| Population justification: The population is estimated to number 2,000-6,000 individuals, roughly equivalent to 1,300-4,000 mature individuals (T. Dodman in litt. 2002). | ||||
| Trend justification: Whilst the species remains fairly widespread, populations are low, and increasing exploitation at breeding sites is likely to increase the rate of population decline (ZICOMA 1999). As a result, a rapid and on-going population decline is suspected. One site was reported to have 232 breeding individuals in 2007 but zero in 2008 (J. Ramanampamonjy in Anon. 2008). The recently discovered breeding population on Mayotte is thought to be increasing (Rocamora 2004; in Ndang'ang'a and Sande 2008). In 1990 the species was considered to have undergone a significant recent decline (Burger et al. 1990). | ||||
