Population justification: The known population at seven recently discovered sites in Lara and Falcón in 1996 was c.35-94 pairs (Boesman 1997). There are nearly 25 additional known sites, and further surveys are likely to discover additional localities, so the total population is probably several times the known figure (Boesman 1997, Sharpe et al. 2001, V. Morón-Zambrano in litt. 2012). Therefore, although the population at known sites was thought not to exceed 250 individuals in 2008 (Ascanio and Sharpe 2008), the total population is placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.
Trend justification: A slow and on-going population decline is suspected to be taking place owing to the continued loss and degradation of wetland habitats.
