Population justification: The species's population is believed to number 5,000-10,000 individuals (T. Dodman in litt. 2002), roughly equivalent to 3,300-6,700 mature individuals. Surveys at the Tana Delta in Kenya produced counts of 3,000 individuals in 2010, 3,000 in 2019, and 2,500 in 2020 (R. Nussbaumer in litt. 2021). The species is monotypic (Maclean and Kirwan 2020) and due to its migratory behaviour, it is assumed that all individuals have an ample opportunity to mix, and therefore it is assumed to function as one subpopulation.

Trend justification: The population is inferred to be undergoing a continuing decline owing to widespread loss and degradation of wetland habitats in Madagascar (Delany et al. 2009; Kull 2012; D'Urban Jackson et al. 2019), and the degradation of the Tana Delta in Kenya as a result of development (RSPB 2014). Data for this species is difficult to analyse, but there is evidence of it declining in Kenya (C. Jackson in litt. 2021). The likely rate of decline has not been quantified.
