1993) and Sibley and Monroe (1990, 1993).

Population justification: In Europe, the breeding population is estimated to number 2,600,000-4,680,000 pairs, which equates to 5,190,000-9,360,000 mature individuals (BirdLife International 2015).

Trend justification: The population is suspected to be in decline owing to ongoing habitat destruction (del Hoyo et al. 2006), although in Europe, trends between 1982 and 2013 have been stable (EBCC 2015).
