Population justification: A recent estimate put the total population at c.2 million adults (Maclean 2004, Maclean et al. 2013), roughly equivalent to 3 million individuals in total.

Trend justification: Maclean et al. (2013) estimate that, between 1984–1987 and 1999–2001 the areal extent of papyrus in its range declined by 6.7% from 1,643 to 1,532 km2. This species is estimated to have decreased by 20.6% (80% CI: 7.7-42.5%) over three generations, based on a comparison of data from 1984-1987 and 1999-2001. Rates of population decline were estimated by assuming that relationships between density, occurrence and habitat variables derived from 1999–2001 data, were the same in 1984–1987, and assumed a constant geometric annual rate of decline. The population is therefore estimated to be in moderately rapid decline based on estimated losses of papyrus swamp habitat and decreases in local population density (Maclean et al. 2013).
