Population justification: None remain. The species is known from 18 or 19 specimens collected between 1939-1964 (Fjeldså 1993). It was still abundant on Lake Tota in 1945 (Borrero 1947), but numbers crashed in the 1950s due to various factors and the last confirmed record was in 1977. Because intensive studies in 1981 (Fjeldså 1993) and 1982 (Varty et al. 1986) failed to find the species, it is now considered Extinct (Collar et al. 1994).
